…measurement campaign conducted over three months in the city of Brno, Czech Republic, we assessed the communication performance and the radio channel properties in 311 different test locations. We observed…
…of both the proposed energy conversion cycles is compared with that of the Olsen cycle. The electro–optic and thermo–electro–optic cycles are found to harvest 7–10 times more energy than the…
…devices. Herein, we analyze Selection Combining (SC) and Switch and Stay Combining (SSC) diversity schemes as plausible solutions for enabling ultra-reliable low-latency downlink communications to low-cost IoT devices. We demonstrate…
…single‐material energy harvesting/sensing device is fabricated using a (K0.5Na0.5)NbO3‐Ba(Ni0.5Nb0.5)O3–Δ (KNBNNO) ceramic as the sole energy‐conversion component. This single‐material component is able simultaneously to harvest or sense solar (visible light), thermal…
…experiments are conducted with different parameters such as SNR, error variance, and power allocation to show their impact on the CoMP method. The results show that CoMP NOMA outperforms the…
…and application distribution. In this study, we design, implement, and evaluate a mobile sensing framework for iOS, namely AWARE-iOS, which is an iOS version of the AWARE Framework. Our performance…
In this paper, a differentially-driven wideband multiple-feed on-chip antenna design in 0.13 μm SiGe technology is proposed for millimeter-wave power combining applications. The in-antenna power combining concept is achieved by…
In this paper, the depolarization effect due to the electromagnetic wave diffraction from the rooftop wedge of a building at 1.575 GHz frequency is presented. Diffraction measurement was performed using…
The concept of interactive visible light communications (iVLC) is introduced and discussed in this paper. iVLC exploits a matrix of solid-state light luminaries in multiple ways, namely providing lighting and…
…companies traditionally have their own information systems that don’t communicate with each other. In addition, there is official information, customs clearance, etc.,” Ahokangas says. “When these are combined with digitalisation,…
