Abstract
A signal quality parameter in a wireless network supporting plural network user devices is measured. Each user device measures a predetermined signal quality parameter of signals received from each of the other user devices in the network. Each user device broadcasts the measurements to other user devices in the network. Each user device calculates, for each of the other user devices, a value for the predetermined signal quality parameter from all the received measurements associated with that other user device.
Claims14
A method of managing a wireless network supporting a plurality of network user devices, the method comprising the steps of:
- at the site of each user device, measuring a predetermined signal quality parameter of signals received from each of the other user devices in the network;
- at the site of each user device, broadcasting the measurements so made to said other user devices;
- and
- managing the network using the broadcast measurements.
A method of measuring a signal quality parameter in a wireless network supporting a plurality of network user devices, the method comprising the steps of:
- at the site of each user device, measuring a predetermined signal quality parameter of signals received from each of the other user devices in the network;
- at the site of each user device, broadcasting the measurements so made to each of said other user devices;
- at the site of each user device, calculating for each of the other user devices, a value for the predetermined signal quality parameter from the measurement of said parameter associated with that other user device made at the site of said user device and from all the measurements of said parameter made at the site of the other user device as received at the site of said user device from all the other user devices;
- and
- determining that any given user device is about to leave the network by comparing said value of the signal strength associated with that user with a predetermined low level signal strength.
A wireless communications device comprising a transmitter, a receiver, a processor, an arrangement for measuring a signal quality parameter of signals received from other wireless communication devices, and a combiner arrangement for calculating a value for said parameter, for each of a plurality of said other communications devices, from the measurements so made and from other measurements of that parameter of that communications device made by said other communications devices and received by said receiver.
A method of measuring a signal quality parameter in a wireless network supporting a plurality of network user devices, the method comprising the steps of:
- at the site of each user device, measuring a predetermined signal quality parameter of signals received from each of the other user devices in the network;
- at the site of each user device, broadcasting the measurements so made to said other user devices;
- and
- at the site of each user device, calculating, for each of the other user devices, a value for the predetermined signal quality parameter (a) from the measurement of said parameter that was made at the site of the other user device and (b) from all the received measurements of said parameter made at the site of that other user device as received at the site of said user device from the sites of all the other user devices.
