What is the difference between LTE CAT 1 and CAT M1?

Cat M1, also known as LTE-M, low-cost machine-type communication (MTC) or LTE-enhanced MTC (eMTC) was developed by 3GPP as part of Release 13 of the LTE standard. Cat M1 aims to meet the needs of IoT devices based on the existing LTE carriers. eMTC supports peak data rates of 1Mbps for uplink and downlink. The speed and reliability of LTE Cat M are not as good as expected to cope with the IoT requirements of surveillance cameras and logistic tracking devices, leaving a technological emptiness in the field of middle-rate IoT connectivity.
