Q: My question is that when 1 module is transmit datato a receiver 1 km away, does it have a negative effect on the 5 modules next to it? . Will there be problems(burn) in other next to 5 modules?
A: If conditions permit, don't place it so close.
If there is no other way, just place it like this.
You can use it at a lower power level. EBYTE's products are sturdy and won't burn out that easily.
