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.

  • 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.

  • 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. 

  • 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.
