Program for adjusting channel interference between devices in a wireless network

A computer-readable medium encoded with a program product for use in a first fixed-location device capable of communicating in a wireless communications environment via a radio frequency channel, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:

• logic for detecting that a second fixed-location device is also using the radio frequency channel;
• logic operating in response to the detecting logic for adjusting transmit power to decrease interference with the second fixed-location device in response to a message received from the second fixed-location device, the message indicating the power level of the second fixed-location device, including:
• logic for ascertaining whether the second fixed location device is nearer to the first fixed location device than a first mobile device that is associated with the first fixed location device;
• and
• logic for adjusting transmit power such that:
• if the second fixed location device is nearer to the first fixed location device than the first mobile device, transmit power is set based on distance to the first mobile device;
• and
• if the second fixed location device is not nearer to the first fixed location device than the first mobile device, transmit power is set based on distance to the second fixed location device.

A computer-readable medium encoded with a program product for use in a first fixed-location device capable of communicating in a wireless communications environment via a radio frequency channel, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:

• logic for maintaining a known devices table, wherein the known devices table includes an entry for each other fixed-location device operating on the radio frequency channel, and wherein for each entry, a backoff value is recorded for each other fixed-location device, the backoff value for each fixed-location device indicative of an amount that the fixed-location device's power has been adjusted;
• logic for setting the transmit power of the first fixed-location device to a level equivalent to maximum transmit power minus the maximum of the backoff values recorded for each other fixed-location device, including:
• logic for ascertaining whether the second fixed location device is nearer to the first fixed location device than a first mobile device that is associated with the first fixed location device;
• and
• logic for adjusting transmit power such that:
• if the second fixed location device is nearer to the first fixed location device than the first mobile device, transmit power is set based on distance to the first mobile device;
• and
• if the second fixed location device is not nearer to the first fixed location device than the first mobile device, transmit power is set based on distance to the second fixed location device.
