AT&T’s two pronged fiber build out strategy

AT&T appears to be pursuing a two pronged strategy to build out fiber to the premises (FTTP) delivery infrastructure. The first is targeting densely built up metro areas with its Gigapower joint venture with BlackRock’s Global Infrastructure Fund. The second using subsidies extended to the states from the 2021 Infrastructure Investment and Jobs Act’s (IIJA) Broadband Equity, Access, and Deployment (BEAD) Program to build FTTP infrastructure in less densely developed areas that meet the program’s funding eligibility requirements.

Last fall, AT&T urged states to award the BEAD subsidies for contiguous builds that qualify as unserved (where at least 80 percent of serviceable addresses in the project are not offered throughput of 25/3 Mbps or better) and underserved (where at least 80 percent of serviceable addresses are not offered throughput of 100/20 Mbps or better). However, under BEAD, states must first exhaust their funding allocations on subsidies for projects addressing unserved locations.

As noted in the above linked blog post, AT&T’s BEAD funding appears predicated on the two generations of Digital Subscriber Line (DSL) technology that runs over its legacy copper voice telephone delivery infrastructure. The first, ADSL, will in many less densely developed areas qualify as unserved since it typically provides bandwidth lower than 25/3 Mbps. However, these areas are often adjacent to those served by its second generation VDSL technology. Those areas won’t qualify as unserved but could likely qualify as underserved.

Federal and state officials overseeing the award of BEAD funds will likely come under pressure from AT&T to liberally interpret the program rules to allow subsidization of contiguous FTTP projects spanning areas including both types of DSL technology. Expect AT&T to argue that this will provide the most efficient use of the funds and cover the greatest number of serviceable locations as well as meeting the BEAD program's preference for FTTP.

AT&T urges states to favor contiguous BEAD funded projects serving both unserved and underserved locations

AT&T is urging states to award subsidies of up to 75 percent of construction costs allocated by the federal government’s Broadband Equity, Access and Deployment (BEAD) program for combined projects containing both unserved (where at least 80 percent of serviceable addresses in the project are not offered throughput of 25/3 Mbps or better) and underserved (where at least 80 percent of serviceable addresses are not offered throughput of 100/20 Mbps or better).

In so doing, AT&T is clearly indicating it plans to use any BEAD funding it is awarded to edge out its footprint. Some addresses could be served by VDSL over AT&T’s existing copper cable plant and qualify as underserved under BEAD program rules. As DSL signals degrade with distance, addresses farther out from its central offices and DSLAMs would likely not and be served by first generation ADSL – or no landline connections whatsoever – falling below the 25/3 Mbps cutoff and thus qualify as unserved. Some addresses in the latter category might ostensibly be designated as extremely high cost locations that AT&T would serve with fixed wireless.

A potential problem AT&T faces at least some states in urging BEAD funding for contiguous unserved/underserved projects is BEAD program rules require states to first award funds for projects reaching unserved locations. Underserved projects can only be funded if there are enough funds remaining from a state’s BEAD allocation after all unserved locations have been served.

AT&T is apparently aware. “We know that this won’t be possible in every state," writes Erin Scarborough, president of AT&T’s Broadband and Connectivity Initiatives, in a blog post. As the “next best alternative,” Scarborough urges states to group eligible locations into the smallest geographic unit possible, such as a census block, and allow providers to combine them into project areas. “This would still enable providers to design efficient deployments that maximize the use of existing infrastructure,” Scarborough wrote.

AT&T apparently hoping for BEAD subsidies to replace DSL over copper with FTTP

AT&T is apparently hoping for BEAD subsidies to replace its legacy DSL services delivered over twisted pair copper with fiber to the premise (FTTP). States should take a flexible approach in subgranting the subsidies allocated by the National Telecommunications and Information Administration’s (NTIA) Broadband Equity, Access and Deployment (BEAD) program to afford “ISPs flexibility to identify project areas to include a mix of unserved and underserved locations will allow for the most efficient use of limited funds,” suggested Erin Scarborough, president, Broadband and Connectivity Initiatives in an April blog post. In a blog post this week, Scarborough stated that would allow providers to “identify project areas that combine unserved and underserved locations to enable the most effective and efficient deployments.” For AT&T, those would be locations served by legacy ADSL and VDSL, respectively.

That would comport with the BEAD program rules spelled out in the NTIA’s Notice of Funding Opportunity (NOFO). It permits states to subgrant up to 75 percent of construction costs to builds “constituting a single unserved or underserved broadband-serviceable location, or a grouping of broadband-serviceable locations in which not less than 80 percent of broadband-serviceable locations served by the project are unserved locations or underserved locations.” The NOFO defines “unserved” locations as those not marketed connectivity with throughput of less than 25/3 Mbps and latency exceeding 100ms. “Underserved” locations are those not offered at least 100/20 Mbps. That would encompass premises served by AT&T’s legacy DSL offerings delivered over obsolete twisted pair copper initially designed to support voice telephone service.

Whether states will have sufficient BEAD funding to subgrant subsidies for underserved locations remains to be seen after the NTIA announces state allocations next week. The BEAD NOFO requires states to award subgrants “that ensures the deployment of service to all unserved locations within the Eligible Entity’s jurisdiction.” These unserved locations are likely to be in lower density areas lacking wireline connections, requiring higher capital construction costs and subsidization.

Purpose of AT&T's 4G LTE fixed premise service to mollify pols, not modernize telecom infrastructure

Speedy internet delivery for rural DeSoto County | News | desototimes.com: Flint said as part of this commitment across 18 states, AT&T plans to reach more than 400,000 locations throughout 18 states by the end of 2017, and over 1.1 million locations by 2020. AT&T plans to reach over 130,000 locations with this technology across Mississippi by 2020. Flint said delivering broadband internet service to rural underdeserved areas has been AT&T's challenge.

According to Flint, AT&T's Fixed Wireless Internet Service delivers a home internet connection with speeds of at least 10Mbps. The connection comes from a wireless tower to a fixed antenna on customers' homes or businesses. "This is an efficient way to deliver high-quality internet to customers in rural and underserved areas," Flint said. "This will be capable of delivering a fixed wireless signal at a speed of 10 megabits per second, more than enough to do web browsing with plenty of speed and to stream your favorite movie or TV show. The telecommunications infrastructure was made possible through the FCC Connect America Fund.

The primary purpose of this rollout is to mollify politicians continually barraged with complaints from constituents about poor advanced telecommunications service options. Bolting on fixed premise service to existing 4G LTE mobile wireless towers is not a long term investment in modernizing telecommunications infrastructure. It's simply another on the cheap substitute for replacing decades-old twisted pair copper cable designed to support voice telephone service with fiber optic cable to support advanced services.

AT&T is deploying this fixed wireless service in areas where its copper cable plant cannot support digital subscriber line (DSL) service, some of which never even got first generation ADSL deployed more than a decade ago. AT&T's fixed premise wireless service will offer throughput that does not conform to U.S. Federal Communication Commission standards for delivering high quality high-quality voice, data, graphics and video. That shortcoming will be amplified in peak use periods given multiple connected devices used in households and small businesses and the fact that wireless bandwidth is by definition limited and connectivity slows as more users access it.

Another sign of the coming end of AT&T's U-Verse

In late September, this blog predicted AT&T will abandon its Project Lightspeed/U-Verse deployment sometime in the first half of 2010 as part of a general retreat from the wireline-based residential/home office market segment.

Another sign of the coming end of the U-Verse universe emerged this week when AT&T pushed back -- again -- the rollout of VDSL copper pair bonding technology to extend the range and throughput of its bundled IP-based U-Verse product. The new target date is sometime next year, the second delay after a planned late 2007 deployment was pushed back a year.

The obstacle is the same one that has plagued AT&T 's ADSL service: not enough good, clean copper in the telco's last mile cable plant, much of it put in place decades ago to support POTS (Plain Old Telephone Service) and never expected to support advanced digital services like ADSL let alone U-Verse. Telephony Online explains:

Perhaps a more pressing limitation, however, is the simple requirement for extra pairs of existing copper, which are not in plentiful supply in AT&T’s network outside the territory of the former BellSouth, where extra pairs were deployed extensively in the 1990s to accomodate dialup and fax services.
