Bluetooth Technology

Bluetooth, which is standard on the 12-inch PowerBook G4, is an open specification that enables short-range wireless connections between desktop and laptop computers and a host of other peripheral devices. Bluetooth support is built into Mac OS X and compliant with Bluetooth specification 2.0 + EDR (enhanced data rate). It operates on a globally available 2.4 GHz frequency band (ISM band) for worldwide compatibility and has a maximum throughput of 3 Mbps.

The Bluetooth technology supports the following profiles:

• serial port (SPP) —provides a wireless serial connection to other Bluetooth devices

• dial-up networking (DUN) — enables a mobile phone to act as a modem

• object push (OPP) —enables the transfer of files between Bluetooth devices

• human interface device (HID) — enables the use of Bluetooth input devices (keyboards and mice)

• Bluetooth file transfer profile (FTP) — enables browsing of the file system of other Bluetooth devices which support Bluetooth FTP

• hardcopy cable replacement profiler (HCRP) — describes how to send rendered data over a Bluetooth link to a device, such as a printer. Although other profiles can be used for printing, the HCRP is specially designed to support hardcopy applications. Note: currently, to use this profile, Apple’s Bluetooth Update Version 1.5 must be installed.

• headset profile (HSP) — enables the use of Bluetooth-enabled wireless headsets for applications such as iChat. This profile does not enable use of Apple Speech Recognition due to the fact that it is a low-precision audio channel. Note: currently, to use this profile, Apple’s Bluetooth Update Version 1.5 as well as Firmware Update Version 1.1 must be installed.

Bluetooth shares the internal antennas with AirPort Extreme. For more information on Bluetooth technology, refer to “Bluetooth.”
