Mobile telecommunications network with distributed base stations

Radio head for connection on one side for use as a shared resource on a local area network (LAN) and on another side for communicating with mobile terminals via an air interface, the radio head comprising:

• an interface to the LAN for receiving from a concentrator outgoing channel coded radio signals, and transmitting to the concentrator non-demodulated incoming radio signals received from the mobile terminals;
• a unit for modulating the received outgoing channel coded radio signals;
• and
• a synchronizing unit for receiving signals from the LAN for remote control by the concentrator of a local timing signal required for operation of the radio head.

A distributed base station connectable with a mobile radio communication network, comprising:

• a radio head for connection on one side for use as a shared resource on a local area network (LAN) and on another side for radio communication with one or more user terminals compatible with the mobile radio communication network;
• and
• a concentrator for connection on one side to the mobile radio communication network, and for connection on another side on the LAN,
• the concentrator comprising:
• a LAN interface to a local shared resource network for receiving from the radio head incoming radio samples and transmitting to the radio head outgoing radio signals, and
• digital signal processing units for:
• channel coding at least user messages and/or signaling messages to generate the outgoing channel coded signals,
• transmitting the outgoing channel coded signals to the LAN interface for transmission from the radio head,
• demodulating the incoming radio samples received via said LAN interface of the concentrator from a mobile radio terminal via the radio head, and
• remote controlling a local timing signal required for operation of the radio head on the LAN,
• the radio head comprising:
• a LAN interface to the local shared resource network for receiving from the concentrator the outgoing channel coded radio signals, and transmitting to the concentrator non-demodulated incoming radio signals received from the mobile terminals,
• a unit for modulating the received outgoing channel coded radio signals, and
• a synchronizing unit for receiving signals from the LAN for remote control by the concentrator of the local timing signal required for operation of the radio head.
