1. A system for transmitting and receiving data over a wireless interface, the system comprising:
- an ultra wide band (UWB) transceiver for transmitting and receiving radio frequency (RF) radiation along a path through an original channel in an UWB band;
at least one narrowband transceiver for transmitting and receiving RF radiation in at least one RF band having potential to cause interference with at least a portion of the original channel; and
data shifting means for shifting UWB data from said original channel to an alternative path when UWB link quality of the original channel decreases below a threshold value, the alternative path predetermined to be less affected than the original channel to interference caused by operation of the at least one narrowband transceiver.

Abstract
A transceiver capable of handling both UWB and narrowband calls includes a mechanism for detecting when a signal from one of the narrowband systems will interfere the UWB communication and switching the UWB data connection link to the alternative data path.
