Implementing location based information/advertising for existing mobile phone users in indoor/urban environments

In the emerging world of m-commerce potential users consistently cite location based services as a technology they would be interested in using. However, solutions to obtaining the specific location of the user predominately rely on the provision of additional hardware and/or software within the mobile phone or the system infrastructure. These techniques are often inappropriate for indoor and highly urban environments where the line of sight to the location measurement unit is often unavailable resulting in inaccurate and unreliable positional information. In this paper we present a system that can be used with any current mobile phone system to provide location based information/advertisements to any mobile phone, equipped with Bluetooth technology, without any necessity of installing client side software. The system can be used to provide systems such as location based information for tourist in cities or museums or location based advertisements.
