UWB systems use modulation techniques, such as Orthogonal Frequency
Division Multiplexing (OFDM), to occupy these extremely wide bandwidths.
IEEE 802.15.3a is being developed for high bit rate PAN applications, and UWB
is the most promising technology to support the stringent requirements of 110,
200, and 480 Mbps. e range for 110 Mbps is 30 feet and for higher bit rates, it
decreases. Table 1.6 summarizes UWB features [36].
For low data-rate systems (under 2 Mbps), the range can be extended to 100 to
300 meters. However, this is still a very small range for mobile broadband applica-
tions that want to be supported in ...
