BLUETOOTH BASIC FUNCTION • Bluetooth networking transmits data via low power radio waves. • It operates in ISM band at 2.4 GHz (Exactly between 2.402GHz to 2.480 GHz). • It can operate in noisy frequency environments as it uses a fast acknowledgement & frequency hopping scheme to make the link robust. • Bluetooth devices avoid interfering with other systems by sending weak signals of about 1mW. • It can connect upto 8 devices simultaneously. 24/10/2009
