درباره شبکه های کاری

The telecommunications industry within the sector of information and communication technology is made up of all Telecommunications/telephone companies and internet service providers and plays the crucial role in the evolution of mobile communications and the information society.

Traditional telephone calls continue to be the industry’s biggest revenue generator, but thanks to advances in network technology, Telecom today is less about voice and increasingly about text (messaging, email) and images (e.g. video streaming). High-speed internet access for computer-based data applications such as broadband information services and interactive entertainment, is pervasive. Digital Subscriber Line (DSL) is the main broadband telecom technology. The fastest growth comes from (value-added) services delivered over mobile networks.
