Currently, the existing cell phone jammer in colleges and universities mainly have three formats, 2G, 3G, and 4G. The current upgrade ideas mainly include the following. There are mainly the following types of systems.

(1) Upgrade by replacing circuit boards, antennas and other components

However, this method has higher technical requirements and requires better upstream and downstream channels to digest and replace compliant devices. It is mainly suitable for newer brand signal jammers. The difficulty lies in the need to detect and determine the available parts and determine the specifications of the parts before upgrading and replacement. The essence is still a value-added service, and the actual value created for miserly is not high due to the large workload.

For example, a batch update of the brand's 3G mobile phone signal jammer is a 4C which costs 197 yuan, and a brand new 4G mobile phone signal jammer of its brand needs 240 yuan.

(2) Upgrade by adding sub-function modules)

This method has higher technical requirements. It is necessary to be very clear that the power supply, output and other standards of the original mobile phone signal jammer are usually limited to the brand. Compared with the method of replacing the components to upgrade, this upgrade method actually creates lower value for customers Because of the advantages of integration, it is relatively inconvenient for customers to use. At the same time, there is a problem of electromagnetic compatibility, and the external equipment itself increases the inconvenience of storage. On this basis, the cost of the material itself is even higher than replacing the motherboard. For example, A 4C module of a mobile phone signal jammer that adds "plug-in" needs 207 yuan.

(3) Complete replacement)

From the actual effect, this method is actually the best way to achieve the technical goal. Because it retains portability and can better reduce the failure rate. Of course, the price is also the most expensive. Generally, a new 4G mobile phone signal jammer needs Around 240 yuan. Some manufacturers adopt the so-called The trade-in marketing strategy will essentially make up for customers. Although the overall price is slightly less than that of new purchases, the actual marketing space is very limited. For example, the "trade-in" provided by a certain manufacturer requires customers to make up about 180 yuan per unit, which is equivalent to 75% of the price of a brand new machine.
