A federal multibillion-dollar effort that subsidized internet service providers to bring broadband to underserved areas has provided much-needed high-speed internet to some of the country’s remote and rural areas. However, according to UC Santa Barbara […]

As someone that has always lived in the UK countryside, I am no stranger to the glory of a dark star-filled sky. Sadly, 60% of the world’s population has already lost access to the night […]

A new system aimed at improving the monitoring and detection of forest fires through advanced real-time image processing is reported in the International Journal of Information and Communication Technology. The work could lead to faster […]

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 article […]

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 […]
