Distributed Wideband Sensing-based Architecture for Unlicensed Massive IoT Communications
Ghaith Hattab, Danijela Cabric
Providing Internet connectivity to a massive number of Internet-of-things (IoT) objects over the unlicensed spectrum requires: (i) identifying a very large number of narrowband cha…
Distributed Wideband Spatio-Spectral Sensing for Unlicensed Massive IoT Communications
Ghaith Hattab, Danijela Cabric
In this paper, we propose a dynamic spectrum sensing-based architecture to provide connectivity for a massive number of Internet-of-things (IoT) objects over the unlicensed spectru…
Performance Analysis of Uplink Cellular IoT Using Different Deployments of Data Aggregators
Ghaith Hattab, Danijela Cabric
Data aggregation is an effective solution to enable cellular support of Internet-of-things (IoT) communications. Indeed, it helps alleviate channel congestion, reduce the communica…
Spectrum Sharing Protocols based on Ultra-Narrowband Communications for Unlicensed Massive IoT
Ghaith Hattab, Danijela Cabric
Ultra-narrowband (UNB) communications is an emerging paradigm that tackles two challenges to realizing massive Internet-of-things (IoT) connectivity over the unlicensed spectrum: t…
Energy-Efficient Massive IoT Shared Spectrum Access over UAV-enabled Cellular Networks
Ghaith Hattab, Danijela Cabric
Data aggregation has become an emerging paradigm to support massive Internet-of-things (IoT), a new and critical use case for fifth-generation new radio (5G-NR). Indeed, data aggre…
Coexistence of 5G mmWave Users with Incumbent Fixed Stations over 70 and 80 GHz
Ghaith Hattab, Eugene Visotsky, Mark Cudak +1
Millimeter wave spectrum access over the 70GHz and 80GHz is central to unlocking gigabit connectivity and meeting the explosive growth of mobile traffic. A pressing question, howev…
