Ku Band Satellite. The term "Ku band" refers to the 12 to 18 gigahertz ("GHz") portion of the microwave section of the electromagnetic spectrum, which is used for satellite transmissions. One advantage of using the Ku band is that it is technically faster than an ATG transmission for the purpose of inflight Wi-Fi (around 50 MB/s). The Ku band is mainly used for satellite communications, especially downlink, used by direct-transmission satellites for satellite television and specific applications such as the NASA's Tracking Data Relay Satellite used for both the space shuttle and for communications from the International Space Station (ISS).
