Arabia 4G/5G, Major Duties: Expertise in performing drive Test using PROBE/TEMS Investigation for 2G and 3Gcell sites
Working on MAPINFO tool for Drive test route planning, data analysis, Neighbors listsdefining
RF Coverage optimization using antenna tilt and azimuth fine tuningfor optimal coverage overlap and reduction of pilot pollution by
ECNO and RSCP improvements
Troubleshooting and Parameter Optimization for variousproblems like poor Coverage, HO Failure and Traffic Channel
Problem
Troubleshooting problems like missing neighbors, coverage holes,pilot pollution areas, areas of no dominance, code plan problems,overshooting sites, parameter inconsistency etc
Through drive loganalysis
To verify 2G to 3G & 3G to 2G cell reselection and Handovers
Responsible for performing Pre-drive test and post-drive test for newsite, BSC migration Drive Test
TRX performance test, with MOC & MTC and Handovers Inter & Intra
Ping test for 3g sites and Drive Test for New on air 2G sites to diagnosing Radioparameters
Expertise drive in Site Integration, Coverage, PS test, Benchmarking,
Monthly Cluster drives, RNC and BSC re-homing handover drives etc
Analysis of RF interference, Call drops, Handover failures and TCH assignmentsuccess rate etc
Network improvement by fixing Call Drop, Rx Quality, SQI etc
And Network performance analysis
Site Auditing for existing sites to verify site database and cell designcriteria's (checking Azimuths, Mechanical tilts, Electrical tilts, andpanoramic views etc.)
2G Frequency Scanning in idle mode for interfering frequencies insector to sector or in serving cell to neighboring cell by using TEMS
Identification of faults and issues during the drive test e.g
Sectorswaps (complete & partial), BCCH clashes (adjacent and co-channelinterference), Handover failures, Call drops, bad Quality and Rx levelpatches, Missing neighbors Over shoot etc
Verification of cell design and Antenna Parameters
Identification of low power and faulty TRXs and doing the time slot verification
Checking for Inter-site & Intra-cell handovers and perform neighborverification.
