Broadband carrier frequency selection
First Claim
1. A method of dynamically selecting carrier frequencies for carrying a broadband channel, the method comprising:
- allocate a group of carrier frequencies for carrying the broadband channel;
identify a number of alterative groups of carrier frequencies;
monitor a performance parameter of the broadband channel for the allocated group of carrier frequencies;
re-allocate the broadband channel to be carried by one of the alternative groups of carrier frequencies in response to the monitored channel performance degrading below a threshold.

Abstract
The present invention relates to broadband wireless communication using multiple carrier frequencies, and the selection or allocation of those frequencies. The invention is particularly but not exclusively related to ultra wideband (UWB) technologies. The present invention provides a method of dynamically selecting carrier frequencies for carrying a broadband channel, the method comprising: allocate a group of carrier frequencies for carrying the broadband channel; identify a number of alterative groups of carrier frequencies; monitor channel performance of the broadband channel for the allocated group of carrier frequencies; re-allocate the broadband channel to be carried by one of the alternative groups of carrier frequencies in response to the monitored channel performance degrading below a threshold.
