RTLS POSITIONING SYSTEM ON IBEACON TECHNOLOGY
iBeacon beacons operate on Bluetooth Low Energy technology. Their working principle is very simple: iBeacon beacon sends the dataset (UUID, Major, Minor), and the receiver gets RSSI signal packets. The dependence of the RSSI signal level and distance to the iBeacon receiver is figuratively shown in the graph. But RSSI signal oscillations at a fixed location strongly affect positioning accuracy. Thus, they should be taken into account while developing RTLS solutions. Each developer of IPS (Indoor Positioning System) systems tries to invent its algorithm making positioning as accurate as possible (for example, using recursive filtering by Kalman algorithm and/or neural networks for the approximation of the results to determine the exact location). Merusoft uses high-accuracy positioning algorithms from the Finnish company Quuppa. It allows us to develop mobile applications and software solutions for RTLS with positioning accuracy from 1 cm to 1 m on the iBeacon technology and to compete with solutions based on the UWB technology, having won on price and technological capabilities.
Advantages of iBeacon Technology for Developing Indoor Positioning Applications:
As a matter of a fact these are different tasks, so they require a different but duplicate infrastructure on the iBeacon platform.
Merusoft Tracking unites these tasks. We select equipment and software algorithms of positioning systems that solve the client's tasks as efficiently as possible. In practice, some tasks arise when it is necessary to control the movement of employees with an accuracy of 1 meter in the production department, but such accuracy is not needed in the office space. In such cases, we recommend combining Quuppa's infrastructure with Minew's low-cost iBeacon gateways on the Merusoft Tracking platform to provide a cost-effective solution. The system is installed locally and does not require an Internet connection. If you wish, you can use cloud services. A special mobile SDK application emulates the workflow of iBeacon beacon for Quuppa locator.
IBeacon beacons for permanent installation are used for mobile applications. Mobile iBeacon beacons in form-factors: SKUD cards, the wristband, pendant on a neck is used for the control of movement and work in pair with an iBeacon Gateway. The Quuppa locator is paired with iBeacon equipment with firmware installed.
