Telecommunications

With digital devices powering every aspect of life and business, telecommunications providers are going neck and neck to provide faster internet speeds at scale―using fiber technology as a linchpin.This post was originally published on this […]

Wireless power transfer (WPT) systems transmit electrical energy from a power source to a load without physical connectors or wires, using electromagnetic fields. This idea goes as far back as the 1890s, when Nikola Tesla […]

Researchers at EPFL and Harvard University have engineered a chip that can convert between electromagnetic pulses in the terahertz and optical ranges on the same device. Their integrated design could enable the development of devices […]

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 […]

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.
