If FCC auction officials believe in lucky numbers, seven sounds like it could be theirs.

In the seventh round of the FCC's auction of 28 GHz spectrum, the bid total rose to $77,542,190, $7,965,750 (11.45%) over the previous round's total.

In round seven there were 2,138 provisionally winning bids (PWBs), which means licenses that have now been bid on, up from 2,121 PWBs the round before.

Four bids totaling a little over $2 million were withdrawn in the round, all in Pennsylvania.

As of this latest round, 934 license have yet to be bed on or have been withdrawn.

The FCC launched the auction Wednesday (Nov. 15) with two, two-hour rounds. Bidding is now being conducted in three, one-hour rounds until further notice, which is a way to goose the bidding, with another 5G spectrum auction scheduled to start after this one closes.

Starting tomorrow (Nov. 20), the bidding will move to four, one-hour, rounds per day, but with no bidding Nov. 21-24 (Wednesday-Friday) for the long Thanksgiving pre-weekend.
