Does a mobile phone signal jammer affect laptop wireless Internet access?
If you want to understand the answer to the question of whether a signal jammer for cell phone has an impact on laptop Internet access, you must first understand the interference frequency band of the mobile phone signal jammer and the frequency band used by laptop computers to access the Internet.
First of all, if the interference frequency band of the mobile phone signal jammer overlaps with the frequency band used by the laptop to access the Internet, it will affect the laptop's Internet access function. Let’s first take a look at the interference frequency band of mobile phone signal jammers. Due to the wide signal coverage of domestic operators and the wide range of application standards, mobile phone signal jammers must achieve the effect of blocking the entire network. Generally, they will effectively block interference for 2G, 3G, 4G band signals, WiFi, GPS, and Bluetooth signals.
After understanding which frequency bands the mobile phone signal jammer introduced above can interfere with, let’s take a look at the frequency bands used by laptops to access the Internet.
Laptops generally have two ways to access the Internet, one is wired Internet access, that is, Ethernet network port Internet access, and the other is wireless Internet access. At present, signal blockers cannot block or interfere with wired Internet access, so here we mainly describe the frequency bands for laptop wireless Internet access. According to the current classification of laptops on the market, wireless Internet access supports single-band and dual-band. The so-called single-band means that it only supports the WiFi2.4 frequency band to connect to the Internet, while the dual-band supports the WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-band, and some that are more expensive or have more conscientious configurations will be equipped with dual-band Internet access.
After understanding the respective working frequency bands of mobile phone signal jammers and laptop computers, sharp-eyed people may immediately understand the issue of whether mobile phone signal jammers have an impact on laptop Internet access. Simply put, mobile phone signal jammers may affect laptop Internet access.
Detailed requirements are broken down into the following situations:
1. The mobile phone signal jammer does not have a WLAN module and will not affect the wireless Internet access of laptops;
2. The mobile phone signal jammer supports the WiFi2.4 frequency band, which affects the wireless Internet access of single-band laptops but does not affect the wireless Internet access of dual-band laptops;
3. The mobile phone signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet function of the laptop.
Through the above detailed understanding, we have the answer to whether the mobile phone signal jammer will affect the laptop's Internet access. The mobile phone signal jammer may affect the laptop's wireless Internet access. For those customers who need to use mobile phone signal jammers for shielding, they need to equip laptops with Ethernet cables for connecting to external network offices, so as to achieve the best of both worlds.
