We have presented the issues and proposed system for design and architecture of our own innovative work about the Location Based System for Mobile Devices based on integration of RFID and wireless technology.Wireless technologies are capable of supporting mobility for users,and thus are popularly adopted to access the Internet today.As long as the position of a user is identified,location-based services,such as tour guide systems and mobile shopping, can be delivered to the user and improve the convenience in life.In indoor environment, the GPS signal cannot be received,and the positioning service requires the aid of indoor wireless technologies,such as wireless LAN,Bluetooth,Infrared and RFID. By integrating these heterogeneous wireless technologies, a hierarchical architecture for the indoor positioning service is proposed to enhance the positioning accuracy. The function of our system is based on strategically located passive RFID tags placed on objects around building which are identified using an RFID reader attached to a mobile device.The mobile device reads the RFID tag and through the wireless network, sends the request to the server.The server resolves the request and sends the desired location-based information back to the mobile device. We had addressed that we can go through the RFID technology for indoor which provides us better location accuracy because of no contact between the tag and the reader and the system requires no line of sight.In this paper we had also focused on the issues of RFID technologies i.e.Non-line-of-sight & High inventory speeds.
