Hi, I want to build rf communication between my basement and my apartment suite. But i have a lot of problems to solve. In basement there is arduino uno and in my apartment suite , there is pc which records sensor value will be sent from basement. Problems are ;
1)Basement located underground and construction is reinforced concrete blocks.Depth of basement from soil level is about 2 -3 meters( 6-10 feet)
2)After basement there is open air to my apartment suite window and distance is about 30-40 meters(100-130 feet)
So what kind a rf communication i must prefer?
