Ofcom has successfully completed the auction of frequencies in the 412-414/422-424MHz band, using a combinatorial sealed bid auction. DotEcon assisted Ofcom in the design and implementation of the auction for the award of four spectrum blocks in the 412-414/422-424MHz band. Six bidders participated in the auction in which they were able to submit bids for all feasible package combinations. Winning bids were determined using DotEcon’s WebBidder Software. The auction results can be found on Ofcom’s website.
