Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles. In modern times, telecommunications involves the use of electrical devices such as the telegraph, telephone, radio, and microwave communications. Communication channels make use of fiber optics and their associated electronics, orbiting satellites, and the Internet. Modern telecommunications industry players produce communication equipment and deliver a set of voice, data, and broadband services using wireline or wired infrastructure of cables, networks, servers, computers, and satellites.
In a telephone network, the caller is connected to the person he wants to talk to by switches at various telephone exchanges. The switches form an electrical connection between the two users and the setting of these switches is determined electronically when the caller dials the number. The fixed-line telephones in most residential homes are analog however increasingly telephone service providers are converting the signals to digital for transmission before converting them back to analog for the reception. This enables digitized voice data traveling side-by-side with data from the Internet.

This industry is highly sensitive to the slightest change in regulatory, technological, and economic factors and has its own share of challenges largely stemming from these factors. With wireless and broadband providing the needed momentum to their growth, the industry players adopt unique strategies to overcome these challenges and move forward to connect people to people and organizations.
