How Bluetooth wireless technology deals with security issues

Security is an important issue in any wireless system. Bluetooth provides several components to ensure secure wireless connections. First, at the highest level, the application itself can provide authentication and encryption, which is essential for the most important applications. Second, the Bluetooth specification provides authentication and flexible encryption at the baseband level. The third level of security is based on the characteristics of the transmitter with low power and frequency hopping, which helps to bypass random listening devices.
