Bluetooth

Bluetooth is a very secure and elegant, royalty-free, ultra-short range wireless network technology originally developed by Ericsson and later The Bluetooth Consortium founded by Ericsson and other big companies and now by the Bluetooth SIG.

The current version 1.1 operates in the same internationally unlicensed 2,4Ghz frequency band as WiFi or 802.11b, which has prompted a lot of uncertainty to the future of Bluetooth due to the much higher power output of WiFi appliances. Bluetooth uses frequency hopping at 1600 hops/second spread over 79 frequency slots, which makes it highly resistant to interference and Apple Computers has introduced high-end PowerBook portables with integrated Bluetooth and 802.11g to clearly state the case that these technologies can coexist on the same band (802.11g uses the same 2,4GHz band as 802.11b and is very much backward compatible with 802.11b).
