Interference of 4G frequencies with c band communication satellites.

By introduction of 4G Transmission in Bangladesh, It is found that, c-band satellite  communication is in problem.

The 4G transmission are at 1700 and 2100 Mhz...

A filter may solve the problem, but it will cause loss of 3 to 6 db signal.

What are other possible solutions ?

It can be noted that, different satellite receivers  behave in a different way. One receiver has no  problem on a specific channel, but other one does not work on that Transponder.
Looking for your valuable comments please and your experience if any ?
