Methods for using a detector to monitor and detect channel occupancy
First Claim
1. A method of operating a device comprising:
- a scheduler, a first transceiver, and a second transceiver, the method comprising;
operating the first transceiver to send and receive packets on a first frequency during a first time period;
disabling operation of the second transceiver to send and receive packets on a second frequency different from the first frequency;
configuring the second transceiver as a detector with a receiver portion of the second transceiver;
tuning the detector to a third frequency different from the first frequency;
monitoring, with the detector, for a presence and an absence of transmissions on the third frequency;
classifying received information from the detector about the presence and the absence of transmissions on the third frequency; and
operating the first transceiver based on activity on the third frequency detected by the detector.

Abstract
Methods for using a detector to monitor and detect channel occupancy are disclosed. The detector resides on a station within a network using a framed format having a periodic time structure. When non-cooperative transmissions are detected by the network, the detector assesses the availability of a backup channel enabling migration of the network. The backup channel serves to allow the network to migrate transparently when the current channel becomes unavailable. The backup channel, however, could be occupied by another network that results in the migrating network interfering with the network already using the backup channel. Thus, the detector detects active transmission sources on the backup channel to determine whether the backup channel is occupied. Methods for using the detector include scheduling detection intervals asynchronously. The asynchronous detection uses offsets from a reference point within a frame.
