Technology firms have apparently suggested placing tracking devices or a microchip under the skin of convicted criminals to monitor them in prison or when they come out, according to a recent report in the Guardian. […]
We wash our hands, sanitize shopping trolleys and wipe down cafe tables. But what about our phones? We touch these devices dozens of times a day, and take them everywhere from the kitchen to the […]
Smartphones must stay connected to mobile networks at all times to function properly. The core component that enables this constant connectivity is the communication modem (baseband) inside the device. KAIST researchers, using their self-developed testing […]
Researchers from IMDEA Networks, in collaboration with Universidad Carlos III de Madrid, IMDEA Software Institute, and the University of Calgary, have conducted the first large-scale study—”Your Signal, Their Data: An Empirical Privacy Analysis of Wireless-scanning […]
Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical near-field antenna range. The 1,260-square-foot indoor range, lined with radio frequency and microwave foam absorbers, is equipped to accurately sample the […]
Researchers from MIT and elsewhere have designed a novel transmitter chip that significantly improves the energy efficiency of wireless communications, which could boost the range and battery life of a connected device.This post was originally […]
Hi-tech surveillance technologies are a double-edged sword. On the one hand, you want sophisticated devices to detect suspicious behavior and alert authorities. But on the other, there is the need to protect individual privacy. Balancing […]
The development of more advanced technologies to process radiofrequency signals could further advance wireless communication, allowing devices connected to the internet to share information with each other faster and while consuming less energy. Currently, radio […]
Up to now, underwater navigation for divers has been limited primarily to orientation at distinctive points or compass navigation. Although there are concepts that, similar to a sonar, are intended to enable position determination using […]
In wireless communication, spectrum—radio frequencies that allow devices to communicate over the air—is king.This post was originally published on this site.
