Knowledge of drone and 4G phone jammer week frequency

By Wikipedia’s explanation, FPV (first person view) is called RPV (remote person angle) or video navigation. It is a backpass facility with a built-in wireless camera based on a remote-controlled model airplane or car model, which is a new way of playing the model on the ground while watching the screen. Over the last few years, more and more drones have been used. This type of FPV utilization is most often seen.
The drone is actually a pilot’s eyepiece surveillance, a higher version of the drone incorporates two in-vehicle cameras and a portable jammer 4g in the pilot’s eyepiece. Can be 3D view

Wi-Fi Radio Blocker Let’s learn basic knowledge about week frequency

2.4GHz and 5.8GHz are the two most common frequencies for being connected to terrestrial radio transmitters and UAVs
The 2.4 GHz band is a common radio frequency. Often used to connect to ground-based transmitter axis aircraft and UAVs. If you know more about frequencies, you may know that the 2.4GHz band of unwanted cell phone jammers is also used in wireless computer networks. Therefore, it can be expected that there will be many accidents that lost control of the aircraft in densely populated residential areas with too many radio signals.

Another problem with drones is that they interfere with the vehicle’s navigation system. This is mainly due to the fact that the two transmitters worked together, one transmitting the guided wave number signal to the vehicle and the other transmitting the video signal to the driver.

The 5.8GHz band is used in 4-axis aircraft technology to avoid entanglement of the same frequency band with other RFs. This week frequency is found in the Dow Phantom model. Let’s see how UAVs work around wireless frequency issues

Phantom 1 This drone works in the 2.4GHz band. If you plan to participate in FPV, you will have to do it yourself using the 5.8 GHz frequency of the mobile deterrent jammer to avoid common problems.

If you use GOPRO or any other action camera’s unique wireless system, remember that the wireless option is turned off. Otherwise, it can interfere with the aircraft. The Phantom FC40 drone has adopted a radio frequency of 5.8 GHz. And since it has a single 3.4GHz system, you can send videos and photos to your pilot.

Phantom 2 Because this drone uses control at a 2.4 GHz radio frequency of a radio signal jammer, you have to use additional tools. Therefore, it transmits the FPV signal using the frequency of 5.8 GHz.

Phantom 2 Vision and Vision+ These two types of drones use 5.8 GHz and 2.4 GHz FPVs separately to take advantage of smartphone application connectivity and telemetry.

Portable jammer final conclusion
Therefore, if you bought a phantom UAV without a camera and other drones, you should use the 5.8 GHz frequency and FPV. By the way, it is worth noting that the RF signal is said to be a LOS mobile jammer or visual signal line. If there is no barrier between the UAV and the remote control, it will show that they cannot work. The best flying area of ​​the drone is directly visible to the naked eye. Otherwise, your drones could be damaged or lost.

Communication function suppression device. Development background and utilization of mobile phone suppression device

While convenience has improved due to the rapid spread of communication devices such as mobile phones and PHS, ringing tones of communication devices and noise caused by telephone calls have become a social problem in spaces such as theaters and halls where a quiet atmosphere is required. I will. In one hall, concerts by prominent conductors have even been interrupted. For this reason, the current situation is that operators such as theaters are strongly demanding the development of effective countermeasure technology.

To prevent ringing tones and calls from mobile phones, PHS, etc.
For this reason, there is a movement to prevent annoyance due to ringing sounds, etc. by using wireless equipment (mobile phone suppression device) that has the function of suppressing ringing sounds and calls from mobile phones.
