The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. LiFi works…
The lifelong human imperative to communicate is so strong that people talk not only to other people but also to their pets, their plants and their computers. Straightforward as that may sound, communication involves several coordinated processes. The speaker puts ideas…
Radio frequency waves (RF) are electromagnetic waves between the frequencies of 3 kilohertz to 300 gigahertz, used in radio, cellphones, wi-fi, radar, GPS, and many other systems. While humans have used RF technology to communicate for over 100 years, no…
Access to spectrum is also critical for future swarm of UAVs, In a vision shared by innovators, entrepreneurs, and planners in both defense and civilian contexts, the skies of the future will be busy with unmanned aerial vehicles (UAVs). Unseen but…
Russia, has displayed jamming and spoofing capabilities in the ongoing conflicts in Ukraine and Syria in the last several years. The use of Russian technology in these conflicts demonstrated that Russia retains advanced electronic warfare capabilities. Russia has deployed…
Modern day radio transmitters and receivers, the devices that uses electromagnetic wave signals to communicate through cellphones, radios and television, seem to be present everywhere. The propagation of these electromagnetic waves has some limitation too, Key among these is that…
The modern battlespace is an irregular, against a tech-enabled enemy, and within urban environments and/or complex terrain. Traditional communications infrastructure like cell phone towers are centralized therefore vulnerable to single point failures such as physical damage to their central server,…
