Are there any plane accidents due to cell phone signals?
With the increase in the use of mobile phones, reports of aircraft autopilot failures and instrument display failures are not uncommon.So for your own safety, please make sure all our electronic devices are turned off when flying.
The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station so the mobile phone cannot establish a connection with the base station.
A jammer fundamentally doesn't block your phone's electromagnetic signal but instead blocks the channel of your phone's signal.Turns out the jammer GPS themselves would make the situation worse, not help the aircraft electronics.Many users will take the plane to go to faraway places.
When the mobile phone is working, it is within a certain frequency range.A mobile jammer is an electronic device that transmits electromagnetic signals at the same frequencies as mobile and other consumer electronic devices.
Why aren't cell phone jammers installed on planes?
This affects the normal operation of the aircraft.Boeing investigated the incidents and found that signals from cell phones, laptops, etc. were responsible.Although the mobile phone signal jammer is called a "blocker", it is actually a signal "jammer" and a high-power jammer.This can interfere with signals from mobile and other devices.
According to this communication principle, the mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process.The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc.This means that the phone's electromagnetic signals still keep transmitting and interfere with the aircraft's electronics.Otherwise, the normal operation of the plane will be affected.
The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method.As a result, the cell phone cannot communicate with the mobile tower.This kind of interference can interfere with the communication between the aircraft and the ground.It should be noted that this instrument must not be installed on the aircraft.
The jammer gps itself emits a large number of electromagnetic signals, and it also interferes with the electronic equipment of the aircraft.Until the plane lands, the mobile phone cannot generate signals and cannot be turned on.The mobile phone signal jammer can avoid the interference caused by the mobile phone signal, but there is one point.
Therefore, although it is said that in order to prevent the influence of mobile phone signals on the aircraft, mobile phones cannot be used on the aircraft, it should also be noted that mobile phone signal jammers cannot be installed on the aircraft, otherwise it will also play a certain role in interference to the aircraft.
