Transmission is the means by which telephone conversations get from one place to another. Transmission media have evolved over the years in ways that improved quality, removed distance limitations, and increased capacity, in line with the evolution of the predominant medium through multiple transformations. These began with iron wire and have culminated in today’s fiber optic cable. In doing so, telephone service, has become less expensive and more widely available, thus playing an increasingly important role in bringing people together: across town, across continents, and around the world. This article does not cover cellular telephony, which merits its own article.
