GPS has been with us for many years, and this is what most consumers think about when they hear the term location-based services (LBS). While the satellite-based routing capability needed to help us get directions will remain an important capability for the foreseeable future, location-based services is morphing into something that is well beyond what the original creators envisioned.
Indeed, as we progress to a more autonomous world, the future will be driven by a required knowledge of location, both internally and externally to our immediate environment. This includes in-building and other enclosed spaces, something GPS is not capable of providing.
