In this introductory chapter, we have identified how location-based services work, the buzzwords behind all things location and the importance of GPS.

Specifically, we discovered location-based services and their applications in the real world, how Microsoft uses location in its Windows Phone 7.5 devices, and GPS and non-GPS based solutions for location. We also discussed new potential in LBS markets, that of indoor navigation.

Now that we've got our feet grounded in location, we can move to the next chapter that covers Windows Phone 7.5 Location Services!
