Analog repeaters dramatically enhance millimeter-wave (mmWave) coverage in mobile networks by overcoming signal blockage, report researchers from Science Tokyo. As demonstrated in a field experiment ...

Repeaters were spaced every 50 km or so along the cable, housed in long, pressure-rated housings that created bulges in the slim cable, but were still compatible with the cable-laying gear.

Passive Repeaters for Microwave Links are a way of reflecting RF signals along a desired path. They are less and less common, but Valmont still offers to build . I suspect not many are built today, ...

What are quantum repeaters, and how do they work? This explainer lays what these devices do, their role in entanglement swapping, and how the Q-NEXT quantum center is advancing the technology.

APRS Cave-Link uses the amateur radio’s Automatic Packet Reporting System (APRS) inside caves to get their position data (and other messages) out. Imagine that you’re coordinating a lar… ...

(Courtesy: Wang Guoyan and Ma Yanbing) Quantum repeaters that can store multiplexed signals; provide heralded signals of entanglement; and operate at telecommunications wavelengths have been developed ...

“There are ideas for how to take quantum repeaters and parallelize them to provide very high connectivity between quantum computers,” says Oskar Painter, director of quantum hardware at AWS.
