abstract: The evolution of the technology in the wireless telecommunications industry drives the development of new applications for many di erent areas. Wireless networks provide the systems versatility in terms of installation, positioning and mobility. The ZigBee protocol implemented over the IEEE 802.15.4 standard and liability arising as the ZigBee Alliance, it's a protocol-oriented wireless communication typically de ned by low consumption and low bandwidth. This protocol can be used in a variety of applications, so it also can be used as a tool to implement a tracking system. This project aims to extend an 802.11 AP so it can include in the same physical equipment, besides the usual features, a ZigBee interface, which can be used for wireless communication. In addition to communication between Wi-Fi and Ethernet normally provided by an AP, it should be possible to link between ZigBee and Ethernet, and optionally between ZigBee and WiFi. To make this possible will be necessary to acquire, develop and integrate various components of hardware (processing modules, communication interfaces and physical interfaces) and software (device drivers and protocol stacks for communication). Based on this platform you can develop a system for compartment oriented localization. This platform also allows the possibility of developing protocols for more speci c localization. In this project it was developed the tracking system in question, which from the signal power received in the access point may determine whether a tag is in the range of the access point. The collection of information is done by issuing the information received by each access point to a central server, which collects and treats the data and subsequently displays the results in a Web interface.
