What is LTE-M?

LTE-M is a licensed LPWA network that is a 3GPP standards-based technology evolution of LTE specifically built for IoT devices.

LTE-M offers greater indoor penetration, subterranean coverage and extended device battery life at lower costs while leveraging the existing AT&T LTE RAN infrastructure and existing licensed spectrum. LTE-M is also known as LTE CAT-M, CAT-M, or CAT-M1.
