FCC Proposes Revisions to 5 GHz U-NII Rules
The FCC has issued a Notice of Proposed Rule Making outlining planned regulations for the 5 GHz U-NII (Unlicensed National Information Infrastructure) spectrum, including the new frequencies reported on in the May 19, 2003 RF Report.

Existing technical requirements for the 5.250-5.350 GHz sub-band would apply to the new 5.470-5.725 GHz sub band, with the addition of two mechanisms to reduce interference to other users of the spectrum. A transmit power control (TPC) mechanism would be required for operation on the new 5.470-5.725 GHz U-NII band. A listen-before-talk mechanism called dynamic frequency selection (DFS) will be required for U-NII operation on 5.470-5.725 GHz and, after two years, U-NII devices operating in the 5.250-5.350 GHz spectrum.

The FCC NPRM is seeking comments on exactly how TPC and DFS should be applied to U-NII devices in these bands. If you have an interest in this part of the spectrum, take a look at the NPRM and submit comments.

Eleven FCC Scenarios for The 600 MHz Band Plan
I suspect that the estimated $44 billion of auction proceeds do not take into account the fact that some spectrum the FCC will buy cannot be resold because it must be used as guard intervals in the 600 MHz band plan.~ Charles W. Rhodes
