ARLA/CLUSTER: RSGB volta a alertar para a crescente poluição radioeletrica provocada pelo BPL/PLC

[João Costa > CT1FBF]

IET article on polluting BPL technology

RSGB Electromagnetic Compatibility Committee (EMCC) member Don Beattie
G3BA/G3OZF is interviewed about Broadband over Power Line (BPL) in an
IET article

The article says:
The RSGB estimates that each BPL device, such as an in-house
power-line adapter, generates as much noise or interference as 10,000
other devices operating in the same unlicensed radio frequency bands,
emissions strong and widespread enough to also interfere ADSL
connections using overhead, rather than underground, telephone cables.
Other complaints centred on the high levels of electromagnetic
compatibility emissions caused by access BPL, suggesting that pylons
and other tall structures effectively amplify the interference.
Norweb trialled access BPL in Manchester during 1998/1999, using
street lights near the test site that served to act as antennas for
the 2-10MHz band. This reportedly caused interference to the BBC World
Service, Civil Aviation Authority, and GCHQ.
