In the exam season each year, all parties begin to prepare for the exam. The invigilator has various tricks to prevent high-tech cheating. Among them, the special shielding device for the exam room is still an anti-jamming device. However, Texin Electronics, as a well-known manufacturer of cell phone jammer, reminds that there are many types of jammers, and users should clarify their needs before purchasing to avoid poor shielding effects and accidents in the examination room. Those who are still paying attention to the method of use. Correctness.

First of all, I want to clarify the place of use. Most schools use test room-type mobile phone shields that are suitable for long-term work and are durable. The second is how big are we in the shielded area? For example, if it is a room of 100 square meters or a venue of thousands of square meters, if the area is large, the power should be larger, and if the area is small, consider choosing the shielding power adjustable. Then there is which frequency bands need to be shielded. Are China Mobile, China Unicom, Telecom and CDMA all shielding? Still only need to shield part of the frequency band.
