6Harmonics Inc — AC:EE:3B (MA-L)
Summary
- // what this is
- 6Harmonics is registered to MAC prefix
AC:EE:3Bin the IEEE OUI database. When a device's MAC address begins withAC:EE:3B, that block was registered by 6Harmonics — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- AC:EE:3B is a vendor-specific block, not a shared IEEE base; a MAC starting with it indicates 6Harmonics-manufactured rural/remote wireless radio hardware.
About this vendor.
A MAC address starting with AC:EE:3B belongs to 6Harmonics Inc, a Canadian wireless-equipment maker, typically seen on rural/remote broadband radio hardware rather than consumer devices.
6Harmonics is headquartered in Ottawa, Ontario, and designs UHF broadband wireless connectivity equipment built on TV White Space (cognitive radio) technology. Its product line pairs base-station sector radios with subscriber/client radios for last-mile rural internet access, and the company also markets units for public-safety and emergency-relief video links.
Only one IEEE registration was located for the company: the single MA-L block AC:EE:3B. No second OUI, and no MA-M or MA-S sub-block, turned up in the registries checked, so this is treated as a single-prefix vendor rather than a multi-block company like a large OEM.
No CVE, vendor security advisory, or vulnerability report tied to 6Harmonics or its radio products was found as of an August 2026 web search. That absence is a sourced negative, not a guarantee the hardware is unaffected by undisclosed issues.
