Concern about the safety of wireless networks is mounting,
with people blaming everything from headaches to cancer on
Wireless networks — known as wi-fi or wLAN (wireless local
area network) — are increasingly used in schools, offices
and other public places to connect computers and laptops to
the internet using radiofrequency transmitters with no need
for complex cabling. In future, whole town centres will be
transformed into wi-fi “hot spots”, enabling people to
access the internet wherever they are through hand-held
devices, including mobile phones. Indeed, Milton Keynes,
Norwich and the borough of Islington, in North London,
already have this WiMax technology.
It has taken the public a while to wake up to the idea that
wireless transmitters could be less than benign. As with
mobile phones, we first embrace the liberating new
technology and only later ask the awkward questions.
Perhaps, as with pharmaceuticals, the order should be
reversed. The official line on the health implications of
wi-fi is that exposure to low level electromagnetic
radiation from wireless networks is well below recommended
levels and that there is no evidence of risk. But despite
these soothing words, the groundswell of concern is
mounting, with some people blaming everything from headaches
to cancer on exposure to radio-frequency fields.
As reported in this newspaper, a number of schools have
dismantled their wireless networks after lobbying from
worried parents, and others are under pressure to follow
suit. In Austria the public health department of Salzburg
has advised schools and kindergartens not to use wLAN or
cordless phones. Lakehead University in Ontario, Canada,
which has 7,400 students, has removed wi-fi because of what
its Vice-Chancellor, Dr Fred Gilbert, calls “the weight of
evidence demonstrating behavioural effects and physiological
impacts at the tissue, cellular and cell level”.
Some experts have also expressed concerns. In September, 30
scientists from all over the world signed a resolution
calling for a “full and independent review of the scientific
evidence that points to hazards from current electromagnetic
field exposure conditions worldwide.” Closer to home, the
Irish Doctors Environmental Association (IDEA) has asked its
country’s Government to carry out “a full assessment of the
health impacts of electromagnetic radiation”.
“There has been no research specifically looking at the
effects of wireless networks on human health,” admits
Alasdair Philips, the scientific and technical director of
the lobby group Powerwatch. “But I have seen enough
anecdotal material to be convinced that some people are
affected by them.
