Courtesy of Global Positioning System (GPS) technology, you can easily move into unfamiliar territories without the worry of getting lost or having to stop to ask for directions from strangers. More importantly, GPS has been influential in preventing the loss of lives through accidents as well as helping in search and rescue missions as well as in speeding up delivery of emergency medical assistance services. Simply put, the technology is rivaled only by the internet in its application in mankind’s activities. However, there is a single flaw: its application as an indoor positioning system is quite challenging, sometimes impossible. Remember, however, that the main reason behind the use of WiFi in indoor navigation is the reduction of the large error margin that would have been experienced with the use of GPS.
