“DJI has a fairly good means to ID an drone in flight. It’s inexpensive and any cellphone has what it takes to receive the information needed from the drone. I would recommend that the channel width is lowered to 5 MHz this would greatly increase the range at the same power levels that are currently being used. For the more it would reduce the amount of interferenceknowing that it is easier to find 5 MHz of spectrum that is not being used 20 or 40 or 80 MHz. All of this can be done with a simple software patch.”
