The applications of the top spectrum winners--Straight Path Spectrum, ($3,417,133,445), FiberTower Spectrum Holdings ($2,379,103,897), and T-Mobile ($931,609,379)--passed muster, though the FCC points out that the approval is an initial pass. 

"The Commission may return or dismiss the applications, however, if upon further examination, they are found to be defective or not in conformance with the Commission’s rules." 

A number of other bidders have also passed initial muster, but not all winning bidder applications have secured initial approval. The FCC said it is still vetting some of those.  

The FCC's Spectrum Frontiers auction of high-band spectrum for 5G (auction 103) closed March 12, raising $7,558,703,201, with $3,084,172,898 going to pay off existing licensees and the FCC netting $4,474,530,303.  

The 35 qualified bidders in the auction competed for a whopping 3,400 MHz of flexible use, millimeter-wave, spectrum (in the upper 37-gigahertz, 39-GHz and 47-GHz bands), the most spectrum the FCC has ever offered in an auction of any type. The spectrum — which was offered as 14,144 licenses — can be used for both fixed and mobile broadband and was auctioned in 100-megahertz blocks in partial economic areas (PEAs).
