A system including first and second network nodes that communicate with additional nodes in first and second networks, respectively, using a shared communication channel. In response to detecting presence of the first network node, the second network node transmits a first signal to the first network node including a predetermined sequence known to both the first and second network nodes. The first network node measures a strength of the transmitted signal based on knowledge of the predetermined sequence and calculates a throughput metric (throughput referring to amount of information transmitted per second) based on the measured strength. In response to the throughput metric being less than a unification threshold, the first network node selectively transmits a unification request to the second network node. The unification request invites the second network node to coordinate operation with the first network node to reduce interference between the first network and the second network.

System for selectively unifying overlapping networks to coordinate communication channel usage

A method for sharing a communication channel between a first network and a second network. The method includes transmitting a signal from the second network to the first network in response to the second network detecting presence of the first network. The signal includes a predetermined sequence measuring the strength of the signal arriving at the first network and transmitting a unification request from the first network to the second network when a metric based on the measured strength is less than a unification threshold. The unification request invites the second network to coordinate operation with the first network to reduce interference between the first network and the second network.
