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.

A preview of the possible aesthetics battle of future 5G small cells that are expected to proliferate across America’s cities and towns in the coming years is taking place in Santa Rosa, Calif., where residents and some city officials reacted with surprise when Verizon began attaching “small cell” wireless repeater equipment on 72 city-owned light and utility-owned poles around the city. While not exactly the same at the 5G equipment Verizon is preparing to install in Sacramento to launch its forthcoming fixed wireless service, the similar-sized equipment turned out to look nothing like what was promised by Verizon officials. But city officials learned this only after the project was approved by a 7-0 City Council vote in 2017.

In January, one resident learned about the sudden arrival of Verizon Wireless’ equipment when she opened her front door one morning to confront a utility pole decorated with antenna equipment and a 5-foot high utility box about 30 feet away from her home.

“I’m planning to put this house on the market and the mechanisms on the telephone pole and in the ground are very aggressive and ominous-looking,” said Judith Monroy, 75. “You can’t miss them.”

Within days, someone vandalized the utility box, spray painting the word “no” and “stop this” for all to see.

In many areas, 5G small cells will be installed on utility or light poles in the front yards of residential homes. Wireless companies will want to place equipment on poles that are not obstructed by foliage or tall, nearby infrastructure, which can block signals. Requests for aggressive tree trimming to remove obstacles, within the limits permitted by local ordinances and the policies of the pole owner, are also likely. This is certain to create controversy if property owners find their trees or shrubbery removed or aggressively pruned. But for many others, the appearance of the new equipment is enough to provoke protests.

When some property owners discovered Verizon was also adorning electric utility poles with its cellular equipment, some started referring to them as “PG&E’s Godzilla Poles.”

The utility poles hosting Verizon’s equipment have new “branches” attached several feet below pre-existing utility wiring, onto which small cell antennas are attached.

As more equipment gets installed, the more concerned citizens are phoning up city hall to complain.

Last week, city officials bowed to citizen pressure and temporarily suspended Verizon Wireless’ antenna upgrade program. While some residents cited health and safety fears from electromagnetic radiation — a fear repeatedly debunked — many more were upset by the aesthetics of the equipment and wondered if the city got a raw deal.

“I think it is time to push the pause button on this installation in our neighborhoods,” said John Cushman, a resident of Hidden Valley. “This project has been rushed and the only urgency I can see is financial.”

Verizon is paying the city $350 per pole, an amount some local residents consider absurdly low. As opposition mounted, some uncomfortable members of City Council that originally voted in favor of Verizon’s plan changed their minds, according to The Press Democrat:

“I am supportive of putting the brakes on this,” Councilman Tom Schwedhelm said. “I’m not convinced that we’ve done everything that we can so we can look anyone in the face and say ‘Yes it’s safe there. It’s safe to be in front of my house.’ ”

Councilman Jack Tibbetts said he viewed the rollout as a “commercial enterprise” that perhaps was better suited to commercial areas given the city’s stated goal of helping strengthen the city’s wireless infrastructure to foster entrepreneurialism.

“I’d like to see residential zones be carved out in our ordinance,” Tibbetts said to loud applause in a chamber full of people wearing bright yellow stickers reading “Caution: Cell tower microwave frequency hazard.”

But Verizon may have positioned itself to move forward regardless of what the city has in mind.

The company announced it would continue installation at 25 previously approved sites where it already has permits in-hand. Verizon has yet to obtain permits to place equipment at two other PG&E sites and 31 city light poles.

The city will not have much say over pole attachments on PG&E’s infrastructure, which is governed on the state level by the California Public Utilities Commission.

If the city denies Verizon’s request to install its equipment on city-owned light poles, the company could just move those antennas to other PG&E poles nearby instead.

Verizon has announced a wave of call center closures in several states that will results in layoffs, although some employees will be invited to reapply for their position if they are willing to move to another state or continue their work as a “Home Based Agent” taking customer service calls from a home office.

Verizon is cutting back on customer service call centers, after looking for ways to cut expenses and direct customers to use “self-service” options on Verizon’s website. For those who still want to speak to ‘a real person,’ increased hold times may be the result. Verizon maintains 16 call centers around the country, with at least six scheduled to close and a seventh closure already in progress.

Affected customer service call centers:

• Mankato, Minn. — Originally a call center for Midwest Wireless and Alltel before being acquired by Verizon Wireless, about half of the estimated 600 workers will be invited to continue as Home Based Agents, while others will be laid off or invited to apply for another position if they are within 90 miles of another Verizon call center and are willing to commute or relocate. Just a few years ago, this call center was desperate to hire new workers, handing out lucrative signing bonuses and other incentives. The center is expected to close by this September.
• North Charleston, S.C. — Formerly a Montgomery Ward department store, Verizon Wireless repurposed the 150,000 square foot facility and hired up to 1,000 workers when it opened in 2004. About 500 workers are being invited to transition into Home Based Agents, “supporting customers the same way and with similar tools as if they were working from a traditional brick-and-mortar call center,” according to a Verizon spokesperson. Verizon will save almost $2 million a year in rent closing the call center. The layoffs and call center shutdown are expected to be complete by September.
• Huntsville, Ala. — The call center in Research Park will be shuttered “in the coming months,” with workers invited to participate in the Home Based Agents program. Verizon claims it will cover “most” of the equipment and supplies needed to work from home, and will pay a stipend of $65 a month for internet access. But other ongoing home office-related expenses, including electricity, furniture, insurance, and other related costs will the employee’s responsibility.
• Albuquerque, N.M. — Verizon Wireless will shut down its 197,000 square foot call center by October 2019, with workers selected for its Home Based Agents program transitioned out of the building by May of 2019. At least 1,000 workers are likely affected. The call center cost $30 million to open in 2006 and by 2009 employed 1,600 workers.
• Hilliard, Ohio — A Verizon call center that formerly absorbed a lot of displaced Verizon call center employees across the region is itself shutting down by November of this year. Qualified workers are invited to continue as Home Based Agents. Verizon employees complain Home Based Agents lack job security and are usually among the first to be laid off in any future downsizing actions. Some recommend relocating to another call center instead of working from home.
• Little Rock, Ark. — Verizon has informed its 600 Little Rock call center employees they are shutting down the office by this October, and workers that want to stay with Verizon will be able to transition to a work-at-home model or apply for a job elsewhere in the company.
• Franklin, Tenn. — Already downsizing, this call center will be shuttered sometime this year, with workers invited to apply for the Home Based Agents program. But some workers with experience working from home warn there are significant downsides: “You can’t relocate to another call center or move to the Home Based Agents program if you are on ‘corrective action’ (for attendance or performance),” said one worker. Those employees will lose their jobs and receive severance packages. “Moral of the story, don’t let yourself get an attendance warning for your kids having the flu [thinking] ‘I will [accept a write-up]’ because if your center closes, you cannot relocate.”

Verizon spokesperson Jenny Weaver told the Albuquerque Journal a very different story about home agents.

“At other places, we’ve found it’s a satisfaction driver for employees,” Weaver said. “Happy employees translates to happy customers, so we’re excited about this.”

AT&T is staying committed to its wireline network in the face of two significant natural disasters by replacing beyond-repair copper wiring with fiber optics.

The phone company has recently notified the Federal Communications Commission its existing facilities in parts of California that were damaged by last year’s wildfires will be replaced by fiber optic infrastructure.

Fierce Telecom notes customers affected by the Nuns, Tubbs, Redwood and Sulphur fires will be served by a new optical fiber network in portions of Sonoma, Ukiah, Santa Rosa, and Lower Lake.

“The circuits will be transferred to fiber based NGDLC systems,” AT&T said in a FCC filing. “The transfer of these circuits does not compromise the capacity of the cabinets.”

In Florida, as a result of last September’s Hurricane Irma, AT&T will migrate its irreparably damaged copper wire network that strings throughout the Florida Keys to a new fiber to the home network.

AT&T’s decision to maintain its wired networks comes in contrast to Verizon’s 2013 attempt to scrap its copper facilities on Fire Island, N.Y. and certain New Jersey barrier islands left devastated by Superstorm Sandy. Verizon hoped to replace traditional landline service with a wireless alternative known as VoiceLink. A firestorm of protests over the service’s limitations, sound quality, and reliability forced Verizon to scrap the plan in New York and install its FiOS fiber-to-the-home network instead.
