A cellular radio system includes three neighbouring cells (A3, A2, A1) which each have a number of channels (1 to 13, 14 to 26, 27 to 39, respectively) allocated for their use. A microcell M contained within cell (A1) is served by a separate base station. The microcell has available to it channels (1 to 16 and 21 to 26) from the allocations of neighbouring cells (A2 and A3). The base stations (A2, A3 and M) are controlled such that no channel is in use simultaneously in both the microcell (M) and cell (A2 or A3). This arrangement allows channels to be reallocated between neighbouring cells according to demand, without reducing the peak capacity in individual cells.
