If you want to know whether the cell phone signal jammer will interfere with the ZigBee signal, you must first understand what the ZigBee signal is. Zigbee technology is a wireless communication technology applied in short distance and low speed. Zigbee was also called "HomeRF Lite" and "FireFly" technology in the past, and they are collectively called Zigbee technology. It is mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate, as well as typical applications with periodic data, intermittent data and low response time data transmission.

Latest Desktop Portable 100W 4G 5G GPS WiFi 2.4G 5.8G Frequency Cell Phone Jammer ZigBee is a wireless connection that works in 3 frequency bands: 2.4GHz (popular in the world), 868MHz (popular in Europe) and 915 MHz (popular in the United States). According to the signal frequency used by ZigBee, it can be concluded that the cell phone jammer will not interfere with the ZigBee signal. The signal frequency band used by the mobile phone signal jammer is 868MHz (popular in Europe) and 915 MHz closest to the frequency band used by ZigBee, but there is no frequency band that repeats the output signal of the mobile phone signal jammer. Everyone knows that the signal emitted by the mobile phone signal shielding device is in the same frequency band as the mobile phone signal. The lowest frequency band is 870-880 of CDMA, and the frequency band of GSM is 930-960. Now the 5G signal frequency of radio and television is 700MHz, and it does not repeat with the ZigBee signal. Yes, so the signal emitted by the cell phone jammer will not interfere with the ZigBee signal.

If you want to know whether the mobile phone shielding device will interfere with the LoRa signal, you must first understand what the LoRa signal is. LoRa is a low-power local area network wireless standard created by semtech. LoRa (Long Range Radio) long-distance radio. Its biggest feature is that it can travel farther than other wireless methods under the same power consumption conditions, achieving low power consumption and Long-distance unification, it expands 3-5 times the distance of traditional wireless radio communication under the same power consumption. The working frequency band of LoRa includes 433, 868, 915MHz, etc. Because of the low frequency and excellent diffraction performance, it can transmit 2-5 kilometers in urban environments.

Frequency Jammer

After understanding the LoRa signal, you can see that the frequencies used by the LoRa signal are 433, 868, 915MHz, and then we will understand the basic principle of the cell phone jammer. The signal emitted by the phone jammer is a white noise signal in the same frequency band as the mobile phone signal. In the field of use, the signal strength of this white noise is higher than that of the mobile phone signal, so the mobile phone blocker can block the mobile phone on the scene. On the contrary, the mobile phone blocker cannot block the mobile phone signal on the use site.

It can be seen that the frequency band of the signal transmitted by the mobile phone jammer does not overlap with the frequency band of the LoRa signal, so it will not cover the frequency band of the LoRa signal, so the signal emitted by the mobile phone jammer will not interfere with the LoRa signal.
