12:55 Determine the location of the phone disconnected a myth? | |
| Reading the recently published topic, "How Facebook defended Tunisian Account" at the very end of the article drew attention to the case with Minsk. Reading the comments here, stumbled upon the assertion that you can listen to a disconnected telephone and different directions, including taking out the battery. As for the tracking unit is turned on - no doubt - is a LBS, and it should not be confused with A-GPS. Yes, and the MTS in 2009, was announced a service to locate. * Feature A-GPS With respect to this technology criticism does not arise, though, and should take into account some features of the LBS (publication on Mobile Review). * The general principle of the LBS * factor influencing the accuracy is Looking for and collecting information about the mobile tracking disabled, found an article on the site of "Komsomolskaya Pravda" (article dated 2006, ). Also interesting is the fact that a number of sites, this article is reproduced, republished, but the text is somewhat different, namely, in an article on the CP reduced information prowhisper and mestoobnaruzheniyu. In confirmation of the source 1 and source 2 refer to the source in the manual, which suggests the idea of ??amending the text of the article. Fact wiretaps disconnected the phone hence the news archive Ferra. A couple of years ago, answering the operators (at least for us) were given a different answer when phone is turned off ("subscriber not available") and the phone off the network (subscriber outside the coverage area ...»), but now the answer is the same and an experiment is not possible. It will be interesting to check whether the battery gets faster, while in the phone is switched off. However, the best test is to use special equipment to determine the "signs of life" unit. Therefore the question to habrasoobschestvu who have a view of the possibility of wiretapping and calculating the location of a disabled phone? UPD 1. Part of the issue raised at the Habre on "Anonymity in networks GSM».UPD 2. GSM standard requires that the device (On mode) periodically gives / receives the signal, because it is necessary to switch between cells.UPD 3. The battery is physically energized circuit. A button «power» - is not the first element in this thread, otherwise you would not show mode selection (for current models). This is far from «hard» power-off with the physical contact opening, and already in effect «soft» power-off.UPD 4. A modern phone (usually) - A powerful receiving-transmitting device, and can even work inside the pots, refrigerators, etc.UPD 5. At Mail.ru issue was raised and the view rashozhie (Example 1, Example 2). Unequivocal no exact answer.UPD 6. To Hack people also wrote that the phone can "ping", even off.UPD 7. Recommended reading information about the "Open an oscillating circuit. In theory, device may be in the "plays" the frequency and obtaining the specified command to issue low-power response.UPD 8. As mentioned in the comments, some phones are able to turn on themselves, on a command alarm installed software. It follows from this that the wiring and power management unit is not so easy arranged.UPD 9. To share Mobile-Review raised some technical aspect of feasibility.UPD 10.Farther into the forest - the more wood. On the question of the portal weapon DF off the tube is also open.UPD 11. As can be seen from many comments, a modified firmware allows you to do it. However, we are interested in phone "from the store." Hacking a server with firmware hack and fill rule, as this is just paranoia.UPD 12. RFID: a unique identification without batteries in miniature design (but only for a short distance). P.S. For those who place a minus. For you personally, I respect your point of view, but I'm absolutely indifferent rating topics and then released it to home or not. Question on the Internet is open and unambiguous answer to this question is no. Therefore, the topic was created on the resource, which is technically literate people who can express their opinions. We're not talking about whether it is done in practice spetsorganami, etc., we are now talking about the technical ability to do this (direction finding apparatus and periodically sending ping). | |
