 Physical Parameters Verification of new sites and Swap as per the planning data.
 Responsible for KPI TEST scenarios for the performance management of LTE integrated
sites. (Test consisted of points such as Data Uplink & Downlink, Ping Test, handovers
checking, circuit-switched fallback and carrier aggregation)
 Monitoring & Ensure consistent RSRP, RSRQ and SINR parameters performance for better
coverage of the site.
 Modifying the threshold And Cell parameter for better cell-reselection 3G to 4G.
 Co-ordinate with DT team members for supporting them to overcome any issues arising
on the field.
 Investigating the new/swap sites in the network after the integration/swap and scheduling
drive test for network services.
 Responsible for checking the radio performance for the newly integrated LTE sites.
 Statistical analysis for Quality Improvement by regular KPI checks (Accessibility,
Retainability, Mobility, Availability and Integrity) and specific counters checks for
troubleshooting like the RRC drop reasons, RRC connection fails and HO prep fails.
 Daily worst performing cell check based on KPI criteria and optimize them by the
recommendations.
