AT&T is claiming a C Band first, saying that it has successfully completed 5G field test calls using test devices and a Mobile Test Platform at locations in Plano, Texas and Detroit, Michigan.
Operators want to move as quickly as possible to start utilizing the C Band spectrum. Verizon and T-Mobile US have also already begun C Band testing, and Verizon has said that it already has work underway to deploy around 7,000 sites that will be ready to be lit up as soon as the first tranche of spectrum is available this December.
