One year after unveiling a first-of-its-kind “microwave brain” microchip capable of computing on ultrafast data and wireless signals, researchers from the Cornell Duffield College of Engineering have shown how the chip can encode information into […]
Mobile phones today handle far more wireless signals and services than earlier generations. The same is true of the sophisticated equipment behind mobile networks, such as base stations, and emerging technologies such as self-driving cars. […]
Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a novel chip architecture that enables the miniature acoustic devices inside smartphones to withstand more than 12 times higher power loads while […]
In a new study presented at the IEEE International Conference on Communications in Glasgow, researchers from Queen Mary University of London and partners from around the world showcased the system, called Joint DAS and GNSS […]
Princeton University researchers have found a way to extend the near-field range for sub-terahertz wireless systems using off-the-shelf hardware. By using multiple synchronized arrays, the team achieved advanced near-field capabilities that were previously thought to […]
FPAs are image sensors that convert infrared light into electrical signals to produce real-time thermal images and are widely used in applications such as surveillance, astronomy and industrial monitoring. Advances in cryogenic FPAs have enabled […]
Modern wireless communication systems prefer higher frequencies to meet the growing demand for faster data transfer. The 300-GHz band, which lies near the lower end of the terahertz range, is a promising candidate for future […]
Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite communications (SATCOM) focus on securing reliable communications channels against adversaries in contested environments. In support of this mission, a team from MIT […]
Since 2019, GPS signals across Europe, Greenland and Canada have experienced a huge spike in sudden, widespread signal blackouts. These have resulted in disruptions and degraded performance in navigation systems that airplanes and ships rely […]
Basements, tunnels, large buildings—a weak Wi-Fi or mobile signal in these hard-to-reach places is frustrating. The usual solution is to add more electronics like routers, repeaters and base stations. Yet, as we move towards a […]
