Laptops are used by more and more people for office work and even entertainment due to their advantages of portability. In some occasions, due to special needs such as confidentiality, full-band signal jammers will be used to shield mobile phone signals. interference. As a person who uses a notebook computer, there must be doubts about whether the full-band signal jammer will affect the Internet access of the notebook computer.
If you want to know the answer to the question of whether the full-band cell phone blocker affects the Internet access of the notebook computer, you must first understand the interference frequency band of the full-band signal jammer and the frequency band used by the notebook computer to access the Internet.
First of all, if the interference frequency band of the full-band signal jammer coincides with the frequency band used by the notebook computer to access the Internet, it will affect the Internet access function of the notebook computer. Let's take a look at the interference frequency band of the full-band signal jammer. Because the signal coverage of domestic operators is wide and there are many standards in use, the full-band signal jammer must achieve the effect of shielding the entire network. Generally, it will effectively shield interference for 2G, 3G, 4G, 5G frequency band signals, WiFi, GPS, and Bluetooth signals.
After understanding which frequency bands the full-band signal jammer introduced above can interfere with, let's 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, Internet access through the Ethernet port, and the other is wireless Internet access. At present, the full-band signal jammer cannot shield or interfere with wired Internet access, so here we mainly describe the frequency band of wireless Internet access for laptop computers. According to the classification of notebook computers currently on the market, wireless Internet access supports single-band and dual-band. The so-called single frequency refers to only supporting the WiFi2.4 frequency band to connect to the Internet, while the dual frequency refers to supporting the two frequency bands of WiFi2.4 and WiFi5.8 to connect to the Internet. Most laptops only support single-band, and some with high prices or more conscientious configurations will be equipped with dual-band Internet access.
After understanding the respective working frequency bands of the full-band signal jammer and the notebook computer, sharp-eyed people may immediately understand whether the full-band signal jammer will affect the laptop's Internet access. To put it simply, the full-band signal jammer may affect the Internet access of the laptop.
Specifically, it needs to be subdivided into the following situations:
1. The full-band signal jammer does not have a WLAN module, which does not affect the wireless Internet access of the laptop;
2. The full-band signal jammer supports WiFi2.4 frequency band, which affects the wireless Internet access of single-frequency notebook computers, but does not affect the wireless Internet access of dual-frequency notebook computers;
3. The full-band signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet access function of the laptop.
