MAC address vendor

U4EA Technologies — 2 prefixes (MA-L)

Primary prefix
00:15:93
Block
MA-L

Summary

// what this is
U4EA Technologies is registered to MAC prefix 00:15:93 and 1 more in the IEEE OUI database. When a device's MAC address begins with 00:15:93, that block was registered by U4EA Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Devices presenting either prefix are most likely legacy Fusion Series gateways or U4EA Wireless controller hardware; given the likely-defunct company status, treat as unsupported legacy CPE for security purposes.

About this vendor.

Updated  ·  Confidence: Medium

A MAC address beginning 00:15:93 or 00:1A:BC identifies U4EA Technologies hardware — most likely a Fusion Series business gateway or a U4EA Wireless mobility-controller product, rather than a single-purpose consumer device.

U4EA Technologies held two separate IEEE MA-L registrations under near-identical company names: U4EA Technologies Inc. (Fremont, CA, US) for 00:15:93, and U4EA Technologies Ltd (Bristol, GB) for 00:1A:BC — reflecting parallel US and UK entities rather than a single-country shell registration.

The company shipped Multi-Service Business Gateways (MSBG) under the Fusion Series name (Fusion 200/400/420), converging VoIP, data, and video access, plus carrier-grade signaling gateways for legacy-to-NGN interconnect. A separate U4EA Wireless line offered WiFi mobility-controller, GateD routing/switching, and WPA wireless-controller switching software.

Company status is uncertain. An aggregator (Tracxn) indicates U4EA Technologies is no longer active; that single aggregator claim is not corroborated by a primary source, so treat it as directional, not confirmed. Separately, U4EA itself acquired NextHop Technologies (a WiFi access-point and controller software maker) in May 2008 — which is what explains the U4EA Wireless GateD routing/switching line; that acquisition says nothing about U4EA's own status. No CVE or security advisory was found for any Fusion Series or U4EA Wireless product.

IEEE's public OUI data does not publish assignment/registration dates for either prefix; no date is asserted here.

Company status
Likely inactive [Likely] — tracxn.com (single aggregator source; not primary-corroborated)
Device types
Business VoIP/data/video converged access gateway (MSBG), carrier signaling gateway, WiFi mobility controller [Confirmed] — ciol.com, channelfutures.com, lightreading.com
Notable products
Fusion Series (Fusion 200/400/420); U4EA Wireless (mobility controller, GateD routing/switching, WPA wireless controller switching software) [Confirmed] — ciol.com, channelfutures.com
Verified prefixes
00:15:93, 00:1A:BC (both MA-L) [Confirmed] — IEEE the IEEE MA-L registry, maclookup.app
Registration dates
Unknown — IEEE publishes no MAC/OUI assignment dates [Confirmed] — IEEE the IEEE MA-L registry column set (Registry, Assignment, Organization Name, Organization Address only)
Security context
No CVE or advisory found for Fusion Series or U4EA Wireless products [Unknown]
Related vendors
None identified beyond the two U4EA Technologies registrant entities themselves
Analyst note
Two OUIs registered to closely related US/UK entities under the same brand — treat as one vendor for classification purposes; company status is likely defunct, so devices presenting these prefixes are most plausibly legacy CPE.
