Apple Will Be the King of Indoor Location Services

Without saying so, Apple has entered the battlefield of indoor location services. And it appears they are going to win – and win big.

Their first move was when they released the iPhone 4s with Bluetooth Low Energy (LE) support in it. Many observers have been expecting Apple to ship NFC support in their phones for a long time. Not only do they continue to disappoint in that area they instead shipped Bluetooth LE with little fanfare.

Their second move was the acquisition of WiFiSLAM in March of 2013. WiFiSLAM was a small startup company that was doing some amazing work marrying up machine learning with WiFi triangluation and raw sensor input from a mobile device's compass, inertial and gyrosopic sensors. Their work promised to dramatically improve the ability for a mobile device to determine its location indoors.

Then in June of 2013 Apple announced iOS7 and there was a little remarked feature buried in the slides - iBeacons. While official information about iBeacons from Apple is under NDA, some reverse engineering and a lot of speculation has revealed that iBeacons are a protocol enhancement to Bluetooth LE that enables devices that conform to the iBeacon protocol to integrate with iOS Core Location services. The result is that iOS applications are able to detect and respond to events that indicate that the device has moved into and out of a region defined by the iBeacon.

Finally, when Apple announced the iPhone 5s, there was an interesting new chip onboard the phone: the M7 coprocessor. This chip is "designed specifically to measure motion data from the accelerometer, gyroscope, and compass".

Individually, each of these moves seem relatively incremental until you put them altogether in this context:

  • Create inexpensive iBeacons that can be placed indoors that not only define a region but are registered at a particular location
  • Use Bluetooth LE in mobile devices to communicate with them without draining the battery
  • Pull high precision motion data from the M7 coprocessor, again without draining the battery
  • Integrate all of the above using WiFiSLAM's algorithms
  • Make it all simple to integrate into iOS applications.

The result is going to be an amazingly inexpensive, power efficient and simple to use and operate indoor location system. In typical fashion, Apple is addressing the entire ecosystem of the indoor location problem in a very innovative way – the result of which will again be significant market domination.
