If your GPS jammer is a direct current (dc) device, you need to plug it into a usable power source, and that's it. It can also be used without a built-in battery, such as a car GPS jammer, which needs to be plugged into the car to lighten the cigarette The socket can be used normally.
GSM signal is a kind of mobile phone signal, so GSM jammer belongs to mobile phone jammer. If you only want to block the GSM signal, you only need to select a GSM jammer that will only interfere with the GSM signal of the device, but if you want to block other mobile phone signals in addition to the GSM signal, such as 3G, 4G or even 5G signals , Then I suggest you buy a GSM 3G 4G 5G signal mobile phone jammer.
A high power jammer means that it can interfere with more signal frequency bands and has a wider range of interference. But like other signal jammers, it is not harmful to the human body. It will only help the devices that you want to prevent signal interference, such as mobile phones, and provide you with a good environment.
In recent years, prisons, labor camps, and detention centers across the country have invested funds to build or rebuild cell phone jammer systems. It is hoped that illegal use of mobile phones will be eliminated, mobile phone management in supervision sites will be strengthened, and supervision work will be carried out smoothly.
As we all know, a good signal jammer needs to cover many aspects, not only the product has higher performance and better quality assurance, but it also has an affordable price, after all, there are many choices. Today’s market, but customers often want to choose the one that best suits their needs. This is also to achieve the most cost-effective consideration.
The cell phone jammer emits interference signals like the frequency that the mobile phone takes over. It just hinders the connection between the mobile phone and the base station so that the mobile phone is always in a state of no signal search, and it will never cause harm to the mobile phone!
Whether the test room signal jammer is effective depends on the environment around the test room and whether the quality of the test room signal jammer purchased is good. The test room environment is mainly to see if there are any base stations nearby. If there is a base station, it needs to be equipped with a little more shielding device.
Is there a base station near the school? In the process of construction, we often find that customers tell us that the signal jammer is not effective. 2G3G can be shielded, which means that the call signal can be shielded, but the 4G signal cannot be shielded. In fact, the power of each jammer is different. Generally, the power of 4G1 and 4G2 is about 2W, which means 33db.
Generally, the area of the examination room is less than 100 square meters. The installed cell phone signal jammers are all low-power. Low-power products are only used in open and small areas. And the current test room cell phone jammer technology is very mature, only shielding the downlink , Does not shield the upstream.
The first way is to surf the Internet via mobile phone operator signals. As soon as the shielding device is turned on, the mobile phone cannot receive the operator's signal, which makes it impossible to make calls or text messages. Naturally, the Internet cannot be accessed, and the shielding is effective.
It is understood that GSM jammer on the market can limit cell phone signals to 500 meters away from the launching station. The shielding radius is adjustable, and the coverage area reaches more than 30 square meters. The mobile phone signal shielding device can only shield the mobile phone signal and does not affect other electronic equipment.
The smart functions of mobile phones are now expanding. In addition to basic call and text messaging functions, they also have digital cameras, camcorders, voice recorders, More application functions such as Internet access. Why is it recommended to install cell phone jammer on the factory floor?
