    Reliable connectivity over large distances is one of the main features characterising Low-Power Wide Area Network (LP-WAN) technologies, with Narrowband Internet of Things (NB-IoT) as the most promising one. The advent of such a family of communication standards has attracted attention of the industry, as excellent coverage of LP-WAN potentially enables new opportunities of automation, for instance remote metering or asset tracking. However, telecommunication standardisation bodies are still lacking accurate models of signal attenuation in deep-indoor environments. This work attempts to address this gap by presenting experimental measurements on NB-IoT deep-indoor signal attenuation. The results indicate the differences in signal propagation between underground and above-ground indoor scenarios.
