Insights from The Largest NB-IoT Indoor Measurement Campaign So Far

Deutsche Telekom’s NarrowBand IoT (NB-IoT) network has proven its capabilities in the largest known NB-IoT indoor measurement campaign conducted so far, achieving a 100% attach rate above ground and a 95% attach rate in basements. This meets and even exceeds the expectations for NB-IoT to perform better than existing cellular technologies such as 2G/3G/4G. Once attached to the network, data transmission for each measurement cycle was possible in practically all cases (99.75%).

The measurement campaign was initiated by Deutsche Telekom and independently performed by P3 Communications GmbH in co-operation with ista International GmbH, which provided access to the measurement locations. Measurements were done for about 500 position pairs in and around 60 apartments. One position pair is defined as one outdoor position and one corresponding indoor position. The measurement results prove the capability of NB-IoT in a typical real-world usage scenario in Deutsche Telekom’s live network.
