There are not a lot of telecom satellites that talk to each other in orbit. 98% of what is out there in geostationary orbit operates as a "bent pipe" angled repeater/amplifier between terminals and large earth stations.
Iridium satellites in LEO use the Ka band to trunk connections with each other. Certain US DoD satellites have geostationary-to-geostationary links in the 30-40 GHz bands. Never heard of 60 GHz being used for satellite to satellite. https://en.wikipedia.org/wiki/Mobile_User_Objective_System https://en.wikipedia.org/wiki/UFO_%28satellite%29 https://en.wikipedia.org/wiki/Wideband_Global_SATCOM The TDRS satellites talk to each other over space-to-space links. https://en.wikipedia.org/wiki/Tracking_and_Data_Relay_Satellite_System It is rumored but not known for certain that various NRO satellites (both imagery and radar) have the capability of talking to each other in orbit for realtime data transfer and observation, such as from LEO observation of a site in China, relayed via space to a ground terminal in Guam, Hawaii or California.
