The invention concerns a system for multipoint-to-multipoint radio data transport, comprising a device for switching samples of digitised radio data called samples, transmitted by a device for the digital processing of antenna signals called antenna device (RU, RU), via a first data link (DL, DL), to a plurality of recipient antenna controller devices (DU, DU) identified by a respective plurality of controller identifiers, the switching device (DD) comprising the following modules: interception of first data frames (T, T) from the antenna device and intended for the plurality of controller devices, the first frames comprising the samples, demultiplexing the samples from the intercepted first data frames, extracting the controller identifiers from the intercepted first data frames, grouping together the demultiplexed samples by controller identifier, multiplexing the samples by group in second data frames (T, T), a second data frame being associated with a controller identifier, transmitting the second data frames via a plurality of second data links (DL, DL) associated respectively with the plurality of recipient antenna controller devices.

Multipoint-to-multipoint radio data transport

A transmission system includes: an optical transmission module capable of modulating a first digital radio signal in order to obtain a first optical signal; an optical reception module capable of receiving a second optical signal and demodulating same in order to obtain a demodulated radio signal; and a digitizing module capable of digitizing the demodulated radio signal in order to obtain a second digital radio signal. The transmission module includes: a module for adding a first management signal to the first digital radio signal, the rate of the first management signal being less than that of the first digital radio signal. The optical digitizing module includes an extraction module capable of extracting a second management signal from the demodulated radio signal, the rate of the second management signal being less than that of the second digital radio signal.
