The mobile telephone

The first text message was sent in England in 1992. The message was "Merry Christmas". In 2011, every second 200,000 text messages were sent globally.

When you call another mobile the call does not go directly between the telephones.  It first connects via a base station to the operator´s centre, which keeps track of all mobiles that may make calls via a base station when someone is called.

The NMT mobile phone system opened in 1981 after an agreement between telecommunications services in Nordic countries. One of the leading companies was Ericsson. In 1991 a system came for the whole of Europe - GSM. The third generation 3G provided a higher transfer capacity. Mobile systems of the future will be integrated with the Internet and other wireless networks.
