Baris 15:
Saat ini pita frekuensi K<sub>a</sub> diaplikasikan untuk telekomunikasi satelit, antara lain untuk keperluan [[internet]], ''video conference, video telephone, data broadcasting, voice (telepon) rural/remote area, tele-medecine, tele-education,'' SCADA, ''local television (broadcasting) satellite data relay services,'' ''Inter Satellite Links (ISL)'', ''news gathering'' dan ''PC Networks''.<ref name="ReferenceA"/>
Namun demikian sebagian besar aplikasi yang akan dilayani oleh pita frekuensi Ka adalah aplikasi Internet dan [[Multimedia]].
