Abstract
The increasingly widespread use of sensor and actuator networks and in general of the Internet of Things (IoT) in several areas of precision, imposes upon localization systems that can often equip them with a robust and more precise localization. It is in this sense that UWB technology has proved to be one of the most powerful communication technologies for these localization systems; thanks, in particular to the bandwidth occupied instantaneously by the signal allowing a very fine temporal resolution. Constructors have set up localization kits based on various technologies. These kits facilitate in a way the work of localization of users. In this paper, we present results on the performance study of the Decawave PDoA Kit. This Kit uses the PDoA (Phase Difference of Arrival) to determine the Angle of Arrival (AoA) parameter with UWB technology. This study is in context of localization by AoA for an application to protect agricultural crops against grain-eating birds. The results of the study show overall AoA measurement errors around 10 degrees in an ideal environment.
Highlights
The location in communication systems has always been a technological challenge for researchers
We propose a study of the performances of a ultra-wideband standard IEEE 802.15.4-2011 (UWB) localization system based on the angle of arrival (AoA) of Decawave
We have studied the performance of the Phase Difference of Arrival (PDoA) Kit
Summary
The location in communication systems has always been a technological challenge for researchers. Dominated initially by the GPS system, we are increasingly seeing the implementation of precise and more energy-efficient indoor location systems This infatuation for localization is especially boosted by the event of wireless sensor networks and the Internet of Things (IoT). Location systems can be built around several technologies specially the UWB This UWB technology, thanks to its wide bandwidth, is one of the most widely used technologies for extracting location parameters such as Angle of Arrival (AoA) and more classical time of flight measurements [1]. It offers a precise location with margins of centimetric errors. We discuss measurement system operation and the last part will be devoted to the presentation and analysis of measurements
