Cell phone jammers can replace Faraday cages?

    Hello, everyone
    Our school planned to build a large Faraday cage, but it was very expensive. I've seen on the Internet that cell phone jammers do the same thing, and they're much cheaper. Does that mean the device can replace the Faraday cage?

    Hello Sebastiane
    Generally speaking, it is feasible. Faraday cages work by isolating signals with a special material.  Thus, the transmission rate of mobile phone signal is low until the mobile phone signal is completely unable to transmit. And cell phone jammer, it is by the method of signal suppression to achieve the goal of signal can't transfer.
