It used Radio Relay and Satellite technology. Its design and development gave the necessary impetus to manufacturers to use the technology to develop a civilian system, which soon outstripped the military development. The system included the Single Channel Radio Access (SCRA) vehicles, which can be seen as mobile masts and transmitters, which gave an extended area of access to subscribers. As the transmitters were housed in armoured vehicles or trucks the whole system was dynamically mobile.
It was a portable phone, which could be used on the move and could synchronize with different 'cells' in separate geographical locations. This was an Army first and the forerunner of mobile phones.
