People of GSM FORUM,

Does anyone have some schematics to build a GSM Jamming?!!

(My apoligises if this section isn't the right place to ask this kind of things!)

I apreciate help!<br />Thank for the atention!

For my University Degree Thesis, I built a universal GSM cellular jammer , that has a very low RF output. I have also written a 30,000 word thesis, detailing my complete design, schematics of transmitter, jammer, etc, if your still interested get in contact,

i will give circuit diagram of GSM&PCS JAMMER with local available spare parts its easy to make for this i required c45 repairer or solution for when i sw on phone blink light but not on. set is ok due to unloking this forum log file set is damaged.

Basically to build a good Jmmer you must have at least 5W power to override the Tower Signal. You must then amke a freq shifter from 900 Mhz up tp 1Gig. Shifting freq must me of 32Khz and changing spped of at least 40 Mhz (it should be fast enought).

@Duolabs: with 5W what distance can it dirt?

the most easy way is to take some broken mobile phone cut the part with power amplifier out make some simple oscilator for 950mhz (can take it fron some old phone also) and noise generator you will have simple jammer about 3W power.

it is easy to block tower but imosible to block phone, but that is not problem.

would like to inquire how a jammer is used and for what purpose is it applicable for ?

i just need clarification so i know if it has some use for me. thanks

mtlgr101 · 03-09-2004, 05:24

Hi,

I want to know what a jammer is useful for so i would understand if i would have some use for it.

Thanks

can be easily adapted to any frequency you require.
You can amplify the signal up to 50w if you want.
Depends on which amplifier module do you use.
For best results use hybrid module because they can withstand hi swr (jammers require high bandwidth)

But even this is complicated to build.
