Bluetooth

Bluetooth is a very short-range "piconet" standard for the wireless exchange of data between devices. According to the Bluetooth standard, the technology is "intended to replace the cable(s) connecting portable and/or fixed electronic devices."

Bluetooth uses 79 channels, each separated by 1 MHz, across the 2.4 GHz unlicensed band (2400-2483.5 MHz). Devices utilize frequency hopping among the 79 available channels, avoiding channels with interference due to other unlicensed and ISM devices operating in the band, such as Wi-Fi, microwave ovens, and cordless phones.

The power output of a Bluetooth device is 1-100 mW (Class 1 device), 0.25-2.5 mW (Class 2), and 1 mW or less (Class 3).

The instantaneous bandwidth of a Bluetooth transmission is defined such that the measured power in a 100 kHz bandwidth 500 kHz removed from the center frequency is at least 20 dB below the total carrier power. The standard hopping rate for Bluetooth is 1600 hops/second, and a maximum hopping rate of 3200 hops/second is employed in some modes.

The RF channel k has a frequency of 2402 + k MHz, k=0,...,78.
