DoW flags hurdles in securing 400MHz blocks for 6G

A US Department of War official said the biggest technical challenge for 6G is securing contiguous 400MHz downlink channels without disrupting military systems. An OMB memorandum aims to speed up federal spectrum reallocation, with the FCC and NTIA targeting up to five auctions by the end of 2028.

• 6G standards envision contiguous 400MHz downlink channels
• OMB reform lets FCC and NTIA run band studies and auction prep in parallel
• Candidate bands include 1.6GHz, 2.7GHz, 4.4GHz and 7GHz
• Congress mandates 800MHz of spectrum for commercial mobile services
