NB-IoT can be deployed on both 2G (GSM) and 4G (LTE) networks, while LTE-M is solely for 4G. However, LTE-M is already compatible with the existing LTE network, while NB-IoT uses DSSS modulation, which requires specific hardware. Both are planned to be available on 5G.

What is NB-IoT?
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
What is LTE-M network?
LTE-M is a branch of LTE technology that was built for Machine-to-Machine communication. Using LTE-M, IoT devices can transmit and receive large amounts of data without draining the battery, as is the case with 2G, 3G and 4G networks.
What is difference between cat M1 and NB-IoT?
NB-IoT uses a narrower bandwidth (~200 kHz), compared to Cat-M1 which uses 1.4 MHz. As a result the maximum data rate for NB-IoT is around 250 kb per second. Compared to Cat-M1 - up to 1 Mbps.
What is LTE in IoT?
LTE stands for “Long-Term Evolution.” It's often conflated with 4G LTE, the fourth generation of global wireless communication and data transmission. LTE is one of the fastest-developing mobile technologies and connects one in four mobile users globally.
