The invention is directed to an improved two-way radio network system (15). In the preferred embodiment, the system comprises a radio (16), a first tower (17) having a defined first coverage area (23) and capable of communicating with the radio when the radio is in the first coverage area, a second tower (18) communicating with the first tower and having a defined second coverage area (24) and capable of communicating with the radio when the radio is in the second coverage area, a local hub (53) communicating with the first tower and the second tower, the first tower, second tower, and local hub so configured and arranged that a signal from the radio when the radio is in the first coverage area may be received by the first tower and communicated either to the second tower or to the local hub and communicated from the local hub to the second tower, whereby the communication capacity of the system may be increased. The communication network system may include a third tower (29) having a defined third coverage area (35) capable of communicating with the radio when the radio is in the third coverage area, a second local hub (54) communicating with the third tower, a first regional hub (56) communicating with the first local hub and the second local hub, the first regional hub, the first local hub and the second local hub so configured and arranged that a signal received by the second local hub may be communicated to the first regional hub and communicated from the first regional hub to the first local hub. The communication network system may include a second regional hub (58), a first district hub (62) communicating with the first regional hub and the second regional hub, the first regional hub, second regional hub, and first district hub so configured arranged that a signal received by the first regional hub may be communicated to the first district hub and communicated from the first district hub to the second regional hub.
