A quantum sensor has been developed that can analyse the full spectrum of radio frequencies, which could enable new options for military communication. Researchers for the US army built the quantum sensor, which can sample from zero frequency up to 20GHz, detecting AM and FM radio, Bluetooth, Wi-Fi and other communication signals along the way. … Read more
The pandemic has thrown open fresh challenges and unknown opportunities. Jobs of the future will never be the same. The lockdown has unlocked new unchartered avenues for the e-commerce industry, which has become India’s fastest-growing digital business with players like Amazon India’s Flex Delivery programme expanding to 35 cities. This initiative has opened up part-time job … Read more
Optical fibres, the cornerstone technology for high-speed data transfer, can be given a significant performance boost by hollowing out their centre, researchers from Southampton University have discovered. Optical fibres, which are made of silica glass, have long been the transmission medium of choice for high-speed optical communications as well as for other uses such as … Read more
After months of extensive upgrades to its Deep Space Network dish in Australia, Nasa has made contact once more with the Voyager 2 probe, which had been flying solo since March. The Voyager 2 probe, which last year became only the second man-made object to leave the solar system after its sibling Voyager 1, can now only … Read more
Astronauts will soon be able to send high-speed data transmissions from space with the construction of a new optical communications station in Western Australia. The ground station has the potential to receive high-definition video footage in real time and will probably be how video from Nasa’s next Artemis mission to the Moon in 2024 is beamed back down … Read more
