Description

The airFiber AF-4X 4 GHz Carrier Backhaul Radio from Ubiquiti Networks is designed for long-range, Point-to-Point (PtP) backhaul links. It features a high TDD throughput and Hybrid Division Duplexing (HDD) technology that helps the device achieve low latency. The airFiber 4X also allows users to customize backhaul links or upgrade existing PtP links.

The airFiber AF-4X operates using the 4 GHz frequency band and features a range of 656,168' / 200,000m. Included with this device is a GPS antenna mount, an external GPS antenna, a metal strap, two cable ties, a 24V/1A airFiber PoE adapter with a mounting bracket, and a power cord.

Performance

Ubiquiti's INVICTUS silicon and radio architecture are designed specifically for long-distance, outdoor wireless applications. Their INVICTUS core communications processing engine surpasses virtually all of the limitations inherent to generic Wi-Fi chips to help provide superior performance, long-range capability, DFS flexibility, and power output.

Backhaul

Deploy the 4 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.

Operation in Unlicensed Bands

Channel width flexibility (10/20/30/40/50 MHz) allows independent TX and RX channel frequency configurations virtually anywhere within the radio band to avoid local interference, 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

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.

Co-Location

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 256QAM for greater throughput.

Carrier Backhaul Radio

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.

Models: AF‑2X, AF‑3X, AF‑4X, AF‑5X

Engineered for Performance

Ubiquiti’s INVICTUS™ custom silicon and proprietary radio architecture are designed specifically for long-distance, outdoor wireless applications.

Deployment Flexibility

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, 4, 5 or 11 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.
