Cellphones or Mobile Phones

you will need a media viewer to see it.
Cellphones send and receive signals that are encoded or
decoded to produce audio or visual messages. The cellphone turned on is
constantly in touch with the closest cellsite/mobile phone base station, so
the network knows where to send the calls quickly. When you make a call, the
signal is encoded and sent to the nearest cellsite of your service provider
and then off via microwave link or cable to the network, to connect you to the
recipient.
When you are on the move the cellphone reaches for a new
cellsite to take the call. If you move into an area where there are too many
calls going through the cellsite your call will cut off. If you move into an
area and someone else is on the phone on that frequency, your call will cut
off. If you move into an area where there is little coverage, your call will
cut off and if you move into an area where there is alot of interference from
other frequencies such as Radio or Television transmissions, your call will
cut off.
The UK's National Radiological Protection Board (NRPB)
confirms significant absorption of microwave energy in the eyes and their
sockets, brain, nose, tongue and surrounding muscles. A senior adviser to the
NRPB has been reported in the British press as saying: "It is not unreasonable
to suggest that this might cause some damage." The worry is that these overt
symptoms may be the precursors to more serious problems and not all users are
getting these early warning signals.
Is the problem more serious ?
Research funded by the New York Heart Research Foundation as early as 1992,
showed that microwave radiation from a relatively low powered analogue mobile
phone, caused chemical changes in the brain similar to those present in
cancerous and precancerous situations, which were still measurable more than 7
days after just one 3 minute phone call. The emissions from cellphones

Despite a 6 fold increase in car accidents while driving
and using a cellphone, the New Zealand government through the LTSA, Land
Transport Safety Authority, stopped accepting submissions on cellphone use
while driving and decided to conduct it's own research, when other countries
have accepted the research and have imposed bans on driving while using a
cellphone, and simply pull off the road while talking on the phone, see
Direct
Line Motor Insurance Report. The recent Transport Ministry
study found that 1 in 10 accidents between 2002 and 2003 involved the driver
being distracted by something in the car. Cellphones and other
communications devices contributed to 9 deaths and 159 injuries.
After a few fires at petrol stations,
most carry a warning to stop using cellphones near petrol pumps.
The use of cellphones at the beginning and end of an airplane
flight was thought to interfere with flight equipment and has been banned
on most flights, and for the same reason many hospitals have banned their use
near sensitive equipment. You may find health warnings in cellphone
instruction booklet's fine print warning of potential hazards with cellphones
and pacemakers, yet the concept that cellphones may interfere with
people is never discussed.
