Abstract
Aspects for reducing interference between networks are provided. A signal transmitted by 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 first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A 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.

A method for reducing interference between networks, comprising:
- decoding a signal transmitted by a first network over a communications medium using an unlicensed frequency spectrum to determine one or more parameters of a packet in the signal;
- estimating a level of utilization of the communications medium by the first network based at least in part on a signal strength of the signal and the one or more parameters;
- and
- adjusting a time for communicating in a second network over the communications medium using the unlicensed frequency spectrum based at least in part on the level of utilization of the communications medium by the first network.
An apparatus for reducing interference between networks, comprising:
- a signal decoding component configured to decode a signal transmitted by a first network over a communications medium using an unlicensed frequency spectrum;
- a signal parameters evaluating component configured to determine one or more parameters of a packet in the signal;
- a medium utilization estimating component configured to estimate a level of utilization of the communications medium by the first network based at least in part on a signal strength of the signal and the one or more parameters;
- and
- a communication time adjusting component configured to adjust a time for communicating in a second network over the communications medium using the unlicensed frequency spectrum based at least in part on the level of utilization of the communications medium by the first network.
An apparatus for reducing interference between networks, comprising:
- means for decoding a signal transmitted by a first network over a communications medium using an unlicensed frequency spectrum;
