An IoT system for a smart campus: Challenges and solutions illustrated over several real-world use cases
Tomás Domínguez-Bolaño, Valentín Barral, Carlos J. Escudero +1
This article discusses the development of an IoT system for monitoring and controlling various devices and systems from different vendors. The authors considered key challenges in…
Time-modulated phased array controlled with nonideal bipolar squared periodic sequences
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
Bipolar (+/-1) sequences with no zero state suit particularly well for safeguarding the switched feeding network efficiency when applied to time-modulated arrays (TMAs). During the…
Unleashing the Potential of LTE for Next Generation Railway Communications
P. Fraga-Lamas, J. Rodríguez-Piñeiro, J. A. García-Naya +1
In an increasingly demanding marketplace that will put great strain on railway services, research on broadband wireless communication must continue to strive for improvement. Based…
Direct Antenna Frequency-Hopped M-FSK Modulation With Time-Modulated Arrays
Roberto Maneiro-Catoira, Julio Brégains, José A. García-Naya +1
We present an innovative approach that simultaneously enables direct antenna frequency-hopped M-ary frequency shift keying (DAFH-MFSK) modulation and beamsteering through the use o…
Fine Time Measurement for the Internet of Things: A Practical Approach Using ESP32
V. Barral Vales, O. C. Fernández, T. Domínguez-Bolaño +2
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 ser…
Time-modulated multibeam phased arrays with periodic Nyquist pulses
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
We present a single sideband time-modulated multibeam phased array governed by periodic Nyquist pulsed signals. A Nyquist pulse is a physically realizable approach to the ideal sin…
