Low-orbit satellites could soon offer millions of people worldwide access to high-speed communications, but the satellites’ potential has been stymied by a technological limitation—their antenna arrays can only manage one user at a time.This post […]
High-precision positioning in urban areas faces obstacles such as frequent signal blockages and interference from buildings, which compromise the performance of Global Navigation Satellite System (GNSS)-based Real-Time Kinematic (RTK) systems. These conditions lead to reduced […]
A new, cheap, easily manufactured device could lead to improved satellite communication, high speed data transmission, and remote sensing, scientists say.This post was originally published on this site.
Verizon is buying Frontier Communications in a $20 billion deal to strengthen its fiber network.This post was originally published on this site.
Communication satellites and flying antenna platforms can contribute to the comprehensive and resilient operation of global mobile networks of the fifth and sixth generation (5G, 6G). However, as large parts of the millimeter wave (mmW) […]
In a new paper published in Light: Science & Application, a team of scientists, led by Professor Khaled Salama from King Abdullah University of Science and Technology, and co-workers have developed a reconfigurable simultaneous lightwave […]
Smart antennas have garnered significant attention for their ability to enable both communication and perception functions simultaneously; however, they commonly come with complicated controls and a high cost.This post was originally published on this site.
Infrared light cannot be seen, but it can be felt as heat. Lying beyond the red color in the electromagnetic spectrum, it is used by animals to detect prey in the dark and in night […]
Global Navigation Satellite System (GNSS) accuracy is crucial for precise applications, yet regional networks often face challenges in maintaining this precision. Integrating data from Low Earth Orbit (LEO) satellites with ground stations offers a promising […]
About one-third of the global population, around 3 billion people, don’t have access to the internet or have poor connections because of infrastructure limitations, economic disparities and geographic isolation.This post was originally published on this […]
