Why Exam Room Signal Jammers Are Cheaper Than High-Power Signal Jammers

Every year, various types of exams are conducted in an orderly manner, and exam room signal jammers are an important measure to maintain fair exams. These devices are used in a wide range of exams, and exam authorities allocate special funds each year for the purchase or upgrade of these signal jamming devices. However, some customers may wonder why exam room signal jammers seem to be cheaper compared to high-power signal jammers with similar functions. In this article, we will analyze the reasons behind this price difference.

Factors Affecting Product Pricing:

The price of a product is mainly determined by factors such as the cost of electronic components, assembly and process costs, batch production volume, and reasonable profit and taxes.

Cost Analysis:

Exam room signal jammers have their production costs calculated based on the following factors. The cost of electronic components mainly includes the design of electronic circuits and the selection of electronic components, which accounts for about one-third of the product’s selling price. Assembly and process costs mainly involve manual assembly, testing, and debugging processes, which also account for about one-third of the total product cost.

Batch Production and Cost Reduction:

To achieve a lower price for exam room signal jammers, it is necessary to have a certain production volume. For example, we produce each batch according to a quantity of 1000 or 2000 units for unified procurement of materials. Only by reaching this level of purchase volume can the unit prices of various electronic components be more favorable. Additionally, batch production allows for optimal scheduling of production line workers and rational distribution of various processes, thereby maximizing work efficiency and reducing labor costs. The large production volume, fast production cycle, and low cost of bulk electronic component procurement ensure that exam room signal jammers are relatively inexpensive.

Comparison with High-Power Signal Jammers:

In contrast, high-power signal jammers have lower production volumes, which results in higher costs for electronic component inventory. Their small-scale production and longer production cycles also lead to relatively higher labor costs.


Exam room signal jammers are cheaper compared to high-power signal jammers due to their large production volume, fast production cycle, and low cost of bulk electronic component procurement. These factors contribute to the affordability of exam room signal jammers. Understanding the cost factors behind product pricing helps customers make informed decisions when choosing signal jamming devices for their specific needs.
