Scientists have made your life easier by developing an indoor Positioning System which will provide help in finding your way around airports or shopping malls. The indoor positioning system which has been developed for the cellular phones is similar to the GPS.
The Global Positioning System does not work inside the buildings as the satellite signals which have been used by the GPS do not have the ability for getting through the walls.
But, in the indoor positioning system, instead of the satellites, the cell phones can use the nearby Wi - FI transmitters. The signals from this are triangulated by the indoor positioning system for calculating the position, which is then displayed on the map. This was reported by the “New Scientist”.
The newly developed system is put in use in Finland for testing purposes. Even though this is not the first indoor positioning system, the others which have been discovered earlier have used for very specialised needs like helping the fire fighters for finding the colleagues during a fire accident.
The indoor position system which has been discovered by now owes its discovery to the world’s topmost cell phone manufacturer, Nokia. This feature can nbe incorporated with the current Nokia handsets.
One basic requirement for this system to work is the accessing of the maps which are located inside the buildings. This will be feasible only in public buildings where the site maps are already available.
If the current testing is successful, then the system will be rolled out earlier.
