Intel demonstrates fast new Ultrawideband WPAN at IDF Taiwan
 

Although step forward several months, the UWB part of WPAN allows for amazing maximum throughput rates of up to 480Mbps (60 megabytes / second) at a range of 10 meters or less (same as Bluetooth), which matches that of USB 2.0 - hence Intel are promoting WPAN as USB without wires. At a range longer than 10 meters, Intel are recommending the upcoming 802.11n standard which has greater range than 802.11g by about 20 meters AND improves on throughput massively by offering up to 540Mbit/s compared to just 54Mbit/s offered by 802.11g.
