Mobile robots used by the military and law enforcement agencies require a robust communications link for successful mission executions. Such mobile robots are increasingly used in life-threatening situations and hazardous environments, rendering a solid communications link to be of vital…
Satellite communication is a technology that is used to transfer the signals from the transmitter to a receiver with the help of satellites. Communications via satellite have the unique characteristic of the ability to cover the globe with a flexibility…
UK Strategic Command is expected to invest £1.5 billion in the next ten years to “build and sustain a ‘digital backbone’ to share and exploit vast amounts of data, through the cloud and secure networks”, according to Defence Secretary Ben…
Adversaries are increasingly utilizing the proliferation of sophisticated commercial communications and information technology (IT) on the battlefield allowing them to leverage advanced wireless technology like 5G and smartphones while actively moving in ground vehicles. They are also able to execute…
An antenna is a device used to propagate, receive, and/or transmit electromagnetic waves which can have information embedded within them. The antenna creates an electromagnetic wave that carries the original embedded sound information through the atmosphere/space around it. An antenna…
Millimeter waves are electromagnetic signals with frequencies ranging from 30 to 300 GHz that correspond to wavelengths of 10 to 1 mm in the free space. Electromagnetic waves in the millimeter-wave band (with frequencies between 30 and 300 GHz, or wavelengths…
DARPA, is proposing a new Mosaic Warfare strategy for evolving multidomain battlefield. Dr. Timothy Grayson, Director of the Strategic Technology Office is advocating for a “system of systems” approach that he’s calling mosaic warfare: the ability to piece together different…
Broadband fiber-optics carry information on pulses of light, at the speed of light, through optical fibers. But the way the light is encoded at one end and processed at the other affects data speeds. Basically, light or any other electromagnetic radiation…
A Content Delivery Network (CDN) is a globally distributed network of web servers or Points of Presence (PoP) whose purpose is to provide faster content delivery. The content is replicated and stored throughout the CDN so the user can access…
U.S. military researchers are asking industry to develop secure radio frequency (RF) transmitter and receiver technologies to enable the next generation of secure military tactical radio systems. Tactical communications is critical requirement of military communications in which information of any…
