FREQUENCY AGILITY FOR AN ISM BAND HOME AREA NETWORK

摘要

Due to interference that typically occurs in the ISM band, it may be necessary for one or more network devices to switch to an alternative channel. A list of one or more alternate network channels may be generated by a coordinating/gateway device based on the energy level and a distance from a primary network channel. The alternate network channel list may be distributed to neighbor devices and, in the event of interference, link loss, and/or a channel switch notification, the neighbor devices may automatically switch to the first alternate network channel in the list.

主权项

1. A computer-implemented method, comprising:
during formation of a network, determining an energy level for a plurality of network channels; selecting one of the plurality of network channels with a low energy level; selecting at least one alternate network channel, wherein the at least one alternate network channel is below a threshold energy level and is distal to the selected one of the plurality of network channels; and communicating the at least one alternate network channel to at least one device on the network.
