Now schools required to design a lesson about one kilometer within the scope of the wireless communication control device, could you tell me what are the communication way? Single-chip microcomputer control are available, and better penetrability, knowledge is limited, please give directions,

On STM32F103 + hour LORA atom, a serial port to send and receive, is easier to achieve
The theory of 3 kilometers

refer to 1st floor to the scarecrow to reply:

STM32F103 + the punctual LORA atom, a serial port to send and receive, is easier to achieve
Theory of 3 km distance

Thank you for your comment I went to look at first

Thank you for your reply in understanding

CodePudding user response:

Want to add that the complete control can model points to more, can send data to each other, and separated by walls there will be two to three layers, and control end fitting on the first floor, the receiver in four to five floor, most
