As a typical example of wide area networks, the LTE-Advanced cellular network is a 4G cellular network standardized by 3GPP. LTE-M and NB-IoT are the 3GPP's latest standardization work for low-power machine-type communications. LTE-M and NB-IoT provides a cellular IoT solution on top of the existing cellular networks. They can provide flexible coverage for various IoT use cases. Learn the cellular IoT basics and the typical use cases for IoT applications.
