responsible for below task : Installation & Commissioning: Setting up new cell sites. This includes installing radios, base band units, antennas, and running coaxial or fiber feeder cables. Testing & Validation: Using specialized equipment (like spectrum analyzers, cable analyzers, and signal generators) to measure signal strength, quality, and interference. Ensuring the newly installed site meets performance standards. Preventive & Corrective Maintenance: Performing routine checks on cell sites and responding to outages or alarms to restore service quickly. This can involve climbing towers or working on rooftop sites. Troubleshooting: Diagnosing issues reported by network monitoring systems or customers. This could be a hardware failure, a software bug, interference problems, or back haul (fiber/ microwave) connectivity issues. Optimization Support: Working with optimization engineers to improve network performance by adjusting antenna tilt, azimuth, power levels, or swapping hardware based on drive test data.Core Network Responsibilities: Equipment Installation & Maintenance: Installing and maintaining the physical hardware in a data center or central office (e.g., routers, switches, firewalls, and servers running network functions). Configuration & Integration: Loading software configurations, integrating new network nodes (like BSC , RNC and MME ...) into the existing network, and ensuring they communicate correctly. Troubleshooting: Using network management systems and command-line interfaces (CLI) to diagnose faults in the core network. This involves tracing user sessions, checking routing tables, and analyzing logs to pinpoint why a service (e.g., VoLTE calls, data sessions) is failing. Software Upgrades: Performing planned software upgrades and patches on core network elements with minimal service impact. Security: Implementing and maintaining basic security policies on network devices and ensuring compliance with security protocols.Common Cross-Domain Responsibilities: Collaboration: Working closely with other teams, including transmission (back haul), performance optimization, and customer care.
