Hefei Radio Communication Technology Co., Ltd. — 5 prefixes (MA-L)

Hefei Radio Communication Technology Co., Ltd. (also styled "HF.Radio Communication Technology Co.,Ltd" in FCC filings; brand name "Radiotech") is a Chinese broadband equipment manufacturer headquartered at No. 108, YinXing Road, High-tech Development Zone, Hefei, Anhui Province, CN 230088. The company holds 5 MA-L (24-bit OUI) blocks in the IEEE registry: 14:82:5B, 30:44:87, 58:9B:F7, C8:AF:E3, and F4:95:1B. It was founded in 2003, is listed on China's NEEQ exchange (ticker: 836590), employs roughly 100–350 staff (sources vary), and carries 59+ patents. The company markets itself as a provider of broadband equipment for wired/fiber access (including DOCSIS 3.0/3.1 and GPON/ONU), Wi-Fi access points, home network gateway products, device management platforms, and smart-home integration. Its primary customers are ISPs and service providers who deploy residential CPE. FCC filings under grantee code 2A6PE confirm at least two FCC-certified products: the RTCD905-H6W4 (DOCSIS 3.0 residential gateway, dual-band 802.11ac/n, Zigbee/Bluetooth IoT integration, grant 2022-06-29) and the RTCD907H2W6 (DOCSIS 3.1 residential gateway, dual-band, grant 2025-04-24). The vendor site is http://www.radiotech.cn (connection refused at research time; domain confirmed via search and FCC records). No CVEs, threat-intelligence reports, or botnet associations specific to this vendor were found in open sources. The MAC OUI is a normal ISP-CPE profile: these prefixes will surface on residential gateways and Wi-Fi routers deployed by cable/fiber operators.

IEEE assignment

5 prefixes → Hefei Radio Communication Technology Co., Ltd., registered No.108 YinXing Road, High-tech Development Zone, Hefei, Anhui CN 230088, China [Confirmed] — cached the IEEE MA-L registry (IEEE MA-L)

Registry / block size

MA-L (24-bit OUI); 5 IEEE prefixes, ~16 million addresses each [Confirmed] — cached the IEEE MA-L registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools (e.g. maclookup.app citing "24 September 2011") is a database artifact, not an IEEE fact.

Registration date

Unknown — IEEE publishes no registration dates for MA-L OUI assignments; no date data is present in the cached registry CSV. Third-party "date registered" values (e.g. "24 September 2011" on maclookup.app) are database artifacts, not IEEE facts. [Unknown]

Security context

No CVEs, public vulnerability disclosures, botnet campaigns, or threat-intelligence reports specifically naming Hefei Radio Communication Technology or its products were found in open sources. Device profile is ISP-deployed residential gateway/CPE — the generic attack surface for this class (default credentials, UPnP exposure, outdated firmware) applies but no vendor-specific findings are confirmed. [Unknown — no vendor-specific findings]

Analyst note

A globally-administered Hefei Radio OUI identifies ISP-deployed residential CPE (broadband gateways, Wi-Fi APs). These prefixes are expected on cable/fiber customer-premises equipment in operator deployments. No known named threat associations; security posture should be assessed per device/firmware, not MAC prefix.
