2.4 GHz ISM Band
|
Detailed explanation-1: -For example, Bluetooth® technology operates in the same 2.4 GHz ISM frequency band as Wi-Fi and technologies that utilize the IEEE 802.15. 4 standard.
Detailed explanation-2: -The original modulation scheme for Bluetooth was GFSK; however, the requirement for higher data rates later necessitated the addition of two forms of phase shift keying for enhanced data rate (EDR) capability: /4 DQPSK (a form of phase shift keying known as /4 differential phase shift keying.
Detailed explanation-3: -Bluetooth utilizes frequency-hopping spread spectrum technology to avoid interference problems. The ISM 2.4 GHz band is 2400 to 2483.5 MHz, and Bluetooth uses 79 radio frequency channels in this band, starting at 2402 MHz and continuing every 1 MHz.
