With the popularity of Wi-Fi increasing dramatically over the last few years, so has the need and use of Real Time Location Systems (RTLS). The availability of WLAN Access Points (APs) deployed almost everywhere including universities, hotels and shopping centres to name but a few, allows RTLS to calculate one’s location using a number of different techniques and approaches. These approaches differ in terms of the measurement techniques used to sense and measure the position of the device. There are also a number of factors that influence the technique that RTLS choose to implement such as cost, accuracy, performance, and environment. The following section expands on some of the techniques used.
