<p>A digital radio communication system (10) includes a plurality of cells (11-28) for providing two-way digital radio communication. Each of the cells (11-28) utilizes communication frames (Figs. 3A-3E) having at least one inbound communication slot and at least one outbound communication slot. The frames of each cell are of uniform length. At least some of the cells (11-28) have different bit rates than other cells. Information about the contiguous cells is provided to the radios (40) operating within a cell. The radio (40) includes a memory (55) for storing information on adjacent cells and the radio can evaluate the signal of adjacent cells for determining an appropriate cell for hand-off purposes.</p> |
