For some users on Android, calling for help is going to be upgraded.
With the change, 999 operators (the emergency number in the UK and many other countries) will be able to access information from Android’s new Emergency Location Service. ELS makes up for tracking where with the help of GPS and cell towers can sometimes suffer: indoors. Google has a vague idea of how it works – it still uses GPS and cellular signals in addition to data about the location of applications, and Wi-Fi. It can also turn on the location service on the phone, if the user has them off.
The service will be available to 99 percent of Android devices (those with Android 2.3 and above). It will be supported by the main carriers of UK including EE, BT, Three, Vodafone and O2.
Typically, the operator will continue to ask the caller for their location, but the location, GPS is sent to them in any way. However, wireless devices have long been difficult than landlines – even with GPS location, it may be difficult to locate the caller inside a building, especially a large number of floors or if they are underground. There is a development technology that is designed to solve this problem called Inside Positioning System (IPS), but it is still under development, but is not perfect and not as widely used.
In the United States, the policy of the Federal Communications Commission is to leave a specified location tracking technology for each carrier. There are certain standards requiring devices to transmit their GPS location, but for more accurate information about the location of that GPS-could not be controlled (such as indoors on different floors, garages, etc.), the procedure may vary.
