Telecommunications
Telecommunication, often used in its plural form, is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems are excluded from the field.

Architecture of Radio
The infosphere* relies on an intricate network of signals, wired and wireless, that support it. We are completely surrounded by an invisible system of data cables and radio signals from access points, cell towers and overhead satellites. Our digital lives depend on these very physical systems for communication, observation and navigation.
