To understand the answer to the question of whether the mobile phone signal jammer affects the Internet access of the notebook computer, you 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.
First of all, if the interference frequency band of the cell phone jammer overlaps with the frequency band used by the notebook computer to surf the Internet, it will affect the Internet function of the notebook computer. Let's first look at the interference frequency band of the mobile phone signal jammer. Because of the wide coverage of domestic operators and the use of multiple standards, mobile phone signal jammers must achieve the effect of shielding the entire network. Generally, 2G, 3G, 4G frequency band signals, WiFi, GPS, and Bluetooth signals are effectively shielded.
Understand which frequency bands the mobile phone signal jammer described above can interfere with, and then look at which frequency bands the laptop uses to surf the Internet.
Laptops generally have two ways to access the Internet, one is wired Internet, that is, the Ethernet network port Internet, and the other is wireless Internet. At present, mobile phone signal jammers cannot shield or interfere with wired Internet access, so the frequency band of laptop wireless Internet access is mainly described 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 supporting WiFi2.4 frequency band to connect to the Internet, while dual frequency means supporting 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 the mobile phone signal jammer and the notebook computer, the question of whether the mobile phone signal jammer will affect the Internet access of the notebook computer may be immediately clear to the sharp-eyed person. To put it simply, the mobile phone signal jammer is likely to affect the Internet access of the laptop.
It needs to be broken down into the following situations:
1. The mobile phone signal jammer does not have a WLAN module, which does not affect the wireless Internet access of the laptop;
2. The mobile phone signal jammer supports WiFi 2.4 frequency band, which affects the wireless Internet access of single-frequency notebook computers, and does not affect the wireless Internet access of dual-frequency notebook computers;
3. The mobile phone signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet function of the laptop.
Does the mobile phone signal jammer affect the wireless Internet access of the laptop?
Through the above detailed understanding, does the mobile phone signal jammer affect the laptop's Internet access? There is an answer. The mobile phone signal jammer may affect the laptop's wireless Internet access function. For those customers who need to use a mobile phone signal jammer for shielding, it is necessary to equip the laptop computer connected to the external network with an Ethernet cable, so that it can achieve the effect of having both.
