  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates generally to a transportable communications system, and more specifically to a transportable communications system for use in a disaster environment.\n\n2. Related Art\n\nModern communities are serviced by wire line and wireless communications systems, such as land line and cellular telephone systems. These systems are designed to carry nominal traffic loads under normal operating conditions. However, during special events, such as emergencies, large traffic loads occur for which the capacities of these systems may be inadequate, and possibly even impaired. For example, during a hurricane, above ground telephone poles, wires, and cellular antennas may be blown down, thereby disrupting commercial communications systems. Only special governmental communications services may remain operational for emergency applications.\n\nThe present invention is a transportable communications system (hereinafter \"the system\"). The system can be installed in a region requiring supplemental communications services in case of a special event, such as an emergency.\n\nIn one embodiment, the invention is implemented with a wireless cellular topology. In this embodiment, the invention comprises a system of cell sites, wired access points (WAPs), and a common point coupling a user terminal to an established communications network, such as a long distance telephone network. As a result, the user terminal and the established communications network can transmit information, such as data and voice, to one another.",
