LTE Cell Planning and Optimization

Digital transmitters send signals from radio tower

This course introduces participants to the Long Term Evolution (LTE) or 4G cellular network. The radio channel conditions, RF propagation and frequency planning will be presented at the start of the course. Subsequently, participants will be introduced to the practical issues of air interface that can be resolved by OFDM / MIMO.

Link budgets, cell edge and capacity coverage principles will also be explained and described in detail. Attention will be given to post processing techniques like KPI analysis and troubleshooting.

These various techniques covered in this class will equip participants with the necessary knowledge in handling post processing tools and developing ideas which are useful to optimising radio access network with real network traffic.

  • Mobile Networks Engineer who wish to learn about LTE planning and optimizing principles
  • Radio network planners who wish to learn more about the e-UTRAN
  • Multimedia Engineer who wish to learn the concepts and theory of LTE-SAE that transports your services to the users
Instructor-Led Training
[Classroom: 5 days / LIVE Virtual*: 35 hours]
 
*Note:
 
  • A minimum of 5 or more participants are required for a company-based LIVE Virtual course to commence
  • LIVE Virtual courses can be conducted for 5 hours or 7 hours daily. Please note that the number of training days will be extended if you opt for 5 hours daily.

This course is designed to accommodate the earlier versions of mobile access technologies such as UMTS and GPRS. It will also prepare course participants for LTE and VoLTE implementation. Cell dimensioning in an LTE network is critical due to the different types of services that can be offered by LTE.

By attending this course, participants will learn how to calculate link budgets and undertake cell planning for
users in the cell edge (under worst case scenario). Network interference is a critical factor to be considered and therefore needs to be account for in the throughput calculation and frequency planning with the scheduler.

Through mastering such techniques, participants will learn how to improve throughput optimization and end-user experience.
