Abstract
This article describes the prototype of an 802.11b (wi-fi) wireless device that can determine the spatial direction from which every individual data packet has arrived, at a speed equal to the rate of wireless network traffic. Many problems in wireless networking stem from the fact that the users and their equipment are mobile; unlike devices attached to wired networks, their location is often unknown and difficult to determine. That makes traditional network management approaches ineffective. Integrating this radiolocation device with standard wireless equipment will improve the diagnostics and security management of wireless networks. Also, knowledge of the spatial direction of a source allows for an adaptive directional response specific to that source, providing foundation for better connectivity and a more rational usage of the wi-fi radio band.
