Current Job Description:

Presently Works for Pacific IT Consulting Pvt. Ltd. As Senior LTE RF Optimization Engineer From 02nd January 2018 to till date in Chennai.

Current Project- Sprint Mobile FSM4 BBU SWAP USA

Project Description: Replacing Former ALU BBU with Nokia FSM4 BBU For Sprint Mobile Both FDD & TDD Band. After site migrated to Air-scale Nokia FSM4 we are responsible for Hourly Monitoring for 48 Hour and Daily Monitoring up to 10 days from migration date, also we are monitoring existent CDMA & EVDO network KPI’s after migration for checking any impact on KPI Stats. Once site is migrated and assigned to us we are responsible for end to end delivery of site.

Any degradation in KPI’s we are doing analysis and finding root cause for degradation in KPI’s. Also, we are doing Parameter and power Audit with the Help of Mapping rule and finding discrepancy in parameter and reference signal power for site which was migrated & impacted with KPI’s. implemented same in Maintenance window (MW) and Post KPI’s checking.

Apart From this we are taking follow-up with FM & AM Team for clearing Alarm on Site, Parameter, Power Changes,

ANR Reset & Site Reset.
