Computer control through the wall?

Question

Wireless technologies

In a new apartment (odnushka) I want to make myself a workplace on the balcony (balcony in the kitchen), I plan to hang a TV in the room, I want to be able to display the image on the TV and control the PC. While only a wireless keyboard and mouse comes to mind, the distance between the transmitter and the keyboard is about 5 meters, but there will be a wall in the signal path. Perhaps there are other options?

Answer 2

The wireless receiver can be placed on a USB extension cable (possibly active) closer to the room.
Moreover, you somehow lead the wire to the TV, you can also stretch the extension cord there.
