AzureWave Technologies (Shanghai) Inc. — 2 prefixes (MA-L)

AzureWave Technologies (Shanghai) Inc. holds two IEEE MA-L blocks — 4C:AA:16 and 00:24:23 — both registered to the Shanghai-address entity at No.8 Lane 66, Chenbao Road, Malu Town, Jiading District, Shanghai (postal 201801). This registrant is a manufacturing site of the same corporate group as the Taiwan-headquartered AzureWave Technology Inc., a wireless-module ODM that is publicly listed on the Taiwan Stock Exchange (since 3 May 2011) and was established 13 April 2005. The two are distinct IEEE registrants and must not be conflated: the registry carries roughly 79 additional MA-L blocks under the differently-spelled "AzureWave Technology Inc." at a New Taipei City address, tracked separately. The Shanghai site is described as a factory producing wireless connectivity hardware — consistent with U.S. import customs records showing this specific entity shipping "wireless PCBA + housing" assemblies to a named U.S. buyer (Lexmark) across 2023–2024. AzureWave's core product line is Wi-Fi/Bluetooth combo modules and camera/image-processing modules sold through major distributors. One data trap to avoid: an "AzureWave Breach" cloud-security article concerns Microsoft Azure (CVE-2025-3928), not this hardware ODM — a naming coincidence, not a security finding for this vendor. No IEEE assignment dates exist for these blocks; IEEE publishes none.

IEEE assignment

2 prefixes → AzureWave Technologies (Shanghai) Inc., Shanghai, CN [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes. No MA-M or MA-S entries exist for this org [Confirmed] — IEEE the IEEE MA-M registry / the IEEE MA-S registry (neither contains an AzureWave entry). NOTE: IEEE public OUI data publishes NO assignment/registration date (columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Verified prefixes (both MA-L)

4C:AA:16, 00:24:23 [Confirmed] — IEEE the IEEE MA-L registry, corroborated by udger.com vendor lookup listing the identical two prefixes for this exact registrant

HQ / country

No.8 Lane 66, Chenbao Road (spelled "CHENGBAO RD." in one registry row), Malu Town, Jiading District, Shanghai, CN 201801 (registry address) [Confirmed] — IEEE the IEEE MA-L registry

Company status

active; Shanghai manufacturing site of AzureWave group [Likely] — atmosic.com partner page, EMIS company profile (single-source on the parent-subsidiary relationship, tagged accordingly)

Related entity

parent group AzureWave Technology Inc. (Taiwan; ~79 MA-L blocks; distinct registrant name/address, tracked separately) — established 13 Apr 2005, TWSE-listed since 3 May 2011, HQ Taipei [Likely] — emis.com, atmosic.com

Device types

wireless connectivity modules (Wi-Fi/Bluetooth combo modules), camera/image-processing modules [Likely] — azurewave.com, atmosic.com; customs data (importkey.com) shows this Shanghai entity exporting "wireless PCBA + housing" assemblies

Notable products / customers

wireless card assemblies shipped to Lexmark International (U.S.), 2023–2024 [Likely] — importkey.com (single-source customs record; underlying HS-code detail unavailable)

Website

https://www.azurewave.com (group site) [Confirmed] — azurewave.com

Security context

no CVE, breach, or vulnerability found specific to this OUI vendor. An "AzureWave Breach" article is about Microsoft Azure (CVE-2025-3928), unrelated — do NOT attribute it here. Treat posture as Unknown/no adverse findings (absence of evidence, not evidence of absence).

[Confirmed as a distinct false-positive] — ainvest.com (the unrelated article)

Assignment / registration date

Unknown — IEEE publishes no OUI assignment dates; the IEEE MA-L registry has no date column [Confirmed]

Analyst note

a 4C:AA:16 or 00:24:23 globally-administered address identifies genuine AzureWave-Shanghai hardware; do not conflate with the Taiwan registrant's ~79 blocks.
