Close, the St. Petersburg number is true, but the location is not in St. Petersburg last night. Your options ...

Oh, I probably went to Joulupukki to visit the number plate: shock:: shock:: shock:

Do you understand that you are asking for, to put it mildly, not a legitimate service?

I want to find my own phone. Operators refused a similar service.
I lost him on the street or in a minibus. Beeps are on, I checked - no one called or wrote from him. That is, most likely no one found him.

Hello, Alena. What region are you from?

Under the "mobile" cap ...

The ability to determine the location of a mobile phone is provided by a GSM network device. The device is turned on ...

... periodically sends a signal to the beacons (or cells) of the mobile network, thus maintaining communication with them. If you know the exact location of the cells, it is possible with a relatively small error to determine the area in which the mobile phone is located. Sometimes the signal level can be used to calculate the location - this allows you to more clearly determine the distance between the phone and the lighthouse of the mobile network. The error in the accuracy of determining the location of the phone ranges from 100 to 200 meters. Whether this number is large or not is difficult to judge. Probably great, if we are talking about skyscrapers in a metropolis, and negligible if you need to find a person outside the city.

LBS technologies in many countries are considered as an inexpensive and convenient alternative to tools based on GPS satellite navigation systems, despite a number of rather significant drawbacks. Among them, first of all, the fact that the subscriber should be in the coverage area of the mobile operator, which is not always feasible. mobile phones Although today there are mobile navigation systems using information from GPS satellites. The accuracy of determining the coordinates of a mobile phone in this case is much higher - the error is not more than 10 meters, but for this, mobile phones must be equipped with special GPS receivers.

The task of positioning a subscriber location is possible in two implementations. The first is strictly navigational, its purpose is to find the geographic coordinates of the subscriber: latitude and longitude, or to uniquely determine the position on the ground. The second is determining the location of the user (district, region) without knowing the exact coordinates.

Locating a subscriber simultaneously has two aspects. The first is related to security considerations, for example, it may be necessary to search for the subscriber or the exact location of the person who contacted the rescue service. The second is purely commercial, aimed at providing the user with certain services, depending on their location. One of the most popular uses of LBS today is that people are helped to navigate in an unfamiliar place. Information of this kind can be provided to the subscriber in the form of a text message or a fragment of a card. If the phone has Internet access (via GPRS or WAP), this kind of information can be obtained through the website of a mobile operator or manufacturer of special geographic information systems. In Europe and America, LBS technology is used to control the independent movement of children.

In our country, LBS is taking its first steps. The dispatch system “UMC Navigator”, which is installed on vehicles, allows using a mobile phone to obtain information about the route of traffic.

Another solution in the field of LBS is the free online geographic information system "Navigator" (manufacturer - company "Visicom"). The peculiarity of this system is that the subscriber indicates his location independently with orientation to nearby objects, for example, a street or metro station. Based on this data, the system informs the subscriber about objects that are located in the subscriber’s area. There is also a navigation system on the country's roads. To work with the system, you need a mobile phone or PDA with Internet access and Pocket PC operating system.

Despite the obvious advantages of this technology, it found opponents who defended the human right to non-interference in personal life. In their view, determining the location of a person by mobile phone violates this right. A definite solution to this problem is the permission of the owner of the mobile phone to provide such information to third parties. For this, user authentication systems on the mobile operator’s website are used. But, of course, such information, regardless of the user's desire, may become available to representatives of special services or the police. If we are talking, for example, about terrorists or child abductors, we are not talking about moral aspects, and LBS-technologies can just solve such issues in this case.
