Does the cell phone signal blocker affect the Internet access of the laptop?

Laptops are used by more and more people for office and even entertainment due to the advantages of being portable . As a person who uses a laptop computer, there must be similar questions such as whether the mobile phone signal jammer will affect the Internet access of the laptop computer.

In order to understand the answer to the question of whether the mobile phone signal jammer affects the Internet access of the laptop, we must first understand the interference frequency band of the mobile phone signal jammer and the frequency band used by the laptop to surf the Internet. If the interference frequency band of the mobile phone signal jammer coincides with the frequency band used by the laptop to access the Internet, it will affect the Internet access function of the laptop.

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

Because domestic operators have a wide range of signal coverage and use many systems, mobile phone signal jammers generally interfere with 2G, 3G, and 4G frequency bands in order to achieve the effect of shielding the entire network. In addition, the cell phone signal blocker will also block the interference of the WLAN signal, which is often referred to as the WiFi signal. WiFi can also be subdivided into WiFi2.4 band and WiFi5.8 band by frequency band.

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

Laptops generally have two ways to access 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 "Do mobile phone signal jammers affect wired Internet access?", we can know that mobile phone signal jammers cannot block or interfere with wired Internet access. Therefore, the frequency bands for wireless Internet access of laptops are mainly described here.

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 support WiFi2.4 frequency band to connect to the Internet, and dual frequency means to support WiFi2.4 and WiFi5.8 two frequency bands to connect to the Internet. Most of the laptops only support single frequency, some high price, or more conscientious configuration will be equipped with dual frequency Internet access.

After understanding the respective working frequency bands of cell phone jammers and laptops, sharp-eyed people may understand it all at once. To put it simply, cell phone blocker may affect the Internet access of laptops. It is subdivided into the following situations:

1. The mobile phone signal jammer has no WLAN module, which does not affect the Internet access of the laptop;

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

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

Through the above detailed understanding, there is also an answer to whether the mobile phone signal blocker affects the Internet access of the notebook computer. The mobile phone signal blocker may affect the Internet access function of the notebook computer. For those customers who need to use a mobile phone signal jammer for shielding, it is obviously reasonable to equip laptops with Ethernet cables that must be connected to the external network for office work, which can achieve the effect of having the best of both worlds.
