Short Description Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was initially conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming synchronization problems.

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHFUltra High Frequency (300-3000 MHz) radio waves in the ISM band from 2.4 to 2.485 GHzGigaHertz (GHz) 10^9 Hz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

Bluetooth can, and often does, interfere with 2.4GHz Wi-Fi channels, however the adaptive frequency hopping feature can minimise disruptions to Wi-Fi.

Frequencies[edit]

Bluetooth has 80 allocated RFRadio Frequency channels (numbered 0-79) that are 1 MHzMegaHertz (MHz) 10^6 Hz wide. 3 of these channels (37, 38, 39) are used as advertisement channels and can be identified easily as they typically constantly carry traffic.
