Wi‑Fi interoperability is often requested for customs, platforms, and factory audits. This is the 2026 practical guide.

I. Core Standards

Based on Wi‑Fi Alliance official specifications and:

·IEEE 802.11b/g/n/ac/ax

·WPA3 security (mandatory in 2026)

·20MHz narrowband for IoT

·EasyMesh for Mesh products

II. Actual Test Items

·Connection with major router brands

·Band switching and roaming

·Multi‑device stability

·Sleep/wake reconnection

·Throughput and long‑term performance

·WPA3 and management frame protection

·Low power and weak‑signal performance (IoT)

III. Applicable Products

All Wi‑Fi consumer devices:

·Smart home: plugs, switches, lights, thermostats, locks

·Audio: speakers, projectors, set‑top boxes

·Security: cameras, doorbells

·Networking: routers, repeaters, gateways

·Tablets, VR, Wi‑Fi appliances

IV. Important Notes

·Tests must be done in Wi‑Fi authorized labs.

·WPA3 is mandatory.

·Must cover multiple router brands.

·Hardware/firmware changes require retesting.

·Maintain valid Alliance membership.

·Optimize firmware early to avoid delays.
