The wifi jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as searching the network, no signal on the mobile phone, no service system, etc.
After the wifi signal jammer works for a period of time, the casing becomes hot. Will it damage the machine after working for a long time?
Because all the jammers need to amplify the power of the radio frequency signal, which will generate a relatively large power consumption conversion, so it is a normal phenomenon for the wifi jammer device to heat up. In the design of shielding products, the aluminum alloy heat sink is generally used as the product shell or built into the product as an auxiliary group to dissipate heat. This ensures long-term stable operation.
However, many manufacturers cut corners and materials in order to save costs, using very thin radiators or no radiators at all, and not equipped with cooling fans, so that the working temperature of the wifi frequency jammer is too high, causing damage to the machine. Therefore, the working temperature of the machine is also to judge the quality of the signal jammer. One of the bad standards, the working temperature of qualified shield products from regular manufacturers is generally higher than 50 °C, and supports long-term uninterrupted work, the power and frequency are very stable, and there will be no significant drop in power or frequency drift beyond the standard requirements. , resulting in the problem of poor shielding effect and no shielding effect.
The parameter indicators of all devices will change with the change of temperature. If the temperature is too high, the stability of the device will be affected. For example, when a shielded area has signals on both sides of the interference frequency band, the shielding is usually effective. When the temperature increases, the frequency will be larger. Offset, the interference frequency deviates from the original working frequency, which makes the original shielding lose its effect or causes the shielding effect to be good and bad. Temperature affects the service life of equipment, and its general rule is that the service life is inversely proportional to the square of the temperature increase
