Ka-band (Kurtz-above Band)

Frequency range allocated from 17.7GHz on the downlink and to 30.6GHz on the uplink for use by satellite communication systems. Ka-band satellites deliver high-speed broadband Internet connectivity and digital video/audio transmission. Satellites in this frequency range are characterized by two-way or bidirectional communications capability; wider-bandwidth transponders that provide higher overall capacity spot beams that can direct or focus signal transmissions to areas of higher density/population; and more-efficient use of available spectrum through multiple reuse of the same frequency. Ka-band satellites can be implemented as GEO- and non-GEO satellite systems. See also Kurtz-under band (Ku-band), L-band and S-band.
