backtotop.gifTraining Course Description

  • This course addresses the needs of technical engineering staff who require a thorough understanding of of Cat-M / LTE-M.
  • Cat-M is considered as a minor upgrade of existing LTE-A network and UE software but the understanding of the details and the operation of LTE-M is very complicated.
  • This course has been designed to meet the requirements of both: engineering experts to design and test Cat-M related equipment, in particular on the UE-side and operations staff who require detailed knowledge about Cat-M network configuration.
  • The course starts out with a short overview of long range IoT-technologies like NB-IoT and compares them with each other.
  • This chapter ends with a detailed description of the various 3GPP-endorsed UE-categories for machine type communication.
  • The whole next chapter is dedicated to a bit level elaboration of Cat-M operation.
  • Starting with a thorough description of the details and meaning of CE-levels and CE-modes, the course continues with a detailed description as to how a BL-UE finds and reads the Cat-M related system information, namely but not limited to SIB1-BR.
  • This chapter leaves no questions unanswered w.r.t. random access in Cat-M, resource allocation through MPDCCH and HARQ-operation.
  • We also dedicated quite some focus on MCL-calculation for different channels under different circumstances to enable operators to come up with suitable repetition numbers.
  • This chapter terminates with the calculation of achievable throughput rates in Cat-M, both uplink and downlink, to allow you benchmarking your own results from the field or from the lab.
  • Focus of the next chapter is higher layer operation and starts out with the description of DRX-operation for Cat-M, distinguishing I-DRX and C-DRX. This part is a nice introduction for the following part: the detailed description of eDRX and its use in Cat-M.
  • We will continue with a description of the specifics of the attach procedures for Cat-M, including an analysis of power saving modem its comparison with eDRX.
  • The course ends with a description of control plane and user CioT-optimizations, their use cases and specifics.

Some of your questions that will be answered

  • What are the differences between CE-level and CE-mode?
  • How can blind retransmissions improve the overall system performance?
  • How does the Cat-M UE find and read the BL-specific system information?
  • How does the random access procedure work in LTE-M?
  • How does a cell allocate resources in Cat-M? How does the MPDCCH operate?
  • How does HARQ operate in LTE-M?
  • What are achievable throughput rates in Cat-M in both directions?
  • How does DRX operate for LTE-M?
  • Which impact on DRX does eDRX have w.r.t. LTE-M?
  • How do attachment and bearer setup work for LTE-M?
  • How does PSM operate and how does it correlate with eDRX?
  • How do CIoT-optimizations operate?


  • This is a bit-level course: The students should have detailed knowledge of LTE and LTE-Advanced prior to visiting this course.
