Question

what are the new developments which are improving the communication routes in the region of high altitudes

Answer 1

A communications satellite, sometimes abbreviated to SATCOM, is an artificial satellite stationed in space for the purposes of telecommunications. For fixed or point-to-point services, communications satellites provide a microwave radio relay technology complementary to that of submarine communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting, for which application of other technologies, such as cable, is impractical or impossible. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low Earth orbits.
