DFS operation in FCC U-NII-2C

650-01-42 supports the FCC 5.4 GHz (U-NII-2C) band under the rule changes recently introduced. The band available for U-NII devices has been extended to cover all of the spectrum between 5470 MHz to 5725 MHz, making an additional 50 MHz available for unlicensed use. At the same time, the firmware complies with rule changes requiring more effective detection when operating co-channel with a terminal Doppler weather radar (TDWR).

To take advantage of the additional 50 MHz of spectrum, generate a new License Key for the United States using your existing MAC address at The 5.4 GHz band is now selected using Regulatory Band RB 9.

Operation in Canada continues to be supported using RB 13. Operation in Chile, Colombia and Kenya continues to be supported using RB 12.
