Bluetooth® is a wireless technology used for exchanging data between devices over short distances. The Bluetooth standard is maintained by the Bluetooth Special Interest Group (SIG).
The Bluetooth Classic standard specifies two PHY modes: Basic Rate (BR) and Enhanced Data Rate (EDR). In addition, the more recent Bluetooth Low Energy (LE) standard focuses on applications in the healthcare, fitness, security, smart building, and home entertainment industries. Bluetooth design challenges exist in the areas of transceiver chip design, coexistence modeling, mesh networking performance, RF design, and localization performance.
