Using the AF-11FX-L airFiber 11FX Low-Band Licensed Backhaul Radio from Ubiquiti Networks to connect the Ubiquiti AF-11G35 antenna or a variety of third party antennas using the optional adapter kit. Regardless of the antenna you're connecting to, this radio offers enhanced connectivity using the licensed 11 GHz radio band. By utilizing this radio band clients benefit from enhanced wireless connectivity complete with higher data transfer rates at greater distances.

This Ubiquiti Backhaul Radio can be configured to use either single (SISO) or multiple (MIMO) connectivity while a network admin can configure the transmit and receive signals to reside on separate channels to further improve network performance. Installation is simple as the radio supports both DC and PoE power and comes with silicone boots to help protect against the elements when installed outdoors.

  • True Full-Duplex Design

The AF-11FX offers a true FDD solution that fully satisfies all licensing requirements for the 11 GHz band.

  • Ultra-Low Latency

Overall customer experience and system capacity is enhanced with FDD performance.

  • Enhanced Robustness

The AF-11FX features a unique, built-in, rain-fade mitigation strategy for increased link robustness.

  • Extended Range

The RF power amplifiers feature a unique bias scheme, allowing high-order constellations at longer ranges.

  • Optimized Channels

The airFiber AF-11FX can use single (SISO) or bonded (MIMO) channels, depending on your specific licensing requirements. The AF-11FX also features different channel width sizes to suit your deployment needs, and you can independently configure TX and RX channel frequencies.

  • Reconfigurable Duplexers

The AF-11FX features a unique modular duplexer design to suit multiple frequency configurations. Each AF-11FX radio can be configured to support any allowable frequency by simply changing the duplexers for high-band or low-band use in the 10.7 - 11.7 GHz allocation. Each duplexer has a low channel and a high channel that can be configured by simply reversing the position of the duplexer.

  • High Performance

The compact AF-11FX supports high-order constellations - up to 1024 QAM - allowing it to deliver enhanced spectral efficiency.

  • Power Source Options

Support for PoE or DC power gives you the flexibility to power the AF-11FX separately from Ethernet traffic.

• PoE power can be supplied on the DATA port, using the provided PoE adapter.
• DC power can be supplied using the terminal block.

  • Versatile, Ruggedized N-Type Connectors

N-connectors allow the AF-11FX to be used with either the Ubiquiti AF-11G35 antenna or a variety of commonly available antennas. Specially designed silicone boots provide a weatherproof barrier against dust and moisture.
