Per its recommendations outlined in the National Broadband Plan, the Federal Communications Commission issued a Notice of Proposed Rulemaking (NPRM) and a Notice of Inquiry (NOI) on its Part 101 rules with the intention “to remove regulatory barriers to the use of microwave spectrum for wireless backhaul”. While the documents have not been officially released yet, the FCC notice issued following its meeting today explained them as follows:

“The NPRM explores ways to increase the flexibility, capacity and cost-effectiveness of the microwave bands below 13 gigahertz, while protecting incumbent licensees in these bands. In particular, the notice seeks to update regulatory classifications that may not have kept pace with the evolution of converged digital technologies, and to provide for increased spectrum sharing. The proposed rule changes may be particularly beneficial to rural areas, where microwave may be the only practical, high-capacity backhaul solution available to serve certain remote locations. With spectrum sharing, 750 megahertz of microwave spectrum may be made available for broadband backhaul or other advanced point-to-point uses.

The Notice of Inquiry (NOI) requests comment on further steps the Commission can take to reduce wireless backhaul costs and increase investment in broadband deployment. It asks about changes in technical rules that would enable longer links in rural areas. The NOI also inquires as to whether permitting use of smaller antennas could similarly reduce costs and stimulate investment. Finally, the NOI seeks comment on whether the Commission should examine any additional modifications to its rules or policies to promote the flexible, efficient and cost-effective provision of wireless backhaul service.”

UPDATE - August 6 - The FCC issued the Notice of Proposed RuleMaking and Notice of Inquiry late yesterday. Comments are due 60 days after this is published in the Federal Register, which means the deadline for comments will be mid-October.
