Telecom industry has been observing a technologically evolving phase in the recent years.
Technology evolution challenges both the Telecom Equipment vendors and Service Providers,
serving both wire-line and wireless solution spaces.
Telecom sector, like any other industrial sector has gone through many phases of growth and
diversification. Starting from telegraphic and telephonic systems in the 19th century, the field
of telephonic communication has now expanded to make use of advanced technologies like GSM,
CDMA, and WLL to the great 3G Technology in mobile phones. Day by day the companies and the
industry as an entirety are putting in their resources and best efforts to improve the
telecommunication technology to provide with the maximum benefits to their customers.
The telecommunications industry is at the forefront of the information age?delivering voice, data, graphics and video at ever increasing speeds and in an increasing number of ways. Whereas wire-line telephone communication was once the primary service of the industry, wireless communication services and cable and satellite program distribution make up an increasing share of the industry.
The largest sector of the telecommunications industry continues to be made up of wired telecommunications carriers. Establishments in this sector mainly provide telephone service via wires and cables that connect customers? premises to central offices maintained by telecommunications companies. While voice used to be the main type of data transmitted over the wires, wired telecommunications service now includes the transmission of all types of graphic, video, and electronic data mainly over the Internet.
These new services have been made possible through the use of digital technologies that provide much more efficient use of the telecommunications networks. One major technology breaks digital signals into packets during transmission. Networks of computerized switching equipment, called packet switched networks, route the packets. Packets may take separate paths to their destination and may share the paths with packets from other users. At the destination, the packets are reassembled, and the transmission is complete.
