APPARATUS AND METHOD FOR CALIBRATING A RADIO POSITIONING BASED POSITION FINDING DEVICE

摘要

The apparatus has comparing unit (51) that compares received radio signal pattern to reference radio signal patterns. Signal strength difference is determined between received and reference radio signal patterns, respectively, of selection subset. Received radio signal pattern is included with ID of receivable radio transmitter and signal strength of received signal. Comparing unit is provided to relate relative signal strengths for transmitter IDs within received signal pattern to corresponding relative signal strengths within reference signal pattern. Independent claims are included for the following: (1) position finding device for radio-based localization; and (2) method for calibrating position finding device based on radio-based localization.
