Wireless mesh access node neighboring channel quality estimation

摘要

A controller of a wireless access node is operative to estimate an adjacent one of a plurality of wireless channels while the access node is communicating over a present one of the plurality of wireless channels, comprising the controller, determining a difference between a measured signal quality of a signal communicated over the present wireless channel and a measured signal quality of a signal communicated over the adjacent channel, estimate a difference between a packet success rate of the present channel and a packet success rate of the adjacent channel based on the determined difference, and estimating a packet success rate of the adjacent channel based on a packet success rate of the present channel and the estimated difference between the packet success rate of the present channel and the packet success rate of the adjacent channel.

1. An access node, comprising:
one or more transceivers operative to wirelessly communicate with one or more upstream access nodes or a gateway through one or more of a plurality of wireless channels; wherein the access node measures a signal quality of a signal communicated through a present one of the plurality of wireless channels, and the access nodes measures a signal quality of a signal communicated through an adjacent one of the plurality of wireless channels while the one or more transceivers of the access node is communicating over the present one of the plurality of wireless channels; a controller, the controller operative to:
determine a difference between the measured signal quality of the signal communicated over the present wireless channel and a measured signal quality of the signal communicated over the adjacent one of the plurality of wireless channels;estimate a difference between a packet success rate of packets received over the present channel and a packet success rate of packets received over the adjacent one of the plurality of wireless channels based on the determined difference;measure a packet success rate of packets received by the transceiver over the present channel;estimate a packet success rate of packets received over the adjacent one of the plurality of wireless channels based on a packet success rate of packets received over the present channel and the estimated difference between the packet success rate of packets received over the present channel and the packet success rate of packets received over the adjacent one of the plurality of wireless channels;switch the wireless communication of the one or more transceivers to the adjacent one of the plurality of wireless channels when the estimated packet success rate of packets received over the adjacent channel is greater than the measured packet success rate of packets received over the present channel.
