In measuring the performance of 4G LTE network, drive test and post processing helps to gather real time statistics from the network and process them to get various insights about the network. These statistics are related to coverage, quality, capacity and derives the experience perceived by the customer. Live simulations of Layer 3 messages through drive tests are also captured. This course includes -

• Network Optimization Flowchart
• Performance Indicators from Drive Test such as Coverage (RSRP), Quality (RSRQ/SINR), DL Throughput, Mobility, Walk Test, 4G Data testing
• 4G (LTE) Drive test Live – JDSU Tool
• 4G (LTE) Post Processing – Gladiator Tool

Once performance of 4G LTE network is measured through OSS, drive test and post processing, the next step is to identify the issues observed in the network, be it related to coverage, quality, integrity etc. and then take actions to resolve them. Hard and Soft optimization along with new feature implementation can be done and are explained in this section.

• Coverage planning – Link Budget and Coverage Prediction
• Coverage Optimization for Weak Coverage, Overlapping – Pilot Pollution, Overshooting
• Soft Parameters Optimization
• Resource allocation – Downlink & Uplink, PDCCH calculation
• Spectral efficiency, Capacity and Throughput Optimization
• Analyze the reasons of Low Throughput
