The mobile phone signal jammers purchased by the school in previous years did not have the function of interfering with 5G signals because 5G had not been launched when they were originally purchased. In the current use of signal shielding in examination rooms, they can no longer shield 5G signals. This leaves school examination room users faced with the problem of how to upgrade or replace the original mobile phone signal jammer. So how should you choose a 5G signal jammer during school exams? signal jammer
School examinations require the use of 5G signal jammers for examination room management to ensure that candidates will not be affected by wireless signals from the outside world. Therefore, it is recommended to consider the following points when choosing a 5G signal jammer for school exams:
1. First, make sure that the selected 5G signal jammer can block the signal in the 5G frequency band. Generally speaking, the frequency bands of 5G signals are divided into mobile 5G (2515MHz-2675MHz, 4800-4900MHz), China Unicom 5G (3500MHz-3600MHz), China Telecom 5G (3400MHz-3500MHz), radio and television 5G (703MHz-733MHz, 758MHz-788MHz, 4900MHz -5000MHz), so you should purchase a jammer that supports these frequency bands.
2. Choose a brand or model with good shielding effect. You can refer to some well-known domestic and foreign brands or models with a certain reputation in this field for comparison. Of course, you should also choose a signal jammer model with appropriate power based on your own usage scenario and environment to purchase a 5G signal that suits your needs. jammer.
3. Consider purchasing a multi-functional model that has other functions besides shielding, such as shielding GPS, Bluetooth, WIFI and other wireless signals, in order to adapt to the shielding requirements of different types of communication equipment in exam scenarios.
4. Finally, the price of the signal jammer must be considered. After all, the budget cost of some school examination rooms is limited, so it is necessary to choose signal jammer products with high cost performance. Of course, in addition to considering the price, the quality and performance of the 5G signal jammer should be given priority. Choosing a high-quality and high-performance 5G signal jammer can provide better protection and security for the exam process.
