Telecommunications

Telecommunications is the sending and reception of information using wired, radio, optical or other electromagnetic systems.

Overview

A digital communication link represents a source as bits and maps them into signals suitable for its channel. A receiver estimates the transmitted data from the received signal. Compression, error-control coding and modulation have different roles; a system may combine them according to its fidelity, data-rate and error requirements.

Why it matters

Telecommunications systems, developing from wired telegraphy to satellite and cellular networks, support long-distance electronic communication. They provide the physical and logical infrastructure for electronic commerce, distributed computing, and global data exchange.
