Setting: 1999, USA
I have an FBI agent who receives a call from an untraceable (disposable) cell phone. I know a cell phone signal can be triangulated. What I need to know is whether a cell phone's position can be triangulated on an already terminated phone call. For example: Can my agent go to the cell phone service provider, give them the time of the phone call and phone number of the calling party, and look up in their data where the phone was when that particular call was made? The agent doesn't necessarily need to know the current location that can be gotten from 'pinging'.
I've looked thru the archives here, searched cell phone; triangulation; sigint; comint; cdr (call data records); LUDS; terminated call; etc, in various combinations.
Your help is appreciated.
ETA: thanks for the help!
Hey there, awesome people with all the answers! I am writing a series of short stories which take place in the Victorian era (in London, if it matters), specifically from the 1870s to 1890s.
I'd like to know what shaving cream was made out of then. Same stuff as today (and what is today's shaving cream made out of anyway? It smells nice...)? Or was it just soap lathered up good and fluffy with a brush?
Thanks in advance!
Googled: various types of phones, GPS, GPS tracking
Okay, this is for a storyline detail that I'm thinking about, and I'm afraid that I know jack-all about cell phones. If one were to pick up, say, a Diamond, BlackBerry or a Treo outfitted with a GPS system, could the phone's location actually be traced by a second party if they had the phone number? I *know* what the television thrillers show-- you can do it with a paperclip and a bit of reflective foil off a CD or similar, but we're not all of us MacGyver. Can this actually be done?
Thanks, y'all; I really appreciate it. If it can, it'll be a plot-point. If not, oh well, it was a nice idea. ^__^
DON'T DELETE STUFF.
Complicated version: Once you post a question to the community, the discussion belongs to the entire community, not just you. If you don't like the direction that the discussion is taking, too bad. It's not your choice where the discussion goes or when it ends.
I will ban people who delete their entries. And I will enjoy it, because it's one of my pet peeves.
This applies to comments as well. If you delete someone else's comment, with the exception of anonymous spam, you'll be banned. If someone is breaking the rules, contact a mod - or screen it, if absolutely necessary, and contact a mod. We need the evidence in order to ban the person or report them to LJ Abuse, if it's something truly serious. Don't delete your own comments because you regret them, either. If you made yourself look silly, suck it up.
(I know someone is going to ask about deleting & reposting right after a comment is made to make edits - so yes, that's fine, as long as you're not trying to cover up what you originally said. I can also see questions about deleting because you posted to the wrong community - yes, you can do that to, although if I didn't catch it while it was up I might ask you what happened.)
EDIT: And yes, if you delete your post, I will probably ask you what happened in the latest post of your journal - because that's the most sure way that's left to contact you, with your post gone. If you don't like it, don't delete.
If you're bitchy to me about bringing comm business into your journal after you delete a post, I'll ban you because you're being a stupid asshat, especially if you ban me because you can't handle being told not to break the rules again, omgwtfisyourproblem.
