Techopedia Explains Bluetooth Universal Serial Bus
The BT-USB standard was developed by a group of electronic manufacturers including Intel, IBM, Toshiba, Ericsson and Nokia. The standards are overseen by the Bluetooth Special Interest Group (SIG).
The BT-USB uses frequency-hopping spread spectrum. This is a radio technology that divides transmitted data into 79 bands. These bands are 1 MHz each with the range of 2402 to 2480 MHz. This range is within the worldwide Industrial, Scientific and Medical (ISM) radio band. The ISM bands are defined by the International Telecommunication Union (ITU) telecom standardization in the S5.138 and S5.150 of the Radio Regulations. However, the use of these bands by individual countries varies in their national radio regulation standards. Bluetooth is in the 2.4 GHz short-range radio frequency band.
