Abstract :
A comparative system study has been made to determine the performance requirements of a pocket carried receiver, which is compatible to existing land-mobile vehicular communication systems and can be used to extend their range of operational flexibility. The study employs a medium frequency analysis as a model. Using this method, a similar process yields the minimum performance specifications for frequencies of 43 and 150 mc. It is determined that such a device can be practically utilized within the desired range of coverage. A typical receiver now in production is described and a discussion of present and future applications illustrated.
