Claim:
1. A method for providing radio access to a communication network for one or more mobile terminals at a local site, the method comprising: receiving, by a local transition unit at the local site, analog signals from at least one antenna and associated radio head installed at the local site, when the at least one antenna receives the signals from the one or more mobile terminals, converting, by the local transition unit, the analog signals into optical form, sending, by the local transition unit, the signals in optical form over an optical link to a central office comprising or being connected to a set of radio units, wherein the radio units in the set of radio units are capable of communicating data carried by the signals to and from the communication network according to different radio access technologies and/or for different network operators, converting, by a central transition unit at the central office, the signals into a form adapted for reception by a radio unit in the set of radio units, instructing or having instructed, by a control unit, the central transition unit to route the signals to at least one of the radio units based on configuration data of the at least one antenna and associated radio head, wherein the configuration data is used to identify which operator and radio technology of the different radio technologies and/or for different operators, the at least one antenna and associated radio head is associated with, wherein said configuration data has been registered at the control unit when received in control signalling from the at least one antenna and associated radio head, and forwarding, by the central transition unit, the signals according to the instruction from the control unit to said at least one of the radio units for digital processing and transmission over the communication network, wherein when the at least one antenna and associated radio head are installed at the local site, the at least one antenna and associated radio head: automatically issue control signals containing the configuration data and provide the control signals to the local transition unit; or issue control signals containing the configuration data to the local transition unit in response to a trigger from the local transition unit.
