Does the mobile phone signal jammer affect the Internet access of the laptop?

Laptops are used by more and more people for office and even entertainment purposes due to their convenient portability and other advantages. In some occasions, cell phone jammer may be used for special needs such as confidentiality to shield and interfere with mobile phone signals. As a person who uses a laptop computer, there must be similar questions about whether the mobile phone signal jammer will affect the Internet access of the laptop computer.

 

 

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

First look at the interference frequency band of the cell phone jammer.

Because of the wide signal coverage of domestic operators and the use of multiple standards, mobile phone signal jammers must achieve the effect of shielding the entire network. Generally, they will interfere with the 2G, 3G, and 4G frequency bands. In addition, mobile phone signal jammers such as those produced by Fujian Lingxin Information Technology Co., Ltd. also interfere with WLAN signals, which are commonly referred to as WiFi signals. WiFi can also be subdivided into WiFi2.4 frequency band and WiFi5.8 frequency band according to frequency band.

Understand the interference frequency band of the mobile phone signal jammer, and then look at the frequency band used by laptops to surf the Internet.

Laptops generally have two Internet access methods, one is wired Internet access, that is, Internet access via Ethernet port, and the other is wireless Internet access. Refer 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 shield or interfere with the wired Internet access. Therefore, the frequency band of the laptop wireless Internet access is mainly covered here.

According to the current classification of laptops 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, while 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, and some high-priced or more conscientious configurations will be equipped with dual-band Internet access.

After understanding the respective working frequency bands of mobile phone signal jammers and laptops, sharp-eyed people may immediately understand. Simply put, the mobile phone signal jammer may affect the Internet access of the laptop. Subdivided into the following situations:

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

2. The mobile phone signal jammer supports WiFi 2.4 frequency band, which affects the Internet access of single-band laptops, but does not affect the Internet access of dual-band laptops;

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

Through the above detailed understanding, does the mobile phone signal jammer affect the Internet access of the laptop? There is an answer. The mobile phone signal jammer may affect the Internet access function of the laptop. For those customers who need to use cell phone signal jammers for shielding, it is obviously reasonable to equip laptops that must be connected to the external network with an Ethernet cable, so that it can achieve the effect of having both fish and bear's paws.
