Verizon, AT&T, T-Mobile accuse each other of spectrum hoarding and market domination

Tmobile los angeles spectrum

T-Mobile is building up its inventory of mobile bandwidth, first by leasing low band, 600 MHz spectrum from a private investment firm and then, it hopes, by buying more capacity when the Federal Communications Commission auctions off C-band frequencies later this year.

That bothers AT&T and Verizon, which have formally registered their annoyance with the FCC. Although neither company publicly opposed T-Mobile acquisition of Sprint (what their lobbyists and lawyers do behind closed doors is often a different story), they’re both complaining that T-Mobile is already holding too much spectrum – exceeds the spectrum screen as the jargon goes – and shouldn’t be allowed to buy or lease any more, until AT&T and Verizon have a chance to catch up.… More

Google's wireless goal isn't fiber replacement or magic radios

No need to wait.

Google is asking the Federal Communications Commission for permission to run wireless transmission tests in and around the 3.5 GHz band, which has been designated for use under new Citizens Broadband Radio Service (CBRS) rules.
One reason for the request is sure to be Google’s increasing focus on wireless technologies as a substitute for or supplement to fiber. But Google has another, immediately practical interest at stake too: widespread use of CBRS spectrum requires real time frequency coordination amongst users, who have varying degrees of priority in that band.… More

If carmakers haven't figured out wireless in 20 years, they never will

More unlicensed spectrum for WiFi and other uses will add value to the U.S. economy. That’s the argument FCC commissioner Jessica Rosenworcel is making to congress as a matter of general policy and to colleagues as opportunities to reallocate frequency assignments are evaluated.

One immediate thing the Federal Communications Commission can do – and democrat Rosenworcel as well as republicans Michael O’Rielly and Ajit Pai want to do – is to shift 75 MHz of spectrum around 5.9 GHz (5.850 GHz to 5.925 GHz, to be exact) from an unlicensed but otherwise restricted short range, transportation-related allocation to general use.… More

Mobile carriers detail plans for adding unlicensed spectrum to their portfolios

Kind of like parking one of these in a yacht harbor. But it’s OK. They’ll be careful.

With the rate of growth – let alone growth itself – in mobile data usage continuing to boom, with no end in sight, mobile carriers are searching for new spectrum. First choice is licensed, exclusive frequencies of course, but there’s no reason for them not to grab for their second choice too, which is unlicensed spectrum.

The Federal Communications Commission has been taking comments on the possibility of mobile carriers operating alongside WiFi in the unlicensed bands.… More

U.S. military share its spectrum with the public for wireless broadband use

The U.S. defense department is giving up its sole control 100 MHz of prime spectrum – 3550-3650 MHz – which is adjacent to 50 MHz – 3650-3700 MHz – that’s already available for semi-licensed use, and the Federal Communications Commission is combining it all into a new citizens broadband radio service that will share the space with existing users. An automated spectrum access system (SAS) will coordinate use by three different classes of users with different levels of privileges.… More
