LTE optimization training course description

This course gives delegates an understanding of the Key Performance Indicators used within the 3G LTE (4G) network environment. We investigate the 3GPP standards for KPIs (including TR 32.814, TS 32.410 & TS 32.455) these cover GERAN, UMTS & LTE environments. The course details the optimisation procedures and the use of Self optimisation, Selforganising & Self-healing equipment now being deployed across all releases of mobile networks.

What will you learn

• Explain the RF optimisation flowchart.
• Describe the importance of Reference Signal Received Power (RSRP).
• List many of the 3GPP recommended KPIs.
• Describe the concept of APN AMBR and UE AMBR within LTE.
• Describe the use of planning and optimisation computer tools.
