Nowadays, many schools install signal jammers to supervise students' examinations. After all, the signal interference range of these interference devices is limited, and generally the whole teaching building needs to be interference processed, which naturally requires the installation of a large number of interference instruments and a large amount of funds. Then, what is the basis for pricing these jamming equipment products?

The environment used by the user determines the price of the signal jammer. It is assumed that there is no base station nearby; The room is open and there is no shelter; The interference of indoor rooms is relatively small; Generally, the use power of the jamming equipment required in this case does not need to be too large, and the cost of these jamming equipment will not be too high. On the contrary, if users have high requirements for the use of signal jammers, their prices will be high, and of course the effect will be better. Different types of signal jammers are definitely different in use, and the prices of these jammers are naturally different. Basically, if the price of the jammer is obviously high, then all kinds of functions should be available. In terms of technology, it must be better than ordinary mobile phone signal jammers, and all kinds of signals should be jammed. If only a few frequency bands are interfered according to the demand, such signal jammers can make targeted interference to the field signals, and the price may be relatively low. When purchasing some jamming equipment, we should still consider the actual situation. Of course, the price of different jamming requirements is different. After all, one price is one goods.
