- Requires work on the RFDS bulk update spreadsheet for filling required fields in different tabs like Individual and Final, which were mandatory requirements by the market.
Call Traffic Management
- Validate and execute scripts to be run in the Base Station Controller and make changes via GUI interfaces; monitor GPRS, call Traffic, and frequency associated with the TRX’s (BTS Hardware).
- Utilize the information provided by AT&T like FA Locations/RFDS ID/ Sites /ATOLL Name for Sites create and reassign it if required.
- Use ATOLL output to create the site, transmitter, and cell databases.
- Work on editing data in the RFDS bulk update sheet and master update sheet as per market requirements by entering the data manually.
- Work on CIQ creation and carrier add using customer inputs like RFDS, plumbing diagrams, and output from ATOLL.
- Work on post-processing tools like Actix to verify UMTS and LTE/5G log files for L3 event analysis (Call Drops, Call failures, and HO failures) and preparation of Walk test reports.
Implement TAC Changes on 4G LTE
- Migrating 4G LTE eNodeBs and CISCO SIAD from the source IP to the target IP addresses respectively, Implementing TAC changes on the 4G LTE eNodeBs, validating connectivity from Cisco SIAD towards eNodeB’s (4G)/NodeB (3G /UMTS) and MSN be performing the Ping Tests, Performing KPI (Key Performance Identifier) tests, QA (Quality Audit).
- Manage the operations of walk testing, which includes preliminary benchmark testing CW testing before using JDSU.
- Process and analyze UMTS and LTE coverage in and around the building, providing the benchmark test report.
- Provide coverage prediction plots for UMTS RSCP, EcNo plots, LTE RSRP, and RSRQ plots based on survey and benchmark reports using the iBwave design tool.
- Provide RF exposure plots and, based on the plots, provide any down tilts if needed in the neighboring Macro sites.
Perform Pre/Post Health Check of the Nodes
- Perform pre/post checks and health checks on the Nodes to determine the integrity of the network elements and address any issues that may have occurred before and/or after the provisioning process.
- Training of new Engineers in the Wireless Network Engineering Team.
- Work on Pre-Launch Activities, which include parameter Audit comparing snapshots and alarms to ensure optimum performance of the Metro cell.
- Monitor and report alarms to AT&T and MPC to resolve the Maintenance window if the site is set to Open Access.
- Check Missing neighbors in UMTS and adding them both ways in between Macro and Metro.
- Post Launch Activities include Daily monitoring of newly soft-launched venues for Voice and Data Accessibility, Retainability, and Hand over Mobility.
- Recommend changes to AT&T and, upon approval, implement them during the Maintenance window to improve the performance of Metrics to meet the target KPIs.
