Where does Bluetooth fit in if wireless USB comes out? It seems the same except for the data rates. I understand that Bluetooth has different specs with regards to voice.


It's happening now for a combination of reasons. The WiMedia Alliance is planning to make the technology known as "ultrawideband," or UWB, work among a wide variety of consumer electronics devices, from PCs and printers to external hard drives and MP3 players. The USB Implementers Forum, the 1394 Trade Association and the Bluetooth Special Interest Group (SIG) have chosen the WiMedia Alliance's version of UWB technology as the foundation for their next-generation networking technology. UWB technology can deliver data rates at up to 480 megabits per second at around 3 meters, with speeds dropping off as the range grows to a limit of about 10 meters. Real-world speeds will probably be a little slower, but this is as fast as the wired version of USB 2.0 and much faster than current Wi-Fi networks are capable of transmitting data.
