­The USA's telecoms regulator, the FCC has proposed removing regulatory barriers to the use of microwave spectrum for wireless backhaul. The proposal was initially recommended in the government's National Broadband Plan. Microwave communications has become, in a growing number of situations, a viable option for backhaul of mobile broadband traffic.

Backhaul costs currently constitute a significant portion of a mobile wireless operator's network operating expense, and the demand for backhaul capacity is increasing. As broadband providers accelerate deployment of next-generation networks, they will require backhaul that can carry what is expected to be significant growth in mobile data traffic.
