LTE-M and NB-IoT in the Low Power Wide Area (LPWA) cellular deployment have requirements such as low cost, enhanced coverage, high capacity, and long battery life. This course describes network architecture enhancements in LTE networks for IoT such as NIDD and SCEF. The fundamental operations such as network acquisition, random access, RRC connection setup, data transfer, and mobility are covered. This course requires message traces provided by the customer to step through various scenarios and exercises.

Technical personnel working for wireless operators, equipment and device manufacturers, who need a detailed look at LTE-M/eMTC and NB-IoT.

After completing this course, the student will be able to:
■ Describe key features of LTE-M and NB-IoT
■ Illustrate the network architecture with LPWA enhancements
■ Explain how of PSM and eDRX help increase UE battery life
■ Describe how EAB and optimized TAU reduce the signaling load
■ Summarize key parameters of System Information messages for LTE-M and NB-IoT
■ Discuss Attach enhancements for LTE-M and NB-IoT
■ Describe key operational configurations of LTE-M and NB-IoT physical channels
■ List main KPIs for LTE-M and NB-IoT
