Practical verification of radio communication parameters for object localization module

Abstract

The paper presents parameters verification of a mobile device (battery supplied) for object localization built with GPS module and radio front-end. At first, construction of PC device (stationary unit) and mobile device (unit) are described. Mobile unit may be attached to a movable object. More, objects in-motion requires short round-trip-time (mobile response on stationary request) and communication distance must be long enough for communication. In the paper the most important datasheet parameters have been compared with devices constructed and the number of test scenarios have been performed in order to verify parameters in real environment i. e. mobile unit lifetime on battery, communication range, output power, positioning accuracy, etc.
