Hi Mustafa,
You can use a 20dbi or 30dbi module, and the second one can raise 8Km. If you need more, you can use E22 or E220 to raise 11km, but I think you need a good antenna and a 5v power supply with more powerful modules.
If you get an E22 or E220, you can check RSSI to have data to elaborate.
In this topic, I do a simple comparison table on this topic.
E32 x E22 x E220
