University of Peloponnese (UoP) in cooperation with Be-Secure SME designed and developed a highly extendable, low-cost localization system focusing mainly on indoor environments. This version of the system relies on Bluetooth Low Energy (BLE) as wireless communication medium. The wearable objects use as reference the Received Signal Strength Indicator (RSSI) for the position estimation. BLE Indoor Localization System (IPS) can be installed with low deployment effort in a plethora of application domains and services. The results are very encouraging, showing that the system can reach up to 30~cm error of the final estimated positions compared to the actual/real position of people/objects. 

Objectives

Provide accurate position estimations Highly flexible and adaptable localization system APIs for applications to interact with and obtain location-related information

Challenges

Provide flexible localization services for aging people and tracking objects RSSI processing and filtering Extract movement patterns from users’/objects’ estimated positions

Technology

The implementation of BLE IPS is based on innovative technologies, combining data offloading techniques, distributed processing on edge and cloud components and finally an innovative position estimation processing chain. As base wireless communication technology, BLE IPS utilizes Bluetooth Low Energy.

Market

Applicable areas for BLE IPS are home assisted environments. More specifically, applications that monitor aging people and require the position of those people to react accordingly, can cooperate with BLE IPS to acquire this information.
