Does a mobile phone signal blocker affect the Internet access of a laptop computer? from dojammer's blog

Because of its portability and other advantages, more and more people use laptop computers for office work and even for entertainment. In some occasions, cell phone signal blockers may be used to block and interfere with mobile phone signals due to special needs such as confidentiality. As a user of a laptop computer, you will definitely have similar questions such as whether a mobile phone signal blocker affects the Internet access of a laptop computer.

To understand the answer to the question of whether a mobile phone signal blocker affects the Internet access of a laptop computer, you must first understand the interference frequency band of the mobile phone signal blocker and the frequency band used by the laptop computer to surf the Internet. If the interference frequency band of the mobile phone signal blocker overlaps with the frequency band used by the laptop computer to surf the Internet, it will affect the Internet access function of the laptop computer.

First look at the interference frequency band of the mobile phone signal blocker.

Because domestic operators have a wide signal coverage and use many standards, mobile phone signal blockers generally interfere with 2G, 3G, and 4G frequency bands to achieve the effect of full network shielding. In addition, mobile phone signal blockers produced by Fujian Lingxin Information Technology Co., Ltd. will also interfere with and block WLAN signals, which is what we often call WiFi signals. WiFi can also be divided into WiFi2.4 band and WiFi5.8 band according to the frequency band.

After understanding the interference frequency band of the mobile phone signal jammer, let's take a look at the frequency band used by laptops to surf the Internet.

Laptops generally have two ways to surf the Internet, one is wired Internet access, that is, Ethernet port Internet access, and the other is wireless Internet access. Referring to the description of "Does the mobile phone signal jammer affect wired Internet access", it can be known that the mobile phone signal jammer cannot block or interfere with wired Internet access, so here we mainly summarize the frequency band of wireless Internet access for laptops.

According to the classification of laptops currently on the market, wireless Internet access supports single-frequency and dual-frequency. The so-called single-frequency refers to only supporting WiFi2.4 frequency band to connect to the Internet, while dual-frequency means supporting WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-frequency, and some high-priced or more conscientious ones will be equipped with dual-frequency Internet access.

After understanding the working frequency bands of mobile phone signal jammers and laptops, sharp-eyed people may understand it at once. In short, mobile phone signal jammers may affect laptop Internet access. It is divided into the following situations:

1. The mobile phone signal blocker does not have a WLAN module, which does not affect the Internet access of laptops;

2. The mobile phone signal blocker supports the WiFi2.4 frequency band, which affects the Internet access of single-frequency laptops, but does not affect the Internet access of dual-frequency laptops;

3. The mobile phone signal blocker supports the WiFi2.4 and WiFi5.8 frequency bands, which will affect the Internet access function of laptops. #wireless jammer

Through the above detailed understanding, the answer to whether the mobile phone signal blocker has an impact on the Internet access of laptops is also available. The mobile phone signal blocker may affect the Internet access function of laptops. For those customers who need to use mobile phone signal blockers for shielding, it is obviously reasonable to equip those laptops that must be connected to the external network for work with Ethernet cables, so that the effect of having both fish and bear's paw can be achieved.
