Whether the mobile signal jammer will interfere with the Lora signal, we must first understand what the Lora signal is. Lora is a low-power LAN Wireless Standard created by Semtech company. Lora (long range radio) long-distance radio is characterized by its greater propagation distance than other wireless modes under the same power consumption conditions, realizing the unification of low power consumption and long distance. It is 3-5 times larger than the traditional radio frequency communication distance under the same power consumption. 

The operating frequency band of Lora includes 433，868，915MHz, etc. Because of its low frequency and excellent diffraction performance, it can transmit 2-5 kilometers in urban environment.

Knowing the Lora signal, we can see that the frequency used by the Lora signal is 433868915mhz. If the frequency of the interference signal transmitted by the mobile signal jammer is repeated with the frequency used by the Lora signal, the mobile Signal Jammer will interfere with the Lora signal. If there is no repetition, the Lora signal will not be interfered.
