  To ensure that the selected shielding equipment truly meets the use needs and has safety and compliance guarantees, please be sure to pay attention to the following points:

  1. Clarify the use location and coverage area

  First, confirm the use environment (such as classrooms, conference rooms, prisons, examination rooms, etc.) and the space range that needs to be shielded, so as to select products with appropriate power and antenna configuration to avoid shielding blind spots or power waste.

  2. Confirm the type of signal to be shielded

  Currently, the mainstream shielding frequency bands include:

  Mobile communication: 2G / 3G / 4G / 5G

  WiFi network: 2.4G / 5.1G / 5.8G

  

  Device that supports the required frequency band should be selected according to the actual communication environment and control requirements. If necessary, a full-band signal jammer can be selected.

  3. Check whether there is a signal enhancement source in the surrounding area

  If there is a communication base station tower, indoor signal amplifier or micro base station near the use location (within about 500 meters), it may affect the shielding effect. It is recommended to conduct field tests and consider increasing the number or power of wifi jammers to deal with interference sources.

  4. Check the functional expansibility

  Some occasions have high requirements for equipment management. It is recommended to give priority to products that support the following extended functions:

  Long-term stable operation capability

  Uniform switch control (such as simultaneous control of multiple classrooms)

  Timed switch function

  Equipment operation status detection (overheating alarm, fault prompt, etc.)

  5. Confirm that the product is legal and compliant

  Do not buy "three-no" products. When purchasing, please confirm:

  Whether it is produced by a regular manufacturer

  Whether there is a clear brand logo and technical parameters

  Whether warranty service and after-sales support are provided

  6. Check the authoritative test report and health and safety standards

  High-quality shielding devices should provide the following test reports:

  Electromagnetic compatibility test report

  Human radiation safety assessment

  Ensure that the product will not interfere with human health or other electronic equipment when in working condition.
