Cloud computing has burst recently into technology and business scene promising great technical and economic advantages, like offering On-demand provisioning of computer services, improved flexibility and scalability as well as reducing costs. Another attractive point of the cloud is its…
Optical communications make use of light waves, very high frequency (100 terahertz) electromagnetic waves, for information transmission. Modern optical communications were begun in the 1960s, when lasers were invented as a coherent light source. Since then, the rapid development of…
Communications is vital for War fighters to exchange voice and data, command and control and situational awareness data and video. The vision of Communications area is to provide reliable communication from anywhere to everywhere from war fighters to supreme commander…
Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band…
Chinese military has been engaged in comprehensive modernization of its air, naval, and ground forces, while incorporating a variety of anti-access/area denial (A2/AD) systems and capabilities. “To operate against adversaries with “anti-access / area denial” capabilities the U.S. needs to…
Underwater communication is vital for undersea exploitation and modern communication. Conventional ways which employ acoustical technique for underwater communication have their drawbacks including high path loss, narrow bandwidth, high bit error rate, among which unconditional security is more demanding due to commercial and…
As warfighting has progressively become more sophisticated, involving larger forces, encompassing greater areas, and containing many new and more lethal weapon systems, the communication systems supporting the command and control functions have undergone a similar evolution. Communication methods have evolved…
Successful military operations depend upon freedom of action in the warfighting domains of air, space, ground, sea, and cyberspace. Today, effective command and control and situational awareness depend upon radio communications and sensors. Domination of the electromagnetic spectrum (EMS) enables…
Whether in the field of battle, search-and-rescue or humanitarian aid efforts, the ability to share real-time, networked information between ground, sea and airborne forces is rapidly becoming the defining factor in a mission’s success. However modern satellite and other communications…
The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights,…
