Technical Tradeoffs for Spectrum Efficiency in a Personal Radio Service
Citizen's Band (CB) radio channels are already badly congested in large metropolitan areas, and the number of licensed sets is increasing several million per year. In addition, interference from skywave propagated CB signals during the three years near the peak of the next solar cycle (two to four years from now) will probably significantly decrease the opera tional range of users in less congested parts of the country. 1 ' 2 As a result, the Federal Communications Commission (FCC) has been studying the possibility of establishing a new Personal Radio Service to supplement the Citizen's Band service.
