Featuring Ubiquiti INVICTUS?custom silicon for 2+ million packets-per-second processing, the airFiber?24HD is ideal for outdoor, PtP bridging and backhaul applications requiring maximum performance. Revolutionary Performance Featuring the world?s best unlicensed-band spectral efficiency at 15.9 bps/Hz, the airFiber?24 HD supports the dense modulation rates, up to 256QAM, that are required for high data rates, up to 2 Gbps. Proven Links: 20+ km The airFiber?24 HD features the most powerful automatic compensation for path loss degradation due to rain fade, so it provides the best range ? up to 20+ km ? among 24 GHz products and allows for constellation threshold extension. Low-Latency Carrier Backhaul The airFiber?24 HD supports FDD (Frequency Division Duplexing) in full-duplex mode for 0.2 millisecond latency, resulting in increased efficiency for carrier-class network backhauls. 24GHz Unlicensed Band The airFiber?24 HD operates in worldwide, license-free, 24 GHz frequencies. Users can deploy airFiber?24HD almost anywhere they choose (subject to local country regulations https://www.ubnt.com/airfiber/airfiber24-hd/ airFiber (Wireless Backhaul)
