National transportable telecommunications capability

The chance to integrate two emerging telecommunications technologies together, the Ku-band satellite communication (SATCOM) and cellular, offered the unique opportunity to package a truly stand-alone capability to reconstitute telecommuications service. Terrestrial cellular telephone services have proven to be an essential tool for dealing with local emergencies to the extent that they survive and remain operable, as in the San Francisco earthquake. Cellular telephones can provide emergency coordinators the flexibility of wireless mobility in the field via the Public Switched Network (PSN) to coordinate emergency services. However, not all areas are covered by cellular service; existing cellular and PSN service availability could be limited by the congestion and competition for the dial tone that occurs in emergencies. It was realized that a critical need exists for a rapidly deployable stand-alone cellular capability coupled with alternate connectivity to bypass congested or damaged PSN links. Existing commercial Ku-band satellite communications have provided alternate routing links in some cases to support emergency communications. An emergency operational capability was conceived that integrates these technologies into a rapidly deployable and transportable package that provides both local and long distance telephone services to an area that has suffered widespread telecommunications outages or has been totally isolated from the world.
