From March to May every year, it is the peak season for the sales of mobile phone signal jammers in the examination room. Many schools are making sufficient preparations for the college entrance examination in June and the high school entrance examination in July, and invest special funds for standardized examination rooms. Construction, as an important safeguard against cheating in the examination room, the mobile phone signal jammer in the examination room is an extremely important link, so why does the school spend a lot of effort on these aspects every year? Does the mobile phone signal jammer in the examination room need to be replaced every year? What is its failure rate?

In fact, it is not true that the school upgrades the mobile phone signal jammers in the examination room every year. It is just that there are a large number of schools. Different schools do not carry out a project at the same time. They will formulate according to their own needs and budget. The specific implementation time is usually replaced every 4 to 5 years. During this period, inspection and maintenance will only be arranged every year.

The upgrading cycle of the mobile phone signal jammer in the examination room is generally synchronized with the upgrading time of the mobile phone communication system, or slightly lagged behind by 1 to 2 years. For example, more than ten years ago, when 3G mobile phones began to spread widely, schools needed to replace the mobile phone signal jammers in the examination room that only had the function of shielding 2G mobile phones with ones that could shield both 2G and 3G. In the same way, when the replacement cycle of 4G and 5G comes, the corresponding replacement of mobile phone signal jammers in the examination room will follow up.

The replacement cycle is relatively long, at least once every 4 to 5 years, but the daily troubleshooting of mobile phone signal jammers in the examination room should be persisted for a long time, otherwise it will lead to low equipment integrity and failure rates On the high side. There are many reasons for the high failure rate, not only including the frequency of inspection and maintenance, but also closely related to the quality, process and use of the product itself, whether the transfer and transportation are safe, and whether the user cares about and protects the product.

After years of statistics and feedback, as a manufacturer of mobile phone signal jammers in the examination room, after nearly 20 years of experience accumulation, the quality and craftsmanship of the product itself have been greatly improved, and the failure rate in this regard has been reduced. down to a very low level. Today's products are even more packaged with an overall shell, which is no longer like the past: antennas, power supplies, etc. are all connected externally, and now they are all built-in, which also minimizes the possibility of man-made damage to the device.
