1. A channel management method, comprising:
- determining utilization of a primary wireless channel;
determining utilization of a secondary wireless channel;
comparing utilization of the primary wireless channel with utilization of the secondary wireless channel;
designating the primary wireless channel a new secondary wireless channel;
designating the secondary wireless channel a new primary wireless channel; and
routing wireless data communication between a remote data concentrator and a wireless node from the primary wireless channel to the secondary wireless channel if the utilization of the secondary wireless channel is lower than the utilization of the primary wireless channel,wherein designating the secondary wireless channel a new primary wireless channel includes switching a transceiver monitoring the secondary wireless channel into an active mode, wherein the transceiver transmits and receives data communication over the new primary wireless channel.

Abstract
A channel management method includes determining utilization of a primary wireless channel, determining utilization of one or more secondary wireless channels, and comparing utilization of the primary wireless channel with utilization of the each of the one or more secondary wireless channels. If utilization of a secondary wireless channel of the one or more secondary wireless channels is lower than the utilization of the primary channel, data communication between a data concentrator and a remote wireless node is routed from the primary channel to the secondary channel.
