  2. X Band Satellite Communication - Wikipedia

    en.wikipedia.org/wiki/X_Band_Satellite_Communication

    x Band Satellite Communication operates in the part of the X band or Super High Frequency (SHF) spectrum which is designated by the International Telecommunication Union (ITU) for satellite communication, which is those frequencies in the range 7.25 GHz to 7.75 GHz (Space to Earth) and 7.9 GHz to 8.4 GHz (Earth to Space).

    en.wikipedia.org/wiki/GPS_signals

    The signal is broadcast in a frequency band protected by the ITU for aeronautical radionavigation services. It was first demonstrated from satellite USA-203 (Block IIR-M), and is available on all satellites from GPS IIF and GPS III. L5 signals have been broadcast beginning in April 2014 on satellites that support it. [1]

  6. C band (IEEE) - Wikipedia

    en.wikipedia.org/wiki/C_band_(IEEE)

    Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks. Note that by using the band from 3.7 to 4.0 GHz, this C band overlaps somewhat with the IEEE S band for radars.

  7. S band - Wikipedia

    The Eutelsat W2A satellite was launched in April 2009 and is located at 10° East. In Indonesia, S band is used by MNC Vision for Direct-to-Home satellite television (unlike similar services in most countries, which use K u band). The frequency typically allocated for this service is 2.5 to 2.7 GHz (LOF 1.570 GHz).

  8. Satellite Internet access - Wikipedia

    en.wikipedia.org/wiki/Satellite_Internet_access

    The effects are less pronounced on the lower frequency 'L' and 'C' bands but can become quite severe on the higher frequency 'Ku' and 'Ka' band. For satellite Internet services in tropical areas with heavy rain, use of the C band (4/6 GHz) with a circular polarisation satellite is popular. [46]

  9. L band - Wikipedia

    en.wikipedia.org/wiki/L_band

    Iridium Communications satellite phones use frequencies between 1616 and 1626.5 MHz [4] to communicate with the satellites. Iridium Communications 2-way messaging service Snapdragon Satellite will utilize frequencies in the L Band as well. Inmarsat and Ligado Networks (formerly LightSquared) terminals use frequencies between 1525 and 1646.5 MHz.
