Quectel holds about 70 IEEE blocks registered as "Quectel Wireless Solutions Co.,Ltd." at 7th Floor, Hongye Building, No.1801 Hongmei Road, Xuhui District, Shanghai, China — the largest module-maker footprint in this batch. It holds both MA-L (24-bit) and MA-S (36-bit) blocks. Verified samples include 34:87:3D, 80:FB:F0, A4:86:AE, 50:80:4A, 90:A6:BF, and E8:24:04 (MA-L), plus an MA-S block beginning 8C:1F:64. These OUIs appear on 2G–5G/LTE/NB-IoT cellular modules, GNSS modules, and Wi-Fi/BT modules embedded in IoT devices, routers, trackers, and industrial and automotive equipment. Quectel is one of the world's largest cellular IoT module suppliers — Counterpoint Research reported it led the global market with roughly 37% of cellular IoT module shipments in Q1 2023. The key analyst point mirrors u-blox, Telit, and Sierra Wireless: a Quectel OUI identifies the embedded cellular or wireless module, not the host device's brand, so the same physical product can present a Quectel MAC while bearing another company's brand. For triage, a Quectel OUI in ARP/DHCP almost always means an IoT or M2M endpoint built around a Quectel module, so classify by device behavior rather than assuming a Quectel-branded product.

- Special note
- Module-maker "OUI ≠ host brand" case (like u-blox/Telit/Sierra Wireless). A Quectel OUI identifies the embedded module, not the host device's brand. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
