Method for operating a network with wireless transmission of data and subscriber for said network
First Claim
1. A method for operating a network that includes wireless data transmission between a plurality of users, the network having at least two radio cells which at least partly overlap and in which different channels are used for data transmission, and each radio cell having at least one base station, the method comprising:
- interconnecting the base stations of the at least two radio cells, respectively, via at least one common communication channel;
at predefined maximum time intervals and via the base stations, simultaneously processing test cycles of a given maximum duration, wherein test signals are transmitted from the base stations in the respective radio cells during the test cycles; and
determining, within each respective radio-coupled user and based on the test signals, the communication channel with optimum transmission properties for that radio-coupled user.

Abstract
A method and device for operating a network with wireless transmission of data among a plurality of users. The network includes at least two radio cells. Test cycles of a given maximum duration are processed by the base stations at given maximum intervals in time. Test signals within the test cycles are transmitted to the respective radio cells by the base stations and are used by radio-coupled users to determine the communication channel with the best transmission properties.
