airCube ACB-AC home access point
The Ubiquiti Networks airCube ACB-AC is a dual-band wireless access point built for home deployments. It runs 802.11ac with 2x2 MIMO to serve laptops, phones and smart devices across two radio bands. The compact unit is designed to interoperate with airMAX CPE equipment in a managed network. It suits installers who need a simple, cost-effective Wi-Fi layer for residential customers.
24 V PoE passthrough and four Gigabit ports
The enclosure includes integrated 24 V PoE passthrough so the access point can draw power and feed a downstream device from a single cable run. Four Gigabit Ethernet ports provide wired uplinks and local connections for switches, PCs or additional access points. The Super Antenna design extends coverage beyond a standard omni-pattern, reducing dead zones in typical home layouts. No separate power supply is required when a compatible PoE injector is used.
802.11ac throughput limits
The 2.4 GHz radio tops out at 300 Mbps and the 5 GHz radio at 866.7 Mbps under ideal conditions, so aggregate wireless throughput cannot exceed those PHY rates. Real-world speeds will be lower due to overhead, interference and client capabilities. The unit does not support newer Wi-Fi standards such as 802.11ax, so environments that require higher efficiency or multi-gigabit wireless will need different hardware. Buyers who need more than two spatial streams or 6 GHz operation should look elsewhere.

Questions about this item
Does the 802.11ac dual-band radio cap at 300 Mbps on 2.4 GHz and 866.7 Mbps on 5 GHz?
Yes, the 2.4 GHz band reaches up to 300 Mbps and the 5 GHz band up to 866.7 Mbps with 2x2 MIMO.
What physical space and mounting does the airCube ACB-AC require?
It has a compact design with four Gigabit Ethernet ports and integrated 24 V PoE passthrough for inline power.
How is the airCube ACB-AC installed and what step is often missed?
Connect the PoE injector to the 24 V PoE in port, then link the passthrough port to an airMAX CPE; the passthrough must be enabled for the CPE to receive power.
