TIA ANSI/TIA-470.310-C PDF

This standard establishes procedures and criteria for evaluating Cordless Telephone Range Performance in a traditional outdoor environment as well as a controlled laboratory environment.

The intent is not to establish minimum range distances but rather, standardize range measurement procedures to allow meaningful comparisons when evaluating products. Several criteria for range performance have been identified, and it is not intended that range performance will be described by a single number or merit. Several performance measurement procedures are established, each of which yields a standardized set of measurement data, that may be used for the comparison of different products.

CATEGORIES OF CRITERIA

Three types of requirements are specified in this standard; Mandatory, Recommended, and Permissive:

1. Mandatory requirements are designated by the terms "shall" and "shall not". These requirements are used to indicate conformity in which no deviation is permitted.

2. Recommended requirements are designated by the terms "should" and "should not". These requirements generally relate to compatibility or performance advantages towards which future designs should strive.

3. Permissive requirements are designated by the terms "may" and "may not". These requirements are used to indicate an action that is permitted within the limits of the standard.
