How the mobile phone system works
The mobile phone system works like a two-way radio, and includes the
individual handset and the base stations. Base station antennae are mounted
high off the ground (on a tower or roof) to get the widest coverage. A mobile
phone has a radio receiver and a transmitter.
When you make a call, your phone uses radiofrequency (RF) radiation via its antenna to ‘talk’ to a nearby base station. Once the base station has received your signal, your call is directed through the landline phone system.
Mobile phone base stations emit relativelyconstant levels of RF radiation. The handsets emit levels of RF radiation that vary depending on three things:

Mobile phone base stations emit relativelyconstant levels of RF radiation. The handsets emit levels of RF radiation that vary depending on three things:
·
how long you use the phone
·
how close you are to the base station. If the link to the
base station is weak, the handset increases its radiation level to compensate.
The levels of RF radiation from the handset, to which your head is
exposed, are around 100 to 1,000 times more intense than exposure from base
stations.
