Almost 14 Watts oriri.
1W is enough for a 1km distance. But we will make 2W for you to ensure the best reception performance.
It also depends on your local environment, whether it is LOS or NLOS, please check our test video, there are many floors and buildings.
For changing different power amplifiers about 500 MW, 1 watt, 2 watt, ma ọ bụ 10 watts. It is not just adjusting the setting in the software, You also need to change the Power amplifier hardware inside the transmitter. It can not operate and change at the normal end-user, and the cost and transmitter metal box size are different.
