Dual-Beam Steerable TMAs Combining AM and PM Switched Time-Modulation
(MDPI, 2022)
[Abstract] Wireless sensor networks (WSN) are increasingly requiring directional antennas that not only provide higher capacity, security, transmission range or robustness against interference, but also contribute with ...
An overview of IoT architectures, technologies, and existing open-source projects
(Elsevier, 2022-11)
[Abstract]: Today’s needs for monitoring and control of different devices in organizations require an Internet of Things (IoT) platform that can integrate heterogeneous elements provided by multiple vendors and using ...
Fine Time Measurement for the Internet of Things: A Practical Approach Using ESP32
(Institute of Electrical and Electronics Engineers Inc. (IEEE), 2022)
[Abstract]: In the world of Internet of Things (IoT), obtaining the physical location of devices has always been a task of great interest for developing increasingly complex location-based services (LBS). That is why in ...
TMA–FDA Range-Angle Beamforming With Periodic Linear-Phase Time-Modulating Waveforms
(Institute of Electrical and Electronics Engineers, 2022)
[Abstract]: Frequency diverse arrays (FDAs) provide range-angle time-invariant transmit–receive beamforming, although a fine focus of their radiation patterns is costly since high-resolution mixers and phase shifters are ...
