This work presents a user position management system for Wi-Fi networks. The location system is based on access point coverage range and beacon devices. The implementation was made over an authentication system, that was extended to manage SNMP (Simple Network Management Protocol) in order to handle, and SLP (Service Location Protocol) in order to provide and collect service usage information per user. Position management is an important topic on wireless networks research. The knowledge of a person location in a given instant is very useful to generate statistical information about the network usage. For example, it can be used to allocate resources to visitors which will tour a place according to their movement through the wireless network. Thus, it is possible to know how often a user requests a service or in which places he uses to be. Keywords Location management, wireless networks, ubiquitous computing, context awareness.
