Introduction & Definition

4. Ultra-Wide Band (UWB) is a communication technology used in wireless networking to
achieve high bandwidth connections with low power spectral density.
 high data throughput
for communications
devices
 high precision for
location and imaging
devices
 high resolution for
sensing devices
 ultra low power
(microwatts)
 short signal pulses over
a broad spectrum
 limited interference
with conventional radio
systems
 high wireless data rates
in excess of 100Mbit/s
(480 Mbps up to 1.6 Gbps at
distances up to a few meters)
 data rates drop
considerably at longer
distances
