There are three classes of Bluetooth devices
: Class 1, 2, and 3. The class specifies the transmit power of the device which affects the range (higher transmit power typically allows greater range). Verizon Wireless' Bluetooth capable devices are all Bluetooth Class 2 devices. They can be used with Bluetooth Class 1, 2, or 3 accessories up to a maximum range of 33 feet (10 meters).
