You will find that the signal from the phone is unrecognizable, so you will refuse to communicate with the phone. In the early days, What Will Block Radiation From Cell Phones only blocked one set of frequencies, like 2G, while sophisticated jammers can block several types of networks simultaneously, like 2-3-4-5G. So how is this multi-network interference achieved?
Actually simple. That is to say, the interference bands corresponding to these three signals are repeated in a cyclic manner, covering these three interference bands at the same time. The interval of this cycle is so small that the mobile phone has no chance to speak, and can only sit and do it quietly. a brick. Covering 2/3/4/5G, what about bluetooth and wifi? It doesn't matter, it can be done easily.
cell phone jammer Evolved again, adding the frequency bands of bluetooth and wifi to the scanning range, so that several common communication methods in the society are completely covered.
Many people do not understand the difference between Bluetooth, Wi-Fi and mobile data. They seem to be wireless communication technologies. In fact, the main difference between them is the frequency band. In mobile communication technology, 2G mainly works in the 900-1700MHz band, 3G works in the 1900-2100MHz band, 4G works in the 2300-2500MHz band, and 5G works in the 3400-3600MHz band.
Bluetooth and WiFi work at 2.4GHz
In this way, the R&D engineers of Dazhan Electronics can accurately identify the communication frequency band and develop a mobile phone signal blocker with the same frequency band, so as to achieve the purpose of completely blocking mobile phone wireless signals.
During the meeting, the venue will turn on What Will Block Radiation From Cell Phones to block the mobile phone signal. Once you enter the venue, you will be completely "lost", which is very uncomfortable. Some people think that this is a "delayed thing", saying that they have been complained by the masses because the mobile phone cannot be reached.
Some people directly asked: Is it necessary?
Have a meeting and leave the phone temporarily, is it really that serious? At present, the mobile phone has become a "plug-in organ" for modern people, no matter whether it is on the way to work, at work, or at a party, it is a state of "people never leave the machine, and the machine never leaves the hand".
The latest survey shows that Chinese people look at their mobile phones for an average of 3 hours a day, ranking second in the world for their mobile phone addiction. People's attention is severely distracted, and time is cut into fairly fragmented pieces. Not to mention the whole time like a meeting, even if it is ten minutes without looking at the mobile phone, many people are not at ease.
Some netizens described that the most painful thing today is not "the distance between life and death", but "the mobile phone has no power, no network, no signal." In the venue that should be serious and efficient, we are also used to seeing too many "head-down scenery": on the stage to arrange work, he is scanning his mobile phone; on the stage to convey his spirit, he is scanning his mobile phone; on the stage calling for interaction, he is still scanning cell phone.
Are you really so busy that you can't stop for a moment?
Looking closer, there are not many electronic office workers, most of them are browsing the circle of friends, or even visiting online stores and playing games. If you want to portray these people, it is more appropriate to "read only the screen of the mobile phone and ignore the affairs of the meeting". Of course, it is difficult to devote yourself to the agenda of the meeting in such a sloppy and absent-minded state of participation.
These jammers disrupt communication by cycling through interference bands corresponding to various wireless signals, effectively rendering phones unable to transmit or receive data. This technology has become particularly relevant in settings like meetings, where organizers seek to minimize distractions and maintain focus.
This dependence on smartphones has led to concerns about diminished attention spans and fragmented time, impacting productivity and engagement in activities such as meetings.
Critics question the necessity of such extreme measures, arguing that individuals should be able to temporarily disconnect from their phones during meetings. However, the article suggests that for many people, smartphones have become indispensable appendages, accompanying them everywhere and serving as constant sources of distraction.
The pervasive use of smartphones during meetings is portrayed as symptomatic of a broader societal issue, where individuals struggle to detach from their devices and fully engage in present activities.
