Some customers who use it for personal use are very fond of small and compact wireless signal jammers that can be carried around. These customers have always hoped to find a shielding device with the following characteristics: the device should be as small in size as possible and very light in weight, so that the entire device can be fully grasped with one hand, or can be placed directly in the pocket of the clothes. It has strong concealment and will not be recognized by others at a glance. At the same time, it is also required that this wireless signal jammer can be used in outdoor applications, and can shield more than ten meters or even tens of meters in outdoor environments. Finally, it will be required that this shielding device is powered by batteries, and can work continuously for more than 2 hours after being fully charged. . .
Faced with such multiple requirements, we can only smile wryly: Customer, this is obviously idealized. In the field of wireless signal jammers, equipment that can meet all the above requirements at the same time, I am afraid that I have searched all over the world for manufacturers. Can't make a product like this.
Why do you say that? Because the customer's request itself contains several contradictory technical points. For example, the relationship between the working hours of battery power and the power of the device and the weight of the whole machine. If a wireless signal jammer wants to achieve a complete shielding effect, it must emit a shielding signal of sufficient strength to suppress the signal from the mobile phone base station, and the transmission power of this wireless signal jammer must not be lower than several Ten watts, its power consumption can even reach more than 100W. People who understand basic physical knowledge can know through simple calculations that if a battery is used to power an electrical device of at least 100W, it must be allowed to work for at least 2 hours. , This will inevitably be a very large battery pack, and the weight of this battery pack alone may reach about 3KG.
The above is just an analysis of the contradiction between battery power supply time and weight. Next, let’s look at the contradiction that is more difficult to solve: the requirement is to use a wireless signal jammer in an outdoor environment, and the shielding distance needs to reach tens of meters. If you want to achieve For such a requirement, it is necessary to increase the transmission power of each frequency band in the wireless signal jammer, which will lead to an increase in power consumption due to the increase in transmission power, and the increase in power consumption will lead to a serious increase in battery power supply time. shortening, when the battery capacity is increased to solve the problem of long power supply time, it will bring about a significant increase in battery weight and an increase in the appearance size of the device...
The repeated superposition of these multiple contradictions and conflicts is a vicious circle, and the final conclusion is that the wireless signal jammers carried outdoors can no longer be concealed at all.
