Shenzhen RF-Link Technology Co., Ltd. — 12 prefixes (MA-L)

Shenzhen RF-Link Technology Co., Ltd. is a Baoan District, Shenzhen-based OEM radio-module maker holding twelve separate IEEE MA-L (OUI) block assignments, all registered to the same Xixiang Town, Baotian Road address. Twelve independent blocks is itself a company-substance signal: shell or one-off registrants rarely need more than a single OUI, while an active hardware vendor iterating across product lines exhausts address space repeatedly. Independent corroboration comes from an FCC equipment-authorization grant (ID 2AGQ3-8821) for a WiFi+Bluetooth combo module under Part 15 Single Modular Approval, which matches the company's claimed business of supplying WiFi, WiFi+BT, Bluetooth-speaker, NFC, GPS, and Zigbee OEM modules for integration into TVs, TV boxes, IP cameras, car electronics, tablets, and smart appliances. Third-party company-profile aggregators additionally describe a China New Third Board (NEEQ) public listing (stock code 834491) and named OEM customers, though those specific claims were not independently cross-checked against a primary Chinese corporate registry in this pass and are held at Likely confidence. One near-name false positive was identified and excluded: OUI 00:0B:49 belongs to "RF-Link System Inc." of Tainan, Taiwan — a different legal entity, not this vendor.

IEEE assignment

12 MA-L prefixes → SHENZHEN RF-LINK TECHNOLOGY CO.,LTD., registered Bldg 56A, 6/F, Baotian Rd 3, Xixiang Town, Baoan District, Shenzhen, Guangdong, CN 518000 (one later block lists 518100) [Confirmed] — IEEE the IEEE MA-L registry

Registry / block size

MA-L only (24-bit OUI); no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) matches found for this org [Confirmed] — IEEE the IEEE MA-L registry / the IEEE MA-M registry / the IEEE MA-S registry

Prefixes

34:75:63, 38:83:9A, 38:A2:8C, 58:B3:FC, 7C:C7:09, 84:20:96, BC:9D:42, C0:21:0D, C4:6E:7B, CC:79:CF, E0:85:9A, F0:85:C1 [Confirmed] — IEEE the IEEE MA-L registry, cross-referenced against maclookup.app

Registration date

Unknown — IEEE's public OUI CSV publishes no assignment-date field; third-party "date registered" values shown per-prefix on maclookup.app (e.g. 34:75:63 = 2019-04-19) are database-ingestion artifacts, not IEEE facts, and are not recorded here [Confirmed] — no source (absence documented)

Company substance

SUBSTANTIVE — live corporate web presence, 12 OUI blocks, and at least one public FCC grant for a WiFi+BT module (not a bare single-OUI shell) [Likely] — fccid.io/2AGQ3-8821, maclookup.app

Product line

WiFi access modules, WiFi+Bluetooth combo modules, Bluetooth speaker/box modules, NFC, GPS, and Zigbee OEM modules for digital products, car electronics, tablets, smart TVs/TV-boxes, IP cameras, and smart appliances

[Likely] — rocketreach.co company profile, corroborated in kind by the FCC WiFi+BT module grant

Corporate registry / listing

reported China New Third Board (NEEQ) public share-transfer listing, stock code 834491; founding year reported as 2005 [Likely, single-source aggregator, not cross-checked against a primary Chinese registry] — rocketreach.co, cnverify.com

Security context

no CVEs, advisories, or botnet/malware association found for this vendor or its modules in this pass; as an OEM radio-module supplier, downstream issues would typically surface under the integrator's brand rather than "RF-Link" [Unknown] — no source (absence documented)

False-positive exclusion

OUI 00:0B:49 = "RF-Link System Inc." (Tainan, Taiwan) is a different legal entity and is NOT part of this vendor's block set [Confirmed] — IEEE the IEEE MA-L registry

Master status

not present in this site's own enrichment records as of this cycle; queued via this site's own enrichment records [Confirmed] — enrichment repo state
