The C-band
network is scheduled to launch in December. On October 5, 2021, the aviation
industry and the FAA argued that the C-band signal from aircraft radios, which
estimates the distance of aircraft from the ground for landing in bad weather,
should be picked up. These altimeters are designed to use the same band as the
5G network (the aircraft frequency is 400 MHz in the network launch of 2022),
but some of them are designed not to scan the surrounding frequencies, because
these frequencies are not used to power when altimeters. was built. The FAA and
air carriers agree on a two-mile "exclusion zone" around most
airports where air carriers will not launch c band first. cities like Chicago,
Dallas, New York and San Diego that are close to the airport. Our tests showed
that Verizon appears to maintain a signal beyond the two-mile limit, at least
in New York.
The FAA is
also working to review and approve altimeter models with precision filters,
although some observers wonder why the agency could not have done so a year
ago, when a different model was installed. separate for the sale. No aircraft
interference affects frequencies below 3.7 GHz. This means that it does not
affect CBRS, or T-Mobile's mid-band, or AT&T's 3.45 GHz. This gives
AT&T and T-Mobile a significant advantage over Verizon right now, as
they are able to install centralized systems near airports where Verizon is
not.
The c band is a set of frequencies in the radio spectrum ranging from 3.7 GHz to 4.2 GHz. These periods were used for television and satellite broadcasting, broadcasting and two-way radio as early as the 1970s.
