Where We're Headed: Using GPS, you can find your way in a major metropolis, suburbia or the middle of a forest. Several technologies, including RTLS (real-time locating system), can locate a person inside a mall, hospital, airport or office. Unlike GPS, which can't penetrate buildings, IPS installations require scattered fixed nodes on your smartphone that will provide your indoor position. While no IPS standards yet exist, the recently formed In-Location Alliance hopes to establish some sort of IPS direction.
Prediction: In five years, you won't need to locate a facility map to find out You Are Here. Instead, you'll use your phone to not only find where you are, but to get directions to where you need to go within a mall, megastore or otherwise intimidating building complex.
