Universal Global Scientific Industrial (USI) — 23 prefixes (MA-L); module ODM, OUI ≠ host device brand
Summary
- // what this is
- Universal Global Scientific Industrial is registered to MAC prefix
00:10:C6and 22 more in the IEEE OUI database. When a device's MAC address begins with00:10:C6, that block was registered by Universal Global Scientific Industrial — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A USI OUI usually identifies the wireless module inside a device, not the device's brand — useful for 'what radio is in this thing,' not for whole-device branding.
About this vendor.
USI (Universal Scientific Industrial) holds about 23 MA-L blocks registered as "Universal Global Scientific Industrial., Ltd" at 141, Lane 351, Sec.1, Taiping Rd., Tsaotuen, Nantou, Taiwan, covering roughly 385.9 million addresses. Verified samples include 00:10:C6, 00:1E:37, 70:F3:95, 8C:3B:4A, 3C:E1:A1, and E0:2A:82. These OUIs appear on Wi-Fi/Bluetooth wireless modules, SiP (System-in-Package) modules, IoT, and electronics moduled or assembled for other brands — for example, 70:F3:95 has been observed on white-label Alfa USB Wi-Fi adapters. USI is a subsidiary of ASE Technology Holding. The key analyst point mirrors AzureWave and Murata: a USI OUI usually identifies the wireless module inside a device rather than the device's brand. For triage, a USI OUI usually identifies the wireless module inside a device, not the device's brand — useful for "what radio is in this thing," not for whole-device branding.
