telecommunication Telecommunication 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 fe ...

, communications-electronics (C-E) is the specialized field concerned with the use of electronic devices and systems for the acquisition or acceptance, processing, storage, display, analysis, protection, disposition, and transfer of

information Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random ...

. C-E includes the wide range of responsibilities and actions relating to: * Electronic devices and systems used in the transfer of ideas and perceptions; * Electronic sensors and sensory systems used in the acquisition of information devoid of semantic influence; * Electronic devices and systems intended to allow friendly forces to operate in hostile environments and to deny to hostile forces the effective use of electromagnetic resources.

Electronic Communications Equipment

Communication electronics radio equipment has been a rapidly growing industry for more than a century.

in the USA is one of the reasons for the fast growth. Since the invention of the “solid state”

transistor upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch ...

in the 1950s and the TTL ( transistor-transistor logic) that led to the development of the IC ( integrated circuit) in the 1960s the growth in the field of electronics has been phenomenal. As now witnessed in the “radio communications” field. The latest trend is to send conventional LMR (land-mobile-radio) signals over the Internet (

Internet Protocol The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. ...

) this is called RoIP (Radio over Internet Protocol), which is just like VoIP (Voice over Internet Protocol) but uses the radio. By sending signals over the Internet it allows radios to be connected together all over the world. Hence: the “Communications Revolution”.
