How far can you you go with certain airFiber models?

The airFiber line has come a long way since the first incarnation back in 2012, now expanding beyond 24GHz with 11GHz, 60GHz, 5GHz, 2GHz, 4GHz, 3GHz and more. However, with the complication of different frequencies comes a multitude of minimum and maximum distances that these devices can work at.

Distance recommendations

Rain fade considerations

While the above maximum distances look good on a spec sheet, in the real world some of these are only achievable in lab conditions. For example, in UK weather the airFiber 24HD as a real world range of 8km without dropping the link completely.

The lower the frequency the less rain fade you'll experience.
