Home wireless access point

The Ubiquiti airCube ACB-AC-US is a dual-band 802.11ac access point rated at 1.14 Gbit/s aggregate throughput. It targets residential and small-business deployments that need wider coverage than a standard router provides. The integrated Super Antenna extends the signal footprint for indoor or outdoor mounting. Power-over-Ethernet passthrough simplifies cabling when paired with compatible equipment.

Check PoE and CPE compatibility

Verify that your existing airMAX CPE accepts 24 V passive PoE before ordering. The unit draws power through the Ethernet port and passes the same voltage to the downstream device. Confirm your network switch or injector supplies 24 V passive PoE on the correct pins. Without a matching power source the access point will not start.

UNMS Mobile app and PoE passthrough

The bundled UNMS Mobile application for iOS and Android handles initial setup, configuration changes and ongoing management from a smartphone. The 24 V PoE passthrough port eliminates the need for a separate injector when powering an airMAX CPE. This reduces hardware count and cable runs in typical customer-premises installations.

Questions about this item

Does the airCube ACB-AC-US come with a PoE injector or must I buy one separately?

The unit uses 24V PoE passthrough and can be powered by an airMAX CPE; a separate injector is not included.

Should I choose the 2.4 GHz or 5 GHz band for higher throughput on this model?

The 5 GHz radio reaches up to 866.7 Mbps while the 2.4 GHz radio tops out at 300 Mbps, so 5 GHz gives the higher speed.

What does the 1.14 Gbit/s headline rate mean for real-world throughput on this access point?

That figure combines both bands — 300 Mbps on 2.4 GHz plus 866.7 Mbps on 5 GHz — so a single client will see up to the per-band limit, not the combined total.
