Satellite uplink frequency bands. L band in the range from 1621 35 to 1626 5 mhz used for both uplink and downlink. The c band frequencies of 5 4 ghz band 5 15 to 5 35 ghz 5 47 to 5 725 ghz or 5 725 to 5 875 ghz depending on the region of the world are used for ieee 802 11a wi fi wireless computer networks. Iridium satellite frequency description. The c band alliance was an industry consortium of four large communications satellite operators in 2018 2020.

70 150 mhz. Satellite vsat communication is split up in to four radio frequency rf bands that commercial communication and military satellites operate within. System activation was first observed at 01 02 utc on september 2. Io 86 lapan a2 145 880 mhz.

Satellite frequencies ghz band. With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily.

The most popular frequency bands available on satellite are l band s band c band x band ku band k band and ka bands. The higher frequency bands typically give access to wider bandwidths but are also more susceptible to signal degradation due to rain fade the absorption of radio signals by atmospheric rain snow or ice. Uplink satellite dishes are very large often as much as 9 to 12 metres 30 to 40 feet in diameter 23 to achieve accurate aiming and increased signal strength at the satellite. For real time updates about which mode the satellite is in see the amsat live oscar satellite status page.
