Product Information

airFiber 24 GHz Point-to-Point Gigabit Radio

The airFiber®24 is ideal for outdoor, PtP bridging and carrier-class network backhauls.

Superior 24 GHz Performance

airFiber AF24/AF24HD provides a breakthrough in 24 GHz backhaul performance. Systems for millimeter-wave frequencies typically experience RF losses when part of the RF is lost in the switches and filters.

The Ubiquiti R&D team eliminated such RF losses with separate yet integrated TX and RX antennas, so the link budget is robust and the airFiber AF24/AF24HD has better noise figure and higher transmit power efficiency.

Two airFiber 24 GHz Models

Two models deliver superior speed with spectral efficiency in the worldwide, license-free, 24 GHz radio band. The standard model, AF24, delivers up to 1.4+ Gbps throughput at a range of up to 13+ km.

The heavy-duty model, AF24HD, provides more throughput at up to 2 Gbps and increased range of up to 20+ km. It also includes a more rugged exterior with a metal reflector, to protect against nature’s harshest elements.

airFiber 24 is a truly revolutionary Point-to-Point wireless platform from Ubiquiti Networks. Housed in a compact, highly efficient form factor, airFiber delivers amazing wireless gigabit+ performance, low latency, and long range.

airFiber ushers in a new era in price-disruptive wireless technology ideal for carrier backhaul, building-to-building enterprise use, or public safety applications.

Efficient by Design

Every detail of airFiber was designed and engineered by the Ubiquiti R&D Team. From the silicon chip up to the innovative split-antenna architecture, the Ubiquiti R&D Team created airFiber to deliver superior throughput with efficiency.

airFiber was purpose-built to create a high performance backhaul. Plug and Play Deployment Based on Ubiquiti’s innovative and intuitive airOS®, the airFiber Configuration Interface enables quick deployment.

With installation efficiency in mind, the mechanical design allows easy installation by one person. A two-person installation crew can effectively install and align an airFiber link.

To fine-tune the alignment, the received signal levels can be conveniently accessed via any of these methods:

  • airFiber LED display
  • airFiber Configuration Interface
  • Audio tone feature

I have three pair of these that I use for outbuildings on our campus. I have had them up for 4 years plus without an issue. I would recommend them without reservation.
