Challenges and Opportunities for Simultaneous Multi-functional Networks in the UHF Bands
Xavier Vilajosana, Guillem Boquet, Joan Melià +3
Multi-functional wireless networks are rapidly evolving and aspire to become a promising attribute of the upcoming 6G networks. Enabling multiple simultaneous networking functions…
LR-FHSS: Overview and Performance Analysis
Guillem Boquet, Pere Tuset-Peiro, Ferran Adelantado +2
Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) is the new physical layer designed to address extremely long-range and large-scale communication scenarios, such as satellite…
Debunking Wireless Sensor Networks Myths
Borja Martinez, Cristina Cano, Xavier Vilajosana
In this article we revisit Wireless Sensor Networks from a contemporary perspective, after the surge of the Internet of Things. First, we analyze the evolution of distributed monit…
Exploiting the Solar Energy Surplus for Edge Computing
Borja Martinez, Xavier Vilajosana
In the context of the global energy ecosystem transformation, we introduce a new approach to reduce the carbon emissions of the cloud-computing sector and, at the same time, foster…
Experimental Interference Robustness Evaluation of IEEE 802.15.4-2015 OQPSK-DSSS and SUN-OFDM Physical Layers
Pere Tuset-Peiró, Francisco Vázquez-Gallego, Jonathan Muñoz +3
In this paper, we experimentally evaluate and compare the robustness against interference of the OQPSK-DSSS (Offset Quadrature Phase Shift Keying - Direct Sequence Spread Spectrum)…
Experimental Clock Calibration\\on a Crystal-Free Mote-on-a-Chip
Ioana Suciu, Filip Maksimovic, David Burnett +6
The elimination of the off-chip frequency reference, typically a crystal oscillator, would bring important benefits in terms of size, price and energy efficiency to IEEE802.15.4 co…
Authenticated Preambles for Denial of Service Mitigation in LPWANs
Ioana Suciu, Jose Carlos Pacho, Andrea Bartoli +1
In this article we introduce authentication preambles as a mechanism to mitigate battery exhaustion attacks in LPWAN networks. We focus on the LoRaWAN technology as an exponent of…
A Channel Measurement Campaign for mmWave Communication in Industrial Settings
Adrian Loch, Cristina Cano, Gek Hong +3
Industry 4.0 relies heavily on wireless technologies. Energy efficiency and device cost have played a significant role in the initial design of such wireless systems for industry a…
Aggressive Fragmentation Strategy for Enhanced Network Performance in Dense LPWANs
Ioana Suciu, Xavier Vilajosana, Ferran Adelantado
Low Power Wide Area Networks (LPWANs) are gaining ground in the IoT landscape and, in particular, for Industrial IoT applications. However, given the strict duty cycle restrictions…
Exploring the Performance Boundaries of NB-IoT
Borja Martinez, Ferran Adelantado, Andrea Bartoli +1
NarrowBand-IoT has just joined the LPWAN community. Unlike most of its competitors, NB-IoT did not emerge from a blank slate. Indeed, it is closely linked to LTE, from which it inh…
X-ray Luminosity Function of Quasars at 3<z<5 from XMM-Newton Serendipitous Survey Data
G. A. Khorunzhev, S. Yu. Sazonov, R. A. Burenin
The X-ray luminosity function of distant (3<z<5.1) unabsorbed quasars has been measured. A sample of distant high-luminosity quasars ($10^{45} \leq L_{{\rm X},2-10} < 7.5 \times 10…
The Wireless Technology Landscape in the Manufacturing Industry: A Reality Check
Xavier Vilajosana, Cristina Cano, Borja Martinez +3
An upcoming industrial IoT revolution, supposedly led by the introduction of embedded sensing and computing, seamless communication and massive data analytics within industrial pro…
An Analysis of Packet Fragmentation Impact in LPWAN
Ioana Suciu, Xavier Vilajosana, Ferran Adelantado
Packet fragmentation has mostly been addressed in the literature when referring to splitting data that does not fit a frame. It has received attention in the IoT community after th…
Understanding the limits of LoRaWAN
Ferran Adelantado, Xavier Vilajosana, Pere Tuset-Peiro +3
The quick proliferation of LPWAN networks, being LoRaWAN one of the most adopted, raised the interest of the industry, network operators and facilitated the development of novel se…
