Cell phone networks

Extensive cell phone networks, uniform wireless networking standards and powerful cell phones revolutionise telephony. However, users can also easily be monitored.

There are several reasons for the rapid spread of mobile telephony. As less transmission power is required for making calls, power consumption is reduced. The size of the rechargeable batteries for the phones can be reduced, thereby also minimizing the weight of the devices themselves. Furthermore, area-wide cell phone networks are set up in Europe from 1985 onwards. Initially, these networks are operated by national postal service providers, but private operators soon follow suit. In the following years, all networks agree on using the common standard GSM (Global System for Mobile Communication) and are integrated into a pan-European network.

A cell phone network consists of numerous closely aligned cells with base stations which continuously receive radio signals from all cell phone transmissions in their respective area. The locations of all participants are stored in a central computer. A call is transmitted from cell to cell up to the cell of the selected conversation partner. However, the mobility offered by cell phones also has a downside, as the system enables the surveillance of its participants.
