The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall?..Now who would want cables to dangle from those beauties?
So you think - big deal?. We have Bluetooth and 802.11 wireless technologies to solve this problem. They do a decent job of linking our pc?s and digital gadgets in the home and office. However, more bandwidth and speed is always welcome. Its here that UWB makes its grant entrance.
UWB can handle more bandwidth intensive applications ? such as streaming video ? than any 802.11 or Bluetooth technology. It has a data rate of roughly 100 Mbps. Compare that with the maximum speeds of 11 Mbps for 802.11b, called Wireless Fidelity or Wi-Fi, which is the technology currently used in WLANs (wireless LANs). Bluetooth has a data rate of about 1 Mbps. UWB is expected to reach around 500 Mbps by 2004.
Propagation environments place fundamental limitations on the performance of wireless communications systems. The existence of multiple propagation paths (multipath), with different time delays, gives rise to complex, time-varying transmission channels. A line-of-site path between the transmitter and receiver seldom exists in indoor environments, because of natural or man-made blocking, and one must rely on the signal arriving via multipath.
UWB gives us these extremely high data rates at lower costs and lower levels of power consumption, which makes it ideally suitable for handhelds and mobiles.
