Ultra-wideband communication system and method
First Claim
1. A method of selecting at least one communication parameter in an ultra-wideband communication system, the method comprising the steps of:
- providing a first ultra-wideband device;
transmitting a time request message from the first ultra-wideband device to a second ultra-wideband device;
receiving a response message from the second ultra-wideband device, the response message including a transmission time;
determining a time difference between a receipt time of the response message and the transmission time; and
selecting at least one communication parameter based on the time difference.

Abstract
The present invention provides systems and methods for communication between ultra-wideband (UWB) devices. In general, the UWB device may characterize the attenuation, and other characteristics of the communication environment. Using these characteristics the UWB device can adapt various communication parameters to improve the communication quality. The UWB device may use these characteristics to establish zones and sectors for communication with other UWB devices. Based on this zone and sector assignment the UWB device may select communication parameters for communication with other UWB devices. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
