Cellular IoT

A low power LTE-M and NB-IoT solution for wide area network deployments

The LTE-M and NB-IoT standards are open standards created by 3GPP to allow wide deployment of IoT nodes while leveraging existing cellular infrastructure. The LTE protocols are designed for unparalleled scalability in number of nodes while maintaining good Quality of Service. Strong security is built in to the LTE link and industry standard security schemes are supported for end-to-end security. Both technologies will operate in licensed bands that are already being used for cellular communication. Leveraging existing infrastructure reduces the cost of ownership, and provides future-proof service.


Both technologies offer eDRX and PSM which are techniques for lowering the power consumption compared to traditional LTE. In eDRX, device and network agree exact times when the device will be ready to receive data. The radio link can be kept over the sleep period, so the connection will not have to be setup again when waking up. PSM allows the device to negotiate long inactive periods that are suitable for its use-case. After a period of inactivity, the higher level context setup procedure is lighter than normally, which saves on power consumption.
