Mobile phones (as well as wireless home phones) send and receive voice and text messages via radio waves. These waves – a form of electromagnetic radiation – connect your phone to a wireless network of fixed antennas called base stations. If you move out of range from one base station, the network will automatically connect you to a nearer one with a stronger signal.
The radiation given out by mobile phones is in the microwave range. It is very low level, but some experts believe long-term exposure could be damaging.
'Your phone is continually 'checking in' with its nearest base station to ensure a good connection – it's what we call a 'handshake',' explains Glynn Hughes, a former ...view middle of the document...
