iOS 8 uses motion sensors and M7 coprocessor for geopositioning inside buildings



According to 9to5Mac, iOS 8 in the further development of the software interface was CoreLocation, responsible for ge0location. The new operating system allows a more precise positioning indoors. Earlier CoreLocation interacted only with a cellular module, GPS and Wi-Fi. Now, it can determine the exact coordinates of the mobile device,  use the M7 coprocessor and built-in iPhone motion sensors.


The mechanism provides the ability to detect the location of a person inside a building based on movement. It works as follows: first mobile defines “area of ​​presence” by data from access points; Wi-Fi and GPS, and then analyzes the signal level and the wireless network architecture of the building to calculate more accurate coordinates. After that, the iOS 8 disables the GPS to save battery power and continues to rely solely on Wi-Fi and sensors on the smartphone. It is recommended to have the iPhone unlocked.

Developers already updated available CoreLocation. In the future, this technology will increase the capacity Apple maps application App by showing cafes, shops and individual departments and ATMs  locations when in shopping centers, as well as the gates in airports for instance. The feature is clearly not redundant, given the huge size and complexity of some infrastructure available around.


Apple long ago started to show their interest in geolocation technology: last year, the company acquired indoor location startup WiFi SLAM, working in this direction, as well as providing iBeacon, a service that helps you locate inside buildings using Bluetooth-transmitters.
