Overview

What the RCWE certifies.

The RKR Certified Wireless Expert (RCWE) is the terminal credential of RKR's wireless stream — an expert-tier program built for engineers who already run production WLANs and now need to own the problems nobody else can solve. Where RCWP taught you to design and secure enterprise Wi-Fi, RCWE trains you to perform packet- and RF-level forensics on 802.11ax/be networks, architect multi-controller estates spanning tens of thousands of clients, engineer very-high-density venues like stadiums and convention centres, and converge Wi-Fi with private 5G/CBRS and centimetre-grade location services. Every module is anchored to real platforms — Aruba Mobility Conductor and AOS 10 gateway clusters, ClearPass, Ekahau AI Pro and Sidekick 2, Wireshark/802.11 protocol analysis, Celona/Athonet private-cellular cores — and every claim of competence is demonstrated on hardware, not on slides.

RCWE exists because India's AI-infrastructure build-out is colliding with a wireless talent cliff. GigaWatt-scale datacenter campuses, smart factories, and Industry 4.0 sites all need deterministic wireless — Wi-Fi 7 with MLO, CBRS-band private 5G, RTLS for robotics and asset flows — and the engineers who can design, troubleshoot, and defend those systems are among the scarcest and best-paid in the market. The program is deliberately comparable in rigor to Aruba ACMX and CWNP CWNE: it culminates in a proctored, rubric-graded eight-hour practical lab exam plus a design-defense viva, so an RCWE holder walks into an interview with verifiable, demonstrable expert competence — the RKR standard of "networks first, networks last."

The syllabus

9 modules. 21 graded labs. No filler.

Every module terminates in a graded lab — theory is never left unproven. This is the full RCWE module sequence, exactly as delivered.

RCWE-M01

Covers Wireshark/Omnipeek dissection of 802.11ax and 802.11be frames — OFDMA trigger frames, BSS Coloring, MLO link setup, Target Wake Time — plus AOS 10 debug tooling (show ap debug, client-match telemetry, ucc datapath statistics) and roaming forensics for 802.11r/k/v and OKC failures.

You will be able to
  • Learner can capture and merge multi-channel 802.11 traces (monitor-mode adapters + AP-based capture) and reconstruct a client's full connection timeline
  • Learner can root-cause roaming failures by decoding FT-over-Air/FT-over-DS exchanges, PMKID caching, and 802.11v BTM transaction outcomes in a PCAP
  • Learner can diagnose EAPOL 4-way-handshake and EAP-TLS failures to a specific certificate, timer, or RADIUS attribute defect
  • Learner can interpret 802.11ax/be-specific behaviors — trigger-frame scheduling, BSS Color collisions, MLO link preferences — and separate protocol defects from RF defects
  • Learner can drive AOS 10 and Aruba Central debug workflows (client trail, AI Insights, datapath session dumps) to close a fault with documented evidence

Mock Lab Exam II + Design Viva

Second timed run with a fresh fault set plus the VHD implementation brief, followed by a live 30-minute design defense before two RKR principal engineers with written scoring feedback.

How you’re examined

The RCWE exam format.

Two-stage, both proctored at RKR's Bengaluru lab or via monitored remote rack access. Stage 1 — Theory (120 min, 70 scenario items): PCAP excerpts, spectrum captures, Ekahau heatmaps, and AOS 10 CLI output that the candidate must interpret; pass mark 75%. Stage 2 — Practical Lab Exam (8 hours, rubric-graded): a live rack with Mobility Conductor + two Mobility Controllers, an AOS 10 gateway cluster under Aruba Central, Wi-Fi 6E/7 APs (630/650/730 series), ClearPass, a Celona-class CBRS small cell with SAS sandbox, and a BLE/RTLS testbed. Candidates must (a) restore a deliberately broken multi-controller estate from 12 seeded faults spanning roaming, RF, AAA, and clustering, (b) implement a VHD design brief to stated airtime and SLA targets, and (c) defend their design decisions in a 30-minute viva with RKR principal engineers. Grading is against a published 100-point rubric; 80+ passes. One free lab retake within 12 months.
