An analysis of portable communications technical standards

This paper will discuss the proposed new EIA standard for portable communications equipment. It will review the various sections of the standard and discuss the new methods of measurement unique to portable and the limits proposed in the standard. It will compare the measurement techniques specified for portables to existing mobile standards and highlight the differences. It will delve into the philosophies developed in the various subcommittees which contributed to the standard. Those items that are unique to the portable standard as compared to existing mobile standards will be reviewed in depth. Such items are methods of measuring size, weight, battery life, battery test voltage, open field measurement on sensitivity and power output, drop test, and duty cycle. These items represent some new philosophies which are very interesting. Some typical examples of measurements made using the standard will be analyzed in measuring a new 450 MC Two Way Portable.
