Wireless UWB has the potential to replace the cables that currently connect devices.
ByUltra-wideband (UWB) usually refers to a radio communications technique based on transmitting very-short-duration pulses, often of duration of only nanoseconds or less, whereby the occupied bandwidth goes to very large values. Although the connection speed decreases quickly as a function of distance, wireless UWB has the potential to replace the cables that currently connect devices.
UWB was originally a transmission technology used by military people. UWB has been redefined as a high data rate (480+ Mbps), short-range (up to 20 meters) technology that specifically addresses emerging applications in the consumer electronics, personal computing and mobile device markets (see figure 2.20: UWB’s potential market). When compared to other existing and nascent technologies capable of providing wireless connectivity, the performance benefits of UWB are compelling.
For example, transferring a 1 Gbyte file full of vacation pictures from a digital camera to a photo kiosk would take merely seconds with UWB compared to hours using other currently available, lower speed technologies (i.e. Bluetooth) and consume far less battery power in doing so.
UWB is a wireless radio technology for transmitting data point-to-point between consumer electronics, PC peripherals and mobile devices within short range at very high speeds, while consuming little power. Therefore, it is ideally suited for transfer of high-quality multimedia content, such as the wireless streaming of family videos from the digital video recorder to a high-definition television in the living room, or wirelessly connecting a mobile PC to a projector in a conference room to deliver a presentation.
