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 method, comprising:
selecting, at a wireless device, a primary network channel from a plurality of network channels, wherein the primary network channel is selected from the plurality of network channels based on an interference level of the primary network channel; selecting an alternate network channel from the plurality of network channels, wherein the alternate network channel has a respective interference level which is below a threshold interference level; switching from the primary network channel to the alternate network channel; and switching back to the primary network channel in response to a number of neighbor devices present on the alternate network channel.
