Fibocom holds 5 MA-L blocks registered as "Fibocom Wireless Inc." in Shenzhen, China. Verified samples include 64:F6:BB, 7C:B4:0F, 88:23:1F, B0:5A:44, and B4:36:A9. These OUIs appear on 2G–5G/LTE/NB-IoT cellular modules, laptop WWAN (M.2) modules, and Wi-Fi/BT modules embedded in laptops, IoT devices, routers, and industrial gear. Fibocom is a major laptop-WWAN and IoT cellular-module supplier, and its parts are widely used in Lenovo, Dell, and HP business laptops. The key analyst point mirrors Quectel and Telit: a Fibocom OUI identifies the embedded module, not the laptop or host brand — which is particularly relevant in laptops, where a Fibocom WWAN MAC sits alongside an Intel or Realtek Wi-Fi MAC inside the same chassis. For triage, a Fibocom OUI on a corporate network usually means a cellular-equipped laptop or an IoT/router WWAN module, so classify it as a cellular interface rather than a standalone device brand.
