PARALLEL SCANNING OF WIRELESS CHANNELS

摘要

Methods, systems, and apparatus for parallel scanning of channels in communication networks are described herein. A parallel scanning device performs a scanning operation that includes parallel (i.e., simultaneous) scanning of channels that are in a common frequency band or in different frequency bands. The parallel scanning of channels results in a reduction of scan time, which reduces power consumption. Furthermore, a scanning operation may undesirably interrupt and/or delay normal communication traffic to and from the parallel scanning device, and the comparatively shorter scan time resulting from the parallel scanning operation can reduce such interruption and/or delay.

1. In a parallel scanning device that includes a first transceiver and a second transceiver, a method comprising:
receiving an indication at the first transceiver, which is associated with a first access point that is configured to communicate via a first channel, that the second transceiver is to provide a probe request via a second channel that is adjacent to the first channel, the probe request configured to discover one or more second access points that are available to connect with the parallel scanning device via the second channel; and turning off the first transceiver in response to receiving the indication.
