Workshop: WSUN1

"UWB over fiber"

Sunday 7 Jan., 2007
1:30- 5:30 PM

Abstract:
Ultra-wideband (UWB), regulated by the Federal Communications Commission (FCC) for indoor and hand-held UWB systems operating in the frequency range from 3.1 to 10.6 GHz with an effective isotropic radiated power level of less than -41 dBm/MHz, has recently attracted considerable interests for short-range high-throughput wireless communication and sensor networks thanks to their intrinsic properties, such as the immunity to multipath fading, extremely short time duration, carrier free, low duty cycle, wide bandwidth, and low power spectral density. However, by wireless transmission, UWB signals are only limited to short distance of a few to tens of meters. Such short-range wireless networks can operate mainly in indoor environments in standalone mode, with a nearly nonexistent integration into the fixed wired networks or wireless wide-area infrastructures. To offer availability of undisrupted service across different networks and eventually achieve high-rate data access at any time and from any place, UWB combined with fiber distribution technology may provide an effective solution. The objective of this workshop is to introduce the recent developments in the UWB over fiber technologies, including the generation and distribution of UWB signals using photonic technologies and their applications in broadband wireless access networks.
