Ubiquiti Networks introduces the airFiber® AF-4X, Ubiquiti's first licensed spectrum radio designed for the public safety sector. It meets the growing need of broadband capacity and optimizes use of the 4.9 GHz radio band with its industry-leading spectral efficiency and TDD throughput. The AF-4X allows you to customize airFiber backhaul links or upgrade existing Rocket® Point-to-Point (PtP) links.
Designed for the Public Safety Market
Deploy the high-performance and reliable AF-4X for municipal applications, including police, fire, and emergency medical services.
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, 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.
4 GHz Backhaul
Mission-Critical Communications
The AF-4X covers the 4.9 GHz spectrum for public safety. Additional frequencies, from 4.7 GHz to 4.9 GHz, are supported in Europe and other regions (subject to local country regulations).
The AF-4X uses a proprietary radio communications protocol with AES-128 encryption to help ensure communication channels are secure.
Ultra-Low Latency with HDD Technology
The AF-4X is designed to provide the highest TDD throughput and lowest latency available using proprietary Hybrid Division Duplexing (HDD) technology.
Optimal Operation and Channel Configuration
The AF-4X supports up to 11 different channel width sizes to suit your deployment needs. You can configure independent TX and RX channel frequencies and place them anywhere within the radio band, and the channel centers are selectable in 1 MHz increments.
You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.
Co-Location
With space at a premium, the importance of being able to co-locate equipment is becoming an essential attribute for modern wireless networks. The AF-4X is engineered to permit multiple radios to operate side by side, allowing maximum spectral efficiency.
GPS Synchronization
Precise GPS frame synchronization enables co-located AF-4X 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 AF-4X radio design has an ultra-clean transmitter output, reducing broadband noise, facilitating co-location, and enabling higher-order modulations like 1024QAM for greater throughput.
Deployment Flexibility
The AF-4X supports ± 45° slant polarization for improved noise immunity and Signal-to-Noise Ratio (SNR). The compact form factor of the airFiber X allows it to fit into the radio mount of Ubiquiti antennas, so installation requires no special tools. The airFiber X antennas are purpose-built with 45° slant polarity for seamless integration with the airFiber AF-4X.
