Cat-M | Narrow Band (NB-IoT) Modules
Both NB-IoT and Cat M technologies have benefits to offer when it comes to low bandwidth IoT applications.
LTE-M is the best option for mission-critical applications, since it supports communication in real time. This includes voice, emergency data and precision tracking data. However, be aware that although LTE-M technology supports voice, it will be up to each network operator as to whether or not it gets implemented on their LTE-M network.
NB-IoT is ideal for smart city applications which send small amounts of data periodically, such as waste management, smart metering or street lighting.
