Hello,

I'm looking for long distance about (5-10 km) audio voice transmitter and receiver.

I'd seen few chip from TI and NXP Sub GHz but i'm unaware of that whether it is suitable for audio or not

can someone plz suggest any ready device and any chip for development
 

You need short wave radio for low power long haul audio .. otherwise we would need so many cell towers at 5Ghz every few blocks or 1 to 0.5 km depending on tower size and terrain.

Look up Friis loss calculator
 

Does DRA818U work for me?

In many review i found that it will cover 3-5 Km line of sight?
 

I can hear the ISS on a walkie talkie when it passes overhead, that's about 405Km distance. Line of sight makes it easy so beware of claims of long range. You might cover 3-5Km line of sight but not be heard in the next room.

Brian.
