Understanding LTE Cat M1 (eMTC)

Summary

eMTC may be an easier way to cater to IoT devices by having Small cells (Femto) with eMTC functionality. The article has provided sufficient information for LTE RAN/UE developers to get core understanding of eMTC. Please go through documents mentioned in References below for more information and details.

You may also refer FAPI document [12] (Rel 13/eMTC specific portions) to get insight into implementation of these enhancements from PHY point of view.
