LED lights point shoppers in the right direction

Looking for an item in a large department store or mall can be like searching for a needle in a haystack, but that could change thanks to a hybrid location-identification system that uses radio frequency transmitters and ...

LED lights build communication network

(PhysOrg.com) -- Imagine a world where bright, energy-sipping, cheap, durable LEDs light the world. A world where if you have enough light to see, you are connected. The University of California, Riverside will lead a multi-campus ...

NASA's new experimental antenna tracks deep space laser

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 ...

HD video from the moon in near real time

A new optical modem, capable of sending high-definition quality video significantly faster than standard radio frequency systems, is being developed for NASA's Orion spacecraft. The hardware, offered by LGS Innovations, is ...

Bursting the clouds for better communication

We live in an age of long-range information transmitted either by underground optical fibre or by radio satellites. But the throughput today is so great that radio frequency is no longer enough in itself. Research is turning ...
