Device communication may also refer to how the hardware devices in a message exchange system enable the message exchange. For example, when browsing the Internet, a number of different devices work in tandem to deliver the message through the internet traffic—routers, switches and network adapters, which on a hardware level send and receive ...
Node D is unaware of the ongoing data transfer between node A and node B. Node D has data to send to node C, which is in the transmission range of node B. D initiates the process by sending an RTS frame to node C. Node C has already deferred its transmission until the completion of the current data transfer between node A and node B (to avoid co-channel interference at node B).
Originally the terms were used interchangeably but nowadays most radio users use the term "jamming" to describe the deliberate use of radio noise or signals in an attempt to disrupt communications (or prevent listening to broadcasts) whereas the term "interference" is used to describe unintentional forms of disruption (which are far more common ...

SCIP was designed by the Department of Defense Digital Voice Processor Consortium (DDVPC) in cooperation with the U.S. National Security Agency and is intended to solve problems with earlier NSA encryption systems for voice, including STU-III and Secure Terminal Equipment (STE) which made assumptions about the underlying communication systems ...
Anti-access/area denial (or A2/AD) is a military strategy to control access to and within an operating environment. [2] In an early definition, anti-access refers to those actions and capabilities, usually long-range, designed to prevent an opposing force from entering an operational area.
Allied Communication Procedures is the set of manuals and supplements published by the Combined Communications Electronics Board that prescribe the methods and standards to be used while conducting visual, audible, radiotelegraph, and radiotelephone communications within NATO member nations.
Type B cards use ASK with NRZ coding for reader-to-tag communication and binary phase-shift keying (BPSK) with NRZ-L encoding for tag-to-reader communication. [ 5 ] [ 6 ] Both Type A and Type B cards only allow half duplex communication with a 106 kbit per second data rate in each direction.
