Classic Bluetooth is designed to unify computing and communications devices around the world, connecting mobile phones to laptops. Compared to classic Bluetooth, low-power Bluetooth has a relaxed radio parameter requirement for the physical layer, which meansLower power can be used when sending or receiving data. Controller:The physical layer and the link layer

Bluetooth is an emerging technology. Its main purpose is to establish a short-range wireless communication standard around the world. It uses the 2.4-2.5 GHz ISM (industrion scientifcmedical) band to transmit voice and data. Using mature, practical, and advanced wireless technology to replace cables, it provides low-cost, low-power wireless interfaces that enable all fixed and mobile devices such: computer systems, home theater systems, cordless telep
