The frequency jammer in the form of backpack, which can also be called portable frequency jammer, is mainly used in the outdoor environment or the treatment of temporary emergencies. Because its appearance is the same size as a traveling backpack, a normal adult man can carry it with him. Then the customer's problem comes. After this backpack type frequency jammer is carried on the body, so many antennas on the equipment are really close to the human body, especially the brain. In this way of use, don't you worry about the harm to the human body?
It's not too much for customers to worry about this. Frankly speaking, the built-in shielding module of this knapsack frequency jammer usually has a RF transmission power of about 10-20w. After being transmitted through the antenna, if it is really turned on under the state of carrying, the generated electromagnetic radiation still has a certain intensity. However, electromagnetic radiation is not nuclear radiation, it is not so terrible. The injury procedure to human body is far less serious and terrible than people think.
If this medium power frequency jammer is only used for a short time and is not used repeatedly every day, the degree of electromagnetic radiation is almost negligible to human body.
Moreover, the knapsack frequency jammer is usually powered by the built-in battery. The continuous working time powered by the battery is generally only 1-2 hours, so it will not produce electromagnetic radiation to the human body for a long time.
Finally, we would like to emphasize that in real application scenarios, the frequency jammer can only be turned on when the human body is carrying it, unless it is a military or special police or special service personnel under very special task situations. In most cases, this knapsack frequency jammer is mainly used to facilitate carrying or quickly transfer the target site, rather than being turned on for a long time and continuously in motion.
