A common implementation of network-based location-finding involves putting additional radio equipment on network base stations so that, in essence, they act something like a GPS receiver. Recording Equipment PSAPs record everything, including phone calls and all radio communications into and out of the center. ­In most basic 9-1-1 systems, you're looking at several pieces of equipment (besides the PSTN) t­hat play a crucial role in the process. The PSTN system routes 9-1-1 calls to the Public Safety Answering Point (PSAP) nearest to where the call originated. The mobile switch either forwards the call to the dedicated 9-1-1 switch (the same ones used by landline calls) for PSAP routing or routes the call itself to the nearest PSAP, depending on the routing path the wireless carrier chooses. It could end up at any PSAP in the remote vicinity, depending on how the individual wireless provider had set up 9-1-1 routing. The call has been routed to the PSAP nearest to that location or nearest to the cell antenna in use, depending on the particulars of the system. When your call reaches a cell phone antenna, the antenna sends not only your voice data and phone number, but also the latitude and longitude coordinates generated by the GPS receiver to the mobile switching station.


To learn more about the history of 9-1-1, see Why was 911 chosen as the emergency phone number? The PSAP call-taker (also called an operator or dispatcher) asks what the emergency is, what the location is and for a call-back phone number. That same month, a four-year-old boy helped save his mother's life when she started having an epileptic seizure, and a two-year-old beagle called for help when her person succumbed to a diabetic seizure - all by dialing nine, one and one on a telephone keypad (in the Beagle's case, she only pushed speed-dial number "9" and left the phone off the hook). The network uses your number to get your address from the ALI and uses your address to determine the proper PSAP destination from the MSAG (this is sometimes called selective routing, because the switch uses dynamic data to determine where to send your call instead of blindly routing it to a pre-determined PSAP). I sometimes get stopped when logging onto various websites I’ve used successfully before the VPN; I am asked for authentification and often am told my IP address is in the Washington DC area.

The system's creators choose "9-1-1" for a few of reasons: It's short, it's easy to remember and it was not yet assigned as an area code or any other telephone-related number. In one case, a teenager in Sweden hacked into a Southern Bell computer system in January 1996. There, he set up a computer code to generate multiple, simultaneous calls to 9-1-1 in a bunch of counties in Florida. It's possible to disable one of those, but at no time in history has a PSAP been "hacked" -- no one has ever gotten into the computers at a PSAP. These days most of the business professionals need to spend maximum of their time online and dealing with their clients located in different parts of the world, which will be possible only with good internet connection. In most cases, the recorded data is stored for a minimum of 30 days in the event that police, prosecutors, PSAP managers or call-takers need to review the information.

­There is no standardized method of implementing Phase II, so wireless providers, in conjunction with local public-safety agencies, are using various setups for providing cell-phone location information to PSAPs. Public-safety agencies report that wireless calls make up anywhere from 30 to 50 percent of 9-1-1 calls. The rise of both of these types of phone service has placed demands on the 9-1-1 system to adapt in order to maintain an effective public-safety network. Faster than e-mail, less intrusive than a phone call, it's a great way to ask quick questions, 인터넷 가입 현금 사은품 (mouse click the up coming webpage) share files and set up instant voice, Web or videoconferences. The data can include voice, video and computer data. You'll also want a second 5GHz band that the system can use as a dedicated backhaul connection for wireless transmissions between the main router and the satellites. WEP isn't as secure as other wireless security options. The phone lines in use when you dial 9-1-1 are sometimes dedicated lines and switches intended to provide some additional security from outages and congestion, but they're still just regular phone lines. Automatic Location Identification (ALI) The phone company has a subscriber database matching phone numbers to names and addresses.
