As described in Wikipedia, FPV (First Person View) is also known as RPV (Remote Person View) or video pilot. This is a method of controlling an RC vehicle from the perspective of a driver or pilot. The sudden increase in the use of drones or unmanned aerial vehicles in recent years has also increased the use of FPVs, which are most commonly used to control these objects.
The “signal jammer or UAV” is either controlled or controlled by a remote control seen from the first person perspective, which is transmitted to the pilot’s glasses or monitor via wireless technology. More complex versions of drones include a pan and tilt camera that is controlled by a gyroscope sensor in the pilot’s glasses and is equipped with two integrated cameras that enable a 3D view.
Let’s take a look at the basics of radio frequencies:
2.4 GHz and 5.8 GHz are two of the most common frequencies when working with FPV quadcopter drones.
2.4 GHz is the usual high frequency with which quadcopters connect the ground transmitter to the drone. If you are familiar with frequencies, you may already know that 2.4 GHz is the same frequency that wireless computer networks work with. So there may be several incidents where loss of control over flying objects in densely populated residential areas has been reported where there are too many radio signals.
Another problem associated with quadcopters is that they interfere with their on-board systems. This is mainly due to the involvement of two transmitters – one to transmit the pilot signals to the vehicle and the other to transmit the video signals back to the pilot.
5.8 GHz is another radio frequency used in quadcopter technology to avoid entangling frequencies in the same band. This frequency is often used in DJI Phantom models. Let’s look at how the DJI Phantom Quadcopters avoid the most common problems when dealing with radio frequencies.
Phantom 1 – This UAV works at 2.4 GHz. If you want to add an FPV, you have to do it yourself and use the 5.8 GHz frequency to avoid common problems.
If you want to use a GoPro or other action camera with its unique wireless system, you need to disable the wireless option. Otherwise the aircraft will be disturbed. Phantom FC40 – This drone uses the 5.8 GHz radio to fly as it has a separate 3.4 GHz system to transmit videos and photos to the pilot.
Phantom 2 – This drone uses the 2.4 GHz RF for the control unit. Therefore, you need to use additional kits that use a frequency of 5.8 GHz for the transmission of FPV signals.
Phantom 2 Vision and Vision + – Both drones use 5.8 GHz for control and 2.4 GHz for FPV, smartphone app connection and telemetry.
Final judgment
So if you buy a phantom drone or other drone without a camera, you will need to use an FPV device with a frequency of 5.8 GHz and vice versa to get a smooth experience. It is worth noting that both RF signals are considered LOS or line-of-sight signals, which means that they will not work if there is a barrier between the drone and your remote control. It is best to fly a drone in places where you can see it with the naked eye. Otherwise, you could damage your drone or lose it entirely.
