BT Powerline Adaptors Trigger Interference Complaint
By: MarkJ - 15 January, 2009 (1:42 PM)

BT's broadband based Internet TV (IPTV) service, BT Vision, is under pressure after a campaign group complained that the optional Comtrend Powerline Ethernet (LAN) adaptors it supplies with the service can cause EU standards breaching levels of interference.

Powerline technologies have long been associated with interference, though the adapters supplied by BT have apparently given shortwave radio using members of the UKQRM campaign quite a headache and made their hobby increasing difficult:


To date roughly 40 complaints about the matter have been made to Ofcom, although the regulator is apparently powerless to act because the devices carry a CE Mark for appropriate standards.

Instead the campaigners have taken their argument to Trading Standards, sighting independent tests carried out by EMC. These would appear to indicate that the adaptors do not conform to the appropriate EN55022 standard. More @ The Register.
