Rasberry Pi signal repeater/extender

I’m trying to extend the range of a robot that uses UHF or Wi-Fi signal to communicate with its controller with a range of 100 meters.

Is it possible to implement RPi 4 to serve as a signal booster/extender to increase the range?

  • Any thoughts I can start with to build my projects would be highly appreciated.
  • Doesn’t have to be a Pi 4 if there is a better alternative.

I’m still new to the RPi thing and I’m hoping to learn more from this project.

Yes, there is a better alternative which has nothing to do with the Pi. Get an RC radio (the one they use to control model cars / boats / aircrafts). Those usually come in form of handheld controllers with sticks and buttons in addition to the transmitter, but there are bare RC transmitters which can be fed values to be transmitted via UART or a similar interface.
