How mobile handsets work

When a mobile handset is switched on, it periodically communicates with the antenna which provides coverage in the specific area where they are located. In this way, the mobile phone sends its position to the mobile network so that the user can make or receive a call from any point in the country and at any time.

Each time we make or receive a call using our mobile phone, electromagnetic waves are transmitted from our handset to the closest antenna, in other words the antenna providing us signal coverage. Following that, the antenna dispatches those waves to a digital switching centre and from there to another antenna and then to another mobile phone or fixed phone. If during the call the caller or called subscriber moves, the mobile network transfers the call from one antenna to another, so that the conversation is not interrupted.

A mobile phone works when a base station is located in the area where it is being used.
