Mobile phone number was positioned first must not panic, if indeed encountered personal property security problems to immediately find the police uncle. The phone to lift the positioning is actually particularly simple, just need to close the positioning service in the drop-down menu or positioning service can be. You can also turn off your cell phone's WiFi and data traffic to prevent the transmission of location data to achieve the purpose of lifting the location.
If you're still worried about being targeted by your carrier's base station, you can choose Airplane Mode or power off your phone, in which case any location on your phone won't work.
In some special cases, you can't turn off your phone's location services, such as navigating in some remote places with your phone's map, or for example, in a movie where a bomb explodes when you leave a defined area by locating it on your phone.
If you want to use your cell phone map to navigate, but you don't want to be located by others, and you don't have time to look at the location of the person who is locating the location through that software, you can open the phone's location permissions to allow only the map to use location services, and all other APPs are set to disable location services. How does the cell phone locate? Base Station PositioningBase Station Positioning is to determine the approximate location of the cell phone by the distance from the cell phone to the base station, and the precise location information of the cell phone can be determined by the distance from the cell phone to 3 base stations. Base station positioning is one of the earliest means used to locate the cell phone, because the earliest cell phone is not the function of positioning, that is, the 3-corner positioning method in the police film on TV.
The location of the base station will not change, and each base station has a satellite positioning module, through the satellite to timing and positioning of the base station. The location of each base station, want to determine the location of the phone through the base station is not a matter of minutes. But the base station positioning also has great shortcomings, such as there is no base station nearby, the base station signal is blocked or there is only one base station, the location of the positioning information will have a great error. Navigation Satellite Positioning Satellite positioning is based on the triangulation method to determine the three-dimensional coordinates of a point in space. As long as 3 satellites can realize positioning, 4 satellites can realize accurate positioning.
Each navigation satellite continuously transmits time information, precise orbital information, and so on. The satellite receiver calculates the distance (speed of light x time) of each satellite by measuring the transmission time taken for the signal to travel from the satellite to the receiver, and then determines the user's position based on the distance and position of the other satellites. The map software can then display information such as direction and speed by changes in the user's position.
The 4th satellite is used to correct the time difference of the receiver, as the great speed of light can cause huge errors in a very short time difference of the satellite signal. (Speed of light = 299792458m/s) WiFi positioning satellite positioning is difficult to solve some positioning problems in indoor environments, while WiFi exists in most indoor environments such as homes, hotels, cafes, airports, shopping malls, etc., which makes WiFi one of the most compelling wireless technologies in the field of positioning.WiFi's signals are not designed for positioning, which makes traditional range measurement methods based on arrival time/length of arrival are difficult to realize, as are methods based on the angle of the arrival signal. Therefore, in recent years, the main direction of research has been location fingerprinting methods.
The geographic area is covered by a rectangular grid, and at each grid point, the average "received signal strength" from each AP is obtained by sampling data over a period of time. The data is collected over a period of time, typically 5-15 minutes, and the mobile devices may be oriented and angled differently at the time of collection, resulting in a fingerprint library that can be compared to determine the location of the accessed device.WiFi location fingerprinting has been shown to be a viable solution for indoor pinpointing, but the ultimate solution will likely be a fusion of multiple positioning technologies, possibly using near-field communication, Bluetooth signals as additional parameters to improve positioning accuracy. To summarize the "era of big data", every time we install an APP, we will be reminded to obtain location information, address book, SMS, etc. However, the vast majority of APPs obtaining such information is not necessary, and only for the following three purposes: 1) To understand the user more y. 2) To sell the user's information. 3) To recommend the user's local contents and advertisements. Therefore, when installing an APP, you should be careful to turn on the privacy privileges such as location information, address book, SMS, and so on.
There is no need to panic when it comes to the location of a cell phone. At present, only carriers and public security systems are able to use the base station triangulation method to accurately determine the location of a cell phone (and do not need to use the cell phone network). The phone through the satellite positioning, WIFI positioning, base station positioning need to use the network to transmit the positioning information, others can get your location information, so the network is disconnected as well as the use of offline maps for navigation and positioning. If you really don't know how to do it, you can turn off the power of the phone or use flight mode, so that all the positioning based on the phone will be invalid.
