Kurtz-Under Band (Ku-Band)

The Ku band is directly under the K band, which is used for other types of radar and satellite communications that generally run above the former; for example, the NATO K band used by the International Telecommunication Union (ITU) runs above 20 GHz, whereas the IEEE K band runs from around 18 GHz.

The Kurtz-under band is administered in segments, according to the ITU. It generally provides for the range of voice and data services offered to consumers over common satellite systems and, as a result, is a major factor in spectrum-use issues arising from the emergence of new satellite services users. Law enforcement may also use parts of this range for radar detection.
