Why do we need LPWAN networks? Such as the networks LTE M and NB-IOT. To support the continued growth and development of the Internet of Things. The mobile operators, together with the 3GPP standard, have standardized these new technologies in record time. LPWAN networks support low power consumption, more stable connections, higher building penetration, lower costs and optimal security.
LTE M and NB-IOT networks will play an important role in connecting the new generation of IoT devices, but in which countries are which LPWAN networks available? You can easily find this through the implementation overview on the GSMA website.
