The head of T-Mobile USA claims a merged T-Mobile and Sprint will be the best positioned to quickly deliver 5G wireless service to Americans, despite claims from industry insiders Legere’s claim is little more than vaporware.

“Only the new T-Mobile will have the network and spectrum capacity to quickly create a broad and deep 5G network in the first few years of the 5G innovation cycle, the years that will determine if American firms lead or follow in the 5G digital economy,” T-Mobile CEO John Legere claimed during the April 29th merger announcement.

But the 5G network Legere is referring to is little better than T-Mobile’s existing 4G LTE network, and won’t be capable of delivering gigabit speeds or an in-home broadband replacement.

Broadband expert Dave Burstein characterizes T-Mobile’s audacious 5G claims as part of a campaign to “bamboozle D.C.” to win merger approval.

It turns out T-Mobile is not talking about the same 5G technology under development at AT&T and Verizon, which both use millimeter wave networks and small cell antennas.

T-Mobile’s version of 5G is a already appearing elsewhere around the world — a new definition incremental upgrade for 4G LTE, “70-90 percent slower than the good stuff — millimeter wave,” claims Burstein.

“Folks building LTE-speed networks wanted to be called ‘5G’ and take advantage of the massive hype,” Burstein wrote. “So they made ‘New Definition 5G’ with a PR campaign and a minor software tweak, dubbed ‘NR’ for New Radio. 4G LTE networks [suddenly] became ‘5G.’ Every engineer in the business knows this is a scam.”

T-Mobile’s version of ‘5G’ is likely to appear on its spectrum in the 600 MHz range, easily deployed from existing cell towers and relatively cheap and easy to launch. It won’t deliver anything close to the speed or capacity improvements being claimed by Legere and a few others in the industry.

“Legere is swearing to Washington the T-Mobile 640 MHz 5G NR network will be many times faster than LTE,” Burstein said. “That isn’t true, of course. It’s far more likely to be only 25%-50% faster, or perhaps less. It may even be slower than the 500 MHz LTE/LAA T-Mobile already has in Manhattan.”

China claims to be ahead of the United States — another issue being pushed by T-Mobile merger supporters to “regain” America’s “lead” on 5G — by deploying its own version of 5G similar to the ‘new definition’ version of 5G Burstein talks about. The Trump Administration has even contemplated nationalizing America’s 5G network infrastructure to share benefits among all leading wireless carriers, if only to speed deployment and generate new demand for network equipment produced in the United States — not China.

But a closer look at China Mobile’s version of 5G finds the company installing approximately two million “mid-band” 5G cellular antennas that will work at 3.7 GHz. It isn’t the millimeter wave 5G technology contemplated by AT&T and Verizon, and won’t deliver much faster speeds than China Mobile’s existing 4G LTE infrastructure. Instead, it will help China Mobile better manage its bandwidth demand with a network at least twice as large as that of AT&T or Verizon.

Critics of ‘new definition 5G’ call the technology “evolutionary, not revolutionary.”

What makes millimeter wave 5G technology superior is the wide swath of dedicated spectrum typically available for wireless broadband. Some companies will have 400 to 800 MHz of frequencies available to support millimeter wave 5G, while the maximum spectrum for LTE is around 100 MHz. That extra millimeter wave spectrum has delivered up to 20 Gbps speeds in the lab, and Verizon is contemplating selling gigabit speed service to its fixed wireless customers using the technology sometime this year.

Despite Legere’s boastful claims, Burstein warns politicians and regulators they need to learn that T-Mobile’s type of “5G” is no longer “a big thing in most cases.” Even seasoned regulators like Jessica Rosenworcel and Ajit Pai at the FCC have incorrectly confused new definition 5G with millimeter wave 5G. Others, including Andrus Ansip at the EU and several Chinese leaders, have made similar mistakes as part of boastful claims about future network performance.

Burstein says it is a case of not listening to network engineers, who know the difference.

“They have engineers at the FCC,” Burstein said. “If they listen to the engineers, they will know the [merger] deal is not in the public interest.”

Bad results for Frontier DSL in Nevada. (Source: Elko Residential Broadband Survey)

Only six Frontier Communications customers surveyed in Elko, Nev. gave the phone company an “A” for its DSL service, while 42% flunked Frontier for what they considered unacceptable internet service.

The Elko Broadband Action Team has surveyed residential and business customers about broadband performance and found widespread dissatisfaction with Frontier Communications over slow connections and service interruptions.

“I’m pretty disappointed in them,” said Elko councilman John Patrick Rice.

Businesses and residential customers were in close agreement with each other rating Frontier’s service, with nearly 87% complaining they endure buffering delays or slowdowns, especially when watching streaming video. When browsing web pages, nearly three-quarters of surveyed customers still found service lacking.

Among the complaints (Res)-Residential (Bus)-Business:

• Service interruptions: 74.43% (Res)/79.69% (Bus)
• Too slow/not receiving advertised speed: 72.16% (Res)/65.75% (Bus)
• Price: 63.64% (Res)/37.5% (Bus)
• Customer Service: 38.07% (Res)/45.31% (Bus)

The Nevada Attorney General’s Bureau of Consumer Protection received a steady stream of complaints about Frontier’s DSL service in the state over the past year.

Answering the survey question, “would you be interested in faster download and upload speeds at prices that are somewhat comparable to what you are paying now?” 97.87 percent of residential respondents said yes.

Frontier representatives responded to the survey results at a March 27 Elko City Council meeting.

“Frontier did recognize it could improve upstream and downstream flow and educated the council and the public on some of the issues,” Elko assistant city manager Scott Wilkinson said.

The Federal Communications Commission is pushing hard to free up additional spectrum in some unlikely extremely high frequency ranges — some at 95 GHz or higher, for the next generation of wireless services.

Just a year ago in 2017, the FCC wrapped up its latest spectrum auction for the higher end of the UHF TV band, to be repurposed for mobile service use. But now the agency is seeking to find and reassign underused spectrum in much higher frequency bands that could be used for services like 5G wireless, machine-to-machine communications, intelligent road and vehicle networks, and other uses yet to be invented or envisioned.

FCC Commissioner Jessica Rosenworcel made it clear that smart spectrum allocation was critical for next generation wireless services.

“The point is the list is long — and we are looking at midband and millimeter wave to power the 5G future,” Rosenworcel said. “The propagation challenges are real, but so is the potential for capacity with network densification. Of course, what we need to do next is get these airwaves to market and unconditionally hold an auction this year.”

The FCC is contemplating auctions covering these frequencies in 2018:

3.5 GHz

Widely expected to draw the most interest, the Citizens Broadband Radio Service band was originally intended primarily for unlicensed users, but the wireless industry has lobbied heavily to get much of this spectrum reassigned for traditional long-term licensed use. Although very high frequency, the 3550-3700 MHz “innovation band” will have plenty of wide range of frequencies open for wireless data and mobile services. The wireless industry wants to deploy LTE service on this band, but they will likely compete with cable operators that are seeking their own stake of frequencies to launch their own wireless services.

This band will likely support last mile wireless connections at gigabit speed, fixed wireless broadband, and even in-home Wi-Fi that is significantly better than what you have now.

Because the band is so attractive, several different users are competing over who will be portioned what spectrum. The cable and phone companies want more for themselves, but other users, including consumers, want to reserve enough spectrum for unlicensed applications. The concern is deep pocketed companies may crowd out innovators and start-ups.

3.7 to 4.2 GHz

Some consumers may have accessed services on these frequencies without ever realizing it. This is the home of the “C-Band,” recognizable to any home satellite dishowner of the 1980s and 1990s. This range of frequencies is set aside for line-of-sight, very low powered satellite television — the kind that used to require a 10-12 foot wide satellite dish in the backyard to receive. FCC Chairman Ajit Pai wants to open the band up to be shared with 5G wireless broadband, which has caused considerable controversy among satellite users who fear devastating interference.

There are proposals and counter proposals from the satellite industry and wireless companies over how to manage sharing this band. Most are coalescing around the idea of sequestering 100 MHz of spectrum at the low-end of the band and using 3700-3800 MHz for high-speed wireless broadband. Some want satellite operators to clear out of this section of frequencies voluntarily, others propose compensation similar to what was given to television stations to relocate their channel positions. Google is pushing for a plan that would offer mobile 5G service in large urban areas and 25 Mbps – 1 Gbps fixed wireless broadband in rural and residential areas.

But satellite companies and many satellite users are fearful of the impact of interference. Because satellite signals use very low power transponders on the satellite, ground based wireless broadband interference could wipe out satellite reception.

Tom Taggart, who owns several radio stations in West Virginia, says sharing spectrum was tried before and did not work well.

“This band, years ago, was shared with AT&T and other telcos for point-to-point long-distance links. Fixed, licensed paths that could be plotted and protected against for satellite installations,” Taggart told Radio World. “Our studios are 1,500 feet from an old MCI tower, at one time we had a metal screen behind our satellite dish to protect against ‘back-scatter’ from a path aimed away from us. Still, we had to convince MCI to shut down one channel so we could pick up a program from Premiere [a radio network distributing programming on satellite].”

Some industry plans propose registering C-Band satellite dishes, at a cost of $600-$1,600 per site, which would allegedly protect them from interference by requiring wireless broadband services to steer clear of the area.

“But I am not even sure what kind of broadband services are proposed,” Taggart said. “One might assume these would be omnidirectional sites, like a typical cell site. Even with some clever computer-engineered directional patterns, reflections off hillsides, billboards, buildings would be enough to overwhelm the tiny satellite signal. However, other articles described these services as ‘mobile.’ Even if my dish is registered, how can I resolve interference problems from a mobile device?”

The debate rages on because the frequencies involved, next to the even more popular CBRS band, are highly coveted.

4.9 GHz

After the events of 9/11 in 2001, the FCC has prioritized public safety communications, in hopes of improving the interoperability of different first responders’ portable radios. At that time, fire agencies could not easily talk to police, ambulance crews, or in some cases other fire crews arriving from different departments miles away.

Many agencies contemplating use of this band discovered equipment that supported 4.9 GHz was hard to find and extremely expensive. Most public safety agencies seeking grants or other funding to improve their communications equipment opted to transition to digital P25 networks that operate on much lower frequencies and use equipment that is now widely available and, in comparison, much cheaper. Many agencies are conservative about using new technology as well, concerned a communications failure could cost the life of a fire or police responder. As a result, of the 90,000 organizations certified for licenses in this band, only 3,174 have been granted. That represents a take rate of just 3.5%. The band, as one might expect, is effectively dead in most areas, underutilized in others.

“As the demand for wireless services continues to grow, it is imperative that the FCC takes steps to ensure underutilized spectrum bands are used efficiently,” said FCC Commissioner Mignon Clyburn. “This is as true for spectrum allocated to public safety as it is for the bands used to support commercial wireless broadband services.”

FCC Commissioner Michael O’Rielly is convinced wireless companies like AT&T and Verizon could use the frequencies more efficiently.

“It has been 16 years since the 4.9 GHz band was allocated to the public safety community, and it is still woefully underutilized,” said O’Rielly. “That is not sustainable in an environment in which every megahertz of spectrum, especially below 6 GHz, needs to be fully scrutinized and maximized in quick order. While the Commission’s original allocation was more than likely well-intentioned, it is way past time to take a fresh look at this 50 megahertz of spectrum.”

Although higher than 3.5 GHz, engineers believe there is a very credible case to be made to use the available spectrum for 5G fixed wireless services, delivering broadband at speeds up to 1 GHz from a small cell located nearby. It would have to be. At these frequencies, virtually anything blocking the line-of-sight between the antenna and the user will block the signal as well. With almost no constituency defending the 4.9 GHz turf, it is expected it will be repurposed for wireless broadband in areas where it isn’t in use for public safety communications.

24/28 GHz

Although the 28 GHz band has many licensed users already, the 24 GHz band does not, and the wireless industry is interested in grabbing vast swaths of spectrum in this band for 5G home broadband. Known as “millimeter wave spectrum,” these two bands are expected to be a big part of the 5G fixed wireless services being planned by some carriers. Verizon acquired Straight Path late in 2017, which had collected a large number of licenses for this frequency range. Today, Verizon holds almost 30% of all currently licensed millimeter wave spectrum, an untenable situation if you are AT&T, T-Mobile, or Sprint. T-Mobile has been the most aggressive seeking more spectrum to compete with Verizon in this frequency range, and has purchased almost 1,150 MHz covering Ohio for use with a 5G project the company is working on.

39 GHz

FiberTower, now owned by AT&T

This band might as well be called “the controversial band” because AT&T made moves on these frequencies even before the FCC got around to discussing an auction for this band, likely also to be used for 5G fixed wireless. FiberTower originally held hundreds of licenses for wireless spectrum for several years, but did little with them, leading to suggestions the company was either hoarding the spectrum to resell to someone else or was incapable of deploying a network that used the frequencies. The company declared bankruptcy in 2012, eventually emerging in the spring of 2014 just in time to watch the FCC uphold the decision of its Telecommunications Bureau to cancel 689 of FiberTower’s licenses for failure to use them.

In February 2018, AT&T completed its acquisition of FiberTower for $207 million. According to AllNet Insights & Analytics, AT&T acquired more than 475 of FiberTower’s 39 GHz spectrum licenses, raising eyebrows among shareholders who lost their investments in FiberTower after it declared bankruptcy. Hundreds of the spectrum licenses that came with the AT&T deal were given a value of $0.00, allowing AT&T a sweetheart deal and shareholders hoping to recover more money from the bankruptcy liquidation extremely upset. In fact, had FiberTower remained in bankruptcy, it would eventually have surrendered all of its licenses, which would then be put up for auction by the FCC and would likely command much higher value among bidders. Verizon effectively paid triple the price for what AT&T got for a song in the FiberTower acquisition. Even more remarkable, the FCC approved the acquisition by AT&T despite the obvious fire sale price, and has ignored the consequences of what could come from an AT&T/Verizon duopoly across large swaths of 5G frequencies.

Eshoo

That brought a rebuke from Rep. Anna Eshoo (D-Calif.) who accused both Verizon and AT&T of flipping public property for private gain.

“The FCC’s policies unambiguously required Straight Path and FiberTower to forfeit their unbuilt spectrum licenses,” Eshoo wrote. “But rather than auction the reclaimed spectrum and promote timely deployment, the FCC’s Wireless Telecommunications Bureau reached ‘resolutions’ with Straight Path and FiberTower than allowed them to profit handsomely from their wrongdoing. Following the ‘resolution,’ Straight Path sold its assets to Verizon for nearly $3.1 billion, and FiberTower is estimated to have sold its assets to AT&T for roughly $2 billion.”

In reality, AT&T acquired FiberTower for $207 million — a fraction of the amount of the estimated value of the spectrum Eshoo used in her estimate.

“The Bureau’s decisions also further concentrated critical input resources in the hands of the two dominant wireless incumbents,” Eshoo continued. “The purchasers of the public assets that Straight Path and FiberTower once held, Verizon and AT&T, already control a disproportionate amount of other critical spectrum available for immediate deployment. Up until recently, the industry had an imbalance in favor of these companies in low-band spectrum that lasted for decades. The FCC now risks going down the same wrong path with high-band spectrum should the Commission continue down this course. Allowing Straight Path and FiberTower to ‘flip’ public assets for private gain does nothing for taxpayers, but does much to further entrench the dominant incumbents’ longstanding spectrum advantage over their rivals.”

95+ GHz

The FCC has not regulated frequencies above 95 GHz, but as technology advances, there is growing interest in utilizing spectrum that many believed would be essentially unusable for communications services. Right now, most frequencies in this range are used by environmental satellites and radio astronomy. At these frequencies, signals would be absorbed by the skin and attenuated significantly by things like high humidity’s haze or fog. Still, there are proposals under consideration to open up a small portion of spectrum for unlicensed home users for things like indoor wireless routers.

The key policy priority here will be to protect existing users from any hint of interference. But with vast amounts of unused frequencies in this range, it shouldn’t be difficult to keep competing users apart.

AT&T is rolling out mobile 5G service for its wireless smartphone and tablet customers in a dozen U.S. cities by year’s end, starting in parts of Atlanta, Ga., and portions of Dallas and Waco, Tex.

“After significantly contributing to the first phase of 5G standards, conducting multi-city trials, and literally transforming our network for the future, we’re planning to be the first carrier to deliver standards-based mobile 5G – and do it much sooner than most people thought possible,” said Igal Elbaz, senior vice president, wireless network architecture and design. “Our mobile 5G firsts will put our customers in the middle of it all.”

AT&T’s mobile 5G will work differently from the fixed wireless home broadband service Verizon is launching this year using small small cell neighborhood antennas. But like Verizon, AT&T is taking a gradual, incremental approach to the next generation of wireless technology.

In 2017, AT&T announced what it calls “5G Evolution” service in almost two dozen cities, although this branding was derided as “fake 5G” in the tech press because, in reality, it is just an improvement of today’s widely deployed 4G LTE service. Similar technology is also in place at T-Mobile. In the fall of 2017, AT&T introduced 4G LTE-Licensed Assisted Access (LTE-LAA) technology in Indianapolis and parts of Chicago, Los Angeles and San Francisco. This network lays the foundation to offer gigabit speed wireless service, and is especially useful in areas where AT&T’s spectrum holdings are tight.

AT&T’s initial 5G rollout will serve parts of:
A – Atlanta, Ga.
B – Waco, Tex.
C – Dallas, Tex.

AT&T is preparing its existing wireless network to permit gradual migration to the completed 5G wireless standard over both existing and new spectrum.

This year, AT&T plans to launch some 5G service using millimeter wave spectrum, which is very line-of-sight and offers a more limited service area. But the technology will support very fast wireless speeds and offer plenty of bandwidth. AT&T could deploy this technology initially in dense population areas and places like stadiums, malls, and convention centers.

“Ultimately, we expect to reach theoretical peak speeds of multiple gigabits per second on devices through mobile 5G,” AT&T wrote in a press release. “While speed is important, we also expect to see much lower latency rates. With higher speeds and lower latency rates, our mobile 5G network will eventually unlock a number of new, exciting experiences for our customers.”

If past precedent means anything, AT&T will likely only initially offer 5G service in selected parts of each city. It needn’t hurry, because equipment designed to work with the new spectrum isn’t expected to become widely available until 2019. A gradual transition will also please shareholders by keeping network upgrade costs predictable over the next 3-5 years.

AT&T isn’t expected to use 5G technology anytime soon as part of its taxpayer-funded, rural wireless broadband deployment. AT&T currently uses its 4G LTE technology to power its fixed wireless rural broadband service. AT&T claims this service was designed to assure download speeds of at least 10 Mbps, although customers using it report speeds are often lower, although sometimes higher. AT&T does not offer and network performance guarantees, stating, “service performance may be affected by your proximity to a cell site, the capacity of the cell site, the number of other users connected to the same cell site, the surrounding terrain, radio frequency interference, applicable network management practices, and the applications you use.” That will also be true of AT&T’s forthcoming 5G network.

Residents of a handful of multi-dwelling apartments and condos in Boston, Washington, and Los Angeles will be able to kick the phone and cable company out of their units and switch to a fixed wireless provider offering 200 Mbps internet access for $50 a month.

Starry Wireless, from the man who brought you Aereo, the now defunct streaming service that used to offer local over the air stations but was sued out of existence, has spent more than a year testing its millimeter wave wireless technology in Cambridge, Mass. apartment buildings and is ready to expand.

A company promotional video explains Starry’s internet service. (1:53)

Starry is considered a startup, but is relying on budget-conscious pre-existing technology to deliver point-to-multipoint wireless internet service over a limited area. Using pre-standard 5G technology that relies on unlicensed millimeter wave spectrum, Starry’s service is provided from antennas mounted on multi-story buildings.

Because the technology isn’t revolutionary, Starry can utilize equipment already for sale in the marketplace. Some commercial fixed-wireless services already exist using a similar approach, and Google itself is developing a wireless gigabit internet service that is likely to eventually overtake its limited fiber rollouts.

Starry currently offers one plan – 200/200 Mbps with no data caps or contracts for $50 a month. The company claims it can deliver gigabit service using the same technology, but has chosen not to offer it at this time.

Reviews in the Boston area give the service high marks for performance, even in bad weather that was expected to create some problems for the line-of-sight technology. But the service also has its skeptics who believe the technology’s downsides limit its scale.

The biggest con to millimeter wave internet is that its range is extremely limited. Starry is only expected to serve multi-dwelling units in dense urban areas, where its mounted rooftop antennas can reach enough customers to cover the company’s costs. Neither Google or Starry have targeted their services to residential customers living in single home neighborhoods. Starry also must find receptive landlords willing to offer or lease space for its antenna equipment and tolerate mounted equipment, as needed.

Starry’s technology approach offers a concentrated signal with extensive bandwidth available to customers. Because its reach is so limited, each antenna will reach a smaller number of customers, making it unlikely the company will oversell its wireless capacity. Starry’s decision to not get into the gigabit business yet may be a way of ensuring it has enough capacity to deliver the speeds it advertises to customers before speeding things up.

Customers are strongly encouraged by the company to use its included Starry Station, a triangular Wi-Fi hub with a built-in Android-powered touchscreen controller to manage in-home Wi-Fi. This device normally retails for around $300, so bundling it with internet service makes it a good deal. But the device gets mixed reviews. Some criticized it as over-engineered and unstable. Many reviewers complained about poor Wi-Fi coverage and randomly dropped wireless signals. Others complained it tends to lock up, which may be the result of overheating. Many noticed the unit generates a lot of heat, presumably from its built-in power supply and Android touchscreen interface. It requires a noticeably loud built-in fan, which runs continuously, to manage cooling duty.

The Starry Station did not get great reviews for its performance or the amazing amount of heat it generates. (2 minutes)

Despite the expansion into Los Angeles and Washington, Starry can still be considered a beta level service and availability will remain spotty for some time. During 2018, Starry expects to begin limited service in: New York, Cleveland, Chicago, Houston, Dallas, Denver, Seattle, Detroit, Atlanta, Indianapolis, San Francisco, Philadelphia, Miami and Minneapolis.
