How to choose a mobile phone signal jammer in the school examination room?

When choosing a cell phone signal jammer for a school exam room, there are several factors to consider:

1.Consider coverage:

Evaluate the specific location within the school where the jammer will be used. For example, if it is in a student dormitory, it may be appropriate to install the jammer in the corridor to cover the rooms on both sides. In this case, choose a device that can effectively cover the entire dormitory.

2.Evaluate functionality:

Before 2020, in the era of fourth-generation communications, it was sufficient to use a cell phone signal jammer that was compatible with the available communication frequency. Since not all centers have transitioned to 5G communications, cost-effective cell phone 4G signal jammers are sufficient. However, with the advancement of 5G communications and the shortage of 5G communication commissioning equipment worldwide, cell phone 5G signal jammers are becoming more and more expensive. If the budget allows, consider purchasing a new 5G cell phone signal jammer, while 4G signal jammers generally cover 2G, 3G, and 4G signals from all major mobile network providers.

3.Choose a well-known brand:

When choosing a cell phone signal jammer for an exam room, you should choose products from well-known brands through official channels. The product packaging should include information such as brand, model, company name, implementation specifications, and warranty card. This ensures reliable after-sales service and support.

4.Compare products:

Don’t just focus on the cell phone signal jammers in the exam room. Instead, you can compare and evaluate different models of 10-channel signal jammers. Pay attention to the output power of each channel and the total power output, usually in watts. By comparing devices with the same power and number of channels, you can better evaluate the effectiveness of the product. If the price of machines with the same power and the same channel configuration varies greatly, you can consider asking the manufacturer to disassemble the machine to check the frequency calibration, whether it uses a brand new original chip, whether each channel has the required components, etc. These are important references for making decisions.
