How to choose a mobile phone signal jammer?
How to choose a mobile phone signal jammer mainly considers the following aspects:
First, consider where the cell phone jammer will be used. For example, student dormitories are often installed in corridors to screen the rooms on both sides. Then, we should consider those machines that can cover the entire dormitory.
Second, we choose the mobile phone signal jammer functionally. In the fourth generation communication era before 2020, we can use 4G mobile phone signal jammers in different places. Some of these places have not yet communicated through 5g, so we can choose a more cost-effective 4G mobile phone signal jammer. With the global shortage of 5g communication debugging equipment and chip shortage in the 5g era in 2021, the raw material prices of 5G signal jammers are also getting higher and higher. If the budget is enough, we can consider a new 5g mobile phone signal jammer. What we call 4G mobile phone signal jammers now include China Mobile and Unicom's three-network 2G, 3G and 4G mobile phone signal jammers. 5g mobile phone signal jammers now include China Unicom 3 network 2G, 3G, 4G and 5G mobile phone signal jammers.
Third, choose a cell phone signal jammer. First, choose products from formal channels with brands. Product machines include brand, model, machine packaging, company name, execution standards, warranty card and other information. If you purchase Sanwu products, we cannot guarantee future after-sales service.
Fourth, when choosing products, we cannot just look at a few mobile phone signal jammers. For example, if we compare and reference the same 10 cell phone signal jammers, we need to know how many tiles the output power is of each, and what the total power is. Only with the same power can we better compare product effects. If the price difference is relatively large for machines with the same power and the same number of channels, then we should try our best to ask the factory to dismantle the machine, check whether the debugging frequency is square, check whether the chips used are completely original, and whether there are chips.
