There are two airFiber models available for the 5 GHz spectrum. The model, AF5, features the popular mid-band frequencies, which are freely used in many parts of the world. The high-band model, AF5U, which can operate in the 5.7 - 6.2 GHz bands, has robust filtering to enable co-location with devices operating in the lower 5 GHz bands while allowing operation at a higher output power in many areas of the world.

Superior Processing Ubiquiti Networks introduces our proprietary INVICTUS™ core communications processing engine. The speed, power, and efficiency of this integrated circuit enhances the performance of airFiber AF5/AF5U. Efficient Use of 5 GHz Band airFiber AF5/AF5U features 1 MHz center channel resolution with market-leading Power Envelope Tracking technology. airFiber AF5/AF5U accurately and continuously controls transmit power relative to the band edge. The power level automatically tracks to optimize performance near band edges, allowing you to choose the part of the band with the least interference. Long-Range Links Newly developed for airFiber AF5/AF5U, the patent-pending xRT feature uses an innovative, adaptive multi-channel coding scheme to enhance radio transceiver performance, thereby maximizing your link budget and spectrum utilization – while still maintaining regulatory compliance. This results in links that can span distances from 10 m up to 100+ km. Quick and Easy Installation The unique sliding-clamp design of airFiber AF5/AF5U allows mounting hardware to be pre-assembled prior to installation – no more dropped screws at the top of the tower. As an added convenience, the drop-in cradle mount design allows the installer to attach mounting hardware to the pole without having to support the weight of the airFiber radio during installation.
