ABSTRACT:
A telecommunications network for mobile phone users comprising a user subsystem and a transport subsystem associated by means of an access subsystem, which connect to them respectively through a user access communication interface and a transport access communication interface suitable to allow the exchange of data flows between said subsystems, the access subsystem identifying a coverage area of the telecommunication network for mobile users characterized in that said access subsystem determines on the territory a separated cellular coverage for the transmission from the user subsystem to the network with respect to that from the network to the user subsystem, said access subsystem STA) being composed from, in addition to bidirectional base stations, as known, also from stations suitable to support monodirectional transmission in uplink or in downlink.
