Are cell phone signal enhancement stickers really useful?

  According to most merchants, the principle of mobile phone signal enhancement stickers is to extend the wavelength of the built-in receiver of the mobile phone to enhance the range of signal reception, thereby improving the fluency of calls and network functions.

  A certain merchant said to a reporter from Chinanews.com that it was “definitely useful” and sent a demonstration video. The video showed that the signal became “full” after being pasted, saying that the principle is to extend the wavelength to increase the signal receiving range.

  According to the "Internet Joint Rumor Refutation Platform", in fact, mobile phone signal stickers have no effect on mobile phone signals.

The main factors that affect the strength of mobile phone signals are the distance of the signal base station, the density of people and the mobile phone antenna.

The so-called mobile phone signal enhancement stickers are neither powered by electricity nor connected to the built-in antenna of the mobile phone. It is impossible to increase the signal in the air.

  Li Jinxin, a professor at the School of Electronic Information, Hangzhou Dianzi University, believes that amplifying everything requires energy, and stickers are "passive antennas" that cannot provide energy for effective signal amplification; in addition, the wavelength cannot be "stretched" in real life.
