Ubiquiti airMAX airCube ISP Wi-Fi Access Point (ACB-ISP)

The Ubiquiti ACB-ISP is a compact, highly cost-effective 2.4 GHz wireless access point purposefully engineered for Wireless Internet Service Providers (WISPs) to deploy as a standard residential subscriber router. Housed in a minimalist, space-saving black cube enclosure, this efficient device bridges the gap between outdoor customer premises equipment (CPE) and the indoor home network.

By managing both local subscriber Wi-Fi and the main link power from a single desktop node, the airCube minimises consumer structural clutter while simplifying on-site installations.

Integrated 24V Passive PoE Passthrough Routing

The core architectural advantage of the ACB-ISP is its integrated dual-voltage power injection framework, which eliminates duplicate internal power cabling:

• Single-Adapter Power Loop: When the access point is supplied with 24V passive PoE via LAN Port 1, it natively activates a controllable 24V passive PoE output loop directly down its dedicated WAN port. This permits a single ethernet cable to pass cleanly through the wall, powering upstream outdoor airMAX sector radios or LTU client receivers.

• Micro-USB Input Adaptability: For standalone local routing deployments where upstream power delivery is unnecessary, the chassis can be powered independently via a basic 5V DC Micro-USB input terminal (requiring a standard 2A adapter, available separately).

Smart 2.4 GHz Carrier Wireless Architecture

Optimised for long-range penetration through interior residential wall structures, the wireless grid delivers stable connectivity for everyday household media tasks:

• 2x2 Spatial MIMO Streams: Leverages legacy 802.11n Wi-Fi 4 standards across a dual-stream antenna matrix, supporting line-of-sight over-the-air speeds up to 300 Mbps.

• 4 dBi High-Mass Internal Antenna: Features an innovative internal omnidirectional aerial cluster tucked inside the upper dome. This design shapes a uniform signal sphere to eliminate common horizontal dead zones without sticking out visually.

Network Interface & Power Distribution Layout

The bottom terminal block groups four independent 10/100 Fast Ethernet ports mapped for straightforward service separation:

Centralised UISP Cloud Control for Operators

• Zero-Touch Mass Management: Engineered specifically to integrate with the Ubiquiti Internet Service Provider (UISP) application platform. Network operators can remotely configure, monitor, update, and reboot thousands of active subscriber access points across a country from a single dashboard.

• Direct Mobile App Provisioning: Field technicians can execute rapid on-site setup using an intuitive mobile application for iOS and Android. This links directly to the airCube via a secure, local setup Wi-Fi broadcast to verify line status in moments.

• Ambient Ground Glow Status Bar: The base of the cube features an elegant, soft white LED status strip. This provides clear visual diagnostic confirmation of system health without distracting customers in dark rooms.
