war-chalking is different


war-chalking is writing with chalk the type of network, WEP key, and bandwidth for people who want to use it.




i used to read a lot of this stuff about 2 years ago... when it only started coming out... even 802.11b was the newest thing in the market and the g standard was only being planned... and now it's like everywhere... technology...


besides, afaik, most that you can do with a city-wide wireless network is simply break into it and steal bandwidth, you can't really do anything to other users. but i might be wrong.

Too bad its incredibly unsecure. All you need to tap into it is a pringles can and $10 worth of shit from radio shack (I'm not kidding)

exactly! high speed internet for freeeeee bro!

supposedly it does kill the emergency frequencies. it also kills the whole ham radio band, i guess that would be shortwave.

i haven't read through the link, but here it is
http://www.arrl.org/tis/info/HTML/plc/
it's the amateur ham radio website.

on another note, everybody could have internet/broadband. some places are just not feasible to the telco/cable co to go out and run a line. if they're not going to make more money then what it costs them to put the line out to say a rural area, they ain't gonna do it.

they should just keep with fiber and actually get that going and figure out how to solve the 'last mile' problem. it may be expensive, but damn it's fast.
hell, there's already people switching to gigbit, even some mobo's come with it built in.

here's a link to a quicktime vid that shows what happens to shortwave radio frequencies when there's bpl around.

i'm don't know anything about ham radio so anyhoo, i hope it works

you dont send data, you send pulses. modem makes data out of those pulses

unsecure indeed and I really doubt the realibility too... Think about all the hydro bump you can get in a day, lights flickering and all... isolated residences would prolly have some issues with that

And about the magnetic field, the equipment these days is reliable enough to isolate and shield the electric current from another... and I'm sure they found a way to counter that anyway since the project seems to be seriously considered..

Think of all the porn!!!!!

Ahh ok modulate/demodulate would make more sense. Still though, if it gets near a powerful enough electomagnetic field it would get scrambled. There were other issues with this too, dating back to when it was first thought up in the 70s.

depending on the system, electromagnetic fields act as signal rectifiers in most electric circuits. usually offestting the waveform by some regular interval in radiens ie pi, pi/4 etc. magnetic and electric fields rarely "scramble" electric signals, they merely offset them. w hich is why they play havoc on tv sets since they will cause pictures ot overlap and look all fucked up..(ever tried watching one of those illegal porn channels.....) if you want more info check out any upper year electrical engineering text book from your library or local colledge or whatever...
