Kingsbury Commitment - Wikipedia
"The Kingsbury Commitment of 1913 was an out-of-court settlement of the government's antitrust challenge of AT&T's growing vertical monopoly over the phone industry. In return for the government's agreement not to pursue its case against AT&T as a monopolist, AT&T agreed to divest the controlling interest it had acquired in the Western Union telegraph company, and to allow non-competing independent telephone companies to interconnect with the AT&T long-distance network."

"In 1956, AT&T and the Justice Department agreed on a consent decree to end an antitrust suit brought against AT&T in 1949. Under the decree, AT&T restricted its activities to those related to running the national telephone system, and special projects for the federal government. "

"In 1982, AT&T and the Justice Department agreed on tentative terms for settlement of antitrust suit filed against AT&T in 1974, under which AT&T divested itself of its local telephone operations"

AT&T’s “5G E” is actually slower than Verizon and T-Mobile 4G, study finds | Ars Technica
AT&T's "5G E" service is slightly slower than Verizon's and T-Mobile's advanced 4G LTE networks, a study by OpenSignal has found.

"AT&T's network name change may well trick consumers into thinking they're getting better service than a 4G operator, but they aren't. We already knew that 5G E has no technological advantage over LTE-Advanced, because they are the same thing with different names. But actual speed tests could reinforce that point."

Big Telecom Sold Highly Sensitive Customer GPS Data Typically Used for 911 Calls - Motherboard Feb 2019
"Around 250 bounty hunters and related businesses had access to AT&T, T-Mobile, and Sprint customer location data, according to documents obtained by Motherboard. The documents also show that telecom companies sold data intended to be used by 911 operators and first responders to data aggregators, who sold it to bounty hunters. The data was in some cases so accurate that a user could be tracked to specific spots inside a building."

"Some of the data available to CerCareOne customers included a phone’s “assisted GPS” or A-GPS data, ... A-GPS is a technology that is used by first responders to locate 911 callers in emergency situations."

Will 5G live up to the hype? It depends who you ask | PolicyTracker: Feb 2019
Verizon CEO Hans Vestberg, for example, told the CES show in Las Vegas that “5G will change everything”. “We’re going to see a technology change that is going to transform people, businesses and society,” he said.

At the same tech convention, AT&T CEO John Donovan confirmed that the mobile carrier would switch the “LTE” indicator to “5G E” (for evolution) when users connect to the operator’s faster LTE network.

The International Telecommunications Union (ITU) also recently published a report that highlights spectrum management issues, infrastructure sharing, access costs and investment incentives as key issues to consider for 5G success.
“A viable case for investment in 5G can be made for densely populated urban areas… [but] rural and suburban areas are less likely to enjoy 5G investment, and this will potentially widen the digital divide,” it says.

It has also warned regulators against premature 5G deployments. “The need for 5G is not immediate,” notes the report.

"AT&T, Verizon gear up for 5G network slicing in 2020, 2021 | FierceWireless Jan 2019"
At its most basic, network slicing provides for a more efficient use of the network. Instead of allocating on a serialized basis, operators can do things in parallel by allocating network resources and applying certain quality of service (QoS) elements to them. Services could be priced based on the quality or performance that a business needs; even a traditional MVNO could be structured based on slice agreements.

With network slicing and 5G, the idea is for operators’ business customers to get connectivity and data processing tailored to their specific requirements—latency and/or speed, for example. The GSMA estimates (PDF) that in combination with other enablers and capabilities, network slicing will permit operators to address a revenue opportunity worth $300 billion by 2025.

T-Mobile, Sprint, and AT&T Are Selling Customers' Real-Time Location Data, And It's Falling Into the Wrong Hands, Motherboard Jan 2019
"T-Mobile, Sprint, and AT&T are selling access to their customers’ location data, and that data is ending up in the hands of bounty hunters and others not authorized to possess it, letting them track most phones in the country."

"The bounty hunter did this all without deploying a hacking tool or having any previous knowledge of the phone’s whereabouts. Instead, the tracking tool relies on real-time location data sold to bounty hunters that ultimately originated from the telcos themselves, including T-Mobile, AT&T, and Sprint, a Motherboard investigation has found. These surveillance capabilities are sometimes sold through word-of-mouth networks."

"at least one company, called Microbilt, is selling phone geolocation services with little oversight to a spread of different private industries, ranging from car salesmen and property managers to bail bondsmen and bounty hunters"

AT&T strikes deal with Toyota, walks the line on C-V2X / DSRC debate, Jan 2019
"AT&T has slipped out a minor announcement about LTE connectivity on latest-model Toyota and Lexus cars and trucks in the US, starting from the fall, just as the technology and automotive markets appeared in a newly climactic embrace ahead of the 2019 Consumer Electronics Show (CES) in Last Vegas this week."

"But near-term car connectivity is a sideshow this week, as autonomous driving comes into clearer view at CES. Amid the bluster, the declaration from Ford that cellular vehicle-to-everything (C-V2X) is the only way to go for driverless cars was notable."

"Competitor brands, meanwhile, including AT&T’s latest LTE-partner Toyota and Ford’s country rival General Motors, are backing Dedicated Short Range Communications (DSRC) technology instead, in what the New York Times has described as the automotive sector’s VHS/Betamax moment."

AT&T will not launch any more satellites for DirecTV, Analysys Mason Dec 2018
"AT&T will not launch any more satellites for DirecTV: is the writing on the wall for satellite TV?"

"AT&T’s acquisition was motivated by an appetite for DirecTV’s content rights (notably for National Football League (NFL) American football matches) as much as its subscriber base, but the recent announcement indicates just how quickly the US pay-TV market is evolving."

"One of the reasons why the move to OTT is so rapid in the USA is that traditional pay-TV bundles are expensive. "

"What does this mean for satellite TV providers? Analysys Mason agrees that IP-delivered TV and video services will eventually dominate the market, but it will be a long time before direct-to-home satellite services disappear entirely. "

Satellite companies propose C-band sharing plan with US mobile operators | PolicyTracker: Feb 2018
“Asked whether moving out of the band will give satellite operators a monetary windfall, [SES chief strategy and development officer] De Hauwer declined to speculate about the size or precise use of any such compensation. However, he said, satellite service providers in space and on the ground have invested billions in the C-band over the decades, and any change to that ecosystem is complex and expensive.”

“If the satellite companies don’t do anything, the FCC might allocate the spectrum under less favourable terms and without any compensation, said Telecom, Media and Finance Associates satellite consultant Tim Farrar. The possibility of receiving billions of dollars for moving out of the band is attractive because the satellite industry isn’t a rapidly growing one and a windfall would be welcome, he said.”

“If the FCC goes along with the SES/Intelsat plan, controversy could flare around who ends up with the 100 MHz of satellite spectrum, Farrar said. He noted in a blog post that wireless operators Verizon, AT&T and T-Mobile put forward divergent views on reallocation mechanisms in comments to the regulator’s consultation on expanding flexible use in mid-band spectrum between 3.7 GHz and 24 GHz. Verizon called for a near-term notice of proposed rulemaking (NPRM) with market-based clearance mechanisms rather than an auction. AT&T asked for “substantial record development, including additional analysis and modeling” before the launch of an NPRM, while T-Mobile said the agency should reject the Intelsat proposal and auction the spectrum.”

SiriusXM-AT&T Want Approval for Interference Fix. | Story | insideradio.com - Feb 2017
It has been a decade since SiriusXM Radio first raised the issue of AT&T cellphones causing interference to its network of land-based repeaters. In a letter to the Federal Communications Commission, SiriusXM VP James Blitz says the two companies have devoted “significant resources” toward a “joint coordination effort” to resolve the interference issues. They’ve included what Blitz describes as “extensive and frequent communication at multiple levels of each company” as well as “thousands of hours” of equipment testing. It seems to be paying off.

T-Mobile presses for mmWave auction in 2018, says major carriers already acquiring significant holdings | FierceWireless, Jan 2018
If it wasn’t clear before, it is now: Wireless operators want to get their hands on more millimeter wave spectrum, and the more, the merrier. And smaller carriers are worried the deck is going to get stacked against them in favor of the largest operators.

Those themes continue to emerge through comments filed with the FCC as part of its Spectrum Frontiers initiative. The FCC has asked for input on how it should structure spectrum bands above 24 GHz for mobile radio services, and carriers aren’t shy about responding. AT&T, Verizon and T-Mobile, plus the industry association CTIA, are pushing for an auction in 2018, with T-Mobile in particular pointing to Verizon’s accumulation of millimeter wave spectrum on the secondary market giving it a competitive edge.

AT&T makes case for 5G spectrum auction based on financial voucher system | FierceWireless
"Keeping up with its argument that the FCC needs to get moving on 5G spectrum auctions, AT&T is proposing an auction of millimeter wave spectrum that’s based on a voucher system that it says puts incumbent licensees and other potential bidders on a level playing field.

AT&T notes that one of the challenges to a millimeter wave auction, especially in the 39 GHz band, is that incumbent licensees have holdings scattered throughout the band, typically in 50 MHz chunks."

T-Mobile launched commercial LTE-U networks across six cities in February. Furthermore, in June T-Mobile trialed LAA achieving 741 Mbps downlink, and plans to deploy it this year. Also in June, AT&T reported hitting 750 Mbps in its LTE-LAA trial, with its own plans for commercial launch by end of 2017. In the month of August, Verizon announced it is in the process of rolling out a commercial LTE-LAA network. The company also reported reaching 953 Mbps downlink speed in a recent trial. Outside of the U.S. (but in June as well), MTS of Russia has been trialing LTE-LAA. For these, and other operators, LTE using unlicensed spectrum helps get them to 1 Gbps LTE.

Editor's Corner—Telecom’s move to software and virtualization hounded by the same old problems | FierceWireless May 2017
"For years, carriers and vendors have been touting the wonders of software-defined networking (SDN) and network functions virtualization (NFV). These technologies, the argument goes, will enable network operators to replace expensive, proprietary hardware with software-powered, virtualized services running on cheap, off-the-shelf hardware. The result, vendors and carriers have said, will be an industry that can pivot on a dime, quickly developing and launching new, powerful, revenue-generating services while cutting costs in the process. The result, however, is not quite that. At least not yet."

Level 3 "is reluctant to go much further down that path due to concerns that what the company develops might not interoperate with services from other vendors or carriers"

"AT&T, an early mover in the SDN and NVF space, has said it expects that fully 55% of its network operations will be virtualized by the end of this year. . . . But still, AT&T doesn’t yet have any concrete cost savings it can point to from its virtualized, software-powered migration."

Verizon "said that the operator’s decision to standardize much of its software efforts on OpenStack “is a challenge right now.” "

"But standardization efforts in this area are still in their early phases, and expenses are mounting."

"It’s no surprise that the telecom industry is calling for more interoperability in its migration to SDN and NFV. After all, interoperability is one of the few key tenets underpinning the growth of the global telecommunications industry—communications only work when everyone speaks the same language."

With that in mind, engineers at AT&T (NYSE:T) Labs set out to identify radio-frequency propagation models that will help pinpoint optimal small cell placements. The result of this research is AT&T's proprietary HetNet Analysis and Resource Planning (HARP) tool, which analyzes key data points to help network planners understand how RF waves behave in a small cell environment. Based upon a location's traffic demands, along with building floor plans or topography maps, HARP can determine expected coverage for both indoor and outdoor small cells and recommend the optimal number and placement of small cells."

Bulbs Behind Bars II: FCC Goes After Hair Salon Lighting Fixture : CommLawBlog: "Light bulb"
The salon’s fluorescent lights emitted a stray radio signal at 705 MHz, part of a band licensed to AT&T for the delivery of 4G service to smartphones and tablets. This particular frequency is used for transmissions from a mobile device to a cell tower, such as the cell tower that rises up directly behind the Perfect Cuts Salon.

Fon brings its shared Wi-Fi model to the U.S. - FierceWirelessTech
Madrid-based Fon, which encourages users to share their Wi-Fi router signal with others in exchange for free access to other Fon hotspots around the world, jumped into the U.S. market with a new router that accepts Facebook (NASDAQ:FB) credentials in lieu of a password. Fon's upgraded $59 Fonera router combines its usual Wi-Fi sharing features with new functionality that uses Facebook Connect in place of Wi-Fi passwords, which can be challenging both to remember and enter Fon also upgraded the Fonera router to act as a signal booster. That is because many people in the United States already have their own Wi-Fi routers, but they could use help extending signals to dead spots in their houses. Last month, AT&T and Fon signed a global Wi-Fi roaming agreement ... In addition, Fon has a partnership with T-Mobile US parent Deutsche Telekom in Germany as well as Sprint parent Softbank

Bandwidth breakdown: Mobile rates could rise - Features - Al Jazeera English = Feb 2012
Standard bandwidth crisis narrative I think there will be a major crunch in the next few years," Kang Shin, professor of computer science at the University of Michigan, told Al Jazeera. "The number of these mobile services and applications is mind boggling and the smart phone user population is growing … The wireless spectrum doesn’t just grow on trees." "AT&T's mobile data traffic, for example, grew 8,000 per cent in the past four years, industry sources told Al Jazeera, and by 2015 they expect mobile data traffic to be eight to ten times higher than it was in 2010." "Milton Mueller, a professor of information studies at Syracuse University and a founder of the Internet Governance Project, thinks new technologies will solve most of the problems."

NAB to FCC: Interference threatens auction success | Regulation content from Broadcast Engineering
"Failure to conduct engineering studies of potential co- and adjacent-channel interference stemming from a repack of TV spectrum and the repurposing of different amounts of spectrum in different markets — known as spectrum “variability” — threatens to derail FCC efforts to free up TV spectrum for the wireless industry and maximize auction proceeds. Those are among most important conclusions of reply comments filed June 28 by NAB with the Federal Communications Commission."

AT&T's numbers show carriers' public Wi-Fi networks may not be justifiable - FierceBroadbandWireless
"Smartphone users rely on Wi-Fi for their primary data connection, but they rarely turn to managed, public hotspots, favoring instead private or unmanaged, self-provisioned public Wi-Fi hotspots, according to mobile analytics vendor Mobidia Technology and analyst firm Informa. The findings were based on data collected in January 2013 from an anonymous sampling of millions of users who have downloaded Mobidia's smartphone application, My Data Manager."

US LTE operators achieve 4G success by focusing on coverage and multi-device strategies - Insight - News | Analysys Mason Jan 2013
"US operators initially marketed LTE by highlighting its speed benefits, and kept the same pricing plans as 3G services in order to entice users onto the new networks, including customers on flat-rate plans. AT&T and Verizon have both shifted their pricing strategies in order to increase revenue. Initially, both operators largely eliminated flat-rate pricing plans in favour of tiered pricing, and in 2012 both operators implemented a multi-device, tiered data package pricing strategy. Operators are still adopting the strategy of 'no premium for LTE', with the only difference between a 3G subscription plan and an LTE plan being the device used. Instead of charging more for the LTE service, operators want to connect additional devices for a nominal fee (usually USD10–30) to encourage users to switch to larger data plans. This strategy appears to be working"

AT&T under fire for exempting microcell traffic from U-Verse data caps | Ars Technica
Public Knowledge is raising the alarm about AT&T's decision to exempt traffic generated by AT&T's wireless microcells from the data caps imposed on U-Verse broadband customers. PK's Michael Weinberg says that AT&T is "egregiously abusing data caps to give its own services advantages over competitors." A microcell is like a miniature cell phone tower that a user attaches to a home broadband connection to improve wireless reception. Like other mobile providers, AT&T offers microcells that improve wireless reception by routing phone traffic over the customer's home Internet connection. If a customer acquires a microcell from Sprint or Verizon and connects it to the AT&T U-Verse broadband connection in her home, any traffic generated by the device will count against the data caps that AT&T imposes on U-Verse customers.

Level 3 protests Verizon, AT&T "lock-up" data connection deals
"Since the FCC doesn't require the big telco and cable ISPs to lease out their lines at wholesale prices, CLECs like Level 3 buy voice/data interconnection from the incumbents at their "special access" rates. For over a decade, the regulation of these prices has been a source of huge regulatory combat—pitting Verizon and AT&T against smaller carriers Sprint, T-Mobile, Clearwire, and cbeyond, all of which belong to the No Chokepoints Coalition."

Cisco leads charge towards integrated Wi-Fi/cellular - Rethink Wireless Mar 2012
Cisco "leapt into a flood of small cell announcements [at Mobile World Congress] with the first carrier gateway to implement the Next Generation Hotspot (NGH) standards, which automate authentication, security and roaming across cellular and Wi-Fi networks.., Alvarion, which gained a carrier Wi-Fi play with the acquisition of Wavion, also said its latest systems are enabled for HotSpot 2.0."
"Small base stations with integrated Wi-Fi have been one of the major features of this year's event. Ericsson, hard on the heels of acquiring carrier Wi-Fi firm BelAir, has also announced a pico base station supporting 64 cellular or WLan users. Other launches have come from the Wi-Fi community (Ruckus Wireless), the femtocell space (ip.access and Ubiquisys), and all the big five traditional base station vendors. Alcatel-Lucent added Wi-Fi management - and later integrated base stations - to its lightRadio platform while Nokia Siemens unveiled FlexiZone as a step towards HetNet."

Small wireless carriers: always stuck with crappy phones?
Discussion of band classes in 700 MHz, and the claim that AT&T is forcing manufacturers to build only devices for the lower B and C block. Claim by Good Faith Purchasers Alliance: "one of the largest carriers is believed to be issuing Requests for Proposals ('RFPs') that specify only equipment capable of operating only over Lower Band 700MHz Blocks B and C; and the other of the largest carriers is believed to be issuing RFPs specifying only Band Class 13, i.e., Upper Band 700MHz Block C. As a result, consumers and smaller carriers that acquired Lower Band 700MHz Block A spectrum are left without viable and widely useful equipment options."

We've written about it enough times not to be surprised by the practice anymore, but the Center for Public Integrity has just concluded an in-depth investigation of the practice that's well worth a look. In order to support its proposed T-Mobile buyout, AT&T has dug deep into its roster of supporters, going so far as to get local groups like the Shreveport-Bossier Rescue Mission to write letters of support to the federal government.
