NB-IoT has a wide range of performance advantages when deployed for IoT applications that have low data rates, long battery lives and that operate unattended for long periods of time. NB-IoT allows for network deployment with only 200 KHz spectrum and a 20dB coverage gain compared to existing cellular-based solutions.
In the field trial which took place on its local network in Bonn, Deutsche Telekom and Huawei were able to evaluate the capabilities of NB-IoT under real commercial conditions and test the usability of NB-IoT for a first application to provide a smart parking to selected users. The field trial focused on verifying the performance of the technology in a variety of challenging, actual deployment scenarios.
