Ubiquiti Networks continues to disrupt the wireless broadband market with revolutionary technology at breakthrough pricing by introducing the airFiber® X, a modular airFiber radio system that will serve a wide range of frequencies and is designed to be compatible with a variety of Ubiquiti® antennas.
Building upon the proven design of the airFiber system, the airFiber X allows you to customize airFiber backhaul links or upgrade existing Rocket Point‑to‑Point (PtP) links.

Engineered for Performance

Ubiquiti’s INVICTUS™ custom silicon and proprietary radio architecture are designed specifically for long-distance, outdoor wireless applications.
Our INVICTUS core communications processing engine surpasses all of the limitations inherent to generic Wi-Fi chips to provide superior performance, long-range capability, DFS flexibility, and higher delivered throughput.
The airFiber X features industry‑leading spectral efficiency of up to 17.1 Mbps/MHz, line‑rate data packet processing of up to 687 Mbps of real data throughput, and innovative
xtreme Range Technology (xRT™) for up to 200+ km in range.

Ultra-Low Latency with HDD Technology

The airFiber X is designed to provide the highest TDD throughput and lowest latency available using proprietary Hybrid Division Duplexing (HDD) technology.


With tower space at a premium, the importance of being able to co-locate equipment is becoming an essential attribute for modern wireless networks. The airFiber X is engineered to permit multiple radios to operate side by side, allowing maximum spectral efficiency.

GPS Synchronization

Precise GPS frame synchronization enables co-located airFiber X radios to transmit and receive data without interfering with each other, enabling better frequency reuse and increased network stability.

Clean Power Output

Using advanced digital signal processing, the innovative airFiber X radio design has an ultra-clean transmitter output, reducing broadband noise, facilitating co-location,
and enabling higher-order modulations like 1024QAM for greater throughput.

Optimal Operation in Unlicensed Bands

Channel width flexibility* allows independent TX and RX channel frequency configurations anywhere within the radio band to avoid local interference, and the channel centers are selectable in 1 MHz increments.
• AF-2X/AF-3X 3.5, 5, 7, 10, 14, 20, 28, 30, 40, 50, or 56 MHz
You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.

* Channel widths may vary according to country/region regulations.
