In this paper, we propose a new m-commerce concept, m-Mall. Its users are walking individuals that shop in stores nearby, or interact with the stands in an exhibition. m-Mall servers know user location in real-time, by means of an auxiliary Bluetoothnet work, and push information into user handhelds, regardless of their technology. Networkside location allows the implementation of new services that cannot be supported by previous m-commerce solutions, where users were responsible of providing their position.
