What should I do if my child is addicted to mobile phone chat, what should I do if my child does not have a good rest and plays mobile games late at night, what if my child holds the mobile phone all day and is indifferent to other things? I hope to buy a home cell phone signal jammer to block cell phone signals.
Then let’s talk about how to choose a home cell phone signal jammer
1. Shielding scale: The shielding scale of household mobile phone signal jammers is proportional to the power. For low-power signal jammer, one set in a room is enough, and the shielding scale is about 20 square meters; while for high power jammer, the shielding interval can be Reach 100-400 square meters, depending on the local field strength or whether you need to go through the wall to decide (some parents will choose to install the mobile phone signal jammer in their own room).
2. Signal strength: There are signal base stations or signal amplifiers on the roofs of many residential areas as well as the distance between the signal base stations around the home cell phone signal jammer. Our professional sales staff will teach you how to confirm the signal strength in the room and choose a suitable home jammer.
3. According to the shielded frequency band: Before buying a home mobile phone signal jammer, you need to know which signals you want to shield. The general mobile phone signal (2345G) can be selectively shielded. If you only shield 2G or only 345G, this can be There are 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands adjusted before leaving the factory. Here we need to explain the function of each signal frequency band. In short, 2G is the frequency band for making phone calls, and 2345G is the frequency band for mobile phones to surf the Internet, so it depends on the specific requirements for shielding the frequency band.
4. Appearance: On the outside, the shield can be divided into external antenna and internal antenna. Generally speaking, because the antenna is external, the external antenna stretches out, so it occupies a larger space than the built-in antenna. One point; because of the extended antenna, the effect of the external antenna is more stable.
5. Power supply: The power supply method of household mobile phone signal jammer generally has the built-in lithium battery in the hand, and the power adapter can be used to charge after the electricity is used up; the desktop test room uses 220V voltage power supply, and the car is generally used in the car. It is powered by 12-36V voltage.
