Ubiquiti airFiber 2X (AF-2X)

The Ubiquiti airFiber 2X (AF-2X) is a high-performance, outdoor wireless backhaul radio designed to deliver long-distance connectivity using the 2.4 GHz frequency band. Built for professional-grade point-to-point (PtP) deployments, the AF-2X is part of Ubiquiti’s airFiber X series, offering impressive data throughput, advanced radio frequency (RF) features, and robust design to meet the needs of Internet Service Providers (ISPs) and enterprise networks seeking reliable broadband infrastructure in challenging environments.

Operating in the 2.4 GHz spectrum, the airFiber 2X is ideal for regions where this band is less congested or licensed for high-power use. It supports up to 500+ Mbps of real TCP/IP throughput, delivering strong performance even in scenarios where terrain or urban density can pose challenges to signal propagation. Leveraging the proprietary airFiber protocol, the AF-2X is capable of achieving low-latency transmission and optimized frequency use, which is critical for stable and high-capacity wireless backhaul links.

One of the major strengths of the airFiber 2X is its flexibility. It is designed to be paired with a wide range of Ubiquiti airFiber X antennas, including the RocketDish series, allowing installers to customize gain and beamwidth depending on the distance and environmental conditions of the link. This modularity ensures that the device can be tailored precisely for rural, suburban, or even industrial deployments.

The AF-2X also incorporates Ubiquiti’s GPS synchronization technology, which allows multiple radios on the same tower or site to operate without interfering with each other. By using GPS for timing, the radios can transmit in precisely coordinated slots, reducing self-interference and enabling frequency reuse—an essential feature for network scalability. It also includes a built-in spectrum analyzer and airView support, providing real-time visibility into the RF environment for optimal channel planning and interference management.

From a design standpoint, the airFiber 2X is engineered for rugged outdoor use. Its enclosure is built to withstand extreme temperatures, wind, and precipitation. The unit mounts easily on masts or poles, and its compact form factor simplifies installation even in tight or elevated spaces. It is powered via 24V passive PoE, combining data and power into a single cable for reduced infrastructure complexity.

Management and configuration are handled via a web-based interface, offering tools for alignment, performance monitoring, and firmware upgrades. The AF-2X is also supported in the UISP (Ubiquiti Internet Service Provider) platform for centralized management of multiple devices across wide-scale networks.

In summary, the Ubiquiti airFiber 2X (AF-2X) is a robust, flexible, and high-capacity 2.4 GHz wireless backhaul radio, making it an excellent solution for long-range point-to-point applications in underserved areas, industrial installations, or expanding wireless ISP infrastructure.
