This is a big topic, there are a number of technologies that are evolving to address indoor location/tracking, but they all have their own unique properties. Bluetooth is adding features such as time-of-flight and HADM (now called channel sounding). Those are worth reading up on. Also Ultra Wide Band (UWB) is another technology targeting location/tracking applications. Cost, power, range, accuracy and infrastructure requirements are all factors to consider.
