i hope can get a 4g signal jammer circuit

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 cell phone 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.Most of the laptops only support single frequency, and some high-priced or more conscientious configurations will be equipped with dual-band Internet access.

With technological innovations, cell phone jammer is constantly being upgraded, roughly divided into new 4G Signal Jammer Circuit and traditional jammers. Compared with traditional jammers, the advantages of digital jammers are very obvious. In terms of power, traditional jammers are high-power jammers, so the relative radiation will be slightly higher. Digital jammers have very small radiation; and the shielding effect is very good at low power.In terms of the impact on the base station, the traditional digital jammer will slightly affect the base station while shielding; the relative digital jammer has no effect on the base station and can achieve a perfect shielding effect.

In the shielding system, the traditional shielding device can achieve full-standard shielding, but when a new standard comes out, the traditional shielding device cannot shield the new standard, but the digital shielding device supports the long-term evolution of the signal and is adaptive When a new standard appears, it will automatically shield the newly added jammer signal without adding new hardware modules.In terms of the number of use, traditional jammers with detection linkage may be used in a very large number, and the amount of equipment required for digital jammers is significantly less.
