The Telecommunication Studies Group is a federation of faculty and researchers at the Annenberg School for Communication at the University of Southern California whose research focuses on telecommunication technology. This research seeks to understand how societal, economic, social, management, technological, and policy factors shape telecommunication, information, and media technologies, and their implications.

Telecommunication is the assisted transmission of signals over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags, or heliograph. In modern times, telecommunication typically involves the use of electronic transmitters such as the telephone, television, radio or computer. Early inventors in the field of telecommunication include Alexander Graham Bell, Guglielmo Marconi and John Logie Baird. Telecommunication is an important part of the world economy and the telecommunication industry's revenue has been placed at just under 3 percent of the gross world product.

Telecommunication equipment relies on all of the individual electrical components to interact successfully. When one part is wrong all of the telecommunication equipment will suffer. When there is a problem with telecommunication equipment it is important for the technician to pinpoint the area that is causing the issue. New telecommunication equipment is built so that individual parts can be easily removed and replaced. Older telecommunications equipment offer a little more of a challenge. Kings Electronics ... offer crimpers and other hand tools to help repair telecommunication equipment.

In modern times, this process typically involves the sending ofelectromagnetic waves by electronic transmitters, but in earlier times telecommunication may have involved the use ofsmoke signals,drumsorsemaphoreorheliograph. Today, telecommunication is widespread and devices that assist the process, such as thetelevision,radioandtelephone, are common in many parts of the world. There are ... many networks that connect these devices, includingcomputer networks,public telephone networks,radio networksandtelevision networks. Computer communication across theInternetis one of many examples of telecommunication.
