These guidelines arise in response to the potential negative impact that inappropriate handling of this technology could have on the privacy of natural persons.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Definition and uses of Wifi-tracking<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Wi &#8211; Fi tracking, also known as <\/span><b>Wi-Fi tracking technology<\/b><span style=\"font-weight: 400;\">, is a powerful tool that allows the <\/span><b>identification and tracking of mobile devices using the Wi-Fi signals they emit<\/b><span style=\"font-weight: 400;\">. Its main function is to detect the presence of devices in specific areas and analyze movement patterns, and it is used, among others, in estimating capacity, analyzing people flows and measuring dwell times.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Wi-Fi tracking is based on the detection of W-Fi signals emitted by mobile devices. Some practical applications include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Capacity estimation<\/b><span style=\"font-weight: 400;\">: Allows you to know how many people are in a specific place at a given time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>People flow analysis<\/b><span style=\"font-weight: 400;\">: Helps understand how people move within a given space.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Measuring dwell times<\/b><span style=\"font-weight: 400;\">: Allows you to evaluate how much time people spend in a specific location.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">This technology finds practical applications in a variety of environments, such as shopping malls, museums, workplaces, public spaces, public transportation and mass events. However, it is important to highlight that this practice carries significant privacy risks, as it can allow people&#8217;s movements to be tracked without their consent or knowledge, and therefore without an adequate legal basis.<\/span><\/p>\n<h2>What does it imply in data protection?<\/h2>\n<p><span style=\"font-weight: 400;\">Data protection authorities emphasize the importance of pointing out <\/span><b>the risks inherent in personal data processing that uses <\/b><span style=\"font-weight: 400;\">Wi -Fi Tracking technology.
