Bluetooth is a wireless communication system with a short range. It makes

possible wireless connections between Bluetooth devices such as, for

example, mobile telephones, PDA and PCs. Bluetooth relates itself to a

worldwide standard for operation in the internationally recognised

ISM Frequency Range (Industrial, Scientific and Medical). Within the

ISM Frequency Range (2,402 - 2,480 GHz), a data transfer range of

approx. 10 Meters (Class II) is achieved. The disturbance susceptibility

through other users of the ISM Frequency range, such as for example

microwaves, WLAN (802.116) or garage door openers, is minimized

by so-called "Frequency-Hopping". With Frequency hopping, a change

of frequency levels takes place at up to 1600 times per second, thereby

Bluetooth is also considerd to be relatively tap proof.
