What is UWB?

     

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.
