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…
