Huawei WLAN Products and Hardware
Domain 2 - Huawei WLAN Products and Hardware
This domain checks product positioning and hardware limits: which AirEngine AP fits an indoor high-density hall, which AC handles a branch, and how PoE and antennas affect deployment. Questions often test model selection and port/license constraints rather than configuration commands.
Core rules
- Huawei AirEngine APs are Wi-Fi 6/6E access points. Indoor models include ceiling and wall APs; outdoor models need weatherproofing and grounding. APs can be Fat (standalone) or Fit (managed by an AC), and many support cloud management.
- AC models scale by AP count and throughput. AC6005 is typically branch or small-campus; AC6605 and AC6805 serve larger campuses. Actual supported APs depend on model capacity and installed licenses.
- AP uplinks are usually GE or 10GE; PoE budget matters. 802.3af supplies about 15.4 W at the PSE, 802.3at about 30 W, and 802.3bt higher. An AP needing 802.3at may boot but disable radios on 802.3af.
- Antennas: built-in versus external, gain, and beamwidth. Higher gain is not always better in dense ceilings.
Worked example
A 60-AP dormitory needs an AC and PoE switches. You calculate 60 APs × 25 W = 1,500 W of PoE load, then check switch PoE budget and AC AP-license count. Choosing an AC with 64 AP capacity leaves little headroom; a model or license supporting more APs is safer. The reasoning is to size by simultaneous AP count and power, not by switch port count alone.
Traps
Do not confuse AC hardware capacity with the license you bought. Do not assume every GE port provides 802.3at. Outdoor APs still need surge protection and grounding. Fat APs do not need an AC but lose centralized roaming and management.
