UBIQUITI airFiber® 5X HD 5 GHz 1Gbps Carrier Backhaul Radio AF-5XHD

Overview

Ubiquiti Networks continues to disrupt the wireless broadband market with revolutionary LTU technology that breaks through the limitations of 802.11 Wi-Fi technology. Designed for use in the 5 GHz frequency band, the new airFiber AF-5XHD is Ubiquiti's first LTU radio, offering greater channel bandwidths of up to 100 MHz, and more advanced RF components.

Pair the AF-5XHD with a compatible Ubiquiti® airFiber X antenna or RocketDish ™ antenna for a complete 5 GHz Point-to-Point (PtP) solution.

An IP67 upgrade kit is included to provide enhanced protection from dust and water.

Engineered for Performance

Designed specifically for the Wireless ISP industry from the ground floor up, the AF‑5XHD’s custom LTU silicon and radio architecture provide 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 industry leading 21.2 bps/Hz spectral efficiency*, line‑rate data packet processing for up to 1.34 Gbps of real data throughput*, and innovative xtreme Range Technology (xRT ™).

* Assuming 4096QAM, available with a future firmware upgrade.

Key Features

The AF-5XHD offers the following advanced features:

• Programmable Transmit Power The radio's transmit power level can be programmed up to +29 dBm.

• Programmable Duty Cycle (GPS synchronized frames) The AF-5XHD allows configuration of asymmetric TX and RX duty cycles. TX ratios include 25%, 33%, 50%, 66.7%, and 75%.

• Configurable GPS Synchronization The AF-5XHD offers configurable support for 2, 2.5, 4, and 5 ms frames. Timing is compatible with all other synchronous systems.

• Split TX and RX Frequency* The radio can operate on different frequencies for TX and RX, allowing great flexibility for interference avoidance.

• Split TX and RX Channel Bandwidth* Support for different channel bandwidths for TX and RX allows users to scale required data capacity more efficiently.

• Adaptive Modulation up to 1024QAM Adaptive modulation rates of up to 1024QAM (4096QAM with targeted upgrade) are supported.

• Dual Redundant Gigabit Ethernet Ports with PoE The AF-5XHD has two Gigabit Ethernet ports that can be used to provide redundant PoE power.

• OFDM and OFDMA Support* The radio offers flexible scheduling for 2, 4, or 8 subchannels.

• Bluetooth Wireless Configuration Use the built-in Bluetooth interface for wireless configuration.

• AlignLock™ Antenna Aiming Guard This alerts the user when the radio or antenna aiming is changed due to tampering, impact, or storm damage.

• User-Configurable Interference Mitigation Three user-selectable profiles support both high‑interference and greenfield deployments for robust, optimal performance.

• Redundant Images for Fail-Safe Configuration Creation of backup firmware images ensures fail-safe configuration and enhances reliability.

• Persistent Spectrum Analysis with Dedicated RX Perform real-time spectral analysis for the full band on live links without interrupting the link operation.

• Wide Voltage Range, Enhanced Surge Protection The AF-5XHD has an operating voltage range of 19‑50VDC  and provides enhanced surge protection.

* Available with a future firmware upgrade.
