Abstract:
1. A method of reducing the mutual interference of network subscribers in radio networks, wherein, within a cellular radio network comprising at least two radio cells, in one of these radio cells devices assigned to said radio cell communicate with one another or via a common access point, characterized in that the cell size of a radio cell is adjusted by reducing the receiver sensitivity of a device belonging to the radio cell if the device receives interference which disrupts its communication from another device belonging to a different radio cell, wherein a received signal strength of a data packet that is received in the device is measured in a physical layer, that data packet and the received signal strength are classified depending on whether they are from the device's own radio cell or from another radio cell based on a MAC address, wherein a link safety margin is determined, which is obtained from the difference between the minimum received signal strength of the device and the maximum sensitivity of the device minus a safety range, wherein the link safety margin is used to reduce the receiver sensitivity of the device.
