Cell for self-configuring wireless communication network

Abstract

A cell, preferably a stand-alone device, arranged for wireless communication with a plurality of other cells in a communication network, e.g. a TDMA network such as a DECT based network. The cell includes a processor performing a selection algorithm which selects a reference cell among other cells. The selection algorithm bases the selection on a wireless signal, e.g. an RF signal, received from at least two other cells. Further, the cell includes a wireless receiver for receiving a first wireless signal, e.g. an RF signal, from the reference cell with time synchronization information for the reference cell. The cell includes a wireless transmitter which transmits time synchronization information for the cell itself represented in a second wireless signal, e.g. and RF signal. The selection algorithm selects the reference cell based on transmission link quality measurements and cell path information received from a number of cell candidates. The cell preferably also itself transmits cell path information, e.g. at regular intervals. Preferably, the cell can generate a random number and transmit it in wireless form as its cell identity code. A network of such cells can be self-configured, i.e. no manual action is required. Further, it allows changes in network topology, e.g. change of position of one or more cells, since each cell can automatically adapt to a new topology and select the most reliable reference cell to synchronize to.
