For some occasions, the use of mobile phones will bring a lot of troubles, so people will think of installing and using mobile phone signal jammers in places where mobile phones are prohibited, so as to prevent the use of mobile phones and ensure that the mobile phone signals in this area are restricted. Everyone likes to choose some cost-effective products, and mobile phone signal jammers are no exception. They want to spend less money to buy a jammer with a large shielding range, reliable quality, and little interference to the outside world. So let's talk about the cost-effectiveness of jammers.

1. Interference range of jammers

The range referred to here is the effective interference range of mobile phone signal jammers. Are there blind spots or leaks within this interference range? In some places where mobile phone signal jammers need to be installed, if there are base stations of operators, then the mobile phone signal will be relatively stronger. This situation will affect the interference range of the jammer. In order to achieve a good interference effect, it is necessary to purchase a jammer with higher power, and the cost will increase accordingly. In theory, the greater the transmission power of the jammer, the better the interference effect on mobile phone signals, and of course the cost will increase accordingly.

2. Normal operation time

Here refers to the trouble-free use time of the mobile phone signal jammer. Assuming that the jammer has a warranty of 1 year, but it actually runs stably for 3 years, the cost performance will be tripled. If the warranty is 1 year, it often fails in actual use. Although it is free of charge during the warranty period, the possible risks are immeasurable, and personnel resources are wasted. The corresponding cost performance will be reduced, and the user experience will be lowered.

3. Interference with the outside world

If the interference of the mobile phone signal jammer to the outside world is not considered, it is very easy to interfere with the mobile phone signal in most cases, as long as the interference power is increased. However, it is necessary to ensure that there are no blind spots and no leaks in the shielding area. The power of the jammer is large, which may cause great interference to the outside world. This requires that full consideration should be given when designing signal interference, and it should be controlled from a technical point of view to achieve accurate and efficient shielding without interference to the outside world.

4. Cost

The cost should follow the interference requirements and budget. You cannot blindly choose cheap products, nor can you simply think that high prices have good shielding effects. In actual selection, the interference effect of the mobile phone signal jammer is very important. It is also necessary to investigate its previous cases on the spot, test the interference effect, and then make a choice.
