Different positioning services

When it comes to location tracking technology or positioning, you can easily think of GPS. However, if you drive GPS for a long time, the battery will be abused-it may be okay for an hour or two, but if you want to drive an app for location tracking for a day, it will soon be sucked up even with a mobile power supply. When there is demand, there will naturally be a market. To solve this problem, LBS came into being.

 

LBs is a location-based service. It obtains the location information of mobile terminal users through the radio communication network of Telecom mobile operators or external positioning methods (such as GPS, A value-added service that provides corresponding services with the support of the geographic information system platform.

 

Is to add other data connections outside of GPS to determine the user's location: WiFi signal, communication base station signal and user-set GEO fence. It will first check whether you are in the configured geo-fencing. Once you confirm that the user is in the geo-fencing area, the app will ensure that the GPS is not enabled. Similarly, if you are in a few known locations, such as working or at home, the app will turn off GPS and listen to signals that indicate you are moving. When the user moves the location, the app will re-open the GPS.

 

Currently, the number of mobile phones with GPS enabled worldwide has exceeded 0.77 billion. It is undeniable that location data is everywhere in mobile space. Location-Based Services on mobile terminals have also gone through a single exploration for individual users (such as foursuqare in foreign countries, Momo in China, and many apps from weather to travel ), many data mining services for enterprise users have also begun to grow.

 

In this way, services based on positioning services and big data bring a brand new blueprint for our daily life, which will inevitably cover all aspects of our daily life.
