NB-IoT & LTE-M are the technologies the GSMA has recommended as the ‘massive’ component of the official 5G standard. They build on the success of the established LTE standard and inherit its strong security features. This includes one-SIM authentication to mutually authenticate both network and device generated session keys for encrypting traffic between device and network. You could say it’s an evolution of an evolution.
Mobile operators around the world have chosen NB-IoT and LTE-M as the standards for LPWA. This gives you the confidence of knowing you are investing in a technology with a future.
For applications that don’t require a lot of data, why pay for it? NB-IoT it sends small amounts of data at set time intervals. And both LTE-M and NB-IoT can sleep for extended periods of time. And due to mass adoption, module costs are in freefall too.
NB-IoT and LTE-M can go places other technologies can’t. They penetrate deep inside buildings and under the ground. Both support enhanced signal coverage. And because they connects sensors directly to the mobile network, and you don’t need additional gateways.
Batteries may be cheap, but replacing them isn’t. NB-IoT & LTE-M are optimised for low power usage, which means 10 year battery life is now a reality. It all depends how you want to use it.
NB-IoT & LTE-M have a clear advantage over proprietary technologies that rely on shared spectrum. As the number of connected things increases, so will interference. In shared spectrum, this will increasingly require data to be re-sent – which will not just affect performance, it will also deplete batteries a lot faster than some of the promises flying around. With dedicated spectrum, you’re in the clear.
