T-Mobile, C-Band Alliance trade punches in battle over mid-band spectrum

While T-Mobile continues to poke holes in a controversial proposal by the C-Band Alliance (CBA) that would free up spectrum in the 3.7-4.2 GHz band for 5G, the CBA is addressing technical points raised by AT&T, Ericsson, Comcast and NCTA—the Rural Broadband Association.CBA’s attempt to address their concerns is worth noting given that one of the chief complaints during a Feb. 6 forum was the lack of transparency and answers from the group. Representatives from Charter Communications, the American Cable Association, Google and Citizens Against Government Waste participated in the panel that was hosted by the Wireless Future Project of the Open Technology Institute at New America.T-Mobile has been one of the most outspoken opponents to the CBA’s proposal, saying as recently as Monday (PDF) that it’s a “self-serving attempt to strip the Commission of its statutory obligations,” and directs all financial gains to entities that not only don’t have the terrestrial rights they propose to sell but also didn’t initially pay for the spectrum.
