The airCube ISP: The Smart Solution for WISP Customer Installations
The Ubiquiti airCube ISP is more than just a simple WiFi Router. It is a well-thought-out tool developed specifically for the needs of Wireless Internet Service Providers (WISPs). Its main task: to provide your customers with a reliable 2.4 GHz WiFi Network while optimizing your installation and maintenance processes. The compact design and intuitive operation make it the first choice for a professional and clean customer installation.
Ingenious PoE Passthrough: Fewer Cables, More Efficiency
The absolute killer feature of the ACB-ISP is the PoE passthrough function. If the airCube itself is powered via 24V PoE, it can pass this voltage directly to another device on its WAN port. In practice, this means: you connect the airMAX receiving Antenna on the customer's roof to the WAN port of the airCube inside the house. The Access Point then not only supplies the living space with WiFi but also powers the Antenna. A single cable, a single Power Supply – it doesn't get cleaner or more efficient than that.
Central Management with the UISP App
Forget time-consuming trips to the customer for simple configuration changes. The airCube ISP integrates seamlessly into the powerful and free Ubiquiti ISP Management Platform (UISP). Using the UISP App, you can set up the airCube ISP, monitor its status, apply firmware updates, and diagnose errors – all remotely from your office. This not only saves time and money but also increases customer satisfaction through quick response times.
FAQ: Your Questions About the Ubiquiti ACB-ISP Answered
We've summarized the most common questions for you: The airCube ISP is primarily intended as a cost-effective WiFi Access Point for end customers of WISPs. It is ideally powered by 24V passive PoE but can also use a 5V Micro-USB power adapter (not included). Unlike the airCube AC, it operates exclusively on the 2.4 GHz band (WiFi 4) and has 10/100 Mbps ports. Setup is very easy via the UISP app and a QR code scan. Important: The airCube ISP is not compatible with the UniFi controller but belongs to the airMAX/UISP family.
Strengths & Notes at a Glance
- Pro: Extremely cost-effective, ideal for mass rollouts by ISPs.
- Pro: Ingenious PoE passthrough feature for powering an external airMAX CPE, which massively reduces installation effort.
- Pro: Fully remotely manageable via the free UISP platform, which lowers operating costs through fewer technician visits.
- Pro: Compact, unobtrusive design that integrates well into living spaces.
- Note: Outdated Network technology (WiFi 4, 2.4 GHz, 10/100 Mbps ports), a bottleneck for internet connections over 100 Mbps.
- Note: Forums report occasional stability issues that may require a restart.

Frequently Asked Questions (FAQ)
What is the primary use of the Ubiquiti airCube ISP?
The airCube ISP is specifically designed as a cost-effective WiFi Access Point for Internet Service Providers (especially WISPs). It is installed at the end customer's premises to provide their home with WiFi and can simultaneously power the external receiving antenna (an airMAX CPE) via PoE.
How is the airCube ISP powered?
There are two options: Either via a 5V Micro-USB power adapter (not included) or, the preferred method, via 24V passive Power over Ethernet (PoE) on LAN port 1. These PoE Injectors / Power Supplies are a core part of the setup.
What is the difference between the airCube ISP (ACB-ISP) and the airCube AC (ACB-AC)?
The main difference is the WiFi technology. The airCube ISP, one of the key 2.4 GHz Components from Ubiquiti Networks, operates only on the 2.4 GHz band with the 802.11n standard (max. 300 Mbps) and has 10/100 Mbps ports. The airCube AC is a dual-band device that also supports the 5 GHz band with the faster 802.11ac standard (max. 867 Mbps) and features Gigabit Ethernet ports.
How do I set up the airCube ISP?
The easiest way to set it up is through the Ubiquiti UISP mobile app. You connect to the airCube's WiFi, scan the QR code on the bottom of the device, and follow the in-app instructions to configure the device, such as setting the WiFi name (SSID) and password, and selecting the operating mode (Router or Bridge).
How does the PoE passthrough on the airCube ISP work?
When the airCube ISP itself is powered by a 24V PoE Injector on LAN port 1, it can output this voltage on its WAN port. This means you can run an Ethernet Cable from the airCube's WAN port to an external Ubiquiti antenna to supply it with power and data, eliminating the need for a second Power Supply.
Can I manage the airCube ISP in a UniFi network?
No, the airCube ISP is part of the airMAX and UISP product family and is managed exclusively through the UISP platform or its own web interface. It is not compatible with the UniFi Controller, which manages devices like UniFi Access Points and the UniFi Switch.
