July 2020: NB-IoT!

Our paper “Coverage and Deployment Analysis of Narrowband Internet of Things in the Wild” has been accepted for publication in IEEE Communications Magazine (Internet of Things and Sensor Networks Series). A preprint version is available on ArXiv here.

The paper presents a large scale measurement campaign and empirical analysis of NB-IoT on operational networks, and discloses valuable insights in terms of deployment strategies and radio coverage performance. The reported results also serve as examples showing the potential usage of the collected dataset, which we make open-source along with a lightweight data visualization platform.

Supplementary materials, visualization platform, and open-source data are available here! Take a look!

Jan-Apr 2019: Papers, papers

Our paper “ViFi: Virtual Fingerprinting WiFi-based Indoor Positioning via Multi-Wall Multi-Floor Propagation Model” has been accepted for publication in IEEE Transactions on Mobile Computing. An early access version is already available on ieeexplore (here).
The paper introduces ViFi, an indoor positioning system that relies on WiFi Received Signal Strength (RSS) prediction based on Multi-Wall Multi-Floor (MWMF) propagation model, and allows a significant reduction in the number of measurements to be collected in traditional fingerprinting system, while achieving the same accuracy.

Our paper “Two-tier Architecture for NB-IoT: Improving Coverage and Load Balancing” has been presented at 26th International Conference on Telecommunications (ICT’19), Hanoi, Vietnam, Apr. 8-10.
The paper analyzes by simulation the performance of NB-IoT in a HetNets system, taking into account its specific features, and how they combine with a multi-tier architecture. Results show that the use of a 2-tier dedicated architecture nicely combines with the NB-IoT Coverage Enhancement techniques, boosting system efficiency and coverage, while also triggering improved load balancing.
