Wi-Fi 6 (802.11ax) Modules from China
1 resources tagged with "802 11ax"
802.11ax is Wi-Fi 6 (and 6E with the 6 GHz band), and Chinese module vendors build around silicon like Qualcomm QCN9074, MediaTek MT7921, or Espressif's ESP32-C5 for low-power IoT. The features worth paying for are OFDMA and Target Wake Time (TWT), which cuts radio-on time and meaningfully extends battery life on sensor nodes. The sourcing catch is the 6 GHz band: 6E operation needs separate FCC and CE authorization, and a module's 6 GHz support is only usable where it's certified.
When you source 802.11ax modules, the pitfall is assuming 6E/6 GHz is available everywhere — it depends on per-region certification. We confirm the chipset, whether TWT is actually implemented, and the FCC/CE status for any 6 GHz operation.

FAQ
What's the battery benefit of Wi-Fi 6 for IoT?
Target Wake Time (TWT) lets a device schedule when it wakes the radio instead of staying alert, cutting power draw substantially on sensors and trackers. Confirm the module actually implements TWT, since not all do.
Does Wi-Fi 6E need extra certification?
Yes. 6 GHz (6E) operation requires separate FCC and CE authorization, and it's only legal where certified. A module advertising 6 GHz is only useful if it's approved for your market.
