AT&T
Fiber is primarily aimed at business premises and multi-family buildings and
not single family homes. The company is phasing out its legacy U-Verse service
that blends fiber to neighborhood distribution equipment with copper from the
era of Plain Old Telephone Service (POTS) – metallic infrastructure it is anxious
to retire as quickly as possible to avoid the cost of maintaining it. In its
place AT&T is relying on proven and unproven radio-based technologies.
In some high cost areas of its U.S. service territory,
AT&T recently announced it would construct infrastructure designed to
deliver fixed residential premise service as part of upgrading its mobile
wireless service to 4G LTE technology. However, that infrastructure will be
obsolete the day it’s installed, not even close to approaching
what the U.S. Federal Communications Commission considers service capable of supporting
high-quality voice, data, graphics and video. It’s essentially a bolt on
afterthought to a 4G LTE mobile wireless service upgrade that will likely bog
down during peak periods as its shared bandwidth becomes saturated with heavy,
multi-premise demand.
As for the unproven radio-based technology that’s still in
the development phase, AT&T recently announced its experimental “Project
AirGig” technology. It will utilize antennas mounted atop utility poles to transmit
millimeter wave signals from pole to pole. It taps into those signals to feed
premise service based on 4G (or more optimally, AT&T’s still under
development 5G wireless technology.) The service will apparently be similar to
electrical power distribution architecture where current from high voltage transmission
lines on the tops of poles is stepped down by a transformer before it flows into a home. This
service in theory would be capable of meeting the FCC’s minimum service
standard. But at this point, it’s largely speculative and leaves much of
AT&T’s residential market segment with no clear and certain future path as its legacy copper
cable POTS plant rots on the poles.
