RKR Certified Wireless Expert
Expert-tier wireless: forensics, venue-scale design, private 5G — proven on the bench, defended in the viva
The blueprint
A 20-week, 21-lab expert program that builds the complete last-line wireless engineer: packet- and spectrum-level forensics on 802.11ax/be, stadium-grade very-high-density design, 25,000-client multi-controller architecture, CBRS private 5G convergence, sub-metre RTLS, and AIOps-driven assurance — culminating in an 8-hour practical lab exam and a live design defense comparable in rigor to Aruba ACMX and CWNP CWNE.
Skill domains
6 assessed domainsProtocol & Spectrum Forensics
- Multi-channel 802.11ax/be capture analysis: roaming (11r/k/v), OFDMA, MLO, EAPOL failures
- FFT/duty-cycle interferer identification, DFS event forensics, physical source localization
Very-High-Density & Venue Design
- Per-seat airtime and throughput budgeting for 40,000-seat venues
- Sectorized directional-antenna engineering, under-seat mounting, event-day validation
- Wi-Fi 6E/7 in VHD: where 320 MHz, MLO and MRU help — and where they hurt
Multi-Controller & Cloud Architecture
- Mobility Conductor hierarchies, AOS 8 hitless clustering, AOS 10 gateway clusters
- L3 roaming, multizone tenancy, zero-downtime AOS 8→10 migration
Private 5G / CBRS Convergence
- SAS grant workflow, CBSD registration, India CNPN spectrum routes
- Compact 5G core (AMF/SMF/UPF), SIM provisioning, 5QI QoS, Wi-Fi/5G steering
Location Services & RTLS
- BLE 5.1 AoA sub-metre positioning and 802.11az/FTM ranging
- Ground-truth accuracy validation, MQTT/REST pipelines, geofenced workflows
Security & AIOps at Expert Scale
- WPA3-Enterprise 192-bit (CNSA), 20k-endpoint EAP-TLS, WIPS attack forensics
- Central API automation, streaming telemetry, synthetic assurance, closed-loop remediation
Signature labs
Rack time, not watch timeBreak/Fix Gauntlet — clear 12 seeded compound faults across a live multi-controller estate in 8 hours
Stadium Bowl Design — 40,000 seats modeled, budgeted and defended in Ekahau AI Pro
Private 5G Greenfield — SAS grant to attached industrial UEs with measured URLLC latency
Interferer Signature Hunt — five hidden RF sources identified and localized to 3 metres from spectrum alone
Hitless Failover Under Fire — sub-second controller failover proven by packet capture under live voice load
Attack Reconstruction — three over-the-air attacks timelined from 2 GB of defensive captures and briefed to a mock CISO
How you are examined
Stage 1: 120-min proctored scenario theory (PCAPs, spectrum plots, CLI output) — pass 75%. Stage 2: 8-hour rubric-graded practical on a live rack (Conductor + MC clusters, AOS 10 gateways, ClearPass, CBRS small cell, RTLS testbed) plus a 30-minute design-defense viva — pass 80/100. One free lab retake within 12 months.
