Introduction
Bluetooth
®
is a wireless communication system with a short range. It makes
possible wireless connections between Bluetooth
®
appliances, such as for example
mobile telephones, PDA and PCs. Bluetooth
®
relates itself to a worldwide stan-
dard 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 ca. 10 Meters (Klasse 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 minimised 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 reckoned to be relatively tap-proof.
The HSP (Headset-Profil) makes possible standard functions such as voice
transference, as well as the acceptance and rejection of calls.
The HFP (Handsfree-Profil) makes possible the hands-free call functions of a
mobile telephone, for example with the help of voice commands.
