Seems like an easy enough question. However, in this case, context is everything. Telecommunications:           1. The art and science of “communicating” over a distance by telephone, telegraph and/or radio. The transmission, reception and the switching of signals, such as electrical or optical, by wire, fibre, or electromagnetic means.           2. A fancy word for “telephony,” which it replaced and which many thought meant only analog voice, but didn’t. Infrastructure:            1. A collection of those telecommunications components, excluding equipment, that together provide the basic support for the distribution of all information within a building or campus. Courtesy of Newton’s Telecom Dictionary 20th edition by Harry Newton This may seem like a plausible and even accurate definition, however, TI Telecom has come to understand the term to mean: The collection of knowledge and the ability to understand and implement that knowledge to exceed client expectations.
