When you think about location data on your mobile phone, tablet or laptop, what comes to mind? Mailing addresses? Postal codes? These data indicate where you live, where you work, and the places you visit.This […]

Imagine sitting in a packed stadium for a pivotal football game—tens of thousands of people are using mobile phones at the same time, perhaps video chatting with friends or posting photos on social media. The […]

EPFL researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with […]

Network-assisted full-duplex (NAFD) systems enable uplink and downlink communications within the same time-frequency resources, so as to avoid the overhead of switching uplink/downlink modes. However, as the number of users and access points (APs) proliferated, […]

Drones are operating increasingly in areas out of sight of the person controlling them. However, conventional remote controls have a limited range, which makes them unsuitable for these flights. On the other hand, simple mobile […]

Imagine being in a boat miles from shore when the engine fails, or getting lost in a remote spot while hiking in the Rocky Mountains. Having a beacon or transmitter that sends a distress signal […]

Our first responders have spoken. An extensive research project conducted by experts at the National Institute of Standards and Technology (NIST) reveals what our country’s police, fire, emergency medical and 911 dispatch responders think about […]

Incidents such as the 2021 Colonial Pipeline hack and ransomware attacks on U.S. colleges and universities illustrate the importance of robust cybersecurity measures that protect the technologies and services that people rely on for everything […]

A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that connects a resistor to […]

Sophisticated antenna arrays paired with high-frequency wireless chips act like superpowers for modern electronics, boosting everything from sensing to security to data processing. In his lab at Princeton, Kaushik Sengupta is working to expand those […]
