What is mobile phone positioning

mobile phone positioning refers to the location information (latitude and longitude coordinates) of mobile phones or end users through specific positioning technology, and marked the technology or service of the position of the positioning object on the electronic map.There are two types of positioning technology, one is based onGPS The positioning of the positioning is based on the base station of the mobile operation network.based on GPS The positioning method is to use the mobile phone GPS The positioning module sends its own location signal to the positioning background to achieve mobile phone positioning.The base station positioning uses the calculation distance of the base station's distance to determine the location of the mobile phone.The latter does not need a mobile phone to have GPS Positioning ability, but the accuracy depends to a large extent on the distribution and coverage of the base station, and the error will exceed one kilometer.The former has a higher positioning accuracy.Also use wifi Positioning in a small range.

The principle of mobile phone positioning

mobile phone positioning refers to through the wireless terminal(( cell phone Cure Coordinate with the wireless network to determine the actual location information of the mobile user (( Lepatinity coordinate data, including 3D data Cure ,pass SMS As well as MMS Voice is sent to users or provides some value -added services based on this.Positioning service is also called mobile location service (Location Based Service ,, LBS) , It is the network of telecommunications mobile operators (( like GSM net, CDMA net Cure Get the location information of mobile terminal users (( Latitude coordinates Cure With the support of the electronic map platform, it provides users with a value -added business for corresponding services.

mobile phone positioning is usedGSM The honeycomb technology of the mobile communication network to realize the location information query, GSM The wireless communication network is built from many communities like bee honeycomb. Each community has its own number. You can know the area where the mobile phone is located through the identification number of the mobile phone.At present, the positioning technology of mobile phone communities is still perfect, and the accuracy range in the urban area is roughly 200 About rice, the accuracy range of the suburbs is roughly 1000 rice ~ 2000 With around the rice, with the continuous development of the technology of mobile companies, I believe the accuracy will be further improved to further 50 Within rice.At the same time, the landmark name displayed at the same time is still optimized. As further optimization, the landmark will be more accurate.

Honeycomb positioning technology also belongs to the LBS base position positioning. This positioning method is commonly known as the ground positioning system because it relies on the signal tower distributed by the operator to obtain the latitude and longitude information to determine the position of the terminal.As long as all mobile phone cards are in the activation state, and can normally receive calls, they can be accurately located. Strong positioning capabilities, positioning signals can effectively penetrate the building, basement, and tunnel traffic.Each mobile phone card has the only identification code, just like a phone call, each number is the only point to the fixed mobile phone, the LBS base station positioning can also effectively find a fixed number through this recognition code to find a fixed number numberThe location of the mobile phone is presented to the electronic map. Such positioning technologies are compulsory and are widely used in some regulatory fields.

Features of mobile phone positioning

1 High coverage

On the one hand, the range of coverage is large enough.On the other hand, the scope of coverage includes indoor.Most of the time users use this function in the room, from high -rise buildings and underground facilities must be covered to each corner.According to the scope of the coverage rate, mobile phone positioning can be divided into three types of coverage services: the entire local network, covering some local networks, and providing roaming network services types.In addition to considering the coverage rate, the environmental factors of the network structure and dynamic changes may also make a telecommunications operator unable to guarantee services in local or roaming networks.

2 , Positioning accuracy

mobile phone positioning should provide different accuracy services according to the different user service needs, and can provide users with the right to select accuracy.For example, the United StatesFCC The positioning accuracy launched is 50 The probability within the rice is 67% , Positioning accuracy 150 The probability within the rice is 90% EssenceOn the one hand, the positioning accuracy is related to the positioning technology adopted, and it depends on the external environment of the business, including the radio communication environment, the density and geographical location of the base station, and the equipment used in positioning.

The role of mobile phone positioning

1. Parents position the elderly and children

It is mainly due to the needs of security and care. It is installed on the mobile phone of the elderly and children. Once lost, send a text message to get the specific map location of the elderly and children.

2 , Enterprise Management of Vehicle

GPS The signal is transmitted through satellite, restricted by the cloud layer and obscuration, there will be no signal in cloudy, basement, and tunnels to generate blind spots.Based on sim The positioning technology of the card is what we call the ground positioning -the enterprise effective LBS The positioning of the base station can effectively feedback the location information on the location on the ground. LBS The base station positioning saves the terminal cost, and the existing mobile terminal can be used directly, which saves the entire project cost. LBS Suitable for regulatory positioning requirements, and continuous positioning communication tariffs are relatively high.

3 The management of employees by enterprises

It can provide management for sales companies with multiple branches and work hours of sales staff. ; Mainly use base station positioning, which can be positioned with foreign duty employees to achieve mobile attendance, itinerary management, trajectory inquiry, visit management, etc., improve employee work efficiency, and reduce travel costs.

4 , Make remote decoding

The internal program where the opponent's number is located or fixed -line is bound to his number. After the binding, you can perform unlimited distance monitoring, interception, and positioning function.

What are the ways of mobile phone positioning

1. GPS position

Actually, I do nt need to say, everyone must know, first of allGPS Positioning, in general, the current mobile phone chip is supported GPS The positioning, that is, you don't want to support it, you can't be positioned.

2. WIFI position

Thenwifi Positioning, each wifi There is a unique one mac Address, when the mobile phone is turned on wifi At that time, it starts scanning and collecting surrounding routers wifi Signals, upload their location information to the server to form a huge hot spot position database.

This iswifi position.Although you can close it in theory, some you can't close it, because some software is like checking the household registration, you must support positioning to use.

3 , Base station positioning

There is also a positioning method, that is, the base station positioning, that is, the base station can locate your mobile phone through your mobile phone card.As long as your phone has a signal, others can track your position by checking which base station has contacted your phone.

In simple terms, at present, the approximate way of positioning is these.
