From fixed cables to satellites

In the early years of telecommunications, the only way of linking one telephone with another was by fixed cables. Links between continents relied on cables under the sea. The invitation of the radio brought the first wireless communications, but because the surface of the earth is curved these signals could not travel far. Satellites changed everything. They sit at an exact height above the earth’s equator and they rotate at the same speed as the earth spins. This means that they stay in a fixed position. Telephone signals can be sent to the satellites and bounced back to earth. Everyone on the planet can be covered by only five or six satellites, except for the poles and surrounding areas, which are out of their range.
