Hi everyone, i badly need help. I;m doing my final year project, that is a mobile jammer system. and i have no idea how to processed and there is no info on the internet too.. please if someone could help it will be of much help!!
Pleaaaaaaase!

IF you would explain what a "mobile jammer system" is, perhaps we could help.
Paul
well,the title i obtained is a mobile jammer system, that is it should prevent mobile phone from receiving signal for a radius of 100m
Delta_G:
That's not legal. And for good reason. Pick another project. We don't help people do illegal things here.
It's not legal in ANY country!

i cant, they have given me this title, and not willing to change it.
i have been trying to change the project but they are not willing to

Well, if they really are asking you to build a mobile phone jammer they will probably be guilty of aidding and abetting a crime .....................
Sure mobile phone jammers exist, and are used by the security forces, but they are developed under licence in special facilities.
I guess the OP sent a private message to everyone that responded.
And no! I will not help you construct one, but I will help in theory, if you can give a CLEAR reason to have an Arduino involved with the jammer.
Paul
I find it very difficult to believe that a college\university would ask students to build\design a mobile phone jammer.
Oh, I can believe it! Most assignments are thought up by assistants who are equally clueless.
Paul
There was a fun one that was published on Hackaday or something like that. The "(denial of) Service Dog". Basically a dog-backpack unit that can imitate nearby access points and capture any WiFi connection, sending it nowhere. I seem to remember there was an Arduino involved. I don't think it could jam cell signals.

I was going to explain to the OP that cell phone operations are in many different frequency bands and they are different for many countries. The requirement of a 100 meter radius means his jammer would have to be able to produce a rather powerful wide spectrum of white noise and if he has to ask on an Arduino forum, I am sure he is not capable, today, of doing such a project.
Paul
Following the principle of the DOS Dog, it seems that one method of jamming cellphones would be to act as a phony cell tower and accept connections from phones. Then just don't send any data to the phone. Masquerading as a tower for each cell company and every operating band of phone in the area could be expensive. Almost as expensive as a real cell tower, just with a shorter tower.
I've heard of some emergency services having equipment to do this. Basically they want to reserve cell communications for the emergency responders and not 10,000 gawkers posting photos to facebook. This is an even more complex requirement, only allowing some special phones to make connections.
The FAA looked into it to jam phones on airplanes, to prevent the phones jamming the avionics flying the plane. I believe the current solution is in the towers: once they work out that you are at airplane altitudes, they stop sending signals to you.
Yes the technology exists but unless you're already an engineer working for a cell company or a regulatory authority, I don't see any sensible reason for doing it.
Seems to me not a project an Arduino would be suited for.
Seems to me a friend bought one a few years back, maybe $50- range maybe 30 ft, used it on buses for a while when rude folks were talking loud on their phone. I think after the novelty wore off he put it away.
And at 100m range I would think it would fall into a tool for a terrorist category, in today's climate not a good place to be,

Quite possibly, but it may also be that the assignment, if indeed that is what it is, was thought up just in order to see which "final year" students are stupid enough to fall for it without thinking outside the box and questioning it.

Wouldn't that be a philosophy class or ethics class. Sounded like some type of engineering assignment.
Paul
An engineer with ethics isn't such a bad idea. Put it down to a well-rounded education. I well remember getting some assignment at uni and the girl who did best wrote a one-page treatise - "Why I shouldn't be answering this stupid question". I don't remember the assignment, but I will never forget the girl. Having said that, it wouldn't surprise me if this is just another bogus final year post. You see quite a lot of them.
[Leaving aside the ethics and legalities for a moment...]
(...and who knows, this project may be legal and even sop where the OP lives.)
Let's assume the OP is a final year student in a discipline that should have equipped him or her to undertake such a project, elec eng say, and not in something totally unrelated like dentistry. (A reasonable assumption, else it's a project irrelevant to the domain of study.)
I despair at the fact that an educational institution produces a final year student who throws his or her hands up in the air because the answer isn't nicely packaged on the internet, and says to a forum that they don't know where to start.
That pi$$es me (an engineer and father of two engineers) off more than the legal / ethical aspects tbh.
Go back to first principles, get to grips with the physics of the problem, then do some bloody engineering.

Indeed, but your best hope is that the educational institution actually doesn't, and the final year student is bogus. As I said above, there are a lot of them around, often with final papers due tomorrow, but with the literacy of a twelve-year-old. I guess it's a cultural thing - somewhere.

I wonder why the OP expects someone to believe that any instructor, in any educational system, would give a project like that to a individual who is so obviously and completely clueless.
