mobile telecommunication

The first transmission of spoken word was done using a copper cable. It was conducted by Graham Bell, the inventor of telephone, in 1876. Following that, Giuliemo Marconi built a device that didn’t use cable – it was named the radio.

Wireless communication was utilized in American public services, such as police or fire department. It brought an idea to create telephone systems based on individual frequencies. There was a need to divide the whole land into smaller areas known as cells (that’s why Americans call mobiles – cellphones), which were used by transceivers , that could repetitively use the same frequency.

It took some years before new frequencies were assigned and antennas were set to provide mobile coverage. In the eighties first systems were introduced. Firstly in Europe (Scandinavia) then in the United States, which launched AMPS system. The European version of AMPS was TACS and it was adapted by the United Kingdom and Ireland. In the beginnings all of the system worked individually so they couldn’t communicate between each other. These were the grandfathers of modern mobile communication, which had limited capabilities and were analogue.

In the end of eighties Europe has designed a new communication system. It was a digital system known as GSM (Global System for Mobile communications) which was introduced in 1991. Since then, GSM became a global system used across the world, that allows not only calling but also sending data, such as text messages. To this day mobile communication is based on the GSM standard.

Since then the technology has improved , there were new faster standards introduced that allowed video calls or fast connection to the Internet. The mobile devices became lighter, more efficient and packed with variety of functions that made them something more than simple telephones. Due to the fact of multiple mobile operators functioning in one country, each European country has a huge web of antennas that provide mobile coverage even in the most remote places of Europe.
