NB-IoT: Low Data, low Frequency

If your battery-powered IoT devices operate for long periods without a power source or are used in hard-to-reach places like basements, NB-IoT is the ideal choice. While it supports only small data volumes, this cellular standard offers extremely long battery life, excellent building penetration, and cost-efficient connectivity.

LTE-M: Medium Data, low Frequency

The LTE-M standard provides sufficient bandwidth for medium data volumes, cost-effective hardware, and long battery life for deployments without a power supply. This makes it ideal for use cases such as e-health solutions that transmit vital signs to the cloud or cold chain monitoring in logistics.
