I know that bombs can be exploded or triggered with handphones. But is it also possible to trigger a bomb using a laptop with built-in WI-Fi?

Sure why not. It'd be easier then with a cell phone.

Of course. You can transfer a "blow up" request with WiFi and you can send a "blow up" control signal with a laptop. I am missing something?

An interesting question. Homeland security will probably be visiting you soon!

[crycleascentyv]

But why would you want to use a laptop though? Price wise it would just be cheaper to to just buy a pair of those cheap pre-paid cellphones that cost like $25-35 a piece. Unless you could get some stand alone wireless device though, with some added circuitry. Yea, i think of crap like this all the time, even though i'd never do any of it. Much like how i scope out security where ever i go somewhere, just seems to be a habit of mine to think of thist stuff.

wat?

why are you asking this question?

[Marlboro-oroblraM]

lol @ question

[NerbuitW]

Want to know for sure? Here, just hold onto my laptop for a minute. I'll be right back....

[offemyJuccete]

wat?

why are you asking this question?

maybes hes been watching ultimate force ? lol some guy in afghanistan was going to set of 8 bombs at the same time with a laptop before the sas pwned him. (fictional tv series)

[pIp83Uns]

im quite sure it could be done. if the reciever on the device was programmed to a particular freq. sent form another device/location. hell this day and age, anything is possible

[appletango]

Well, the answer is, it depends.

WiFi, assuming the most recent 802.11g protocol is used, only has a maximum outdoor range of about 140m, and that is assuming line of sight is maintained. Therefore the bomb must be in very close proximity to the transmitter (presumably built into the laptop) for data to be sent.

A mobile phone on the other hand operates over exsisting infrastructure that can propogate a data signal to almost anywhere in the world, therefore range is usually not an issue. Even if no infranstructure existed, signals from a mobile phone can travel several km.

So, to answer your question, yes, you can, but you'll probably be blown up along with it

If you are using directional antennas, you can increase that range to miles. You still of course need clear LOS, but it's possible. Definitely not practical, either for distance or cost though. Wouldn't be very inconspicuous either with a 6 ft yagi sticking out in public.

I'm not from the United States. So, it'll be Interpol which will be after me.

As for those who asked why I'm asking this question, I've read a chapter in the manga 'Case Closed' in which Jimmy Kudo was trying to find a bomb on a Shinkansen train. He narrowed down the search to 3 people - an elderly man with a casette player, a middle-aged woman with a mobile phone and a middle-aged man with a laptop computer.

He zeroed in on the woman with the handphone but at the same time, I was wondering if the laptop could be used to trigger a bomb via wireless signals.

So, the comic doesn't specifically say "WiFi"? Assuming the bombers are not on the train that the bomb is on, then either the phone or the Laptop could have been used. WiFi is out of the question as there's no way the signals can reach the bomb on the train. However, you can get GSM modems for laptops that could be used in the same way as the phone.

If I had limited time and had to choose only one person, the safest bet would be the phone user, however, the laptop user should not be ruled out completely.

Edit: besides, who's to know that all three of them don't have mobile phones on them?

[Mugflefusysef]

actually wifi can be used over miles , it all depends on how much power you pump through the aerial and the size of it

Well then you'd need hacked/modified equipment as standard hardware must comply to regulations on maximum transmission power levels and antenna gains for the various 802.11 standards.

not really - just buy a high gain aerial

with say a nice 6watt booster running to it

[vosteglog]

if it can transmit or just receive something... I'm sure you can make it trigger any bomb.

Not rocket science really.

Problem is, that both the "b" and "g" Wi-Fi specifications are on two main frequencies, 2.4Ghz & 5Ghz, with depending where you live in the world, either channel 1-11 (europe), 1-13 (USA) & 1-14 (Japan), So your bomb reciever/detonator and Transciever is gonna have to be on one of those two WiFi Frequencies and on a certain channel which I'm guessing is 2.5Ghz - 2.61Ghz etc.

So the chances of someone else not using the same WiFi signal as you when you try and detonate your bomb, could be fairly slim, depending on where you are planning to set off your device.

The terrorists who stuck that Mercedes packed with propane bottles outside that nightclub in London planned to set off their bomb via mobile phone, but a fault stopped the bottles exploding and thus averted a serious disaster.

WiFi IMO is not safe enough to use as a a way of detonating a bomb, as the chances of someone walking past and detonating it themselves is too great, especially in this age of mobile phones, PDA's and laptops all with WiFi capabilities.

Typically terrorists & Criminals are fairly stupid and usually screw up something and then either kill themselves or fail to detonate their devices.

Which brings me to the subject of maybe one of the stupidest terrorists of all time, probably a member of the Darwin Awards.
Apparently this guy a member of the IRA, during the 80's, was driving his Transit van that inside had several hundred pounds of Fertiliser bomb, intending to blow up a RUC police station, when he decided to use an RPG to shoot at some soldiers prior to parking the bomb and detonating it, Unfortunately such was this guys stupidity, that he forgot about the backdraft from the RPG and subsequently blew himself and his van to hell and back.

Not the sharpest tool in the box. [rofl]

Reminds me of the story of the terrorists who had a carbomb that detonated one hour early because where the bomb & trigger was built didn't take into effect daylight savings time lol.
