LTE optimisation and capability

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.
