For the first time in the FCC's 28 GHZ spectrum auction, the round-over-round increase in dollars bid across the available three thousand-plus licenses was zero.

But the auction did not close because at least one bidder employed a waiver for bidding in round 128. That zero dollar total was after the increase between rounds 126 and 127 was equivalent to buying Starbucks coffee for a small office--$80.

Bidding picked up in round 129 over 128, with bidding increasing by $310,400, including with bidding on an additional 19 licenses over the round before.

The auction is in stage 3 as of Tuesday (Jan. 15), which means unless a bidder has a waiver to use, as happened in the zero-bid round, it must bid on 100% of the licenses on which it is eligible to bid or risk losing its ability in future rounds.

The FCC concedes it has never pushed so much spectrum into the market at one time before, which could mean those lower prices, but the point is to get the spectrum out there "fast" given that wireless carriers have been talking up the need for speed and bandwidth for an internet of everything, 5G world.

The FCC will hold another (24 GHz) spectrum auction immediately following this one, and three more are in the pipeline for this year.

The spectrum auction has continued through the partial government shutdown because the staffers are paid out of auction proceeds not the appropriations currently held up by the fight over a border barrier.
