Telecommunications networks

 

Telecommonications networks have ben created to make it possible to communicate to all parts of the globe. Huge networks, whose performance is constantly improving have been created, first of all for fixed telephones then for computers and now for mobile telephones.

These consist of routing or transit centres where signals are routed or converted by powerful computers. These centres are linked together by cable networks (either fibre-optic or copper) or microwave radio links (terrestrial or satellite).
