Phones are now offered on the 5.8 GHz band to remedy this, and Bluetooth has taken its own steps to reduce interference and improve transmission quality. Version 1.1 of the Bluetooth standard is much lower interference issues, but requires a very differenthardware of the original standard 1.0c, thus eliminating any possibility of backwards compatibility.

The typical feature of Bluetooth indicate a maximum transfer rate of 723 kbps and a range of 2-10 meters (65-328 feet – depending on class of device).
