Ubiquiti airFiber AF-2X 2.4 GHz Backhaul Radio – Single Unit
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.
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.
