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 (RU1, RU2), via a first data link (DL11, DL12), to a plurality of recipient antenna controller devices (DU1, DU2) identified by a respective plurality of controller identifiers, the switching device (DD) comprising the following modules: interception of first data frames (T11, T12) 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 (T21, T22), a second data frame being associated with a controller identifier, transmitting the second data frames via a plurality of second data links (DL21, DL22) associated respectively with the plurality of recipient antenna controller devices.
