Hello I’m working in a project that consists of an autonomous robot and it needs to communicate with a base station and in this way the base station has a GSM module to send data to a website. My problem is the transmission of data between the robot and the base station, which in this case will be radio frequency, and I am looking for a hardware that allows me to send data from the robot to the base station, such as video frames and sensory data. In this way the base station must also send data to the robot, so bidirectional communication is required. The distance is about 5/6km and we are currently considering line of sight, that is, very few obstacles. Can anyone help me with the hardware for radio frequency communication?
