Abstract:
1. A multirole device that can concurrently function as an access point and a station in a wireless network, the multirole device comprising: a baseband controller that time division multiplexes between servicing a station function, an access point function and a channel scan, the baseband controller dividing the channel scan into channel scan time slices that divide a channel scan over a plurality of channels into a plurality of channel scan time periods that are each time division multiplexed with time periods for the servicing of the station function and the access point function; and a transceiver for transmitting data received from the baseband controller to other devices of the wireless network, and for receiving and providing data to the baseband controller from the other devices of the wireless network, wherein the channel scan is a passive scan, and each channel scan time slice has a duration of a partial target beacon transmission time period, wherein the baseband controller scanning a single channel over each of a plurality of partial target beacon transmission time periods that cover an entire target beacon transmission time period, and the baseband controller transmits a clear to send to self message to the access point function prior to each channel scan time period to provide protection of the access point function from further communications from the other devices of the wireless network for a clear to send time period, each of the plurality of partial target beacon transmission time periods is being less than or equal to a clear to send time period.
