LTE-M is a cellular standard for IoT devices that need to move. A parcel tracker inside a courier bag passes through multiple cell towers during a delivery. LTE-M handles the handover between towers automatically – the connection stays alive as the asset moves. NB-IoT cannot do this.
LTE-M provides download speeds up to 1 Mbps and supports voice over LTE. It consumes more power than NB-IoT but less than standard 4G LTE. Use LTE-M for moving assets; use NB-IoT for stationary sensors in hard-to-reach locations.
- Cell handover – maintains connection as the device moves between cell towers
- Data rate – up to 1 Mbps down / 1 Mbps up; enough for regular position reports and FOTA updates
- Power modes – PSM and eDRX allow deep sleep between reports for battery efficiency
- Voice support – relevant for some personal safety and worker tracking applications
- Frequency – runs inside existing LTE bands, available on most EU operator networks
