When Gigabit isn't enough: The Power of airFiber 24 HD
The Ubiquiti airFiber 24 HD is no ordinary backhaul. While the standard airFiber 24 already delivers impressive speeds, the HD version is the true powerhouse of the series. From the outside, it may look similar, but inside, an even more powerful version of the Ubiquiti INVICTUS™ Processor is at work. The 'HD' here stands for 'High Density' and makes the decisive difference: The modulation. Unlike the standard model, which goes up to 64QAM, the HD version masters an impressive 256QAM modulation. This means it can pack significantly more data packets into the same radio wave, leading to a massive aggregated throughput of over 2 Gbit/s. If you need to connect enterprise locations and every bit of speed truly counts, the AF-24HD is your first choice.
Perfect for the City: 24 GHz and FDD Technology
In densely populated urban areas, the 24 GHz band is a true blessing, as 5 GHz bands are often overloaded and unusable. The AF-24HD optimally utilizes this frequency. Another decisive advantage is the use of two separate Antennas – one transmits, the other receives. Thanks to this physical separation and FDD technology (Frequency Division Duplex), there are no waiting times when switching between sending and receiving. The result is extremely low latency, giving you the feeling of a direct cable – ideal for time-critical applications and a smooth Network.
Range and Robustness: Even in Wind and Weather
Like all 24 GHz systems, the HD version is subject to physics, especially the so-called 'Rain Fade'. It is best suited for distances up to 10 km, but can also cover up to 20 km under optimal weather conditions. Thanks to improved receiving Antennas with higher gain, it offers slightly more reserves in rain than the standard model. The robust construction withstands wind loads of up to 200 km/h, and the extended operating temperature range from -40°C to +55°C ensures reliable performance under extreme conditions.
Your Network on the Next Level: Applications and Advantages
The Ubiquiti airFiber 24 HD is the ideal solution for anyone placing the highest demands on their wireless point-to-point connection. Whether you want to connect multiple enterprise locations with a high-speed link, transfer large amounts of data, or build a redundant backbone connection – the AF-24HD delivers the necessary performance. It is an excellent alternative to fiber optics where laying a cable is not practical or too expensive. With this solution, you can build reliable WiFi Bridge Sets that exceed your expectations and future-proof your Network.
