GooWi Wireless Technology Co., Limited — 4 prefixes (MA-L)

A MAC address starting with 38:D5:18, B4:84:D5, 14:2C:78, or 68:D6:ED belongs to GooWi Wireless Technology Co., Limited, a Shenzhen-based OEM whose registered IEEE MA-L blocks trace to Bluetooth Low Energy hardware — most identifiably the GWLE1010B BLE 4.1 module used in health/medical, security/proximity, sports/fitness, entertainment, HID, and smart-home products.

IEEE lists all four blocks under the exact organization name "GooWi Wireless Technology Co., Limited," registered to an address in Shenzhen's Futian District (Tairan Technology Park), Guangdong, China. A closely-named but distinct entity, "GooWi Technology Co.,Limited," separately holds a fifth block (64:72:D8) at a different Kwun Tong, Hong Kong address — treat it as a related but separate registrant, not an interchangeable alias.

Holding four separate OUI assignments plus an identifiable, datasheet-documented product (the GWLE1010B BLE module) lifts GooWi Wireless Technology above a bare single-OUI shell registration. An independent FCC equipment filing (grantee code 2AFJJ) shares the exact street address of two of the OUI blocks, corroborating that the registrant is an operating company rather than a name-only registration.

No CVEs or public vulnerability disclosures were found for GooWi or the GWLE1010B in a targeted search — an absence of findings, not a confirmed clean record. FCC filing dates (grantee assigned 2015-08-03, device filed 2015-08-10) are regulatory-database dates, not IEEE OUI assignment dates; IEEE publishes no registration date for any MAC prefix. A separate brand, "Goowls" (WiFi security cameras), is unrelated and should not be conflated with GooWi.
