The Revolution in the 5 GHz Band: Ubiquiti's LTU Technology
Forget the limitations of conventional Wi-Fi chipsets. The Ubiquiti airFiber 5XHD is based on the Custom LTU IC, a processor specifically developed for Outdoor Long-Range Applications. This LTU Technology is not compatible with standard WiFi or older airMAX products, as it was designed from the ground up for a single purpose: maximum performance. With adaptive modulation up to 4096QAM, the system achieves unprecedented spectral efficiency. This means for you: you transmit more data in less frequency space – a decisive advantage in highly congested areas. This component is a core piece for professional LTU Components in a Network.
Maximum Flexibility for your Point-to-Point Radio Link Connection
The AF-5XHD gives you full control. One of the most outstanding features is the ability to set transmit and receive frequencies and channel widths completely independently (Split TX/RX). Do you find an interference source on a specific channel? No problem, simply switch the transmit or receive channel without having to replan the entire connection. This flexibility makes the AF-5XHD the ideal choice for complex WiFi Bridge Sets and demanding environments where every frequency resource counts.
Built for Carriers: GPS Sync and Absolute Reliability
If you operate multiple radio links from a single mast, GPS Synchronization is indispensable. The AF-5XHD features an external GPS Antenna, allowing multiple devices to perfectly time their transmit and receive cycles. The result: no self-interference and stable, high-performance operation. The Hybrid Division Duplexing (HDD) technology developed by Ubiquiti also ensures extremely low latencies (1.5 - 3.5 ms), which is essential for VoIP, video streaming, and other time-critical applications. Together with the IP67 weather protection, this is a true Carrier-Class airFiber solution.
What you need for your airFiber 5XHD Long-Range WiFi Bridge
Please note that the AF-5XHD is a pure radio module. For operation, you absolutely need a suitable external Antenna, such as the Ubiquiti airFiber X Slant 45 or a RocketDish Antenna with the corresponding conversion kit. Installation requires expertise in RF planning and precise antenna alignment with a clear Line of Sight. Power is supplied simply via the included Gigabit PoE Injectors / Power Supplies. For configuration, in addition to the web interface, a practical Bluetooth interface is available for the UISP Mobile App.

Frequently Asked Questions (FAQ)
Can I use the airFiber 5XHD as a regular WiFi Access Point for my home?
No, absolutely not. The AF-5XHD is a highly specialized device for long-range point-to-point connections and cannot connect to standard WiFi clients like laptops or smartphones.
Is an Antenna included with the AF-5XHD?
No, the AF-5XHD is a radio module only. You must purchase a compatible external Antenna (e.g., a Ubiquiti airFiber X or RocketDish Antenna) separately to use the device.
What does "LTU Technology" mean?
LTU stands for "Long Term Ubiquiti" and is a proprietary radio technology developed by Ubiquiti. It was designed from the ground up for the needs of Wireless Internet Service Providers (WISPs) to overcome the limitations of standard Wi-Fi chipsets in terms of range, interference immunity, and efficiency. This technology is often found in advanced Network solutions.
Do I need a license to operate the airFiber 5XHD?
Generally not. The device operates in the license-free 5 GHz Components frequency band. However, local and national regulations regarding maximum transmit power (EIRP) and the use of DFS (Dynamic Frequency Selection) channels must be strictly observed.
What is the difference between the AF-5XHD and the older AF-5X?
The AF-5XHD is the successor and utilizes the more advanced LTU Components technology, while the AF-5X is based on the airMAX ac Components platform. The AF-5XHD offers a higher modulation rate (4096QAM vs. 256QAM), higher spectral efficiency, higher maximum throughput, and more flexibility in channel widths. The two models are not compatible with each other.
How is the airFiber 5XHD powered?
Power is supplied via passive Power over Ethernet (PoE). A suitable 24V, 1A Gigabit PoE Injector is included in the scope of delivery. The device is powered via the Ethernet data cable.
