Sichuan Tianyi Kanghe Communications Co., Ltd. — 5 prefixes (MA-L)

Sichuan Tianyi Kanghe Communications Co., Ltd. holds five IEEE MA-L (24-bit OUI) assignments — 18:AA:CA, 48:A7:3C, B0:AA:D2, B4:CF:E0, and F4:32:3D — all registered to the same street address in Jinyuan Town, Dayi County, Chengdu, Sichuan, China (No.198, Section 1, Xueshan / "Snow Mountain" Avenue, postal 611330). Consolidating the five prefixes into one vendor entry is more useful than five near-identical per-prefix pages. The company is a Chinese telecom-equipment supplier; secondary Chinese-language press describes it as a longtime shortlisted supplier to domestic telecom operators for enterprise broadband access, intelligent networking, mobile-signal deep-coverage, intelligent-vision, and fiber-optic connection equipment, and notes a Hong Kong subsidiary registration around January 2020. One data-integrity caveat matters for this entry: despite the shared "Sichuan Tianyi" branding and an identical registry street address, Kanghe appears to be a distinct legal entity from the already-enriched "Sichuan Tianyi Comheart Telecom Co., Ltd." (vendor-comheart) — a patent-litigation index lists the two as adverse parties — so these records must not be merged. That distinction is Likely rather than Confirmed because the primary litigation page returned HTTP 403 and only the search-snippet was observable. No official Kanghe corporate website was located, and no product-specific CVEs or firmware advisories were found.
