Diy Portable Cell Phone Jammer
When choosing a mobile phone signal jammer, how should you judge whether the price/performance ratio of a machine is sufficient? You can consider the following four aspects: Master with Diy Portable Cell Phone Jammer manufacturers. To put it bluntly, the high efficiency of shielding is whether there are blind spots and loopholes in the actual effect of shielding. Around some prisons, there are likely to be sending communication base stations with strong signals on mobile phones. In order to better achieve a very good shielding effect, it will take a lot of raw materials and vitality corresponding to the cost. Will be greatly improved. therefore, cell phone jammer The better the actual shielding effect, the higher the cost. In specific applications, the shielding regulations of the prison area are generally higher, and there are some loopholes and blind spots. The staff who violate the regulations are likely to grasp this system loophole, and promote the application of the mobile phone in the originally required shielding zone. Method to shield the original intention on the mobile phone.
If the original requirement is that there is no problem and the service life is 1 year, and there is no problem in the specific application to achieve 3 years, the cost performance is 3 times higher. If the original requirement is that there is no problem, the service life is 1 year, and common failures often occur in specific applications less than half a year. Although it is completely free of warranty, the risk caused is immeasurable, staff resources are also consumed, and the corresponding cost-effectiveness is high. Was very much affected. If the impact of opening up is not considered, it is relatively easy to simply shield, just increase the shielding output power. But make sure that the Diy Portable Cell Phone Jammer shielding area has no blind spots and no leakage. The output power in the shielding area has a high compressive strength. If there is a little leakage, the impact of opening to the outside world will be very large. This stipulates that in the case of shielding design schemes, it needs to be considered and controlled in many aspects technically to ensure accurate and reasonable shielding and not open to the outside world. Costs must follow the shielding regulations and cost budgets. You cannot blindly follow the trend and choose cost-effective products, and you must not think that the expensive is good. In the specific selection, user evaluation is very important. You should visit the past examples and try the shielding. The actual effect will be optimized.
