Attorney, Agent or Firm:

A base station in a mobile digital system (TDMA/FDMA) utilizes a frequency hopping technique. The interconnection among receiver/transmitters (RT1-RTm) and process nodal points (NP1-NPm) takes place in base band using a common medium as distribution means of data relevant to the different users, which are entered on and sensed from at least one bus (B, B'). According to one embodiment two separate bus are foreseen, one for transmission and the other one for reception.

DETAILED DESCRIPTION This technical problem is solved with the invention which consists in a base station in a TDMA digital mobile system, in which the data associated to one user are transmitted as bit burst in a frame including n users, and in which each frame transmitted and received at a frequency changing according to a predetermined law among those assigned to the area served by the station (frequency hopping), the station including a distribution media for the baseband control of the frequency hopping characterized by the fact that said distribution media include at least a common medium (B, B') on which data are entered and sensed in time succession and at higher frequency.
Further features of the invention are reported in sub-claims.
