Almost 200 years back, in the 1830s, the first telecom technology was invented – the telegraph. Over a period, newer devices came in – conventional telephones, radio, TV, computers, and finally mobile phones. Not only in the end-user device but also infrastructure-wise there has been a change – till about a few years telecom was about lots of wires and physical networks. Now, smart technology is wireless and digital; and that is the basis of all forms of communication today.
Telecom systems in the modern world involve the transmission of huge volumes of information related to voice and data signals. It also involves transmitting radio and television signals. By digitizing telecom transmissions, reliability is boosted at lower costs.
India is one of the largest consumers of data in the world. Globally, the country is ranked at number two in terms of internet subscribers (1.20 billion) and telecom subscribers. Today, India is ranked at number two for the second-highest market for apps download. Following the Government’s Digital India announcement in 2018, the telecom sector has attracted billions in investments and is expected to generate at least 4 million jobs in the country.
On its part governments across states and Union Territories and even at the Centre have spent thousands of crores to fortify the telecom infrastructure in the country. There are major developments happening in the telecom industry, both by the government and private companies because India is a lucrative market. The revenues are expected to grow with the sale of telecom equipment and the internet subscribers are expected to double in the next one year; while the Internet Protocol traffic is forecasted to grow at least four times by 2021.
