Field Measurements of EM Radiation From In-House Power Line Telecommunications (PLT) Devices

摘要

This paper presents the results of the tests performed by the Communications Research Centre Canada (CRC) to determine the levels of electromagnetic radiation resulting from the operation of commercially available in-house power line telecommunication (PLT) devices, and to evaluate their potential effects on FM radio and low-VHF TV broadcasting services. The tests were performed when the devices were operating under real conditions in a number of typical Canadian suburban residential houses. The corresponding field strength measurements were made at specific distances from the houses and could then be compared with the present regulatory limits.
