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)
