                                             airFiber X

                                                    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.

The airFiber AF-4X-US 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.


  • Engineered for Performance

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

  • 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.
