SUMMARY

4G LTE is not inherently compatible with Low Earth Orbit (LEO) satellites due to the unique design requirements of satellite mobile systems. The vast coverage area and shared spectrum resources necessitate a different approach compared to terrestrial systems. Additionally, the backhaul challenges presented by LEO satellites, which are not geosynchronous, complicate the implementation of 4G LTE. While 3GPP has established standards for satellite communication within UMTS, specific standards for 4G LTE in satellite applications are not yet defined.

A satellite mobile system needs to be designed differently to a terrestrial one, because the coverage of the satellite is so huge and the spectrum resource is shared between so many users. In addition, the backhaul from the satellite for a Leo is a significant problem because it is not geosynchronous. Terrestrial mobile traffic is back hauled to the switching centre and a large fixed network, which we would like to avoid with a satellite. For satellite telephony, the two users will often be within the same coverage area, but for broadband this is not the case and traffic has to be back hauled.
 
Are there any special standards designed for satellites? I know 3GPP has a special standard for satellite in UMTS.Senmeis
