Every mobile phone is first and foremost a transducer, which means that it will first capture the voice of its user and then transform it into digital data. This information is relayed to the central office by a dense network of telephone antennas and then reaches the recipient.
The real complexity lies in managing the relay system. The antennas can only serve about 60 users, which is relatively few compared to the number of simultaneous calls that can be made in the effective area of an antenna. To do this, operators sometimes pool their antennas in order to densify the network and thus provide better coverage.
