Bluetooth technology is for cable replacement & data exchange. With built-in Bluetooth
module, the mobile computer can directly communicate with any Bluetooth enabled
device, not necessarily line-of-sight.
Serial Port Profile (SPP) is for ad-hoc networking, without going through any access
point.
Dial-Up Networking Profile (DUN) makes use of a Bluetooth modem or mobile phone
as a wireless modem.
Also, it can be used to activate the GPRS functionality on a mobile phone.
Human Interface Device Profile (HID) allows the mobile computer to work as an input
device, i.e. keyboard, for a host computer.
Personal Area Networking Profile (PAN) makes use of Bluetooth Network
Encapsulation Protocol (BNEP) for IP networking over Bluetooth. Access points (AP)
are required.
