Abstract

Proliferation of indoor sensor infrastructure has created a new niche for communications technology to exploit, yet research in this field has not produced a pervasive dynamic indoor location system which utilizes this latent resource. Studies employing either RFID or WiFi networks have produced a plethora of applications, but most are presented with a paucity of effectiveness evaluation within the context of utilized radio technologies. Therefore, after exploring a realistic 3-D radio propagation model to approximate radio propagation in indoor environments, we conducted signal strength measurements of both RFID and WiFi in a two-story building and studied the effectiveness of both radio technologies in indoor wireless applications.
