Researchers have successfully used a coherent transceiver prototype to detect polarization changes that preceded a cable break in a live network. The work, which is one of the first demonstrations of field-based measurements ...
An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...
Radar altimeters are the sole indicators of altitude above a terrain. Spectrally adjacent 5G cellular bands pose significant risks of jamming altimeters and impacting flight landing and takeoff. As wireless technology expands ...
An avalanche swept up skiers at Lake Tahoe's largest ski resort on Jan. 10, 2024, as a 150-foot-wide sheet of snow slid down a mountain slope into a pile 10 feet deep. One person died in the avalanche, and three others were ...
NASA on Monday announced it had used a state-of-the-art laser communication system on a spaceship 19 million miles (31 million kilometers) away from Earth—to send a high-definition cat video.
Recent advancements in AI and more specifically large language models such as ChatGPT have put a strain on data centers. AI models require huge amounts of data to train, and in order to move data between the processing units ...
In February 2023, researchers from around the country gathered at a NASA-sponsored workshop to discuss the latest developments and a roadmap for a cryobot mission concept to drill through the icy crusts of Europa and Enceladus ...
Optical wireless may no longer have any obstacles. A study by Politecnico di Milano, conducted together with Scuola Superiore Sant'Anna in Pisa, the University of Glasgow and Stanford University, and published in Nature Photonics, ...
DSOC, an experiment that could transform how spacecraft communicate, has achieved "first light," sending data via laser to and from far beyond the moon for the first time.
Slated to launch on Oct. 12 with the Psyche mission, DSOC will demonstrate technologies enabling the agency to transmit higher data rates from deep space.
