In this chapter, we learned about the amazing potential of iBeacons in home automation and also that beacons need not be fixed in the world. It's just possible for the beacon to be movable than the mobile user! Our tutorial showed us how to utilize background modes to range beacons in the background and also how to show local notifications when the app is in the background.

In the next chapter, we'll be discussing purchasing beacons from well-known manufacturers and their SDKs. We'll also be hacking Estimote beacons, which will require hardware beacons to complete the tutorial.
