Telecommunication Networks Construction
In the past people communicated with each other making use of smoke signals, fire, flags or beacons. These have nowadays been replaced by telephone, radio, TV and computer.
To keep in touch with the world, you need the relevant networks and connections in your home or office. Specialised companies design and build telecommunication networks: automatic exchange and mobile telephone systems, cable and satellite TV, computer networks, Internet. Some of them also design fire safety and security systems.
Most providers also maintain and repair their telecommunication systems. Take note of your provider’s emergency telephone number.
