Ultra wideband Technology

Ultra wideband is a wireless technology designed for a short range, personal area networks (PAN). It can allow high data throughput with low power consumption for distance of 30 meters radius. It uses the radio signals. It will be the next generation of wireless technology which can interconnect the PC peripherals, consumer electronics and other mobile devices.

UWB can transmit a data maximum 1Gbps per second. It has a frequency range of 3.1 to 10.6 GHz. It uses technique called OFDM multi-carrier system, where data bits are encoded to multiple sub-carriers, while being sent simultaneously. UWB implements wireless USB protocol based on USB-IF specification. So it enables external attach host solutions.

UWB transmitter sends the billions of pulses with the specified bandwidth of 1Gbps. The receiver translates the pulse into data by listening the pulse sequence send by the transmitter. UWB offers the security via the receiver timing schemes. UWB replaces Bluetooth’s 1-2 Mbps bandwidth with 400-500Mbps data rates. The bandwidth of 1 Gbps can be achieved in future.

The features of UWB are wireless, inexpensive, automatic, interoperability, low interference, instant PAN, upgradeable and sharing of voice and data. UWB applications include wireless control of laptop, digital camera, PDA and etc.,

The UWB technology has not been commercially released yet. INTEL has announced that commercial product will be released in few months. It is going to replace all the existing wireless technology and it will rule the entire world in the future.
