HCIP-WLAN study guide
HCIP-WLAN · Work through your exam, one topic at a time.
HCIP-WLAN is Huawei's professional-level certification for wireless LAN engineers, aimed at people who already know basic 802.11 concepts and now design, deploy, secure, and troubleshoot enterprise WLANs built on Huawei access controllers and access points. Typical candidates are network engineers, deployment and field engineers, and pre-sales or support staff moving from general routing and switching into wireless specialization. The HCIP-WLAN study guide has 8 sections and about 2,325 words.
01WLAN Fundamentals and Standards
Domain 1 tests how 802.11 PHY and MAC choices shape real WLAN behavior, plus the RF arithmetic behind coverage and channel reuse. 802.11a uses 5 GHz OFDM; 802.11b/g use 2.4 GHz; 802.11n adds MIMO on both bands; 802.11ac is 5 GHz only; 802.11ax (Wi-Fi 6) adds OFDMA, MU-MIMO and BSS coloring on 2.4/5/6 GHz.
331 words, about 2 min02WLAN Networking and CAPWAP Principles
Domain 2 covers fit AP-AC architecture, CAPWAP tunnel setup and the onboarding steps that turn a powered AP into a managed radio. Fit APs hold little configuration; the AC supplies service and radio settings.
298 words, about 1 min03WLAN Air Interface and Roaming
Domain 3 examines 802.11 frame handling, client roaming and band steering: how a client moves from one AP to another without dropping a voice or video session. Management frames build and maintain the link: beacon, probe, authentication and association.
298 words, about 1 min04WLAN Security
Domain 4 tests the security chain from the wireless cipher to authentication, authorization and accounting, including certificates and guest access. WEP uses RC4 with weak IVs and is deprecated.
276 words, about 1 min05WLAN QoS and WLAN Optimization
Domain 5 covers WMM quality of service, air-interface control and the planning choices that determine capacity rather than just coverage. WMM is the Wi-Fi Alliance profile of 802.11e EDCA.
281 words, about 1 min06WLAN High Availability and WLAN AC Deployment
Domain 6 covers AC high availability: how to keep APs and clients served when an AC or link fails, and how VRRP, dual-link backup and AC virtualization differ. Two ACs share a VRRP virtual IP.
274 words, about 1 min07WLAN O&M and Troubleshooting
Domain 7 is operational: planning, monitoring, upgrading and diagnosing WLAN faults in a repeatable order. WLAN Planner supports site survey, AP placement, channel/power planning and heat maps.
265 words, about 1 min08WLAN Interworking and Application Scenarios
Domain 8 connects the WLAN to the wired network and to cloud, IoT and location services. The exam tests whether you can place VLANs, gateways and tunnels correctly and recognize cloud dependencies.
