Transmit Videostream - FPV

[SkyiMotion]

1. Hello everyone,
   We are at the beginning of the development phase for creating FPV-drones.
   I would like to transmit the video signal (FPV) of a camera, e.g. the RPI-22 camera, via radio over a distance of 2 km or more from the STM32MP25x-EV1 evaluation board (STM32MP257F-EV1). The received video signal should be displayed on the screen of a laptop. Unfortunately my research didn't lead to any results. Can you please describe to me which development boards I can use for the following operations:
   Decoding the video signal: STM32MP25x-EV1 Evaluation board (STM32MP257F-EV1)
   Board for the radio transmission of the video signal
   Antenna for transmitting
   Board for receiving the video signal
   Antenna for transmitting
   Decoding the video signal and outputting the video on the laptop
   Thank you for the service.
   Best regards
   Thomas Hollander
