Parece-me mesmo mentira do "fools day" (neste caso), no entanto a
realidade oficiosa não estará muito longe neste momento ou a curto
prazo.<br>
<br>
Não sei se estará em condições de acrescentar detalhes, mas ao nível
profissional (assumo pelo email) também têm casos confirmados de
interferências nas comunicações com origem nas tecnologias PLC/PLT?<br>

could be
extinct by the year 2020. That is the only possible
conclusion to draw from an
unpublished EU policy document that has been leaked to
several ham radio
bloggers including myself. The document proposes that
existing RFI standards
protecting the short wave frequencies be torn up as
"preventing the use or
increasing the cost of essential technology in order to
protect the activities <b><span style="font-weight:
bold;">of a small number of hobbyists makes no
political
sense</span></b>." This policy has <a
moz-do-not-send="true"
href="http://www.ban-plt.co.uk/truth-lies.php">already
been unofficially in
place at the UK's Ofcom</a>, which was one of the major
contributors to the
report.<br>
<br>
The report suggests that withdrawing the standards
relating to short wave RFI
would save significant costs by removing the need to deal
with complaints about
interference. It also suggests that the UK
Telecommunications Act (and similar
laws in other EU countries) be amended to remove any right
to protection from
interference of the broadcast, amateur or CB services.<br>
<br>
To support its recommendations the report claims that
"short wave
broadcasting is in rapid decline, with most broadcasters
moving to the
internet" and that "the intended use of Citizens Band as a
personal
communications service has largely been replaced by
cellphone usage."
Amateur radio, it says, carries "little communication of
any importance
that could not be made using the telephone, cellular
network or the
internet." The main use of ham radio, it suggests, is
"largely
recreational" and could be replaced by "online simulations
and VOIP
chat services." Hams could also make more use of the
largely
interference-free bands above 400MHz which otherwise could
be sold to
commercial users. Radio amateurs "could still experiment
with radio in the
time-honoured manner, they just should not expect to be
able to enjoy
interference-free reception on the short waves."<br>
<br>
The reason for the desire to remove the protection of our
frequencies becomes
clear when you read the part of the report that describes
forthcoming
technologies that are expected to cause problems with RFI
compliance. In order
to meet carbon emissions targets and deal with expected
power shortages caused
by the early closure of nuclear power plants in countries
such as Germany, the
EU plans to introduce <a moz-do-not-send="true"
href="http://en.wikipedia.org/wiki/Smart_grid">smart
grids</a> in all European nations by 2020. These smart
grids use BPL technology
to communicate with <a moz-do-not-send="true"
href="http://en.wikipedia.org/wiki/Smart_meter">smart
meters</a> in each individual home. The smart meters, in
turn, use PLT
technology to communicate with smart devices in order to
regulate their use.
When demand for electricity is high, power cuts or the
switching on of
expensive standby power stations can be avoided by
shutting off inessential
devices instead. Examples of inessential devices given in
the report include
amateur radio linear amplifiers - assuming it's still
possible to hear anything
on short wave over the BPL and PLT QRM in the first place.<br>
<br>
The EU is also proposing that 80% of properties in member
states should be
equipped with solar panels by 2020. To achieve this
target, installation costs
will be heavily subsidized by governments, which clearly
want to cut costs as
far as possible. Estimates produced by a Chinese
manufacturer of solar power
systems suggest the cost saving that would result from
eliminating the need for
RFI suppression circuits in the power converters would
amount to 4 billion Euro
for the whole of Europe.<br>
<br>
The report concludes that "the cost of protecting the
short wave spectrum
from interference from technologies that are essential to
be installed
throughout Europe in the next decade to meet emissions
targets and maintain the
well-being of all European citizens is quite simply
prohibitive" and urges
that EU Commissioners pass the necessary laws by <o:p></o:p></span></font></p>
