TSEL LTE Handover Failure 11Dec2014_V1.pptxLTE CLUSTER Handover Failure due to overshoot from interference site DURIMAS Report

10 December 2014 Huawei Confidential www.huawei.com

Analysis:HO Fail due to coverage from overshooting signal from site DURIMASMT, to JELAMBARSLTN, need to AUDIT nearest site TJGDUREN and FARIACARGOMT due to not served spot area.

Action:Troubleshoot interference problem on JELAMBARSLTNMT and Down tilt DURIMASMT from M-Tilt 2/2/2 to 6/6/6After Audit FARIACARGO, from Panoramic 200degree poor coverage due to signal blocking by dense high building at surrounding area

Solution:For 1,2&3, propose down tilt site DURIMASMT to avoid overshooting from this siteFor 4, need to Re-DT for LATUMENTENMT area.

Analysis:Drop service due to poor coverage from overshooting signal from site DURIMASMT, to JELAMBARSLTN, nearest site TLKMSLIPIMT and FARIACARGO can cover bad spot area due to blocking signal by high building surrounding area.

Action:Troubleshoot interference problem on JELAMBARSLTNMT and DURIMASMT, propose site audit. Audit FARIACARGOMT and TLKMSLIPIMT.Site audit FARIACARGO, blocking by Trisakti University building
