The Problematics of Multi-Platform Indoor Positioning Systems
نویسندگان
چکیده
With the constant platform fragmentation in the global smartphone and tablet market, providing a multiplatform indoor positioning technology is and ever more complex task. RSSI-based hybrid indoor positioning technologies provide hope for a unified indoor positioning solution with-out the need for calibrating each and every device manually before use. But differing antenna construction, sensor designs and differences in software provide measurement readings that are challenging to compare and thus make the development of multi-platform indoor positioning solutions challenging. The different hardware and software platforms on a wide array of hard-ware provide massively differing measurement readings on a number of sensors essential for indoor positioning. Magnetometer, accelerometer and gyroscope readings from a multitude of devices are presented all measured from a custom-build software infrastructure designed to provide comparable readings on different platforms. Keywords— Indoor positioning, RSSI, Wi-Fi, Bluetooth, accelerometer, gyroscope, magnetometer, magnetic field sensor, signal strength, hybrid positioning systems.
