BERT (BlueSense Enhanced Real-time Trilateration) is an algorithm developed by us that is able to determine the position of devices with Wi-Fi or Bluetooth. Based on signal strength and time, our sensors continuously determine the distance from device to sensor. The device does not have to be connected to the Wi-Fi network. Measurements are communicated in real-time to the BlueSense platform. By combining these measurements, BERT calculates, in real-time, the position of the device. BERT is a smart algorithm and takes into account that people might have more than one device. Based on patterns, BERT learns which devices belong together and can deduct how many people are actually present.
We are able to use every modern Wi-Fi infrastructure in order to measure occupancy. Unfortunately, existing infrastructures are not always capable in providing desired accuracy. Therefore, we often employ our own sensors. Currently. our sensors are leveraging Wi-Fi and Bluetooth technology. BlueSense is working closely together with the market leader in IoT in the Netherlands in order to test new sensor technology. This enables us to use different kinds of sensors like CO2, pressure- or infrared sensors.

The BlueSense analytics platform
Our solutions and analytics are running on the Google Cloud Platform. This has a number of advantages:
1. Low cost and future proof.
Cloud services are much cheaper than traditional hosting services. This translates into the price of our services. Furthermore, the google Cloud Platform is highly advanced. This means that additional data sources can be added very easily. It also allows for leveraging the latest technological developments, for instance machine learning.
2. Easy implementation and robust.
Bu using a Cloud solution, local installation is a thing of the past. In order to use our services, simply launch our favourite webbrowser. Additionally, the Google Cloud Platform ensures you have 24/7 availability of information.
3. Safe and secure.
Traditionally, cloud solutions where used mainly to save money. Today, reliability and security are much more important drivers for using the cloud. All data and software used by BlueSense is located in the Google data center in Belgium. The Google security model ensures that everything is secure and safe. More information can be found here.
We employ 'Privacy-by-design' as principle. All relevant data are completely anonymised and can never be traced back to individuals. Furthermore, we do not store data any longer than required for our services. In practice this means that we do not store raw data for longer than one year. If desired, we can employ the services of a Thrusted Third Party to anonymise data irreversibly.
