Must Have Key skills:

Design and implement reliable wireless architectures using APOS (Access Point on Stick)
Configure VLAN tagging, trunking, and multi-SSID routing
Perform RCA for network outages and improve uptime
Monitor network via SNMP, syslog, dashboards (99.9% availability)
Conduct wireless site surveys (Ekahau/AirMagnet), RF analysis, and optimization
Ensure coverage planning, interference mitigation, and SLA validation
Implement redundancy & failover mechanisms (controller/AP, DHCP resilience)
Strong knowledge of 802.11 standards, WPA2/WPA3, 802.1X, Cisco/Aruba WLAN solution
Designed and implemented highly reliable wireless network architectures using APOS (Access Point on Stick) deployment models.
Configured VLAN tagging, trunking, and routing on access points to support multiSSID environments efficiently.
Performed root cause analysis (RCA) for network outages and implemented corrective actions to improve uptime.
Monitored network health using tools (SNMP, syslog, dashboards) to ensure 99.9% availability.
Optimized RF performance and channel utilization to reduce interference and improve reliability.
Implemented redundancy and failover mechanisms (controller/AP failover, DHCP resilience).

Wireless Survey & Optimization:

Conducted site surveys (predeployment & postdeployment) using tools like Ekahau / AirMagnet.
Performed RF coverage analysis, heatmaps creation, and capacity planning for enterprise environments.
Identified and mitigated RF interference, dead zones, and co-channel interference issues.
Recommended optimal AP placement, power levels, and channel assignments for maximum coverage and performance.
Executed wireless troubleshooting (latency, packet loss, roaming issues).
Validated network performance against SLA requirements and user density expectations.

Added Value Skills:

Expertise in 802.11 standards (a/b/g/n/ac/ax) and wireless security (WPA2/WPA3, 802.1X).
Experience with controller-based and cloud wireless solutions (Cisco, Aruba, etc.).
Strong understanding of QoS, roaming optimization, and load balancing in WLANs.
