The first commercially operated wireless telephone networks are referred to as 1G and used analogue network technologies. These networks are made up of many cells, each with its own base station, which connects to the terrestrial phone network. The base stations allow connections being handed over from one cell to the next. Hence the used devices are also named cell phones. Without this cell network structure mobile phone users would not be able to travel while calling.
