On the other side, LTE-M and NB-IoT differ in terms of battery lifetime of connected devices, data throughput rate, roaming capabilities, device complexity, and coverage area and so on; on the other side which allows them to build various IoT enabled services that are examined in following sub-sections. Accordingly, Table 2 provides a brief information and useful comparison about both cellular LP-WAN technologies.

Table 2. General features of LTE-M and NB-IoT technologies
