Champions League Indoor Positioning

When it comes to indoor positioning there might be no harder task to master than the tracking of fast moving assets in steely environments. Especially when the assets consist of more than 70 percent water. Like people.

This is why bluetooth is ideal for indoor positioning:

Indoors, positioning with the use of BLE infrastructures has proven successful. However, this technology also has to meet special challenges depending on the architecture. Bluetooth is a high-frequency radio technology.  It is affected by the strength of the walls and what material the walls are made of. While, for example, wood causes only low absorption, water and metal and also people have very high absorption qualities. This is due to the high water content of a body (over 70%) and the resonance frequency of the water, which is around 2.4 GHz, the frequency at which many wireless local networks are operated.

In particular, steel construction methods constantly challenge inexperienced planners. Steel not only attenuates, but also reflects the signals and can thus additionally falsify the accuracy of the position determination.

Also when you track children on a ship, you want their position displayed NOW. You do not want to know where your child was. But where it is. For this reason, the system must be extremely stable and the latency extremely short. The position calculation must be done locally and not on a server onshore which is only accessible via an extremely expensive and more or less stable satellite connection.

Favendo specializes in indoor positioning and mobile tracking and navigation solutions as well as infrastructure development in extremely complex environments. Favendo focuses on on-prem solutions for highest data security. The core of every service is the most accurate possible localisation of objects or people indoors.

Favendo CEO Arnaud Becuwe: “Our aim is to guarantee our customers stable infrastructures and autonomous RTLS even under the most complex conditions, such as on the high seas. We not only track assets but also fast moving people, such as children on ships.”

Favendo provides an outstanding person tracking feature within it’s Commander SDK that masters all of the above mentioned challenges AND which is in daily use on six cruise ships with over 30.000 daily concurrent app users.

Indoor Positioning for industrial use cases

Especially in industrial applications a very precise indoor positioning can be necessary. In a production hall, small assets must be identified reliably, just as it may be necessary to identify assets of any size that are stored close together. In such cases, it is recommended to use a different positioning method than in the previously mentioned applications. However, the technological basis remains Bluetooth Low Energy even in cases where a very high granularity is required.  Favendo can calculate positions using the RSSI method (Received Signal Strength Indicator) and the AoA method (Angle of Arrival), which includes the angle of the signal in the calculation of indoor positioning and is therefore much more accurate.

The installation of the AoA hardware is also more complex, however, and the hardware is slightly more expensive. The cost, though, is still far below what would be necessary for a UWB system.

Decision making guidelines for the choice of an Indoor Positioning System

In order to decide which method and which system of positioning is required, interested parties have to keep in mind which granularity they need and how often. For some applications, for example, it is only of interest whether an asset – a machine or a goods carrier – is even present in the building or on the site. In this case we speak of “presence”. This can be tracked as often as required, but often it is only necessary to check the “presence” once or twice a day. If it is also important to know where in the building or on the site the asset is located, we speak of “zone” level. If the customer wants a continuous tracking of the asset, we speak of “positioning”.

Depending on the factors accuracy of the position, frequency of position verification, indoor/outdoor positioning, we at Favendo develop your indoor positioning from different technical modules, so that in the end a tailor-made solution is provided.
