How to judge the cost-effectiveness of mobile phone signal jammer?

When choosing a signal jammer, how should we judge whether the cost performance of a device is sufficient? You can consider the following four aspects:

1: High shielding efficiency

To put it bluntly, high shielding efficiency refers to whether the actual shielding effect has blind spots or loopholes. There may be communication base stations with strong mobile phone signals near some prisons. In order to achieve a good shielding effect, it will take a lot of materials and energy, and the cost will be corresponding. will be greatly improved. Therefore, the better the shielding effect, the higher the cost will be. In actual applications, the cell phone jammer of prison areas are generally higher, and there are slight loopholes and blind spots. Staff members who violate the regulations are likely to seize the loopholes and enable mobile phones to be used in the originally required shielding areas. There is no way to block the original intention on the mobile phone.

Two: No problem conditions

If the original requirement is 1 year without any problems, and if there are no problems in the actual application, it can reach 3 years, then the price/performance ratio is three times higher.

If there is no problem in the original requirement, the service life is 1 year. In actual use, faults often occur within less than half a year. Although there is a free warranty, the risks involved are immeasurable and staff resources are also consumed. The corresponding price-performance ratio is high. Very greatly affected.

Three: Impact of opening up to the outside world

If the impact of opening up to the outside world is not considered, simple shielding is relatively easy, just increase the shielding output power. However, it is necessary to ensure that there are no blind spots or leaks in the shielded area. The output power in the shielded area is very strong. If there is a little leakage, the impact on the opening to the outside world will be very large. This requires that the shielding design must be considered and technically controlled to ensure accurate and effective shielding without external impact.

Four: Cost

The cost should follow the blocking regulations and cost budget. You should not blindly follow the trend and choose cost-effective products, nor should you think that expensive ones are good. In the actual selection, user reviews are very important. You should visit and observe past examples and try blocking for yourself. Actual results, then make optimization.
