  • Provide mounting standards, labeling scheme, and patching guidelines.
  • Review and finalize bill of materials (APs, controllers, licenses, accessories).

2. Deployment & Configuration

  • Supervise contractor's AP mounting and cabling; perform spot-checks for compliance.
  • Configure controllers (Aruba CoP/Central, Cisco WLC, Ruckus SZ).
  • Apply SSID, VLAN, authentication/security policies, and RF optimization features.
  • Integrate with LAN/WAN, DHCP/DNS, NAC (ClearPass/ISE), and firewall rules.

3. Testing & Validation

  • Conduct post-installation validation survey (coverage, SNR, utilization).
  • Perform functional and performance testing (SSID broadcast, roaming, throughput, latency).
  • Validate security and guest access workflows.
  • Support customer UAT and track punch-list items for contractor fixes.

5. Go-Live & Hypercare

  • Monitor Wi-Fi during go-live stabilization (1–2 weeks).
  • Troubleshoot and fine-tune RF or policy issues.
  • Escalate and close contractor defects (e.g., misaligned APs, cabling faults).
  • Ensure monitoring and auto-ticketing are operational in NetGain + ServiceNow.

6. Deployment Efficiency & Continuous Improvement

  • Develop reusable configuration templates and automation scripts (APIs, Ansible, REST).
  • Standardize naming conventions, VLAN mappings, and deployment playbooks.
  • Capture lessons learned after each project to improve rollout speed and quality.
  • Maintain a deployment "best practices" library for engineers and contractors.

7. AIOps & NetGain Integration

  • Ensure Wi-Fi controllers stream telemetry (SNMP, Syslog, APIs) into NetGain.
  • Define and monitor key KPIs (onboarding success, AP utilization, roaming, SLA thresholds).
  • Enable anomaly detection and predictive alerts via NetGain AIOps.
  • Integrate auto-ticketing with ServiceNow enriched with root-cause context.
  • Pilot and adopt self-healing scripts (e.g., auto-adjust radio power, restart failing AP radios).
  • Track vendor AIOps capabilities (Aruba, Cisco, Ruckus) and align them with NetGain strategy.
