Cornell University uses an NSF grant for a low-budget system to bring Internet connectivity to cities, towns, and villages.

The expense of fighting Covid-19 and state coffers depleted by business restrictions and outright closures has made countless new networking projects a bridge too far for blue and red states alike.

But amid the global pandemic, Cornell University in New York has secured a $!.5 million grant from the National Science Foundation (NSF) to design and build a statewide IoT network. It will bridge the digital divide and set the stage for new and more efficient applications to all municipalities.

A model for state IT teams

The closely watched public IoT project will likely result in the first statewide IoT network in the U.S., making it a model for IT managers elsewhere in the country also looking to accelerate the introduction of IoT for all in the toughest of times.

Key to the innovative project is the use of the Low-Power Wide-Area Network (LPWAN) architecture that uses lower-speed WAN links to connect far-flung devices such as sensors that use long-lifetime (10+ years) batteries to power the system.

Closing the digital divide?

The public IoT network plans to bridge the digital divide that exists between New York City in the east to small communities in upstate New York along the Canadian border. And while high-speed services in big cities across the country are table stakes, broadband connections are still a tough find in rural areas, which also suffer from spotty or no cellular service.

The grant’s abstract explains that the work is motivated by an imperative need to bridge the digital divide between rural and urban areas, which it says “has contributed not only to information disparities, but also greater social, democratic, educational, and economic disparities.” The research will test the concept of IoT networks as a public utility to bridge the digital divide. “This project explicitly sees rural communities as opportunities for developing new networked technologies which can leapfrog traditional wired broadband technologies and create new opportunities for local technological development and innovation.”

Getting started

In August, Cornell engineers and researchers landed the NSF grant. They will work with community partners in each county around New York through the Cornell Cooperative Extension. The entity, the CCE, has been described as a network of independent associations located in each county in the state and the boroughs of New York City. The organization teams with local communities “to translate research into practical projects through data-based programs and services.”

The game plan

“We aim to create a public Internet of Things model that works here and then becomes replicable for other states,” Max Zhang, a professor in Cornell’s Sibley School of Mechanical and Aerospace Engineering, told the Cornell Chronicle. "We want to provide universal network coverage, ensure data privacy, promote responsible data-sharing, scale-up successful Internet of Things implementations, and spur technology innovation in underserved areas."

The chief goal of the IoT network project is to provide all New Yorkers access to the Internet. That is because while densely populated areas, suburbs, and major transportation routes are already being fitted with wireline and wireless broadband infrastructures, rural areas still suffer from spotty access to broadband and often lack cellular service.

“You need to create a reliable internet of things infrastructure to handle a digital world,” said Max Zhang, a professor in Cornell’s Sibley School of Mechanical and Aerospace Engineering and the project’s principal investigator. “This is an opportunity for rural communities. You cannot have a digital revolution in digital darkness.”

With that in mind, the statewide IoT network should provide uniform network connectivity to a system that reaches all residents. What that is expected to do is use the LPWAN architecture to support a long potential list of IoT applications that have the following characteristics: long-range, low-power, and low-bandwidth.

The following anticipated IoT applications to be supported on the statewide net include:

  • Remote meter reading for utility firms
  • Traffic monitoring
  • Realtime road and flood monitoring
  • Crop and livestock monitoring for farmers
  • Building management

LPWAN selling points

The designers and creators of the New York statewide IoT network selected LPWAN technology for the network for several reasons.

  1. The technology is long since tried and true as a staple by entire vertical industries (oil and gas and utilities among them) to monitor and manage their pipelines and transmission facilities.
  2. LPWAN networks are anything but expensive as their core components; sensors and long-life battery-powered, attached devices are inexpensive can run for a decade without replacements.
  3. These battery-powered devices, such as sensors, transmit a small amount of data, typically to a central or regional location. This keeps bandwidth usage charges low.

Early returns

Early on, Tompkins County began providing its residents with free IoT access, according to Ken Schlather, executive director of the Tompkins branch of the CCE, who is expected to coordinate the networking project’s community engagement with each county in New York. He claimed a pilot program of IoT-enabled commercial buildings reported energy cost savings of between 15% and 30%, which he added, was similar to results from its other, larger studies.

The statewide IoT network undertaking is also an educational effort, wrote the NSF in the grant’s abstract. "This project not only creates the first introductory course in IoT at Cornell University but also expands the engaged learning opportunities to citizen across [New York State] through innovative, community-based learning hubs; a model that can be replicated across the U.S.”

After the failure to launch a market sector in the 1990s, a largely new field of players is betting big on high-speed services for a very different world.

Before the close of the 20th century, an entity called Iridium launched a network of low-earth orbit (LEO) satellites designed to provide enterprises, the military, and the government an out-of-this-world resource for communications links to virtually any location back on planet Earth.

Iridium’s constellation of satellites initially focused on telephony applications in the decade-long, pre-iPhone era. Motorola-backed Iridium survived a LEO constellation market segment shakeout that hit others, including Globalstar, Teledesic, and Odyssey.

Now fast forward to 2020, where Elon Musk's SpaceX, Amazon, Telesat, and OneWeb are vying to fully take flight to support next-gen networking-driven initiatives here on Earth, likely providing IT managers with fresh new options for supporting new and rearchitected business undertakings.

With earlier geostationary satellites, several high-orbit birds could provide global coverage, albeit from over 22,000 above Earth. With LEOs, which are set at about 100-1,200 miles above the planet, a LEO can cover about 1/66th of the globe, which means a large constellation of birds is required for true blanket global coverage. Though they have shorter lifespans, they are more advanced and less expensive.

As a result, today’s LEO satellite networks promise higher-throughput, lower-delay communications that provide more bandwidth per user, “even more than cable, copper, and pre-5G fixed wireless,” states a report released by McKinsey & Co. earlier this year.

Changing uses

Early LEOs were commonly used for voice communication and military applications. However, this latest generation of operators are expected to offer HD video streaming, higher-bandwidth data communications, and provide rural broadband to bridge the digital divide. Most of their former voice traffic is carried on terrestrial wireless and wired networks.

Musk’ SpaceX had already launched a constellation with over 400 LEO satellites by April (with more to come) under the Starlink brand name. Telesat will start with over 100 birds, with more available, and Amazon has already filed to launch 32,000 plus satellites in its constellation.

Under Amazon’s Project Kuiper, the company will invest $10 billion in an FCC-approved plan to launch 3,326 LEO satellites.

Yet another competitor is OneWeb, which has emerged from bankruptcy under new management and with new funding just before Thanksgiving. It plans to recommence satellite launches in December, toward its initial goal of 650.

Technology is allowing IT managers to address safety concerns with sensors now; smartphone chips on the way.

Faced with fighting a global pandemic that shows no signs of letting up, organizations in multiple verticals are beginning to use shirt-distance, low-power Ultra-Wideband (UWB) radio technology to power their social distancing and contact tracing operations today.

Around for years, UWB provides a highly accurate, low-power, robust, and secure wireless technology for locating a device's position, movement, and distance. The tech supports very high bandwidth communications and works over a wide range of frequencies, hence the name ultra-wideband.

UWB has experienced growing momentum in recent months, as more companies offer devices or chipsets that support the technology, according to a recent forecast from ABI Research, a global tech market advisory firm.

Supporters claim UWB is more reliable than nearfield communications (NFC), Bluetooth, and Wi-Fi-based smartphone apps for tracing. UWB is currently used with sensors initially designed for implementations in large factories. With Covid-19 gripping the masses, companies in verticals, including entertainment, chemical, construction, and food and beverage, have embraced it for contact tracing.

Taking the Field

Though established and proven, UWB has lacked a high-profile while similar options grabbed the headlines. That changed in August when the National Football League (NFL) announced that UWB would handle its contact tracing and social distancing efforts – an undertaking crucial to the league's ability to play the 2020-2021 season within the states' rules COVID-19 handling mandates.

"Each player and each staff member of each team (has been) issued wearable tags, and they will be on at all times during practice sessions, games, and times of team travel," the NFL said. The organization estimated that it would deploy up to 2,000 such sensors across the country during the season.

The NFL told the FCC is "doing everything possible to ensure that the teams, their staff, and the NFL operations personnel maintain safe distances and that, should a case of coronavirus occur, that there is contact tracing in place to be able to limit the spread of the virus."

How It Works

The NFL's system uses sensors that interact with each other and provide audible and visual alarms if people get too close for more than a few seconds. The tags can be worn on a lanyard, a clip, or on a wristband. The league added some players also had them built into equipment typically used in practice and games. The National Basketball League (NBA) also uses UWB-based contact tracing.

UWB does this by transmitting data across short distances and precisely determines location by measuring how long it takes for a radio pulse to travel between devices. The frequency range of UWB is between 3.1 and 10.6 GHz

The UWB-enabled system assesses which employees had contact with an infected person and are at the greatest risk of exposure. When it comes to pinpointing location, systems often report a 10-centimeter precision, with some reporting less than 5 centimeters.

The Cost Component

There does not appear to be much in the way of system cost(s) available to IT managers considering UWB-driven contract tracing and social distancing system. Beyond the necessary bandwidth, Kinexon, which teamed with the NFL, claims a low of 70 cents per sensor per day, which adds to the equation.

Those planning or considering implementing a UWB-based contact tracing system should first check to see if they have enough spectrum to avoid interference with other wireless applications.

The NFL did just that and determined there was a significant threat of interference with its player tracking system, which uses chips in players’ pads to gather data that results in slick graphics known to all as Next-Gen Stats.

According to a filing by the league, the league asked for and received permission from the Federal Communications Commission to use a slice of the Citizens Broadband Radio Service (CBRS) band for the 2020-2021 season.

This will allow the league to support safe operations during using low-power, body-worn wireless sensors for players and staff to promote social distancing and COVID-19 contact tracing this season.

The current players in UWB-driven contact tracing are hardly household names, but like Kinexon, they've gathering steam in the enterprise IT space. Currently, Iterate Labs, Ubisense, Piper Networks, Qorvo, and Bluecats are addressing soaring IT managers’ need for tools for contact tracing among employees in this year (and likely more) of Covid-19 as the virus has long since gone global.

CBRS Spectrum Auction Transforms Enterprise Cellular Landscape

Some might find auctions where participants hold up paddles or pull their ear lobes to bid on a cherished asset exciting. But it’s an easy bet that the real action after the Citizens Broadband Radio Service (CBRS) will come early next year when enterprises look to establish advanced wireless networks.

Utilities, universities, hospitality companies, and energy firms acted on the opportunity and bid on and, in some cases, landed licenses for CBRS use for planned private networks. And because the FCC stipulated winners must use or resell them rather than become squatters, it is safe to assume there are hard and fast plans for their use by enterprises for wireless networks.

But large users seeking spectrum for private LTE networks is a face grabber. The CBRS auction is made real a wide variety of additional enterprise cellular options – and providers - to IT managers. Among them are hybrid networks, managed service, connectivity as-a-service offerings, and turnkey networks together expected to steal the spotlight starting in early 2021.

Nobody left behind

Those enterprises that didn't bid on CBRS spectrum are anything but out of business as the haves (providers) are looking at ways to deliver wireless networks using licensed and unlicensed CBRS spectrum to provide an alluring range of wireless network options. And the winning bidders can lease out their unused space to anyone to avoid losing it, which has some expecting a secondary market or CBRS exchange accessible to the user masses.

Qualcomm claims a forthcoming unit boasts power efficiency for IT managers looking to support large-scale, long-lasting, IoT applications affordably.

A promising new chipset that portends to accelerate the creation and expansion of cellular IoT networks for new business-transforming applications/use cases appears likely to grab the attention of enterprises, entire cities, and carriers in the U.S. and abroad.

The modem chipset boasts greater power efficiency, a key element in the cost of massive, low-power, IoT networks. Wide-area nets are already known for connecting inexpensive and far-flung devices such as sensors that transmit small amounts of data.

That should be a trifecta worth tracking for IT managers and application deployment staff tasked with charting the future of their employers’ business networks. The chipset will not be commercially available to device vendors for inclusion in their equipment until the second half of this year, says Qualcomm.

Municipalities seek power to handle deployment rules and regulations, while wireless operators back an FCC order designed to streamline processes in the race to 5G.

A court case that could either break a 5G deployment logjam for carriers or slow their ability to rollout next-generation wireless services in the U.S. bears interest by enterprise IT managers across the U.S.

For nearly two years, cities and towns have initiated legal action against wireless carriers claiming the gear needed for 5G services poses financial, aesthetic, and safety concerns to their populations. And most contend a 2018 Federal Communication Commission (FCC) order designed to streamline deployments for carriers is illegal.

The crux of the ongoing situation is that dozens of municipalities have established rules, time periods, and fees associated with the permitting and installation of pizza box-sized small cell antennas required by 5G rollouts in their communities. The FCC order speeds permitting periods and reduces fees by nearly 50%.

If it hasn’t already, this dispute, portends to slow carrier deployment, and hence delay enterprise use of 5G services. Carriers continue to race toward what they term “nationwide” deployment of the super-fast 5G services, which everyone from enterprises to the FCC Commissioner and current U.S. president believe can transform businesses across industries.

"The race to 5G is on, and America must win," Trump said a year ago. "According to some estimates, the wireless industry plans to invest $275 billion in 5G networks, creating 3 million American jobs quickly, and adding $500 billion to our economy." In late March, he signed a piece of legislation, the Secure 5G and Beyond Act of 2020, which is designed to address the security of 5G networks.

Small cell challenges

The differences between 4G and 5G are faster speeds, higher bandwidth, and lower latency. Next-generation 5G services are expected to enable and justify applications such as IoT device-powered smart cities. Also identified uses include automated factories, telehealth, and eventually self-driving vehicles. These game-changing use cases, however, will require broader coverage, which means billions of dollars for new infrastructure. Battles with municipalities over implementations could be something wireless carriers can’t afford.

Unlike 4G, which required large cell towers that were not popular with many municipalities, 5G uses far smaller, pizza box-sized antennas - and lots of them.

The number of deployed small cells is expected to increase by a factor of nearly 10 in from 2018 to 2026, according to The State of Wireless – 2018, a report from the CTIA, a wireless communications industry trade association. This expected increase, the CTIA directed, “underscores the importance of every level of government modernizing its wireless infrastructure rules.”

The crux of the issue is whether the FCC can limit what cities and towns can charge carriers to set up small cells attached to their infrastructure (e.g., light poles). Under the FCC’s rule, local governments can charge providers $270 in access fees each year per cell site, roughly half of the pre-rule $500 national average.

A key issue is whether the agency can establish periods of time for the approval or denial of carriers’ applications to create the small cells. This was also part of the FCC’s 2018 ruling.

As the legal action continues, another concern for carriers rolling out 5G services is that the rules, permitting time periods, and fees are not uniform. They are piecemeal and vary from municipality to municipality, a fact that can slow service rollouts.
