The airFiber X features up to 17.1 Mbps/MHz of industry-leading spectral efficiency and uses proprietary Hybrid Division Duplexing technology to achieve the highest TDD throughput available for long-range, PtP links.
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 525 Mbps of real data throughput, and innovative xtreme Range Technology (xRT) for up to 200+ km in range.
The compact form factor allows the airFiber X to be used with airFiber Slant 45 antennas, or instantly upgrade a 5 GHz Rocket link that uses a RocketDish RD-5G30/RD-5G34* antenna.
Carrier Backhaul for the World
Deploy the 2.4, 3, or 5 GHz model that meets your specific spectrum requirements, anywhere around the world. The airFiber X features multiple channel width options to suit your deployment needs – up to 11 different channel sizes available for the AF-2X or AF-3X.
Optimal Operation and Channel Configuration
Channel width flexibility allows you to independently configure TX and RX channel frequencies and place them anywhere within the radio band to avoid local interference. You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.
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 256QAM for greater throughput.
The 2.4 GHz frequency band is free to use, worldwide; and with its proprietary protocol, the AF-2X increases both range and delivered throughput in this popular band.
The 3 GHz frequency band offers interference-free operation, enabling the AF-3X to provide a high-reliability backhaul solution, although a license may be required in some regions.
The AF-5X covers the entire, license-free, 5 GHz spectrum and includes DFS approval. Anyone around the world can deploy and operate the AF-5X in the 5 GHz range practically anywhere they choose (subject to local country regulations).
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
- AF-5X: 10, 20, 30, 40, or 50 MHz
You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.
