How to make a battery powered GSM signal jammer for 2 m2 indoor use?

The wall area covered with wire mesh will reduce the strength of cellular communication. Depends on location. You can embed it in your wall... but copper. Put it on the side where the cell signal comes from. The effect of copper wire mesh is better.Even aluminum louvers can be used. And there is no battery power.

If you want a jammer... yes, you need... a jammer can be generated by RF modules of the same frequency group 1 meter away from the target phone. It needs to be loud and transmitted on all frequencies at the same time, or a very powerful single frequency in the middle of the band, with a very wide bandwidth, so that its spectrum can reach most of the used frequency hopping. This is accomplished by removing the Tx bandwidth control component on the jammer. Qiang I mean 100MW, because it will be very close to your mobile phone. Suppose the path to be taken is a single frequency transmitter that is turned on and off at 1 GHz. This allocates frequencies well.
But it may make it too complex, because this uniform propagation will indeed reduce the power output of any single frequency and require 1/4 watt. That is to say, data packets are sent in gsm jammer, so switching the whole jammer to 100 us per millisecond may stop data transmission. More suitable for batteries. Watch out for jammers that can interfere with your neighbors. If "frequency police" appears, it is said that this is a hobby experiment. You may not go to prison.
