The FCC held a recent auction for the 3.5GHz Citizens Band Radio Spectrum (CBRS). The auction went for 76 rounds and raised over $4.5 billion for the FCC. This auction was unique in that spectrum was licensed at the county-level awarding up to seven licensed 10 MHz channels in each county. Each PAL (Priority Access License) is good for 10 years.
CBRS spectrum can be used in several applications. The spectrum has good field operating parameters and falls in the middle between the two existing blocks of spectrum used for WiFi. This makes the spectrum ideal for rural point-to-multipoint fixed wireless broadband since it can carry a decent amount of bandwidth for a decent distance. The best aspect of this spectrum is that it’s licensed and will largely be free from interference. For the same reasons, this is also a good spectrum for cellular data.
The biggest winner in the auction was Verizon which spent $1.89 billion on the spectrum. The company landed 557 PALs licenses in 57 counties. The company needed this spectrum to fill-in mid-range spectrum for 5G. Verizon has also recently announced a fixed cellular broadband product for rural homes and this spectrum could provide an interference-free way to deliver that product from rural cell sites.
As expected, Dish networks was also a big winner and will be paying $913 million for CBRS spectrum. As the newest nationwide cellular carrier, the company needed this spectrum to fill in the holes in the cellular spectrum it already controls. The other traditional cellular companies were a no-show. AT&T didn’t buy any of the CBRS spectrum. T-Mobile only purchased 8 PALs licenses in six counties.
The largest cable companies scored big in the auction. Charter bought $464 million of spectrum, Comcast is paying $458 million for spectrum, and Cox purchased $212 million of spectrum. As the newest entrants in the cellular business, Comcast and Charter have been buying wholesale cellular broadband from Verizon – this spectrum will let them shift to their own cell sites for a lot of cellular traffic. There is also speculation that cable companies might be planning on using the new spectrum to launch a fixed-wireless product in the rural areas surrounding their cable properties. Both Charter and Cox have entered the upcoming RDOF auction that is awarding $16.4 billion for rural broadband and the companies might be planning on using this spectrum to cover any areas they can win in that reverse auction.
One of the smaller cable companies, Midcontinent Communications, spent over $8.8 million for PALs licenses. Midco already won sizable rural grants to deploy 100 Mbps broadband in Minnesota and the Dakotas. This spectrum will help the company meet those grant pledges and perhaps allow it to pursue RDOF grants.
There were a few other large bidders. One was Nextlink which provides fixed wireless broadband today in Texas, Oklahoma, Kansas, Nebraska, Iowa, and Illinois. Windstream purchased over 1,000 PALs and the traditional telco is likely going to replace aging rural copper with wireless service, while also possibly be expanding into new service territories with fixed wireless. SAL Spectrum LLC won 1,569 PALs. This company owns numerous other blocks of spectrum and it’s not clear who the user of this new spectrum might be.
The biggest news is that the auction allowed smaller bidders to win licensed spectrum. There were 228 different winners in the auction, most of which are small WISPs, telcos, and electric cooperatives. These entities benefited by the FCC’s willingness to auction the spectrum at the county level. Most previous wireless spectrum was allocated using much larger footprints, which kept small bidders from acquiring spectrum.
