Corrective Maintenance (CM)

Corrective Maintenance involves prompt identification, troubleshooting, and resolution of faults or failures within network infrastructure to restore normal operation as quickly as possible. ERA GROUP’s CM approach includes:

• Rapid Fault Diagnosis: Utilizing advanced diagnostic tools and remote monitoring systems to detect and accurately pinpoint issues in hardware, software, or connectivity.

• On-Site Repair & Replacement: Deploying skilled field technicians equipped to replace faulty units, circuit boards, antennas, transceivers, power modules, or other critical components.

• Emergency Response: Offering 24/7 availability to respond swiftly to outages or degraded performance, minimizing downtime and service disruption.

• Root Cause Analysis: Conducting thorough investigations post-repair to identify underlying issues and prevent recurrence, contributing to long-term network stability.

• Comprehensive Reporting: Documenting maintenance activities, parts used, and timelines to maintain transparency and facilitate performance tracking.

Preventive Maintenance (PM)

Preventive Maintenance is a proactive strategy designed to avoid equipment failures before they occur, thereby maximizing uptime and extending asset lifespan. ERA GROUP’s PM services include:

Scheduled Inspections

Routine visual and technical checks on all network components, including active equipment, power systems, and site infrastructure.

Routine Servicing

Cleaning, lubrication, firmware updates, and calibration of devices to maintain optimal operating conditions.

Consumables Replacement

Timely swapping of batteries, filters, seals, connectors, and other wear-prone parts to prevent unexpected failures.

Performance Testing

Conducting diagnostic tests such as signal strength measurement, load testing, and environmental condition monitoring.

Predictive Analytics

Leveraging monitoring data to anticipate potential faults and schedule maintenance interventions accordingly.

Maintenance Planning

Developing and executing tailored maintenance schedules aligned with manufacturer recommendations and operational priorities.

Active & Passive Maintenance

Active Maintenance

involves hands-on servicing and repair of electronic and radio equipment such as BTS/Node B, RRUs, antennas, transceivers, routers, switches, feeders, and fiber jumpers. This includes troubleshooting faults, replacing defective components, and optimizing RF performance to ensure consistent network availability.

Passive Maintenance

focuses on the upkeep of supporting infrastructure without direct interference with live network signals. It covers tower inspections, shelter integrity, cooling systems, power cabinets, batteries, generators, solar panels, fencing, grounding systems, and air-conditioning units — all essential for protecting active equipment and ensuring site stability.

Spare Parts Management

Effective spare parts management is crucial for reducing network downtime and accelerating repairs. ERA GROUP maintains an organized inventory of critical components—including antennas, RRUs, routers, switches, power supplies, and consumables—ensuring rapid availability when replacements are needed. Our system tracks stock levels, predicts demand based on usage trends, and facilitates timely procurement to support ongoing maintenance and emergency interventions.

NOC (Network Operations Center) Services

24/7 monitoring and control of telecom, fiber, and data center infrastructure. Functions include:

• Alarm surveillance and real-time fault detection.
• Incident resolution within SLA targets.
• Performance monitoring, capacity planning, and network optimization.
• Technical helpdesk support and escalation management.

Site Security

Protecting telecom sites from theft, vandalism, and unauthorized access is essential for uninterrupted operations. ERA GROUP provides dedicated on-site security personnel trained to safeguard assets and personnel. Our security services include controlled access, perimeter monitoring, CCTV surveillance, and rapid response to incidents, ensuring the physical safety and operational integrity of mobile network infrastructure.
