Bluetooth
Bluetooth is a very secure and elegant, royalty-free, ultra-short range wireless network technology developed originally developed by Ericsson and later The Bluetooth Consortium founded by Ericsson and other big companies and now by the Bluetooth SIG
It operates in the same internationally unlisenced 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 Comuters has introduced some high-end PowerBook portables with integrated Bluetooth and 802.11B to clearly state the case that these technologies can coexist on the same band.
