SubPos Positioning System – A “dataless” Wi-Fi positioning system that can be used anywhere GPS can’t.
SubPos is an indoor positioning system that can be used in various environments such as metro lines, shopping malls, carparks, art galleries or even conference centers; essentially anywhere GPS doesn’t penetrate. It could also be integrated into an array of IoT enabled devices, from access points to Wi-Fi enabled light-bulbs.
When the world’s lifeforms are forced into subterranean dwellings due to nuclear fallout, evolution into lizard people or warming of the Earth, we will require a simple method for determining our position underground. In our current age, we are still working out the intricacies associated with determining our location in areas where GPS cannot reach
