Dual mode operation in a wireless network

摘要

Provided is dual mode operation by a communicating device in wireless network. The communicating device selects a radio frequency (RF) channel and a physical layer type. The communicating device processes signals received via the selected RF channel based on the selected physical layer type. The communicating device may determine whether a beacon frame has been detected base on the signals that were received via the selected RF channel and processed based on the selected physical layer type. When a frame is not detected, the communicating device may determine a signal energy level for the received signals. The communicating device may establish an association with an existing network based on detection of the beacon frame or the communicating device may transmit an originating beacon frame based on the determined signal energy level.

主权项

1. A method for communicating data in a wireless personal area network (WPAN), the method comprising:
processing received radio frequency (RF) signals based on a selected physical layer type to produce processed signals; determining, based on the processed signals, whether a beacon protocol data unit has been detected; and when the beacon protocol data unit has not been detected:
determining a signal energy level for the received RF signals via the processed signals when a protocol data unit has not been detected; andtransmitting an originating beacon protocol data unit based on the determined signal energy level.
