With the continuous development of technology, we have entered the era of informationization. Mobile phones, as a symbol of informationization, have become an indispensable tool in our daily lives and work. The transmission of signals between mobile phones is done through base stations. Without base stations, we would not be able to make calls, access the internet, or use payment functions. While mobile phones have brought convenience to our lives, there are certain places where their use is prohibited. To prevent the use of mobile phones in these specific locations, full band signal jammers have emerged. These devices can block mobile phone signals, preventing them from connecting to base stations and displaying “no service” on the screen.
The Working Principle of Full Band Signal Jammers:
As we all know, mobile phones work by establishing communication with base stations within a certain frequency range to achieve voice and data transmission. Full band signal jammers operate by scanning from the low-end frequency of the forward channel to the high-end frequency at a certain speed. They create same-frequency noise interference in the signal transmission between mobile phones and base stations, preventing the phones from establishing a connection. This effectively blocks the mobile phone signals.
The Relationship Between the Blocking Distance and the Proximity of Base Stations:
The blocking distance of a full band signal jammer is closely related to the proximity of the base station to the location where the jammer is used. When the location that needs to be blocked is close to the base station, the signal strength received by the mobile phone is high. It becomes difficult for the full band signal jammer to block the signals in such cases. In such situations, a higher power full band signal jammer is required to effectively block the signals. On the other hand, when the blocking location is far from the base station, the signal strength received by the mobile phone is weak. In this case, the full band signal jammer does not require a high transmission power to block the signals.
In conclusion, the effective blocking distance of a full band signal jammer is closely related to the distribution and proximity of base stations around the blocking location. The closer the base station is to the blocking location, the shorter the blocking distance of the full band signal jammer. Conversely, the farther the base station is, the longer the blocking distance of the full band signal jammer. Full band signal jammers play a crucial role in preventing the use of mobile phones in specific places where their use is prohibited. These devices ensure privacy, security, and compliance with regulations in various settings.
