Fiber-Optic Performance Without Cables: Your 2 Gbps Backhaul Solution
Imagine being able to connect two buildings or a remote location at a speed of over 2 Gbps without having to lay a single meter of fiber optic Cabling. That's exactly what the Ubiquiti airFiber 24 HD enables you to do. This powerful point-to-point wireless bridge was specifically developed as a 'backhaul' to create a stable and extremely fast Network backbone. Whether for connecting a company building, providing a rural area with fast internet, or as a redundant connection – the AF-24HD replaces expensive leased lines and offers performance otherwise only achievable with physical cables.
License-Free and Powerful: The 24 GHz Band Optimally Utilized
One of the biggest advantages of the airFiber 24 HD is its operation in the globally license-free 24 GHz band. For you, this means: no ongoing costs for frequency licenses and no bureaucratic hurdles. You can put your high-speed connection into operation immediately. Ubiquiti masterfully utilizes this frequency band by employing advanced technologies such as high 256QAM modulation and a channel bandwidth of 100 MHz. The result is a highly efficient and low-interference transmission that exploits the full potential of the frequency spectrum.
Built for Extremes: Military Standard Robustness Meets Smart Technology
An outdoor Network solution must be absolutely reliable. The airFiber 24 HD was therefore designed for maximum reliability. Its mechanical assembly is not only tested according to MIL-STD-810G but also survives wind speeds of up to 200 km/h. But the true strength lies in the details: intelligent compensation for 'Rain Fade' (signal loss due to rain) ensures that your connection remains stable even in bad weather. This combination of physical robustness and smart software makes the AF-24HD one of the most reliable WiFi Bridge Sets on the market.
Maximum Efficiency: FDD, HDD, and GPS-Sync for an Interference-Free Connection
The airFiber 24 HD offers you the choice between two duplex methods to perfectly adapt the connection to your needs. The FDD mode (Frequency Division Duplex) enables true full-duplex operation for highest throughput and lowest latency, ideal for performance-critical applications. The proprietary HDD mode (Hybrid Division Duplex), on the other hand, offers higher stability over very long distances. Additionally, the integrated GPS synchronization ensures that multiple airFiber systems can be operated at the same location without mutual interference – a crucial feature for professional Network infrastructures in the airFiber category.
Strengths & Notes at a Glance
- Pro: Extreme bandwidth (2+ Gbps) and range (20+ km) replace expensive fiber optic or leased lines.
- Pro: Operation in the globally license-free 24 GHz band significantly reduces total operating costs (no frequency fees).
- Pro: High reliability due to robust construction (military standard tests) and advanced compensation for signal loss due to rain.
- Pro: Extremely low latencies and minimized interference thanks to FDD/HDD duplexing and GPS Synchronization (GPS Trackers).
- Note: The 24 GHz band is naturally susceptible to extreme weather events such as heavy rain, which may require a backup link.
- Note: An absolutely clear and uninterrupted line-of-sight is mandatory for optimal performance.

Frequently Asked Questions (FAQ)
Do I need a license to operate the airFiber 24 HD?
No, the airFiber 24 HD operates in the globally license-free 24 GHz frequency band. You can operate the device without special permits or additional license costs, but you must observe local country regulations.
What is the difference between the AF-24 and the AF-24HD models?
The AF-24HD model offers a higher maximum throughput of 2 Gbps, a greater range of over 20 km, and supports higher modulation rates such as 256QAM thanks to improved electronics and a more robust housing for the airFiber.
Can an airFiber 24 HD be connected to a regular airFiber 24?
Yes, a connection between an AF-24 and an AF-24HD is possible. However, the maximum throughput of the entire airFiber connection will be limited by the performance of the weaker AF-24 device.
What do FDD and HDD mean for this device?
FDD (Frequency Division Duplex) is a full-duplex mode that uses separate frequencies for transmitting and receiving to achieve maximum bandwidth and minimal latency. HDD (Hybrid Division Duplex) is a mode developed by Ubiquiti Networks that increases stability over long distances.
How is the airFiber 24 HD powered?
Power is supplied via passive Power over Ethernet (PoE). A special 50V, 1.2A Gigabit PoE Injector is included and powers the airFiber device via the Cabling network cable.
How difficult is the installation and alignment?
Installation requires mast Mounting Systems and precise alignment. Ubiquiti Networks simplifies this with an integrated LED indicator for signal strength, an audio tone for alignment assistance, and the intuitive airOS configuration interface. A clear line of sight is absolutely essential for optimal Network performance.
