Thanks to outdoor mapping in most parts of the world, you can easily travel from one place to another without the inconvenience of having to stop for directions or carrying paper maps with you. All you have to do is pull out your smartphone and the highly advanced mobile technology will allow you to get directions to your destination within the shortest time possible. However, GPS technology, even with all its high tech, becomes useless once you reach the entrance of the shopping mall, hospital, museum, hotel or even airports. GPS uses satellite signals to point out directions. On the other hand, the indoor positioning system does not rely on a single line of sight. There was, thus, the need to develop an indoor navigation system that would give directions to visitors who are not familiar with certain indoor environments.
