UWB (Ultra Wideband) is a radio frequency platform that
is used in the wireless device for communicating within a short distance
with high accuracy, efficiency and speed. UWB is ideally suited in
wireless home, office, electronic positioning or GPS type technology as
well as in war.
Nowadays, the revolution of wireless technology is surpassing the traditional wired technology and UWB is being the boon when it is associated with WiFi and WiMax technologies. UWB transmits the radio frequencies in pulses that reaches on destination within few nanosecond to 30 picoseconds.
These pulses transmit in a rhythmic way that can be easily recognized by the receiver.
UWB uses very low power, so it can not be detected
easily. So it is a favorite technology of the military forces. As the range
increases the speed and efficiency decreases. UWB delivers the data flow
of 480 Mbps within the range of 10 feet, on the other hand it delivers
the data flow on the speed of 100 Mbps within the range of 30 feet.
In future the speed will be up to 2 Gbps (gigabits per second) or more.
Besides these UWB is also very useful in other industries like radar, GPS technology and in mobile phones. The range of UWB can be richer and longer by using High-gain antennas that can boost the radio frequency up to one kilometer with high efficiency. The only obstacle is that there should be no radio interference within the range of UWB.
