Does the mobile phone signal blocker need to be adjusted?
Many places need a signal shielding device, but many people do not know the installation method of the signal shielding device. Some people think that the mobile phone signal shielding device can be used directly by connecting to the power supply, but some people think that the frequency needs to be adjusted, and the signal shielding device works It's hard to tell whether or not.
Interference between mobile communication systems
1. In-band interference: The CDMA transmitting signal acts directly on the GSM receiver as in-band noise directly or through intermodulation and other methods, resulting in a decrease in the sensitivity of the GSM receiver. This type of interference is further divided into transmitted spurious interference and intermodulation interference;
2. Out-of-band interference: When the out-of-band interference is strong to a certain extent, it will cause the receiver to be full and blocked, thereby affecting the reception function of the GSM system. This type of interference is also called blocking interference.
The use of the mobile phone signal screener is convenient for our life, but its signal is easily interfered, so it is still necessary to adjust its frequency.
Since the wireless network is already flooded, there are often some networks that interfere with each other, which indirectly leads to the poor wireless network in your home. So how to block these signals? The editor of the mobile phone blocker will answer it for you!
The mobile phone jammer shares the method of shielding the signal:
1. Increase the distance and physical obstacles between the mobile phone, etc. and the WiFi router, which can weaken the transmission and reception of WiFi signals;
2. There are certain radio interference sources around the WiFi router or the mobile phone, which will also affect the transmission quality of the wireless signal between the mobile phone and the WiFi router, such as signal jammers.
3. Log in to the web background of the WiFi router and artificially lower the transmit power of the WiFi signal;
4. Place the WiFi device in an environment covered by metal materials to shield the WiFi signal.
