What Is a Telecommunications Network?
A telecommunications network is a collection of interconnected networks of devices, transmission media and communications equipment that carries voice, data, video and internet traffic between users and devices across local, national and international distances.
Put frankly, telecommunications networks are the systems of developing communications for a person or an organization. All communication, whether a phone call, a text message, a web cast, a visit to a web site, or a cloud based application, passes through a telecommunications network.

Network Communication Steps
- Data is generated by a device.
- Information is converted into digital signals.
- Signals travel through wired or wireless infrastructure.
- Routers and switches determine the best path.
- The destination device receives and decodes the information.
This is done in a matter of milliseconds between international networks.
