Radar systems, which include weather radars, operate in the 5GHz frequency band, the same spectrum used by Wi-Fi for wireless communication. Weather radars emit pulses of energy to detect precipitation, listen for the reflection of these pulses, and use the timing of the reflections to create a 3D representation of atmospheric precipitation. These systems are widespread, not limited to airports, and have a significant range of operations.

The use of the 5GHz spectrum by radar systems is why Dynamic Frequency Selection (DFS) is crucial in Wi-Fi networking to avoid interference with these essential services.
