Abstract: GPS that is global positioning system is a very well-known and very old technology that we have been using for years. This technology has helped us from offices to our homes in our day to day lives. This technology is well efficient in detecting objects or people in our open surroundings but one drawbacks of global positioning system is that it is limited to outdoor systems. But as far as indoor systems are considered, GPS does not perform well. In this paper we will talk about a system that will work that is indoor positioning ips this can be understood as a GPS for indoor environment we will be discussing different technologies that can be used to implement it. Possible compatible technologies will be compared on various parameters such as cost, accuracy and availability of resources.General Terms: Sensors, Wi-Fi Access point, Pattern recognition Keywords: IPS - Indoor Positioning System, LAN - Local Area Network, GPS - Global Positioning System
