RE: Ka band & s band
Band Width and their Usage
L-band (1–2 GHz) Global Positioning System (GPS) carriers and also satellite mobile phones, such as Iridium; Inmarsat providing communications at sea, land and air; WorldSpace satellite radio. S-band (2–4 GHz) Weather radar, surface ship radar, and some communications satellites C-band (4–8 GHz) Primarily used for satellite communications, for full-time satellite TV networks or raw satellite feeds. Commonly used in areas that are subject to tropical rainfall, since it is less susceptible to rainfade than Ku band X-band (8–12 GHz) Primarily used by the military. Used in radar applications including continuous-wave, pulsed, single-polarisation, dual- polarisation, synthetic aperture radar and phased arrays. X-band radar frequency sub-bands are used in civil, military and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defence tracking and vehicle speed detection for law enforcement. Ku-band (12–18 GHz) Used for satellite communications. Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Nss6. Ka-band (26–40 GHz) Communications satellites, uplink in either the 27.5 GHz and 31 GHz bands, and high-resolution, close-range targeting radars on military aircraft. |
