1、QUESTION ITU-R 218-1/1Techniques for measurement of radiation from high data ratetelecommunication systems using wired electrical power supply(2000-2007)The ITU Radiocommunication Assembly,consideringa) that electricity power supply continues to be used for low data rate telemetry or controlpurposes

2、 in LF bands;b) that electricity power supply is generally not designed or installed in such a way that radiofrequency (RF) radiation will be minimised;c) that new telecommunication systems are being designed which will operate with data ratesexceeding 1 Mb/s, with carrier frequencies in the HF band

3、;d) that any radiation from such systems may affect the use of radiocommunication systems,particularly at LF, MF, HF and VHF,decides that the following Question shall be studied1 What techniques are appropriate for the measurement of radiation from telecommunicationsystems utilising wired electrical power supply ?further decides1 that the results of the above studies should be included in a Recommendation or a Report;2 that the above studies should be completed by 2010.NOTE 1 See also Question ITU-R 221-1/1.Category: S2
