July 20, 2022 by Aylish DeVore

Our world continues to become more interconnected than ever due to the innovative advancements in telecommunications. All types of industries are collaborating to deliver disruptive technologies like artificial intelligence (AI) and smart homes – making it crucial for those beyond the telecom space to understand this high-tech terminology. Each of our lives are influenced by our ability to connect with others, whether you work in finance, recruiting, manufacturing, healthcare, or even agriculture. Something as simple as Wi-Fi is a tool delivered by the telecom industry that we all need to do our jobs, no matter the field. According to market analysis, the telecom industry is predicted to grow 5.4% annually between 2021 and 2028. That’s a faster growth rate than the automotive, construction, insurance, and agriculture industries! No wonder it’s been hard to keep up with the ever-changing telecom terms.

To shed some light on this industry jargon and bring you up to speed on some recent advancements, Blue Signal created a glossary of the most common and useful telecom terms. These telecom terms will help you better understand what goes into keeping us all connected – and possibly provide some knowledge to help you stand out with a future client or employer. Read on to learn about 5G, VPNs, TCP/IP, and more. For the full list of 80+ telecom terms, click the link below to download our guide.

Glossary of Telecom Terms Pocket Guide Cover

Top 20 Telecom Terms:

  1. 3G/4G/5G: Third-, fourth-, and fifth-generation wireless capabilities that allow for faster and broader access to information and services via mobile devices.
  2. Bandwidth: The range of frequencies in a communication channel. Analog communications measure bandwidth in Hertz, whereas digital communications use bits per second (bps).
  3. Broadband: A high-capacity transmission technique that allows for the communication of a large amount of information over a wide range of frequencies.
  4. Carrier: Vendor of transmission services operating under terms defined by the FCC as a common carrier. Owns a transmission medium and rents, leases, or sells portions for a set tariff to the public via shared circuits. (AT&T, Sprint, MCI, Ameritech, etc.)
  5. Fiber Optic Cable: Glass strands used to transmit light signals for cell phone and Internet connections. These cables allow for connection speeds 10 to 100 times faster than copper wire.
  6. Firewall: A barrier device placed between two separate networks. A firewall can be implemented in a single router that filters out unwanted packets or it can use a variety of technologies in a combination of routers and hosts. Today, many firewalls combine filtering functionality with Network Address Translations (NAT) functions.
  7. Gateway: A network element that performs conversions between different coding and transmission formats. The gateway does this by having many types of commonly used transmission equipment and/or circuits from different carriers to provide a means of interconnection.
  8. Local Area Network (LAN): A group of computer and peripheral devices that are connected in a limited area such as a school, laboratory, home, or office building.
  9. Network: Any connection of two or more computers that enables them to communicate. Networks may include transmission devices, servers, cables, routers, and satellites. The phone network is the total infrastructure for transmitting phone messages.
  10. Open Network Architecture (ONA): The overall design of a carrier's basic network facilities and services to permit all users of the basic network, including enhanced service providers, to interconnect to basic network functions on an unbundled and "equal access" basis.
  11. Private Branch Exchange (PBX): A private telephone exchange that serves a particular organization or business and has connections to the public telephone network. Newer PBXs have features that allow for data and video communications as well as voice.
  12. Radio Frequency (RF): A measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz. With the use of antennas and transmitters, an RF field can be used for various types of wireless broadcasting and communications.
  13. Router: A device or setup that finds the best route between any two networks, even if there are several networks to traverse. Like bridges, remote sites can be connected using routers over dedicated or switched lines to create WANs.
  14. Small Cell: An umbrella term used to describe a miniature radio access point (AP) or wireless network base station with a low radio frequency (RF) power output, footprint, and range. They enhance cellular network coverage and capacity in areas where use demands are the highest.
  15. Switch: A mechanical or solid-state device that opens and closes circuits, changes operating parameters, or selects paths for circuits on a space or time division basis.
  16. Telecommunications: Communicating over a distance. Use of wire, radio, optical, or other electromagnetic channels to transmit and receive signals for voice, data, and video communications.
  17. Transmission Control Protocol/Internetworking Protocol (TCP/IP): A protocol developed to allow dissimilar devices to communicate across many kinds of networks.
  18. Virtual Private Network (VPN): VPN modules create closed secure tunnels for communication between two firewalled LANs. VPN technology is a common approach used today for providing secure communications over IP networks.
  19. Voice Over Internet Protocol (VoIP): Telephone services provided over broadband Internet connections rather than traditional phone networks.

How Unified Communications Has Paved the Way for Remote Working

December 1, 2021 by Lacey Walters

Many professionals today are familiar with standard UC (unified communications). It has been around for a while and was traditionally used for in-office communications. On-premise PBX allowed you to call up your boss’ office or email a request for printed documents to your secretary. With VoIP (voice over internet protocol), people had calling, messaging, and collaboration capabilities all over an internet connection.  

Today, with this change in the way we “go to work,” unified communications has adapted to meet our remote needs. Taking it a step further, it’s evolved to provide the capability for instant messaging across the globe, instantaneous file sharing through the cloud, and reliable video conferencing to help connect people wherever they may be working. Thanks to UC, we now have better options when it comes to “going to work.”  

 

How Unified Communications Enables Productive WFH Results 

With many companies opting in for UCaaS (unified communications as a service), they are experiencing the best of VoIP without the need and cost of infrastructure. When working from an office, UC depended heavily on fiber connectivity. Today, anyone can work from anywhere given a good internet connection – even wirelessly.  

This UC development means employees are able to bring their own devices (BYOD) and leverage their own computers and mobile devices. This can save employers expensive equipment costs, reduce ramp up periods and time needed to train new hires on equipment, and eliminate the need for installation of fiber or other infrastructure. More importantly however, it’s causing employees to become more efficient and productive. It makes sense that people perform better on the devices they already know how to use. With the ease of use and the effortless adoption, this remote working norm is set to be the #1 thing to stick around from the changes the COVID pandemic made to how we work.  

Not to mention, modern UC is more scalable than traditional data centers. Without the need for servers, telephony equipment, or phone lines – growth is only limited to bandwidth of a user’s internet connection. This makes it easier for hiring managers to grow their workforce by hiring people remotely. In turn, providing UC options really widens the potential candidate pool when hiring.  

 

How Unified Communications Enables Safer WFH Results  

What many people don’t realize is that leveraging UC when working from home actually has benefits that extend beyond working hours. With encrypted communication channels and the endpoint security that comes standard with most UC, people feel more secure sharing their data over personal networks because their work’s unified communications system helps safeguard their network at home. Cybercrime has increased 63% since the start of the COVID-19 pandemic, making network safety a top priority.  

benefits of unified communications

What This Means for the Future of UC 

In simple terms, unified communications is here to stay. It’s estimated that the UCaaS market will surge past $100B by 2024. In order to stay ahead of the game when it comes to the digitization of the workplace, businesses need to consider switching from traditional PBX to UC. In the same effort, those that are early adopters should further build out their UC strategy.  

When it comes to implementing and developing unified communications in any business, Blue Signal has the talent it takes to be successful in this evolving space. Whether you’re looking to support and build out remote teams and WFH policies, or you’re just curious what your first step should be in your UC journey, Blue Signal has your back. Contact our qualified unified communications recruiters today to get started.

How 5G Will Revolutionize the Way You Do Business

January 6, 2021 by Aylish DeVore

By now you’ve probably caught the buzz about this thing called 5G that’s coming to change the world… but what is it really? And what will it mean for your business once it’s here? 5G is the 5th generation mobile network and the new global wireless standard. 5G wireless technology is meant to deliver higher multi-Gbps data speeds, much lower latency, massive network capacity, increased availability, and a more uniform user experience to more users across the globe. Simply put, it’ll make your mobile connectivity faster and more reliable. This technology is a huge breakthrough in wireless tech and some industry insiders have gone so far as to say that the 5G network will be as revolutionary as the printing press, the automobile, and electricity. So the question is, have you thought about how your business will change? In this blog, we’re hitting on all the key features of 5G that will revolutionize the way you do business and how to utilize them most effectively.

Ability to Work From Anywhere

With the recent pandemic and the majority of the nation’s workforce working from home, the capability to connect wirelessly, from any location is more necessary than ever. 5G enables just that; making being chained to an Ethernet cable or within range of a Wi-Fi hotspot a thing of the past. With the power of 5G, users will be able to connect to high-speed connections from just about anywhere. Yes, anywhere. A recent study shows 62% of employees work remotely at least part-time and this number only continues to rise as more employers continue to enforce health and safety precautions. With the abilities of 5G, businesses will be able to allow even more flexibility to their employees when it comes to working locations. In turn, this creates a larger candidate pool as geographical location ceases to be a qualifier for employees. This ease of accessibility is sure to increase morale and create a more relaxed workforce.

Seamless Functionality

With 5G, not only will the connection be vastly available but the functionality will be seamless. Through its fluid capabilities, 5G allows not just remote work but virtual work. The difference? Users will be able to access data, communicate with co-workers, collaborate on projects just as seamlessly as if they were physically in the same room. Remote workers will no longer be held back by needing access to large amounts of data, or a brainstorming session interrupted by poor video connection and lag. Further, with the increased capability, running more advanced technology becomes a breeze. Businesses will be able to access and implement virtual reality, augmented reality, and AI technology into their typical work routines creating a more connected and technologically advanced environment.

5G to Increase Productivity Poll

Increased Productivity

The entire workforce is buzzing in anticipation of the impact 5G will have on the way we function. 91% of US organizations and 88% of small to mid-sized enterprises agree that 5G will increase productivity. As mentioned earlier, lagging connections and download speeds can really disrupt remote and in-office employees’ workflow and attention span. Significantly faster data speeds mean far lower latency while waiting for a file to load, a meeting to start, attachments to download, etc. A big contributor to slow or glitchy connections is an influx of users in a centralized area. 5G allows for up to a million devices per square kilometer, making high-speed connections seamless even in extremely high traffic areas. There is an overwhelming amount of both large and small impacts that will contribute to maximized productivity from every angle. Even something as small as improved energy efficiency will result in prolonged battery life on devices, eliminating time searching for a lost charger or an outlet in a crowded coffee shop.

Improve Company Communication & Culture

Especially in the current state of the world, having a strong company culture is more important than ever to keep employees engaged. Human connection and interaction is key to keeping a positive mindset throughout the office and even more so for employees working at home. Companies are hiring more remote employees, expanding across the country and even the globe. While this leverages several benefits, it also can create some challenges in developing an inclusive company culture and connected dynamic. All of the capabilities 5G will introduce into your business play a role in how you’ll connect and interact internally, no matter your organization’s geographical location. Trust us, boring conference calls will be a thing of the past as the potential of 5G innovations expand to holographic calling, enabling users to view 3D presentations with or without glasses, and interactive meetings utilizing AI technology. Why would you choose to use small chat boxes on computer screens when augmented and virtual reality connectivity will run seamlessly?

It’s clear to see that the power and innovation 5G is bringing will revolutionize the way people do business in a big way. Here at Blue Signal, we plan to utilize many of these advancements in multiple aspects of our business. One area we are excited to embrace is the ability to further empower our remote employees’ flexibility in where and how they work. Blue Signal has a long history of leveraging a geographically diverse team as we’ve had recruiters working from all over the country since our inception. The ability to further advance the way we communicate and engage with each other internally will be a huge initiative in the coming year as we look forward to continuing to nurture our tight-knit company culture. Additionally, the connectivity and seamless functionality of 5G will allow us to better serve our clients and candidates. As the recruiting industry continues to grow, we continue to stay committed to rising above the norm by utilizing the most effective resources, technology, and processes available to us. Reach out to one of our recruiters today to talk about what 5G advancements mean for your workforce and how you can capture these benefits.

2018: The Year of User-Friendly Enterprise DAS

June 7, 2018 by Lacey Walters

A recent industry survey by Coleman Parkes found that properties with excellent in-building wireless coverage technology were worth 28% more than properties with poor indoor coverage. The demand for reliable in-building wireless continues to grow. Many older buildings are constructed from materials that block cell signals and create pain points for building tenants. Even buildings with cellular coverage often lack capacity for today’s normal mobile usage. However, building owners have been reluctant to upgrade because of the perception that a DAS infrastructure investment is too costly. This year, that is changing. High-quality DAS solutions are becoming available for mid-sized businesses.inbuilding wireless

Wireless companies are competing heavily for businesses in the “middleprise” sector: venues between 50,000 and 500,000 square feet. While DAS is the default coverage solution for big venues like stadiums, airports, and large enterprises, a full-scale DAS is not usually cost-effective for midsize venues like hotels, malls, and hospitals. They are big enough to need an in-building coverage solution to boost the indoor signal, because poor coverage affects employee performance, productivity, and even the rent that the building owner can charge. However, traditional DAS solutions are often too large and expensive for these venues. WiFi coverage alone is not enough to deal with high data volume, and VoWiFi is not reliable enough for mission-critical telecommunications.

These midsize enterprises sometimes balk at pulling the trigger on a major DAS installation because of price or complexity. Since many companies have a BYOD policy, their connectivity solution needs to support bandwidth-intensive, multi-operator, multi-band functionality. At the same time, it needs to be cost-effective, secure, easy to manage, and somewhat future-proof.

 

Multi-operator Small Cells

Middleprise businesses have traditionally avoided small cells because of their limitation to a single carrier. Installing separate small cells for each carrier looks bulky and is unappealing from a design perspective. At this year’s Mobile World Congress, Baicells introduced their NeutralCell product, a multi-operator small cell technology that promises to eliminate this obstacle.

Shared infrastructure models are gaining traction fast. Today’s mobile user expects uninterrupted coverage, no dropped calls, high bandwidth, and high data speeds. However, MNOs cannot build their networks into every single building. Since building owners often have their own ideas about how much space they want to dedicate to network equipment, NeutralCell, SUMO, and similar emerging technologies will bridge this gap so that midsize venues can improve in-building coverage for all carriers for a competitive price.

Active Passive DAS

Signal Boosters & Passive DAS

One hybrid option that many enterprises will likely opt for in 2018 is a signal booster. While most people are familiar with indoor residential signal boosters, signal boosters in a passive DAS context are new to many enterprise owners. This option works very well for building managers who are struggling with poor indoor cell service, dropped calls, or inconsistent coverage. Passive DAS is a large-scale but simple signal booster that quickly improves coverage without complicated management.

The market often uses the term “DAS” to describe an active DAS system. But a DAS is by definition a distributed antenna system, and therefore both active and passive systems qualify as true DAS. Active DAS transmits signals through fiber cables and can boost and amplify signals as needed. Passive DAS transmits uses a leaky feeder communication system consisting of a coaxial cable that functions like an antenna, with “leaks” all along the length of the cable to allow radio signals to enter the cable along its length.

Since passive DAS costs about six times less than an active DAS system, many smaller enterprises choose it over the top-of-the-line solutions. In addition to the lower price, many enterprises prefer the shorter installation time of passive DAS (1 to 2 weeks). An active DAS can take 6 to 18 months to design and install.

 

5G and IoT-Friendly Network Design

The long-awaited 5G network infrastructure is starting to be switched on in parts of Europe, with America soon to follow. While the carriers themselves will be handling the physical wireless infrastructure 5G, many owners of large and midsize venues are considering timing their upgrades to coincide with new network technology and faster speeds.

Additionally, the number of IoT devices has ballooned to almost 9 billion devices worldwide, and is expected to hit between 10 and 15 billion devices by the end of 2018. The IoT landscape is a very strong incentive for building owners to consider DAS systems. Just 15 years ago, the vast majority of office equipment consisted of hard-linked computers, but today’s workplace depends on BYOD, consumer smart devices of all kinds, and IoT/M2M business equipment. This extra traffic puts pressure on the network. Additionally, middleprise building owners have a huge range of IoT devices customized to make their lives easier: smart utility meters, IoT-based security, smart traffic sensors, and more. The cost savings of smart building technology alone is sometimes big enough to offset the cost of a DAS or small cell solution.

 

Future Outlook

The most interesting aspect of the industry space outlook is the shifting relationship between enterprise customers and MNOs. It used to be that enterprise customers were completely dependent on the MNO to build network infrastructure to improve their connectivity and capacity. This model is still true for the individual cell phone user. But enterprise customers are experiencing such heavy demand pressure that they are no longer waiting around for the MNOs to expand the network equipment to meet their needs.

NB-IoT vs. LoRa: It’s an Ecosystem, Not a Race

July 13, 2017 by Lacey Walters


As the number of connected devices rises, new technology standards have developed to handle the growing IoT space. While smartphones use cellular networks for their data, many IoT devices (for example, a smart water meter) only need to transfer small amounts of data. Relying totally on cellular or satellite networks would be expensive and use too much battery power for most devices. Similarly, WiFi and Bluetooth networks are not always a good or cost-effective solution. Most IoT devices don’t need to be in constant contact with a cellular network, so a new type of network was needed. Enter the LPWAN.

iot smart connected cityLPWAN stands for Low-Power Wide Area Network, a wireless network designed to efficiently connect smart devices across long distances, usually through a low bit rate. LPWANs are ideal for IoT devices that don’t need to manage large amounts of data, or for circumventing more expensive gateway technology. This can include smart meters, consumer products, and sensors. The overall value of the LPWAN market is expected to reach $25 billion within 4 years.

Many technology articles compare LoRA and NB-IoT technologies as if they were battling it out for dominance in the IoT market. In reality, these technologies are two branches within an emerging technology ecosystem. Similar to WiFi and Bluetooth, they will most likely to diverge into different niches, rather than directly compete with each other. This article will dive deeper into the capabilities, costs, longevity, maturity, and other differentiators of NB-IoT and LoRa-based technology.

 

What are LoRa and NB-IoT?

LoRa and NB-IoT both operate within LPWAN technology. They are two major standards for low-power IoT devices.

The LoRa Alliance developed LoRa in 2015 as a secure, energy-efficient IoT standard that makes it easy to onboard new devices. LoRa is shorthand for Long-Range (WAN) and is a modulation technology for LoRaWAN. LoRaWAN is a related set of low-power specifications for IoT devices. LoRa and LoRaWAN are not interchangeable terms; LoRaWAN refers to a LPWAN protocol standard and is not a technology in and of itself. LoRa defines the physical layer. Its security standards emphasize end-to-end encryption, data authentication, and intelligent key derivation.

NB-IoT is an abbreviation for Narrow Band IoT, a cellular standard developed by 3GPP. NB-IoT is not a standalone technology, but a cellular standard that aims to standardize IoT devices to be interoperable and more reliable. It can be implemented in a standalone or in-band spectrum manner and does not require gateways, while each LoRa device needs a gateway to function (which can affect total cost). NB-IoT connects base stations directly with sensors.

 

Key Differences

Both LoRa and NB-IoT standards were developed to improve security, power efficiency, and interoperability for IoT devices. Each features bidirectional communication (meaning the network can send data to the IoT device, and the IoT device can send data back), and both are designed to scale well, from a few devices to millions of devices.

Major differentiators between LoRa and NB-IoT standards:

Table of Key Differentiators - Lora vs NB-IoT

Latency

The most important differentiator of LoRa and NB-IoT is their latency. Here’s a quick refresher on network latency: networks and devices communicate with each other using data packets. But these data packets don’t always get transferred immediately, because it eats up battery power and network coverage. Latency is the time delay in transferring data after making a transfer request. A low latency device “checks in” with the network more often than a high latency device.

For instance, a smart sensor detects that a pipe has broken and needs to send an alert to the network. If this sensor is high latency, it doesn’t transfer data to the network very often, and it might be a few hours before the network receives the alert. If the sensor is low latency, the network will receive the alert much sooner.

 

Location / Density

Because LoRa devices use gateways, they work well in remote or rural areas without 4G coverage. They use unlicensed spectrum to communicate with the network. They also work well when they are in motion (for instance, on a truck, plane, or ship). This makes them well suited for supply chain and transportation applications. LoRa’s geolocation is non-GPS, so devices offer location services without heavy battery usage.

NB-IoT devices don’t need a gateway, and they rely on 4G coverage, either using spectrum within LTE, GSM spectrum, or “standalone,” which refers to unused frequency within LTE guard bands. This means that devices with NB-IoT chipsets perform better in indoor applications and dense urban areas. NB-IoT uses GPS technology for geolocation.

 

Power Usage & QoS

While NB-IoT and LoRa are both designed for low-power devices, NB-IoT’s lower latency means that it uses battery juice faster than LoRa. The trade-off is that it can guarantee a better quality of service (QoS) than LoRa due to faster response times. NB-IoT also boasts much higher data rates than LoRa.

What are optimal uses for each technology?

Depending on the needs of an application, one technology may be more suitable than another. For most applications, the biggest considerations are latency, battery life, coverage, and cost. In this capacity, NB-IoT and LoRa serve different purposes.

Depending on the industry and application needs, either LoRa or NB-IoT may be the better choice.

Smart metering:

Most meters process only modest amounts of data each day, so LoRa is best for most applications, assuming that the cost of installing a gateway is not prohibitive. NB-IoT is a good choice for applications that need more frequent communication or high data throughput.

Manufacturing:

Industrial automation takes many forms, and there is no one answer for this space. NB-IoT is a better choice for manufacturing applications that need more frequent communication and guaranteed QoS, while LoRa is a better choice for lower-cost sensors and longer battery life. Both are useful in different environments.

Retail & POS:

NB-IoT is a better choice. Retail transactions involve less predictable data and surges of customers, so the low latency of NB-IoT is not a good fit. Retailers risk losing sales (and customers) with the long latency time of LoRa applications.

Supply chain tracking:

LoRa is the clear winner for supply chain and transportation applications, because its mobile gateways perform reliably on a moving vehicle. Because shipments in transit or in storage don’t need to transfer much data, LoRa’s higher latency, lower data rates, and longer battery life all make sense. LoRa is also better suited for coverage in rural warehouse areas.

Smart city/buildings:

LoRa is the better choice for most smart buildings, due to easier placement of gateways. However, buildings have their own electricity supplies and therefore have less of a need for LoRa’s battery efficiency, so NB-IoT may be a better option for smart buildings with very high data throughput or a need for very low latency, such as high-security facilities. NB-IoT is also likely better for smart city networks that connect dozens or hundreds of buildings, whereas LoRa is better for a single-building application.

Agriculture:

Spotty cellular network coverage in rural areas makes LoRa the obvious choice, since LoRa doesn’t require 4G. LoRa works particularly well to track agricultural indicators, such as water usage, soil pH, and temperature gauges, which don’t shift rapidly or need immediate responses. Not only that, LoRa’s lower price point is a top selling point for farmers.

How mature is the technology?

LoRa had an early two-year lead, and highly integrated LoRa modules are already available on the market for a competitive price, with more options already in development. LoRa is already considered the IoT network industry standard for several countries, including the United States. NB-IoT options are new but are already gaining traction in industry spaces that aren’t a good fit for LoRa. The technology as a whole is expected to mature quickly due to the enormous market demand.

What about Sigfox?

Sigfox is a connectivity company whose LPWAN technology compares closely with technologies within LoRa and NB-IoT standards. Their ultra-narrowband technology uses ISM (industrial, scientific, medical) radio band. While Sigfox is growing in the space, it has not yet approached the market penetration of LoRa and NB-IoT. Sigfox’s claim to fame is its ability to cover large areas, including underground objects. The major drawback is its low throughput (about one third of LoRa) and much lower payload/message size (10 bytes vs. LoRa’s 50 bytes—in other words, its maximum message size is about one fifth of LoRa’s). Although Sigfox and LoRa compete more directly than LoRa and NB-IoT, Sigfox is more of a race for regional coverage, similar to the way GSM and CDMA race in the early days of cellular networks.

In the end…

In the end, there is no clear winner between NB-IoT and LoRa standardized devices. They address different needs. They are each part of a fast-growing network ecosystem that will host nearly 50 billion devices by the end of 2020.

Top IoT Industry Trends of Q1 2017

April 19, 2017 by Lacey Walters


The Internet of Things has enjoyed top buzzword status for a while now, but the technology has made steady strides away from the hype and towards a tangible, profitable reality. Here are the top trends of IoT since the start of 2017:

1. 3GPP Standardization of NB-IoT (Narrow-Band IoT) for LPWAN

NB-IoT technology took a leap forward last month when Cisco and Optus announced at Barcelona’s MWC they have completed live trials of NB-IoT technology on the Cisco Jasper platform. Most new connected devices are expected to launch on an LPWAN (Low Power Wireless Access Network) platform, especially inexpensive devices that use low levels of power and large ranges (smart umbrellas and toasters, for example).

NB-IoT is shorthand for Narrowband IoT (NB-IoT, also called LTE-M2). It is a radio technology standardization proposal developed by Huawei, Ericsson, Qualcomm, Vodafone, and other telecom heavy hitters. The Internet of Things is made up of hugely diverse smart devices—from airplanes to bracelets. To improve interoperability, NB-IoT was designed to allow many different types of devices and connectivity services to connect over cellular telecom bands—not just smartphones and tablets. Read more about NB-IoT here.

 

2. Connected Cars & Self-Driving Technology

CES 2017 was dominated by connected cars and related self-driving technology, with over 1000 exhibitors featured vehicle technologies or accessories. Tesla investors worried last year that self-driving technology would take a nosedive after one of their test drivers was killed last year in a fatal crash. However, commercial and private interest has grown by leaps and bounds. Uber got an early lead in the driverless tech race when it began testing driverless cars late last year in Phoenix, Pittsburgh, and San Francisco. Despite setbacks when a driverless car crashed in Arizona this month, the program is back on track. Google, Ford, and GM have also been testing self-driving technology in the United States.

Intel is the biggest newcomer to the driverless technology arena. In a $15 billion deal on March 14, it purchased Mobileye, an OEM for driverless vehicle sensors and cameras. Uber’s driverless vehicles use a sophisticated combination of roof-mounted LiDAR sensors and color cameras to interpret the road. Intel is expected to scale similar digital vision technology components to sell to automakers that cannot make the huge investment necessary to develop the technology in-house.

In the connected car software arena, AT&T boasts that it already connects 11 million cars on its network. Cisco’s Jasper IoT software now supports 50 vehicle brands, including Honda’s proprietary MyHonda Connected Car platform. Cisco has had many wins in the IoT arena with its Jasper platform, releasing smart solutions for fleet management, connected buildings, industrial equipment, and more. Over 9000 companies and 40 million smart devices run on Jasper’s Control Center software, with millions of devices being added every month.

 

5G Advancements

At Mobile World Congress 2017, South Korean carrier KT announced that it will have the world’s first commercially viable 5G network by 2019. While this is many years away from reality, many service providers are shifting discussions away from features to talk about standardization opportunities. Without a concerted standardization effort, 5G will likely take much longer to launch and be slower to grow once it does.

Ericsson recently launched its “5G for India” program to conduct 5G testing and ecosystem development in India. Many governments are considering their options for modernizing infrastructure to prepare for 5G, including China, the UK, and Thailand. Any country that gets an early lead in 5G availability will likely enjoy an economic leg-up over less connected countries. The challenge is that many infrastructure must be built from scratch, especially in countries with large rural areas.

 

IoT Security

Due to last October’s massive DDoS attack that used IoT device back doors to cause massive service outages, security is a top priority in the IoT space. Authentication and device-specific security are improving, but Sanjay Khatri, director of product marketing for IoT Services at Cisco, says that IoT security “takes a village.” If the network is secure but hackers can penetrate the device itself, the security chain has failed. Security is necessary at every link of the IoT value chain.

Information security is an escalation war, and providers at all levels are racing to protect IoT devices and applications against digital attacks. One of the most important IoT security measures already in use is REST-based APIs, which protects the movement of data between devices, applications, and back-end systems. Many device manufacturers are building two-step or even three-step authentication features into their devices. Instead of a single password, many connected things use biometrics (like a fingerprint) or digital certificates in addition to passwords and PINs. Beyond the device layer, cloud platforms like Cisco Jasper rout the data through VPN tunnels to prevent DDoS and similar network-wide outage attacks.

Small Cell Industry Trends & Talent Predictions

March 24, 2017 by Lacey Walters

Trend #1:  Outdoor Small Cell Growing 50% Faster than Indoor Solutions

The original purpose of small cells was to efficiently reuse spectrum as a capacity solution – not as a replacement for cell towers. However, outdoor small cell use as a coverage solution has grown significantly, both in rural areas and dense urban areas. While DAS and low-power small cells are well suited for indoor applications like office buildings and open-air venues like stadiums, high-power small cells are gaining ground in outdoor applications. Carriers have found that it is cheaper to densify and reuse spectrum rather than buy new blocks of spectrum for macrocell coverages. The major takeaway is that network providers and customers are taking a more nuanced view of coverage that includes a mix of small cell types and power levels to provide efficient, reliable coverage and a better handling of capacity.

Small cells still cannot beat the distance and power of macrocells (1 macro tower equals 10-30 small cells), but small cells are a cheap and effective way to patch coverage holes (at least for now — the maintenance and backhaul costs are still significant). Verizon is investing heavily in small cell densification in preparation for 5G and to support larger capacity demands. It has announced that it will begin commercial deployments this year.

Small cell comparison chart

Chart: Small cells include a mix of indoor/outdoor and high/low power solutions. Small cells improve network coverage and/or capacity. Wi-Fi is included for comparison, but is not considered small cell. 

 

Only two-thirds of new small cells are indoor, and the rest are deployed in outdoor environments. The United States is a hotbed for telecom innovation, but international demand is growing strongly as well. In the next two years, outdoor small cell is projected to jump 600%. By contrast, indoor/in-building solutions are projected to grow only 400%.

One important point to note: this small cell definition includes femtocells, whose cell radius is usually less than 50 feet and can service about 5 users at once. While femtocells do technically qualify as DRAN small cells, their application differs from other members of the small cell family.


Trend #2:  Wi-Fi Starts to Slip

It is surprising to think of Wi-Fi as an obsolete technology, but industry trends show that Wi-Fi may be on a downward slope. It used to be that only a lucky few had access to unlimited data plans, usually grandfathered from years past. Today, unlimited data plans have made a comeback. T-Mobile, Verizon, Sprint, and AT&T all offer unlimited data plans. Slower speeds have replaced overage charges for heavy data users.

LTE’s biggest advantage over Wi-Fi is that LTE can be taken anywhere (and Wi-Fi, which is an extension of LAN, will never be as mobile as LTE). As data usage climbs, people expect to use all of their devices everywhere, and finding a Wi-Fi hotspot becomes more of a burden. Coffee shops and public areas are less enthusiastic about footing the bill for Wi-Fi when many customers only buy a cup of coffee and use the network for hours. Wi-Fi technology is fussy and less secure than LTE. As security becomes more and more of an issue, customers are likely to demand LTE-based solutions over Wi-Fi. This trend will accelerate as expanding technology offers more options for less money.

Unlicensed and Licensed Spectrum

Unlimited data is not the only competitor to Wi-Fi. Carriers are rushing to densify networks and expand unlicensed spectrum coverage, a family that includes LTE-U, LAA, and MuLTEfire. Wi-Fi is becoming more of a niche technology than the go-to. LTE-U (deployments in the US, Korea, and India) and LAA (deployments in the EU, Japan, and others) use unlicensed spectrum aggregated with licensed spectrum as a Wi-Fi coexistence strategy. They improve the signal without interfering with Wi-Fi. MuLTEfire, by contrast, is LTE realized fully in unlicensed spectrum, and it poses the most serious threat to Wi-Fi. The technology may advance to the point where customers can install a private LTE router in their homes, just like Wi-Fi but with the added benefits of LTE. If the price is comparable to Wi-Fi coverage, this could make home Wi-Fi coverage obsolete.

All the way back to 1993, data usage has never dropped. Growth has accelerated year over year as carriers continue to throw money into network expansion, mostly on outdoor small cell technology to keep costs down and allow for future compatibility with 5G devices.

5G is projected to unseat (or at least compete strongly) with Wi-Fi, especially when it comes to connected devices. Connected devices are compatible with Wi-Fi and LTE, but 5G is specifically designed for compatibility with connected devices. This may prove to be the downfall of Wi-Fi. One opposing viewpoint is Wi-Fi is not going anywhere. As new technology emerges within LTE, Wi-Fi technology is also evolving. New Wi-Fi technologies are closer to carrier-grade — and carriers still rely heavily on their ability to offload on Wi-Fi.

Voice vs. Data Usage since 2011

One opposing viewpoint is Wi-Fi is not going anywhere. As new technology emerges within LTE, Wi-Fi technology is also evolving. New Wi-Fi technologies are closer to carrier-grade — and carriers still rely heavily on their ability to offload on Wi-Fi.

 

Trend #3: Changing Government Regulations

Many regulations are outdated, obsolete, and have no guidelines for the newest technology, including small cells. This hits hardest at the local level, where budgets are tight and laws can be slow to change. Many local municipalities do not have the resources to keep up with telecom technology that is changing at lightning speeds, let alone revamp the regulations.

Carriers are expecting the FCC to streamline municipal telecom regulations this year to ease the administrative and financial burden of installing small cells, towers, and other network infrastructure. Currently, many cities classify small cells the same as macrocell towers, even though the two technologies have totally different footprints, sizes, and expense. A tower can be hundreds of feet tall, while a small cell can be the size of a lunchbox. However, some cities charge the same fees for both. Some companies have attempted to classify their solutions as public utilities to save themselves hefty permit costs and administrative roadblocks.

Despite some difficulties, there are success stories. The city of Orlando, FL recently accepted bids for a large-scale small cell installation to improve coverage in the city. Some municipalities, especially in tech-friendly large urban areas, are moving ahead with ambitious small cell projects. Laws are changing to better accommodate new technologies. The city of Philadelphia worked with AT&T and Verizon to deploy a 37-node small cell network in anticipation of Pope Francis’s visit in September 2015. The project took only 9 months from start to finish. It was able to proceed thanks to huge public demand and pressure for the city and the telecom companies to work together to achieve a mutual goal.

 

Predictions for Small Cell Talent

Network providers are facing many challenges for their projects, including a severe talent shortage. We predict the following skills will be in highest demand for 2017 and early 2018:

IoT/M2M and 5G

The distance between IoT and small cell is shrinking. As Wi-Fi dependence begins to drop, network providers will need to build more and more IoT/M2M functionality into network designs (especially as 5G comes closer to being a reality). M2M connections are expected to make up almost half of all connected devices by 2020. Specifically, companies will be looking for people with hands-on experience within the IoT value chain. This includes IoT platform design, smart object design, module design, and integration with 3rd party applications.

Because of spectrum limitations, 5G will deploy on a very high frequency, including mmW. This means that traditional cell towers cannot deploy that spectrum, even with advanced beam-forming techniques. Small cells are the only way to deploy the mmW spectrum. This means carriers will have to deploy small cells—possibly on the order of millions—within the next 10 years. Since small cells have design, maintenance, and repair needs just like macrocells, there will be a huge uptick in field work, engineering, construction, and related job duties.

This is one of the biggest looming talent shortages. The IoT/M2M/5G space will create millions of jobs — some estimate over 4 million IoT developer jobs alone by 2020. However, experts also expect that IoT and connected device technology will severely disrupt the labor market. Millions of people who work low-level jobs in fast food, retail, transportation, and supply chain will be displaced.

Standardization & Infrastructure Sharing

Infrastructure sharing is a growing trend while the telecom landscape continues to shift rapidly. There will be a very high demand for employees who can understand and build strategy around shared infrastructure. This will be especially true in the next five years as networks complete coverage expansion projects.

European markets had another record year in 2016 for colocation data center capacity. Colocation promotes standardization and harmony between carriers’ data/voice technology, which is good for the consumer and the industry. Demand will continue to increase for employees with a sound understanding of existing 3GPP standards, as well as foresight for how standards may evolve to accommodate emerging technology.

Interference Mitigation Skills

In an increasingly crowded network, interference is one of the top challenges for high-traffic networks. Managing interference and higher spectrum utilization techniques will be a key goal for network providers, integrators, colocation facilities, and product developers, with applications at almost every level. Demand for this skill will rise fastest among design engineers and product managers. Expect strong demand for sales engineers who can explain interference mitigation technology to potential customers.

Public Sector Technical Sales Skills

While private sector companies are scrambling to upgrade their networks, the public sector is more uneven in its acceptance of new telecom technology. With the challenge of previously mentioned regulatory hurdles, telecom firms need to arm themselves with persuasive and highly knowledgeable salespeople. A strong salesperson can effectively navigate administrative roadblocks and match municipal requirements with network solutions that work. By contrast, some public sector entities are way ahead, aggressively updating building and fire codes with new wireless standards. Companies who win key installation deals early on are more likely to enjoy repeat business and maintenance contracts from the same customers.

Talent War in Emerging Tech: 5G, Small Cell, Connected Tech, IoT/M2M

September 6, 2016 by Lacey Walters

The emerging tech space is changing fast. Between 30 and 50 billion new IoT devices will be online by 2020. The emerging 5G network will boast a 1000x capacity increase and compatibility with new applications such as M2M, VR, AR, and connected things. Small cells and other related technologies are rapidly finding new niches. In the past six months, the technology talent surplus in these fields has flipped upside-down into “negative unemployment.”

Indeed.com reported a sharp increase in IoT-related jobs listed within the past 18 months.

 

New technologies are always on the rise: connected things, connected cities, connected cars, etc. To win the war, you need a connected recruiter. Consider this quote from The Art of War, the famous military strategy treatise written nearly 2500 years ago by Chinese general Sun Tzu:

“If you know the enemy and know yourself, you need
not fear the result of a hundred battles. If you know
yourself but not the enemy, for every victory gained
you will also suffer a defeat. If you know neither the
enemy nor yourself, you will succumb in every battle.”

                                                 — Sun Tzu, “The Art of War”

 

Any company trying to hire qualified talent is in a war with the competition. In a war, good strategy is critical to success; victory does not happen by accident. The most important factor that tech companies do not consider is what their competition (the enemy) offers:

  • Compensation packages

  • Benefits and perks

  • Training, certifications and education

  • Tools and resources

  • Environment and flexibility

  • Career growth and visibility

 

Are you fully aware of what you and your company offer?

Top candidates have their pick of companies. We conduct a company analysis with each hiring manager, including selling points for the job, what their competitors are offering top candidates, and how to structure a truly competitive overall offering to win the war.

Hiring is never easy, and the difficulties are compounded in a space with a huge skills gap and a short supply of talented workers. When you work with Blue Signal, you partner with recruiters who have deep industry knowledge providing a competitive edge. Never fear the result of a hundred battles (hires).
