ITU Working Parties 1A and 1B will meet in Geneva between 21 and 28 June. A major item of discussion will be protection of radio services from interference from Power Line Communications (PLC) also known as PLT or BPL. IARU has already contributed to the ITU-R report SM2158 Impact of power line telecommunication systems on radiocommunication systems operating in the LF, MF, HF and VHF bands below 80MHz where the acceptable criteria for degradation of the HF radio noise floor caused by PLT is defined as being 0.5dB. Work in WP1A will concentrate on the protection of radio services from the effects of PLT in range from 80 to 200MHz.
