1. A method of communicating among stations coupled to a shared communication medium, comprising:
- receiving signals from a first plurality of the stations in a first network through the shared communication medium that is shared with a second plurality of the stations in a second network,determining signal strength values for each of the received signals from the first plurality of the stations in the first network based on at least a portion of a detected preamble of a received signal, wherein the detected preamble is received at a higher signal strength than a remaining portion of the received signal,receiving an indicator of signal strength values determined for received signals among the second plurality of the stations in the second network; and
based on the signal strength values for each of the received signals from the first plurality of the stations in the first network and based on the indicator of the signal strength values determined for the received signals among the second plurality of the stations in the second network, selecting a detection threshold such that, in response to a signal having a signal strength in excess of the detection threshold, the signal is processed according to a protocol of the first plurality of the stations and is not processed according to a protocol of the second plurality of the stations.

Abstract
Disclosed are systems and methods for communicating among stations coupled to a communication medium by receiving signals from a plurality of the stations, determining signal strength values for each of the received signals based on at least a portion of the signal, and based on the signal strength values, selecting a detection threshold such that, in response to a signal having a signal strength in excess of the detection threshold, the signal is processed according to a protocol of a subset of the stations.

18. A method of communicating among stations coupled to a communication medium, comprising:
-
receiving signals from a first plurality of the stations in a first network through the communication medium that is shared with a second plurality of the stations in a second network; determining signal strength values for each of the received signals based on at least a portion of a detected preamble of the received signals, wherein the detected preamble is received at a higher signal strength than a remaining portion of the received signals; based on the signal strength values, selecting a detection threshold such that, in response to a signal having a signal strength in excess of the detection threshold, the signal is processed according to a protocol of the first plurality of the stations; and sending a pending transmission from a first station of the first plurality of the stations in a first network to a first destination station of the first plurality of the stations based on a determination by the first station whether a second destination station of the second plurality of the stations of an ongoing transmission is affected by the pending transmission. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A communication system, comprising:
-
a shared communication medium; and multiple stations coupled to the shared communication medium, each station configured to receive signals from a first plurality of the stations in a first network through the shared communication medium that is shared with a second plurality of the stations in a second network, determine signal strength values for each of the received signals from the first plurality of the stations in the first network based on at least a portion of a detected preamble of a received signal, wherein the detected preamble is received at a higher signal strength than a remaining portion of the received signal, receive an indicator of signal strength values determined for received signals among the second plurality of the stations in the second network; and based on the signal strength values for each of the received signals from the first plurality of the stations in the first network and based on the indicator of the signal strength values determined for the received signals among the second plurality of the stations in the second network, select a detection threshold such that, in response to a signal having a signal strength in excess of the detection threshold, the signal is processed according to a protocol of the first plurality of the stations and is not processed according to a protocol of the second plurality of the stations.
