60 ghz is attractive for secure satellite crosslinks because it allows for high data rates narrow beams and lying in a strong absorption band of oxygen provides protection.
V band satellite communication.
The x band is used mainly for military communications and wideband global satcom wgs systems.
Rf components in the q v band.
Uplink 7 9 8 4 ghz.
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.
Milstar 1 and milstar 2 military satellites.
Used for satellite communications.
With relatively few satellites in orbit in this band there is a wider separation between adjacent satellites making it ideal for comms on the move cotm applications.
In europe ku band downlink is used from 10 7 ghz to 12 75 ghz for direct broadcast satellite services such as astra.
However for broadband communications provider advantech wireless the move to q v band is only marginally on the radar.
Downlink 7 25 7 75 ghz.
15 1995 the v band at 60 ghz was used by the world s first crosslink communication between satellites in a constellation.
Satellite operator interest in new bands must be expected as they must look so far ahead.
This communication was between the u s.
The satellite business for operators especially is a long term one and so future requirements need to be addressed far in advance.
This news is significant because new tools for testing rf components in the q v band will help ensure the quality of new high throughput satellite payloads.
