Multiband Massive IoT: A Learning Approach to Infrastructure Deployment
Enes Krijestorac, Ghaith Hattab, Petar Popovski +1
We consider a novel ultra-narrowband (UNB) low-power wide-area network (LPWAN) architecture design for uplink transmission of a massive number of Internet of Things (IoT) devices o…
Band Assignment in Ultra-Narrowband (UNB) Systems for Massive IoT Access
Enes Krijestorac, Ghaith Hattab, Petar Popovski +1
In this work, we consider a novel type of Internet of Things (IoT) ultra-narrowband (UNB) network architecture that involves multiple multiplexing bands or channels for uplink tran…
Spectrum Sharing for Massive Access in Ultra-Narrowband IoT Systems
Ghaith Hattab, Petar Popovski, Danijela Cabric
Ultra-narrowband (UNB) communications has become a signature feature for many emerging low-power wide-area (LPWA) networks. Specifically, using extremely narrowband signals helps t…
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…
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…
Uplink Interference Mitigation Techniques for Coexistence of 5G mmWave Users with Incumbents at 70 and 80 GHz
Ghaith Hattab, Eugene Visotsky, Mark Cudak +1
The millimeter wave spectra at 71-76GHz (70GHz) and 81-86GHz (80GHz) have the potential to endow fifth-generation new radio (5G-NR) with mobile connectivity at gigabit rates. Howev…
