AirFiber 5 GHz Full Duplex Point-to-Point Gigabit Radio

The airFiber^®5 is purpose-built for outdoor, PtP bridging and carrier-class network backhauls.

Designed for Freedom

airFiber operates in worldwide, license-free, 24 or 5 GHz frequencies. Anyone around the world can purchase and operate airFiber without any special permits, paperwork, or added licensing costs. Users are free to locate, deploy, and operate airFiber practically anywhere they choose (subject to local country regulations). Model Description Operating Frequency* AF5 Supports mid-band 5 GHz frequencies 5470 - 5950 MHz AF5U Supports high-band 5 GHz frequencies 5725 - 6200 MHz AF24 Supports 24 GHz frequencies 24.05 - 24.25 GHzInnovative Antenna DesignThe high-isolation, dual-antenna design is ideal for robust performance in the harshest RF noise environments.

Revolutionary Performance

Surpassing conventional wired backhauls, the airFiber^®5 delivers real throughput of up to 1.0+ Gbps.

Built for Speed and Range

airFiber delivers gigabit performance at 1.0+ Gbps for airFiber AF5/AF5U and 1.4+ Gbps for airFiber AF24. To put this in perspective, airFiber can transmit a 100 MB file in less than a second. Rivaling common broadband providers, airFiber download speed is up to 100x faster. With speed and throughput surpassing conventional wired backhauls, airFiber prevails over expensive and labor-intensive wired infrastructures.

Long-Range Links: 100+ km

Designed to be a high-performance backhaul, the airFiber^®5 performs at a range of up to 100+ km.

Low-Latency Carrier Backhaul

The airFiber^®5 supports FDD (Frequency Division Duplexing) in full-duplex mode for <1 ms latency, resulting in increased efficiency for carrier-class network backhauls.

5 GHz Unlicensed Band

The airFiber^®5 operates in worldwide, license-free, 5 GHz frequencies. Users can deploy airFiber5 almost anywhere they choose (subject to local country regulations).

Innovative Proprietary Modem Technology

Ubiquiti’s innovative proprietary modem technology was purpose-built to address the specific challenges of outdoor, PtP (Point‑to-Point) bridging and high-performance network backhauls. Every aspect of the radio has been carefully simulated and designed to optimize range, speed, and latency performance in the harshest RF noise environments.

Synchronous Data Transmission and Reception

Conventional wireless standards impose a latency by having to receive a packet before a packet is transmitted. airFiber can transmit data synchronously without any wait time. airFiber features traditional TDD and FDD modes of operation in addition to the proprietary Hybrid Division Duplexing (HDD) mode, which provides a breakthrough in range and spectral efficiency performance. Based on the ranging algorithm built into the air protocol, the airFiber radios use patent-pending HDD technology to calculate the propagation delay and know when each radio can transmit and receive, so they send packets in precise synchronization. Packet transmission latency is virtually eliminated.
