"What is the general shielding range of a mobile phone signal jammer?" "100 square meters, what size of mobile phone signal screen is appropriate?" These are the questions that most customers who want to buy a mobile phone signal jammer will ask. question.
Before answering this question, let us first understand the principle of mobile phone signal jammer.
The principle of the mobile phone signal jammer is to interfere with the downlink signal of the base station, thereby blocking the mobile phone signal.
There are currently two ways to interfere with base station downlink signals. One is high-power suppression, which uses a device to send out 2\3\4\5G, white noise signals in the same frequency band as the base station signal, drowning out the original signal of the base station. , thereby achieving shielding of mobile phone signals. This method is a traditional method and will interfere with the uplink signal of the base station. https://www.silencejammer.com/
The other is signaling-level intelligent shielding technology. This type of equipment is represented by ZXTY-GR03. The equipment scans the public network signal by scanning the antenna, and then blocks the public network base station signal through signaling-level instructions, simulating the public network base station signal to the environment. It emits false base station signals to induce mobile phones, thereby blocking mobile phone signals. This type of device has low power and good shielding effect. It is the development trend of the new generation of mobile phone signal jammers.
What determines the effective blocking range of a mobile phone signal jammer?
①The power of the mobile phone signal jammer itself
There are many machines on the market now that are said to be 5W, but the actual power is less than 1W. Therefore, it must be actual power. For low-power machines within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember, this machine cannot penetrate walls.
②The density of nearby base stations
Many customers now buy back their phones and can block 2G and 3G calls, but not 4G calls. Why? Just because there is a base station near you. Generally speaking, there are base stations within 100 meters. If you buy a low-power machine, it will basically not work because the signal strength of the base station is too strong. It is recommended to buy a medium-power jammer, with a ratio of more than 2W per channel.
③Field wall environment
