Fiber Optics transmission system and component technologies for Rising Internet traffic

July 1, 2021 Comm. & NW, Photonics Comments Off on Fiber Optics transmission system and component technologies for Rising Internet traffic

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 photonic technologies has made possible optical communication links with a …

Networking technologies for integration of Quantum cryptography (QKD) on commercial optical networks essential for global scale Quantum Key Distribution Networks

June 29, 2021 Comm. & NW, Photonics, Quantum Comments Off on Networking technologies for integration of Quantum cryptography (QKD) on commercial optical networks essential for global scale Quantum Key Distribution Networks

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that if Eve attempts to intercept and measure Alice’s quantum transmissions, her …

Next generation Military Communications technologies enabling high-throughput mobile, secure, survivable, seamless, in congested and contested environments

June 23, 2021 Comm. & NW, Soldier Comments Off on Next generation Military Communications technologies enabling high-throughput mobile, secure, survivable, seamless, in congested and contested environments

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 with demanded rate and least latency by exploiting complete electromagnetic …

Extremely Low Frequency and Very Low Frequency (ELF/VLF ) Communications for Underground, Underwater, and Hypersonic Flight

June 23, 2021 Comm. & NW, Electronics & EW Comments Off on Extremely Low Frequency and Very Low Frequency (ELF/VLF ) Communications for Underground, Underwater, and Hypersonic Flight

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 signals have large EM wavelengths that can penetrate the plasma …

DARPA’s DyNAMO and C2E demonstrated Secure, Jam Resistant and Adaptable Airborne Networks for Collaborative team of Manned & Unmanned Platforms

June 21, 2021 Air Force, Comm. & NW Comments Off on DARPA’s DyNAMO and C2E demonstrated Secure, Jam Resistant and Adaptable Airborne Networks for Collaborative team of Manned & Unmanned Platforms

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 disperse its forces, disaggregate its capabilities, confuse enemy sensors through …

Ultra secure, Quantum Communications using Quantum Key Cryptography (QKD) for Underwater Vehicles and Submarines critical to maintain nuclear deterrence capability

June 16, 2021 Comm. & NW, Navy, Quantum Comments Off on Ultra secure, Quantum Communications using Quantum Key Cryptography (QKD) for Underwater Vehicles and Submarines critical to maintain nuclear deterrence capability

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 secure interest. Submarine communications have always been a challenge …

Meteor scatter or Meteor burst communications (MBC) can provide anti-jamming, nuclear survivable backup to satellite communications even in Arctic Region

May 31, 2021 Comm. & NW, Space Comments Off on Meteor scatter or Meteor burst communications (MBC) can provide anti-jamming, nuclear survivable backup to satellite communications even in Arctic Region

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 to the capability of rapidly establishing worldwide “real time” communications …

DOD regards Electromagnetic Spectrum (EMS) as a critical battlespace in its own right, and launch it’s Electromagnetic Spectrum Dominance Strategy

May 16, 2021 Comm. & NW, Doctrine & Strategy, Electronics & EW Comments Off on DOD regards Electromagnetic Spectrum (EMS) as a critical battlespace in its own right, and launch it’s Electromagnetic Spectrum Dominance Strategy

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 joint force commanders to gain tactical, operational, and strategic advantage …
