Can the jammer that blocks mobile phone signals penetrate walls?

Can a cell phone signal jammer penetrate a wall?

Many people are asking whether a cell phone jammer can penetrate a wall, and this question requires several factors to be considered.

First, let’s look at the jammer itself. The function of the jammer is to emit a special radio frequency signal to interfere with the cell phone signal, but when the signal encounters an obstacle on the transmission path, the signal will be attenuated, and the degree of attenuation depends on the nature of the obstacle. Solid walls of reinforced concrete or brick-concrete structure, as well as reinforced concrete walls and continuous brick-concrete walls, generally attenuate the shielded cell phone signal to the point where it cannot be effectively shielded. Since the signal is wireless and not X-ray, it cannot penetrate the wall directly, but refracts and reflects when it encounters the wall.

In some cases, different wall materials also attenuate the shielded cell phone signal to different degrees. For example, a wall made of light steel keel and gypsum board may have the least attenuation, while materials such as glass or wooden doors may also result in lower attenuation levels. In addition, if the cell phone signal is blocked, it may still have a certain impact on the other side of the wall through open spaces such as doors and windows or through reflection and refraction, thus creating the illusion of penetration ability.

In summary, while cell phone signal blockers generally cannot penetrate walls, their effectiveness can be affected by the type of wall material as well as openings or reflective surfaces that may affect signal propagation.
