The airFiber AF-5XHD 5 GHz Carrier Backhaul Radio with LTU Technology from Ubiquiti Networks is designed for long-range, Point-to-Point (PtP) backhaul links. It features a high TDD throughput and Hybrid Division Duplexing (HDD) technology that helps the device achieve low latency. The airFiber 5XHD also allows users to customize backhaul links or upgrade existing PtP links. The airFiber AF-5XHD operates at 5 GHz and features a range of 62 miles. Included with this device is a GPS antenna mount, an external GPS antenna, a metal strap, two zip ties, a 24V/1A airFiber PoE adapter with a mounting bracket, and a power cord. The AF‑5XHD's custom LTU silicon and radio architecture provides breakthrough performance. Its core communications processing engine surpasses the limitations inherent to generic Wi-Fi chips to provide low latency, long‑range capability, DFS flexibility, higher constellations, and better power output, along with improved receive sensitivity. The AF-5XHD features 21.2 bps/Hz spectral efficiency, line‑rate data packet processing for up to 1.34 Gb/s of real data throughput, and innovative xtreme Range Technology (xRT)
The radio's transmit power level can be programmed up to +29 dBm
The AF-5XHD allows configuration of asy mmetric TX and RX duty cycles. TX ratios include 25%, 33%, 50%, 66.7%, and 75%
The AF-5XHD offers configurable support for 2, 2.5, 4, and 5 ms frames. Timing is compatible with all other synchronous systems
The radio can operate on different frequencies for TX and RX, allowing great flexibility for interference avoidance
Support for different channel bandwidths for TX and RX allows users to scale required data capacity more efficiently
Adaptive modulation rates of up to 1024QAM (4096QAM with targeted upgrade) are supported
The AF-5XHD has two Gigabit Ethernet ports that can be used to provide redundant PoE power
The radio offers flexible scheduling for 2, 4, or 8 subchannels
Use the built-in Bluetooth interface for wireless configuration
This alerts the user when the radio or antenna aiming is changed due to tampering, impact, or storm damage
