Trying to make sense of losing the signals on long range flying. The app is connected to the range extender over the 2.4GHz channel. That means that all the telemetry info and messages are provided through this channel. The control signal is sent through the 5.8GHz channel, so if the phantom loses this signal the reporting has to be done from the phantom through the telemetry data on the 2.4 channel because the 5.8 channel does not communicate at all with the app. We have 2 scenarios. Scenario 1: control signal lost first. With this scenario, the message can be relayed back to the pilot through telemetry. But, if the control is lost, doesn't the phantom return home? Which means it will get closer to you so how can you have a situation where you will later get a message of connection broken? In other words: we cannot fly the phantom further than the control signal lost point, so how would we would get a connection broken??? Scenario 2: FPV lost first (phantom connection broken). If we lose telemetry and FPV first then even if we flew the phantom further away, how would it be able to let us know when it reached the point of losing control signal? Wouldn't it just return home without a message being sent? And if it was already returning when the FPV was resumed, wouldn't it just say returning home? Is the telemetry being broadcast separately from the video, so that it may still work at a smaller bandwidth After losing FPV? If yes, is the telemetry signal capable of a longer range than the control signal? Is there a third message if we lose telemetry signal? Also curious as to why dji decided to use two separate channels. This requires more hardware, and more antennas and has more points of failure. The control signal is low bandwidth in the direction from controller to bird. The FPV a and telemetry signals are higher bandwidth but in the other direction. Why not have all signals travel on one wifi network? It is not like the transmitter/receiver can't handle this. You can for example stream a movie to your laptop and at the same time play a multiplayer game, requiring bidirectional communication. Finally, instead of setting a fixed FPV streaming bandwidth, why not have the resolution dynamically adapt to the quality of the signal? Or if dji does not want to have a fancy algorithm, they could have the streaming resolution be a function of the distance. These parameters are always known. Did dji get lazy and chose to use two systems because it was easier to slap a standalone video solution? I would prefer one wifi mimo transceiver; one set of antennas and dynamic signal adaptation.
