A new mobile communications systems standard

Summary form only given, as follows. IEEE Standard 184, "IEEE Test Procdure for Frequency-Modulated Mobile Communications Receivers," has been completed after seven years of work by members of the G-VT Mobile Communications System Technical Committee. In February, 1962, the IRE Standards Committee requested that a review and updating of the then existent Standard 49 IRE 16.51 be undertaken by the Mobile Systems Committee TC 16.0. This review established a need for a complete revision, recognizing the limited scope of performance which the previous standard demonstrated. The more rigorous demands of spectrum utilization dictated a discipline of performance evaluation which would support the application of equipment designed to work in a densely populated spectrum environment. In addition, it was recognized that the users of mobile communication equipment had no uniform basis for comparing the performance of equipment procured to a general specification. It was also recognized that a standard which was system oriented would enable more accurate performance levels to be established. Another benefit, not so obvious, is the accumulation of a uniform set of definitions of terms peculiar to the mobile communications field. The G-VT Subcommittee (TC) 16.2 is anxious to have the benefit of demonstration by as many engineers in the vehicular radio field as possible and will welcome their comments and recommendations for future standards. This is particularly true of another G-VT oriented Standards Committee, G-EMC (TC) 27.7, which is working on a Method of Measurement of Spurious Emissions from Land-Mobile Communications Transmitters. Many of the same people are involved who were instrumental in developing Standard 184. The technical committee's next project will be a similar standard for transmitter measurements.
