Wireless jammer: Gas stations are not allowed to make calls

The equipment at the gas station is controlled by a computer. The signal from the mobile phone interferes with the normal operation of the device and leads to inaccurate measurements. More importantly, sparks occur during the call from the cell phone, which can easily cause a fire and explosion at the gas station. The current cell phone signal is almost everywhere and all electrical devices are surrounded by it. When the mobile phone is not in use, this type of surrounding signal has minimal interference with other electrical devices. This is because when the mobile phone is not in use, there is no data exchange between the mobile phone and the base station and it is impossible to generate a sudden change signal. The electrical equipment is surrounded by a relatively stable electromagnetic field, that is, a static electromagnetic field. The interference of this static electromagnetic field with the electrical equipment is almost zero.

At the same time, gas stations should put up obvious signs prohibiting cell phone calls and make the safety knowledge widely known so that people understand that cell phone calling at gas stations undoubtedly goes with the tiger. There have been many fires caused by cell phone use across the country. A gas station in Henan caused an explosion when the driver used his cell phone to refuel, causing a serious accident that resulted in many deaths and injuries. There are also many cell phone fire hazards at gas stations in Shenzhen and Chongqing.

The wireless jammer has been specially designed and manufactured using international advanced shielding technologies to meet the market demand. The device has undergone a brand new upgrade. By changing from 5 to 6 channels, the shielding effect of the device itself on the signal is increased. At the same time, the newly added 4G frequency band solves the disadvantages that other products cannot shield the 4G frequency band, and the shielding effect is better than other similar products. The shielding effect is stronger, the performance is more stable, and it is easier to be recognized and accepted by customers.
