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.
