BPL has doubtful future: WIA
----------------------------
The Wireless Institute of Australia (WIA) seriously doubts that broadband
over power lines (BPL) technology can deliver on its promises while
overcoming its radio frequency pollution issues.
WIA Director Phil Wait said, "It sounds like a very good idea in principle,
but we believe it will fall short on implementation."
Mr Wait, who coordinates the WIA's working group on BPL, was recently
invited to appear on the weekly TekTime program on Melbourne's 3MDR FM
community radio. The WIA is the national society representing the interest
of radio amateurs.
He was interviewed for about 30 minutes and clearly explained the
regulatory and technical problems facing BPL, both here in Australia and
overseas.
The WIA Director said the bandwidth that has been achieved through BPL
tests in Australia so far is comparable with rates from ADSL cable.
Mr Wait said "The very latest BPL chip claims to deliver much higher
bandwidth. But with high bandwidth comes limited range and more
susceptibility to interference. It's the same old story that you don't get
something for nothing.
"There are two major problems with BPL technology. One is the interference
it generates and is also susceptible to, and the other is the bandwidth."
The interview provided an insight into the WIA's approach to BPL as the
technology continues to attract the interest of power companies and raise
concerns by users of the high frequency (HF) radio spectrum.
An 1,100-word report has been written on it, probably too long for a packet
bulletin, however it's available on the Amateur Radio Victoria website for
the interest of all.
