New Communications satellite on the earth synchronous orbit

Most of new communications satellites,will have many big capacity Ku band and Ka band transponders,
In one satellite, the downstream Ku band frequency will cover from 10GHz to 12.75GHz (Ku band have 2.75GHz bandwidth),
and the downstream Ka band frequency may cover from 26.5Ghz to 29GHz (Some of under 29GHz,so the satellite's Ka band transponders bandwidth less than 2.5GHz.).
Some of new communications satellites have some large power S band transponders,for DVB-SH broadcasting.Any S band transponders use Ku band for upstream.
Many of new communications satellites,will not have C band transponders.But still a few of new satellites,most of for less developed countries,still have C band transponders. For example, Chinese satellites will still have C band transponders,but many Chinese satellites not have Ku band transponders,some of have a few of Ku band transponders.

International Telecommunication Union will implement new policy, each 2 longitudes have one communications satellite's location. And will order, if a new communications satellite's Ku band frequency will coincide with one old communications satellite's Ku band frequency, when make the communications satellite,the new satellite's Ku band frequency must yield the nearby old old communications satellite's Ku band frequency.(So these kind of new satellite not have 2.75GHz bandwidth on Ku band.)
