When using a cell phone jammer, you will inevitably encounter some problems. So, what are the common problems? Let's learn together:
1. Why do some mobile phone signal indicators still show signal when the unit is working?
Answer: This is just a hypothesis. In fact, the mobile phone is no longer able to communicate at this time. When pressing the "Unplug" button, you will find that there is no signal indication on the signal indicator.
2. Will mobile phone signal jammers interfere with the normal operation of other electronic devices?
Answer: No. The reason is that the electromagnetic signal emitted is completely within the specified mobile phone operating frequency band and can only block mobile phone communications. Moreover, such signals are always in a relatively static state and will not affect any electronic devices.
3. Is there any difference in the effective shielding distance of signal jammers for sale when used indoors and outdoors?
Answer: Yes. The effective shielding distance of the telephone signal screen (30-40 meters) generally refers to the indoor distance. In open areas outdoors, the effective distance of guardrails can reach hundreds of meters. It should be noted that whether it is indoors or outdoors, the effective shielding distance of the shield is related to the environmental conditions at the time, such as farther away from the base station and farther away from the location. Therefore, when using this machine, you must fully consider this factor to avoid shielding dead spots and affect the shielding effect.
