Cellular
LTE-M and NB-IoT
Low-power cellular for sensors and meters that send small amounts of data, designed for battery life measured in years.
What it is
LTE-M and NB-IoT are cut-down versions of 4G for low-data devices. LTE-M supports mobility and modest data rates; NB-IoT is optimised for very small messages from fixed devices deep inside buildings. Both use power-saving modes so devices sleep most of the time.
Where it fits
- Battery-powered sensors and trackers
- Smart meters and utility telemetry
- Devices deep indoors or underground
What to look for
- Network coverage for LTE-M or NB-IoT where the device will sit
- Data needs: these suit kilobytes, not video
- SIM plans built for very low data
For gateways and low-data SIMs, see our IoT gateways and SIM cards.
Part of our cellular hub. You will find the products we sell for this below, along with our explainers. If you are planning more than a handful of sites, talk to us before you buy: getting the router, antenna and SIM right first time saves site visits later.
Talk to an M2M and IoT connectivity specialist. Not sure which technology fits your project? Tell us what you need to connect and where, and our UK team will recommend the router, antenna and SIM, with pre-sales advice, after-sales technical support and a range of configuration options.
Questions
Can a router use NB-IoT?
Routers are usually 4G or 5G. LTE-M and NB-IoT are mostly built into sensors and modules rather than routers.
