Qi Cell Phone Charging Block

perfectjammer png2022/2/14

The basic principle of a cell phone jammer is to emit the same radio frequency signal as a cell phone. Since the frequency is the same, the mobile phone cannot distinguish which signal is a regular base station signal, thus achieving "interference". As long as there is a device on the same frequency as the phone, the base station will make a lot of "noise" when it tries to connect to the phone. You will find that the signal from the phone is not recognized, so you will refuse to communicate with the phone.

Radiation Blocking Cell Phone Case

At present, the main principle of Qi Cell Phone Charging Block and signal interference is to emit huge noise in the frequency band used by the mobile phone, interfering with the normal signal reception and transmission of the mobile phone. Not only is this little object often used to prevent cheating in exams, but it can also be used politically and militarily to prevent terrorist attacks. However, cell phone jammer is not like shopping for groceries, it is not just bought casually, otherwise it may be illegal.

The shielding distance of the equipment has a lot to do with the power of the equipment and the use environment. Several aspects affect the shielding effect: one is the output power of the equipment, the second is the working method of the shielding, and the third is the use environment (indoor or outdoor).The fourth is the strength of shielding the influence of the surrounding environment.

So what does the effective blocking range of Qi Cell Phone Charging Block depend on?

The power of the machine itself. There are many 5W machines on the market now, but the actual power is less than 1W. So it has to be real power. For low-power devices within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember that such a machine cannot go through walls. The density of cell towers near you. Today, many customers buy back their phones. 2G and 3G calls can be blocked, but 4G cannot. what is the reason? This is because there is a base station near you. Generally speaking, there is a base station within 100 meters. If you buy a low-power machine, it is basically impossible, because the signal of the base station is too strong. It is recommended to buy a low-power mobile phone jammer, more than 2W per channel.

Cell phone jammers operate on a straightforward principle

  1. they emit radio frequency signals that match those used by cell phones.
  2. This similarity in frequency confuses the cell phone, making it unable to distinguish between the jammer's signal and the legitimate signal from a base station.
  3. Consequently, the phone experiences interference, leading to communication disruption.
  4. This disruption can be advantageous in various scenarios, from preventing cheating during exams to thwarting potential terrorist attacks.

The effectiveness of a Cell Phone Charging Block or any cell phone jammer depends on several factors, including its output power, operating method, and the surrounding environment. Output power plays a significant role in determining the jammer's range and coverage area. Low-power jammers, typically below 1W, have a limited range of about 1-10 meters and cover areas of 10-30 square meters. It's crucial to ensure that the jammer's power output matches the intended usage scenario to achieve the desired results effectively.

Additionally, the effectiveness of a jammer can be influenced by external factors such as the density of cell towers in the vicinity. If there are nearby base stations emitting strong signals, low-power jammers may struggle to disrupt communication effectively. In such cases, it's advisable to opt for higher-power jammers with outputs exceeding 2W per channel to overcome the interference from nearby base stations.

When purchasing a cell phone jammer, it's essential to prioritize authenticity and reliability over low prices. Many low-cost options on the market may claim high power outputs but fail to deliver on their promises. Investing in a reputable and trustworthy brand ensures that the jammer operates as intended and complies with legal regulations regarding signal interference.
