The Telecommunications industry covers occupations in voice (telephony), and data communications. This includes landline (copper cable & fibre optic), wireless (radio from HF to microwave), and satellite systems.

Trends to a more connected society is seeing an increasing demand for more sophisticated telecommunications, not only in the cities but also in rural and remote areas.

This demand, and the recent focus of enabling computers to communicate, has lead to a convergence of technologies, particularly in the areas of computing, multimedia and Information technology (IT).

The telecommunications industry is a service industry to all other industries.
