Abstract
A communications system is provided for emergency services personnel that includes a plurality of portable devices and a base station. The portable devices are configured to be carried by emergency services personnel while at an emergency site. The portable devices each have a first transceiver configured to communicate over a first network and a second transceiver configured to communicate over a second network, where the first and second networks operate independent of one another. For example, they may have at least one of different first and second carrier frequencies, protocol, channels and the like. The base station has at least one transceiver for communicating with the portable devices over at least one of the first and second networks. Optionally, the first and second networks may have different transmission characteristics, such as different transmit ranges, power levels and the like.
