If it is just text characters then my suggestion would be to look at using ANT radio transceiver module or new Bluetooth 5 transceiver module.

A few questions to narrow it down a bit.

Will the controllers be indoors or outdoors?

How often will the controllers need to communicate with each other. i.e. continuous streaming or intermittent?

Then how much data will be sent per transmission.
