Soldiers can send text, data, voice and video communications beyond their area of operations without worrying that the information will fall into the hands of enemy forces. Soldiers can extend the range of their network in such a manner that communications cannot be jammed, detected, or intercepted. The US Army identifies the SMART-T as the AN ...
The KG-84A is primarily used for point-to-point encrypted communications via landline, microwave, and satellite systems. The KG-84C is an outgrowth of the U.S. Navy high frequency (HF) communications program and supports these needs. The KG-84A and KG-84C are devices that operate in simplex, half-duplex, or full-duplex modes. The KG-84C ...

By the Second World War, radio had become the chief medium of air-to-ground and air-to-air communication. Since then ...
Primarily, Kavach works on the principle of continuous supervision of the movement authority and is designed to maintain train speed within the specified limits and can automatically apply brakes to slow down or to bring the train to a complete standstill, incase the Loco Pilots violates the speed restrictions or fails to act in time to prevent Signal Passed At Danger (SPAD); thereby reducing ...
A new ACD Version-II, now called the Train Collision Avoidance System (TCAS), is under development by The Research Designs and Standards Organisation (RDSO). Unlike ACD, which is more of a distributed system which acts independently, the TCAS will be more of a centralized system where TCAS controls communication between trains and with trains ...
Multifunction Advanced Data Link (MADL) is a fast switching narrow directional communications data link between stealth aircraft. [1] It began as a method to coordinate between F-35 (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capability to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems.
