Some customers expect to find a suitable cell phone signal jammer when they put forward their purchasing needs to us, which can not only satisfy the indoor environment, but also hope that in some special cases, they can be taken outdoors, and require outdoor Under the environment, the effective shielding distance can be guaranteed to reach tens of meters. Then the question arises: Can indoor mobile phone signal jammers be used outdoors?
Usually, according to the two different environments of indoor and outdoor, mobile phone signal jammers also correspond to two major classifications, among which the indoor ones are basically low-power models, while the outdoor ones are high-power ones. type mobile phone signal jammer.
How to judge whether the mobile phone signal jammer used indoors can be used outdoors? If it is judged from the actual use effect, that is, whether the effective shielding distance can be maintained, when the indoor low-power model is replaced with an outdoor environment, the strength of the outdoor mobile phone signal is almost far greater than that of the indoor environment. , the difference in signal strength between the two will reach about 10dB, so once you use a low-power shielding device outdoors, you will find that its effective shielding distance will be severely shortened, and in extreme cases it is more likely that even if it is 1 meter away from the shielding device The distance, the mobile phone can also be used normally.
Analyzing the above situation in reverse, if an outdoor high-power mobile phone signal jammer is placed in an indoor environment, there is no doubt that there is absolutely no problem with the shielding effect indoors, and even the shielding effect will be far greater than that in the outdoor environment. in the effect. However, there are very few customers who use this kind of high-power mobile phone signal jammer indoors, and generally only large-scale theaters, museums or large conference rooms will use this method.
High-power mobile phone signal jammers are not recommended to be used in indoor environments. The main reasons are: First, it is relatively large in size and needs to occupy a large position or space when installed indoors. The second is that its chassis will be equipped with a high-speed rotating cooling fan, which will generate a certain amount of wind noise. Third, the purchase price of high-power mobile phone signal jammers will be relatively high. The fourth is to consider the impact of electromagnetic radiation safety, and it is necessary to ensure that the installation position of its antenna is kept at a suitable and safe distance from the human activity area.
