SCOPE This st
34、andard 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 mea
35、ningful 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
36、of measurement data, that may be used for the comparison of different products. TIA-470.310-D 2 2.

Mandatory requirements are designated by the terms “shall” and “shall not”. These requirements are used to indicate conformi

These requirements generally relate to compatibility or performance advantages towards which future designs should strive. 3. Permissive requirements are designated by the terms
43、“may” and “may not”. These requirements are used to indicate an action that is permitted within the limits of the standard. TIA-470.310-D 7 5. INTRODUCTION TO RANGE TESTING PROCEDURES 5.1. ASPECTS OF RANGE Range performance, as perceived by the user, is actually the ability of the radio link between
44、 the handset and base to transfer information (e.g., voice signals, control data) without any interruptions or distortion of the information being transferred. Interruptions or distortion (noise) during RF reception may be caused by any of the following parameters: RF Attenuation (distance) between
45、the handset and the base RF interference Multi-Path Fading In a real world environment all of these parameters may have an impact on the usability of a radio link between the handset and the base. This standard is focused on making measurements of attenuation only and provides procedures for minimiz
46、ing the effects of interference and multi-path when performing range tests. 5.2. ASPECTS OF CORDLESS TELEPHONE PERFORMANCE Cordless telephone range may be evaluated for various aspects of a cordless telephone product including: Users perception of the quality of the voice channel Ability to transmit
47、 data from the base to the handset while On-Hook and Off-Hook (e.g., Ringing, Caller-ID) Ability to transmit data from the handset to the base while On-Hook and Off-Hook (e.g., Call Log Review, DTMF) The procedures for evaluating each of these (and other) telephone features are described in this sta
