Cell of a cellular communications network of a flow path and communication network comprising such a cell and repeater adapted to operate in such a cell

摘要

The present invention relates to a cell for a cellular communications network able to cover a circulation path of elongated in particular of a road or rail network, comprising: a base station (bts) connected to a main antenna (a) and able to emit / receive a radio signal, a repeater (r) connected to an auxiliary antenna (a), an optical fiber (10) connecting the repeater (r) to the base station (bts) and able to transmit the signal of radio communication of the base station (bts) towards the repeater (r), and vice versa, with a delay of transport connected to the propagation time in the optical fiber, the cell is characterized in that the base station (bts) comprises a device for delaying the transmission / reception, at the level of the main antenna (a), the radio signal of a delay substantially equal to the delay of transport, in order to synchronize the radio signals transmitted / received by the main antenna (a) and the auxiliary antenna (a ).
