What is the range for Bluetooth wireless communication?
The “default” 0dBm Bluetooth radio is intended to operate at a nominal range of 10 meters. A power-amplified 20dBm radio is also specified, with a range of about 100 meters. Of course, because Bluetooth wireless technology uses RF communications, the range can be affected by obstacles in the communication path that might obstruct or refract the radio waves. Most of the usage cases included in the version 1.0 specification assume a 10-meter radio range.
