Preparation
1. Choose a suitable test environment
To test a cellular signal blocker, you need to choose an environment without other interference sources to ensure the accuracy of the test results. Generally speaking, you can choose an open indoor environment, such as a classroom, conference room, etc.
2. Prepare the required equipment
In addition to the cellular signal blocker itself, we also need to prepare the following equipment:
Mobile phones of different brands and models (including those that support 2G, 3G, 4G, and 5G networks) Laptops or tablets for recording test data Wireless signal test software or applications for detecting mobile phone signal strength Power sockets and extension cords to ensure that the device is working properly.
3. Set test parameters
Before starting the test, we need to determine some key parameters, including:
The operating frequency band of the jammer (such as GSM, CDMA, WCDMA, LTE, etc.), the effective range of the jammer, and the network type and operator of the test mobile phone.
Test steps
1. Preliminary test
First, we conduct a preliminary test to ensure that the jammer is working properly. Place the jammer in the central location of the test environment and turn on the power. Turn on the jammer and observe whether its indicator light is working properly. Using different mobile phones, try to make calls, send text messages, and use mobile data near the cell phone jammer . If the phone cannot communicate normally, it means that the jammer is working properly.
2. Test signal coverage
Next, we need to test the signal coverage of the jammer. Place the phone at different distances from the jammer (such as 1 meter, 5 meters, 10 meters, etc.). At each location, use the wireless signal test software to record the signal strength of the phone. Make calls, send text messages, and use mobile data, and record the communication at each location. Repeat the above steps, gradually increasing the distance from the jammer until the phone can communicate normally. Through these tests, we can determine the effective coverage of the jammer and understand its shielding effect at different distances.
3. Test the effect of different frequency bands
In order to ensure that the jammer can work effectively under various network conditions, we need to test the shielding effect of different frequency bands. Set the phone to use different network types (such as 2G, 3G, 4G, 5G). Within the coverage of the jammer, use the wireless signal test software to record the signal strength under each network type. Try to communicate under each network type and record its effect.
Repeat the above steps to test different brands and models of mobile phones. Through these tests, we can understand the shielding effect of the jammer under different frequency bands and network types, and ensure that it can work effectively under various conditions.
4. Test stability
Finally, we need to test the working stability of the jammer. When the jammer is turned on, conduct continuous long-term tests (such as 1 hour, 2 hours, etc.). During the test, regularly record the signal strength and communication status of the mobile phone. Observe whether the jammer has abnormal conditions such as overheating and power failure.
Through these tests, we can evaluate the working stability of the jammer and ensure that it will not have problems during long-term use.
Through scientific testing methods, we can fully understand the working effect and stability of the cellular signal blocker. In practical applications, the reasonable selection and use of jammers will help maintain order in places such as examinations and public meetings and ensure information security. I hope this article can provide you with useful references to help you better understand and apply cellular signal blockers.
