wifi jammer shields other people’s wifi signals

The family asked a question: Which phones support dual WiFi, how? I was confused at first, and I don't know what these two WiFi phones are? Then I think about it, is dual WiFi only dual band? Dual WiFi phones refer to dual-band phones. Not to mention, this is the first time I have heard of this pair of WiFi phones. Next, take a look at this dual WiFi (that is, dual band). Before we start, we still changed the dual WiFi to dual band according to the standard name.

The dual frequency of the mobile phone refers to the two working modes of the mobile phone supporting wireless signals, and can also be understood as the two WiFi connection modes of the mobile phone. One of the frequencies is working in the 2.4GHz frequency band, and the other is working in the 5GHz frequency band, sometimes referred to as 2.4G and 5G. One thing to note here is that the 5GHz here is not the same thing as the 5G of the base station. Don't make a mistake, or you will be embarrassed.

Since there are two ways of working, we need to compare, which is better, 2.4G or 5G? In terms of technological development time, 5G appeared later than 2.4G. Based on the judgment that the new technology is better than the old technology, it is concluded that 5G is better than 2.4G. In terms of data transmission speed, the transmission speed of 5G is 5 times that of 2.4G. It can be seen from this multiple gap alone that 5G will have a better WiFi experience. In order not to affect the 5g experience speed, we can use a wifi jammer to prevent others from occupying the network signal.

Dual-band mobile phones can connect to 2.4G WiFi signals as well as 5G WiFi signals. Mobile phones that do not support dual-band can only connect to 2.4G WiFi signals. Is this clear? Next, let's take a look at how to achieve a dual-band environment.

To achieve a dual-band environment, two conditions must be met: First, you must have a mobile phone that supports dual-band. Second, you have to have a wireless router that supports dual-band. Of course, if your neighbor next door has a dual-frequency signal for you to use. The next thing is simple, find the name of the WiFi you want to connect to, and enter the WiFi password to connect.

When you turn on the phone, you can't find the 5G WiFi signal. Then we have to check the wireless router at home. It is very likely that the router at home is not a dual-band router and cannot provide 5G WiFi signals. At this point, you have to change the router to a dual-band, let a professional help you set it up, and you can connect to 5G WiFi. Seeing this, do you understand the purpose of mobile phone stores to promote dual-band mobile phones for you? Maybe, I will also sell you an extra dual-band router by the way, and sell it properly.

It should be noted here that you can only choose one connection for 2.4G and 5G, and you cannot connect two at the same time. Speaking of this, you must have another question. Two signals can only be connected to one. Then how should 2.4G and 5G be selected? Don't worry, then look down. Dual-frequency usage skills, 2.4G and 5G are different frequencies, each with different advantages. This advantage depends on the network layout, and different methods will be used according to the signal coverage and whether there are too many obstacles (walls, etc.).

In reality, 2.4G's wall-around effect is better than 5G, and 5G's anti-interference ability is better than 2.4G. Therefore, in use, we generally use our strengths and avoid our weaknesses. When you are in a room with many partitions, it is recommended to connect to a 2.4G WiFi signal. When there is no wall in the living room, connect 5GWiFi signal. In this way, a relatively stable network experience can be obtained.

If you live in a high-rise community, the neighbors on the top, bottom, left, and right have WiFi signals. When you use 2.4G WiFi signal, it will easily overlap with neighbor's channels, which will easily cause network traffic jam. Because 2.4G has only 3 channels that do not interfere with each other, and 5G has 22 independent channels. When you turn on the WiFi of your mobile phone, you find that there are densely packed signal names. At this time, if you use 5G WiFi to connect to the Internet, it will be less susceptible to interference and the network speed will be more stable.

With more and more smart home appliances at home, many home appliances must be connected to the Internet. At present, most of the home appliances on the market do not support dual frequency, they are all connected through 2.4G WiFi. In this case, if you want to get a good network experience, it is also recommended that you use 5GWiFi to connect to the Internet, but if you are not assured that your home’s wifi is connected by others, you can use a WiFi jammer to block it, which can also ensure the normal operation of the network .
