The LTE system supports broadband wireless access in a mobile cellular environment, and is considered the next generation (beyond 3G) wireless system, offering data rates in the range of 100 Mbps. The LTE system is based on the OFDM-based radio air interface. The LTE system also deploys advanced antenna techniques to increase the throughput, coverage and capacity of the network. Thus, deploying the LTE system is going to provide a unique and challenging opportunity. This workshop covers the radio network planning and design aspects of an LTE network and describes the process of mapping the service and market requirements to RF system parameters. This certification workshop utilizes several hands-on exercises and a coverage prediction tool for RF design project and concludes with a certification assessment. Required Equipment: PC laptop with administrator priviledges
Learning Objectives
After completing this course, the student will be able to: • Explain the process of radio network planning and design • Describe the frame structure, DL&UL channels and key measurements like RSRP and RSRQ of the LTE air interface • Map the network requirements to corresponding system parameters • Explain multiple antenna techniques in LTE and selection considerations • Step through the UL and DL link budget for the LTE system • Design the radio network based on coverage and capacity requirements • Step through the coverage prediction and site selection process • List and describe key configuration and operational parameters • Identify the key performance indicators of LTE radio network • List and describe the key parameters related to Inter-RAT operation
