Briefly, the present invention provides a dynamic channel re-assignment
capability between mobile units, base stations and sectors within base station
coverage areas. The wireless devices used in the present invention may include
impulse radio communication devices such as, for example ultra-wideband radio (also
known as digital pulse wireless) communication devices. Ultra-wideband bandwidth
and channel allocation can be effectively managed, even though link quality generally
deteriorates near the outer boundary of the base station. By maintaining dual communications
with an adjoining base station, the present invention reduces the bit error rate
and maintains signal strength (e.g., RF signal strength). This procedure is termed
a "soft-handoff".
