AT&T has secured support from the Federal Communications Commission for authority to deploy 4G LTE service within a 20MHz portion of the 2.3GHz WCS band after cutting a deal with a next door neighbor especially sensitive about potential interference.

WCS spectrum holders have fought for years to develop commercially viable wireless service, but faced regular opposition from the satellite radio industry concerned that interference problems would result from using the band for mobile data. Right in the middle of the WCS band is Sirius XM, which depends on sensitive receivers to pick up the company’s satellite signal.

But now AT&T and Sirius XM have worked out a compromise both companies believe will protect mobile data and satellite radio. AT&T has conceded 10MHz of its total WCS spectrum for two 5MHz guard bands, devoid of signals, around Sirius XM’s frequencies. Sirius XM signal engineers believe this, combined with power limits, will protect radio receivers from overloading whenever near AT&T’s ground-based LTE cell towers.

In August, AT&T announced its intention to acquire WCS spectrum from NextWave Wireless, a spectrum-squatting holding company, for $600 million. The phone company is also attempting to acquire the remainder of WCS spectrum from the last two significant holders — Comcast and Horizon Wi-Com, which both have between 10-25MHz of spectrum in 149 and 132 communities respectively.

When the acquisitions are complete, AT&T will have WCS spectrum covering virtually the entire nation.

AT&T says it needs the spectrum to further deploy 4G LTE data service across the country. But the company admits it will take up to five years before it can switch on the new frequencies — no current smartphones support the 2.3GHz WCS band.

AT&T has also included provisions to ensure fixed wireless base stations will be able to utilize AT&T’s WCS spectrum, within reasonable limits to protect Sirius XM radios from harmful interference. That has important implications for AT&T’s long-term view that rural landline and broadband service is best delivered over a wireless network.

A major limitation of spectrum in the 2GHz band is the quality of indoor coverage it can deliver. As many Clearwire customers can attest, these frequencies suffer from high transmission loss, poor ability for diffraction, and most importantly, poor building penetration — especially in urban and suburban areas. Tall nearby buildings, homes, and even trees all impede WCS reception. According to Andrea Goldsmith in her book Wireless Communications, there is also a 6dB penetration loss when 2.5GHz signals cross un-insulated glass windows and a 13dB loss for concrete walls, with wood falling somewhere in-between.

But rural areas do better, in part thanks to the higher likelihood of unimpeded line-of-sight access between a cell tower and receiver. AT&T’s fixed wireless solution would place a small antenna on the roof or side of a home, positioned for maximum reception from the nearest cell tower. The signal is then brought indoors through cabling (or in some cases Wi-Fi) and available to customers, comparable to a home broadband connection.

AT&T’s strong spectrum position in WCS gives the company an opportunity to construct a robust, near-nationwide wireless network suitable for rural wireless communications. In more urban areas, WCS could operate seamlessly with AT&T’s lower frequency holdings and offer an extension of its current LTE service.

AT&T’s acquisition of WCS has several important implications for the wireless marketplace:

2GHz signals travel the least distance in urban and suburban areas, often blocked or degraded by buildings or trees. But better results in rural areas suggest AT&T’s WCS spectrum could partly be deployed as a fixed wireless broadband solution, if enough towers are available to support it. (Courtesy: Greenpacket)

1. It proves AT&T never needed to acquire T-Mobile USA. Through spectrum acquisitions like WCS, AT&T can still find relatively inexpensive spectrum suitable for mobile broadband use, without spending tens of billions to acquire a competitor just to poach its spectrum and eliminate a competitor.

2. The Competitive Carriers Association worries AT&T’s acquisition of secondary spectrum holders is allowing the company to gather a massive amount of spectrum.

CCA President & CEO Steven K. Berry said, “Allowing the largest carriers to obtain unlimited amounts of  spectrum on the secondary market raises serious competitive concerns.  The only way for the FCC to truly see the devastating consequences of further spectrum aggregation is by consolidating the proposed applications.  On their own, AT&T’s proposed license acquisitions may not seem significant, but when added together, it totals to a significant amount of spectrum.”

Berry continued, “Should the FCC decide to approve the transactions, it must impose conditions to ensure interoperability across the Lower 700 MHz band and to ensure data roaming – both are absolutely essential ingredients to a healthy, competitive marketplace.  Competitive carriers need access to usable spectrum, and I urge the Commission to carefully review the negative impact these transactions will have on the wireless marketplace.”

3. Clearwire’s 2.5GHz spectrum could become more valuable if AT&T can demonstrate its 2.3GHz service can deliver robust service, if provisioned adequately for customers. Clearwire’s capital investments and overall performance of its limited coverage WiMAX network have been deemed inadequate by its biggest partner Sprint, now constructing its own 4G LTE network to replace Clearwire’s WiMAX network.

4. Credit Suisse analyst Jonathan Chaplin notes Verizon will still have a better standing in spectrum even with AT&T WCS: “AT&T will have the following available for LTE: 20 MHz of 700 MHz nationwide; 20 MHz of WCS nationwide; a few AWS licenses (5 MHz on average). With Verizon’s deal with large cable companies, Verizon will have: 20 MHz of 700 MHz nationwide; 20 MHz of AWS nationwide; another 10 MHz of AWS in 60 percent of the country (13 MHz on average). In addition, Verizon’s spectrum is usable immediately, while AT&T’s WCS will take three to five years to deploy.”

Free Press’ campaign against AT&T’s Net Neutrality violation (click image for further information)

When AT&T customers take delivery of their new iPhone 5 or install Apple’s latest iOS 6 software update, the popular video conferencing app FaceTime will become available to the company’s mobile broadband customers for the first time, if they agree to switch their service to one of AT&T’s new, often more-costly “Mobile Share” plans.

Until now, FaceTime has been limited to Wi-Fi use only, but objections from wireless carriers and some technical limitations kept the popular app from working over 3G or 4G wireless networks.

AT&T’s decision to block the FaceTime app unless a customer changes their current mobile plan has sparked a notification from three public interest groups that they intend to file a formal Net Neutrality complaint against AT&T.

“AT&T’s decision to block FaceTime unless a customer pays for voice and text minutes she doesn’t need is a clear violation of the FCC’s Open Internet rules,” said Free Press policy director Matt Wood. “It’s particularly outrageous that AT&T is requiring this for iPad users, given that this device isn’t even capable of making voice calls. AT&T’s actions are incredibly harmful to all of its customers, including the deaf, immigrant families and others with relatives overseas, who depend on mobile video apps to communicate with friends and family.”

Free Press is joined in the forthcoming complaint by Public Knowledge and the New America Foundation’s Open Technology Institute.

“AT&T’s decision to block mobile FaceTime on many data plans is a direct contradiction of the Commission’s Open Internet rules for mobile providers,” said Sarah Morris, policy counsel for the New America Foundation’s Open Technology Institute. “For those rules to actually protect consumers and allow them to choose the services they use, the Commission must act quickly in reviewing complaints before it.”

AT&T earlier responded claiming they still allow the app to work over Wi-Fi (yours or theirs), so it cannot be a Net Neutrality violation. The company has spent an increasing amount of energy trying to convince regulators that wireless networks, including Wi-Fi, are largely equivalent. So long as a customer can access an app on one of them, there is no violation according to AT&T.

The company also claimed that since FaceTime comes pre-installed on phones, it is exempted from Net Neutrality regulations.

Whether the FCC will believe arguments that access over Wi-Fi is suitable enough to escape scrutiny for blocking an app on AT&T’s own 3G and 4G networks is open to debate.

The Obama Administration’s FCC has taken a lukewarm approach on Net Neutrality, adopting a compromise that is being attacked in court by MetroPCS and Verizon Wireless and considered insufficient protection by most consumer groups.

The FCC’s UHF TV Diet Plan: Slimming Down the Free TV Dial to Make Room for Expensive Wireless Broadband

By the end of this month, the Federal Communications Commission will vote on proposed rules governing a planned 2014 auction that will allow over the air TV stations to surrender their “free TV” channels in return for money from the nation’s wireless phone companies looking for more mobile broadband spectrum.

The Commission is considering reallocating UHF TV channels 31-51 for mobile data, compacting the nation’s over the air TV stations onto VHF channels 2-13 and UHF channels 14-30. But the FCC also expects many stations, particularly smaller independent or specialty channels in large cities, will be happier surrendering their broadcast TV licenses in return for cash compensation.

If the five FCC commissioners approve the plan, it will be the largest spectrum auction since 2008, and could earn the U.S. treasury billions, tempered by payouts to television stations agreeing to shut down their transmitters, and to compensate remaining stations for the cost of moving operations to a new channel number, when necessary.

“To ensure ongoing innovation in mobile broadband, we must pursue several strategies vigorously: freeing up more spectrum for both licensed use and for unlicensed services like Wi-Fi; driving faster speeds, greater capacity, and ubiquitous mobile Internet coverage; and taking additional steps to ensure that our invisible infrastructure for mobile innovation can meet the needs of the 21st century,” the agency’s chairman, Julius Genachowski, said in a statement.

The controversial auction would compensate broadcasters even before the FCC knows exactly how much spectrum it will eventually have available to auction to wireless carriers. Nobody is sure how many stations will ultimately choose to abandon their over-the-air audiences, but an FCC report predicts the largest number of station losses would be in large metropolitan areas, which often have more than a dozen stations devoted to infomercials/home shopping, ethnic shows, religious programming, and independent network affiliates. The FCC suspects some of these lower-rated stations will see the money as a strong incentive to surrender their broadcast licenses.

Genachowski

The FCC considered several spectrum-saving proposals that would free up as much channel space as possible to resell to wireless operators. One proposal would have full power broadcast outlets switch to low-powered cellular-style transmitter networks to reduce the potential interference on an increasingly crowded dial. But that proved unpopular and expensive for broadcasters. Instead, the FCC predicts stations could effectively share channels and still retain HD service. For example, a local CBS station could agree to surrender its license and broadcast instead over the transmitting facilities of the local NBC station, splitting one station’s allocated channel bandwidth in half. Other stations will be relocated on the dial or moved to different transmitter sites to reduce potential interference from stations in nearby cities.

Stations that do not require an HD service could share space with those serving several standard definition channels to the public. These are typically public, educational, or ethnic-oriented broadcasters.

As a consequence, the FCC says many stations might have to give up on their “multicast” standard definition secondary services — the 24 hour local weather or news channel, Me-TV, This TV, Retro TV, Antenna TV, and Bounce, for example, because there would be insufficient bandwidth when two services sharing one channel are transmitting in HD.

The FCC does not believe stations would mind too much, quoting from RBR/TVBR:

“So far, nobody’s been able to figure out what can go on a digital side channel and pay for its own presence there. Mostly it’s been used as a revenue-neutral or money-losing place to put 24-hour weather… Nobody watches these things in strong enough numbers to generate any advertising revenue.”

But the FCC did recognize that certain viewers in fringe reception zones could experience a loss of service — one that could be addressed by subsidizing improved antennas for homeowners or requiring cable or satellite operators to develop a “lifeline” television service consisting of local broadcasters, either for free or at a minimal monthly cost.

Some consumer groups worry that any forthcoming spectrum auction would be dominated by Verizon Wireless and AT&T — the nation’s two largest carriers, who could easily outbid smaller cell phone companies also clamoring for spectrum. During the last auction in 2008, which netted nearly $20 billion, Verizon Wireless walked away with the bulk of the spectrum on offer. Without auction rules setting aside significant spectrum for smaller competitors, both dominant carriers could lock up one of the last spectrum auctions for the next 5-10 years, cementing their de facto duopoly.

The FCC is considering reworking its market concentration rules before the bidding begins, which could constrain Verizon and AT&T from bidding and winning the bulk of available frequencies in the cities where they dominate.

New Yorkers know the end of summer is upon us when the New York State Fair opens every year at the end of August in centrally-located Syracuse. But at this year’s fair, Time Warner Cable has also made it clear the season for its 4G mobile broadband service has also come to at least a temporary end.

Fierce Cable’s Steve Donohue noticed big changes at the cable company exhibit:

When I attended the New York State Fair outside of Syracuse last year, the Intelligo mobile hotspot–which Time Warner Cable offered to subscribers through a partnership with Clearwire –was one of the hottest pieces of technology that it had on display. Time Warner Cable said that it tripled the number of 4G wireless hotspots that it sold at the fair in 2011 compared to 2010. Here in Central New York, where subscribers don’t have access to the Wi-Fi networks that Time Warner Cable, Comcast and Cablevision offer in the New York area, apparently there was a significant demand for mobile hotspots.

‘Intelligone’

This year, the mobile broadband technology is all gone. Both Time Warner Cable and Comcast are no longer selling access to Clearwire’s 4G WiMAX service marketed under each cable company’s brand. Once it became clear they were partnering up with Verizon Wireless to sell each other’s products, the days of Clearwire were numbered.

Both cable companies are still supporting existing Clearwire mobile broadband customers, but for how long nobody is certain. Verizon Wireless’ products have not yet appeared on the western or central New York regional Time Warner Cable websites, but may be forthcoming soon.

Meanwhile, Time Warner’s push this year is on home automation and security. The company has been test marketing its IntelligentHome service in Rochester for quite awhile and has now expanded to other upstate areas. The service offers a respectable suite of traditional security products apps ranging from watching your pets over webcams to controlling your home’s heating and cooling system from remote locations.

In 2010, Time Warner Cable featured celebrity Mike O’Malley at the Fair to shake hands and sign autographs. This year, they have a player and “spokesmodel” from the Syracuse Crunch, a minor league pro hockey team. Time Warner Cable also hired a juggler on a unicycle to attract crowds to their pavilion.

Stuck with snail slow DSL, spotty Wi-Fi, or usage-capped 3G and need faster access? A new project from Connectify is now attracting funding from the Kickstarter project to deliver a new broadband connection combiner that can turn up to 10 different wireless and wired connections into one super-sized broadband pipe.

Connectify’s Dispatch software will manage connections ranging from dialup to Ethernet through a hotspot application that can be run on a desktop PC. The Philadelphia company has been pushing the project primarily to the speed obsessed, demonstrating outdoor connections to multiple open Wi-Fi networks, 3G and 4G mobile broadband that when combined deliver more than 80Mbps of download speed. But the software may also prove useful as a connections management tool that can seamlessly switch from free Wi-Fi when your connection becomes intolerably slow to a different pipe — 3G or 4G wireless broadband — all without missing a beat.

With two weeks left in the Kickstarter campaign, Connectify has raised just over $33,000 of the $50,000 goal. The company recently sweetened the deal early investors get, perhaps to attract an additional burst of funding. Those investing $50 or more will receive a lifetime license with unlimited software upgrades forever.

Some mobile carriers are experimenting with similar technology, mostly to move customers automatically off of their mobile networks to Wi-Fi, where available. Others are experimenting with technology that would allow simultaneous connections to Wi-Fi and 4G networks, moving different types of data across one or both simultaneously.
