ABOUT THE COURSE
Advanced/Expert Level-III course, possess medium though advanced concepts of 4G LTE & LTE-A RF Planning & Optimization and Network Troubleshooting. The course is categorized into 10 parts, i.e.
█ 4G RF Design █ Adv. MIMO Antennas █ KPIs █ 4G Planning
█ Drive Testing █ Log file Analysis █ SSV Design █ Optimization
█ Troubleshooting █ Case Studies
The course discusses real-world RF Planning concepts regarding practically implemented 4G Networks, i.e. Initiating from Sites Planning, Spectrum allocation, Physical, Logical & Transport Channels, Call and SMS handling, Advanced MIMO Antennas and Network Planning.
RF KPIs will be evaluated during Drive Test activities, RAN tuning of Coverage, Quality, Interference, Neighboring parameters, Testing of 4G Network Throughput and Troubleshooting RF related problems would be covered in great detail. The participants will learn how to improve network parameters, along with Analysis, Reporting and suggesting Recommendations regarding network enhancements.
