<H1>Memorandum on PLT</H1>
<P><FONT face=Verdana>The UK Parliament website shows a memorandum submitted by
the Electromagnetic Compatibility Industry Association (EMCIA) on <STRONG>Power
Line Telecommunication</STRONG> (PLT) technologies.</FONT></P>
<P><FONT face=Verdana>PLT, which also also goes by other names, including Power
Line Communications (PLC), Broadband over Power Line (BPL) and Power Line
Adaptor (PLA), has been ruining many peoples' enjoyment of radio.</FONT></P>
<P><FONT face=Verdana>The EMCIA submission says</FONT></P>
<P><FONT face=Verdana size=4><STRONG>We very strongly recommend that the
Committee specifically excludes the use of PowerLine Telecommunication (PLT)
</STRONG></FONT><FONT face=Verdana><STRONG><FONT size=4>technologies as an
option for the delivery of broadband Internet</FONT></STRONG>.</FONT></P>
<P><FONT face=Verdana>One mechanism for providing broadband Internet access
might be thought to be PLT, and similar digital communications technologies,
that use the electric power lines (the "mains") to, and within, homes to carry
the high speed data signals used by broadband Internet.</FONT></P>
<P><FONT face=Verdana>But mains wiring is unsuitable for carrying such signals,
and so PLT results in excessive electromagnetic interference (EMI).</FONT></P>
<P><FONT face=Verdana><STRONG>The very high levels of EMI emitted by PLT have
serious consequences for radio communications in the "Short-Wave" band (1 -
30MHz), including potentially severe safety consequences</STRONG>.</FONT></P>
<P><FONT face=Verdana>It can also interfere with the delivery of broadband
Internet by xDSL technologies using telephone cables, slowing their data
rate.</FONT></P>
