Abstract
Aspects for reducing interference between networks are provided. A signal transmitted by one or more devices in a first network over a communications medium using an unlicensed frequency spectrum is decoded to determine one or more parameters of a packet in the signal. A level of utilization of the communications medium by the one or more devices in the first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A period of time for communicating in a second network over the communications medium using the unlicensed frequency spectrum can be adjusted based at least in part on the level of utilization of the communications medium by the first network. In addition, a number of active transmitters over the communications medium can be determined based at least in part on identifying a source entity related to transmission of the signal, and adjusting the time for communicating in the second network can be further based at least in part on the number of active transmitters.
