Bluetooth frequency hopping spread spectrum

WebNov 11, 2024 · Bluetooth devices communicate using low-power radio waves on a frequency band between 2.400 GHz and 2.483.5 GHz [source: Bluetooth Special Interest Group (SIG)]. This is one of a handful of bands that is set aside by international agreement for the use of industrial, scientific and medical devices (ISM). WebSep 12, 2024 · Bluetooth technology uses the frequency hopping spread spectrum technique to spread data, which is transmitted as packets. Data packets are transmitted over 79 designated Bluetooth channels. Each of these channels are separated by 1 MHz, and this defines the bandwidth of the Bluetooth classic channel.
