  • Patent number: 6690937
    Abstract: 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.
