CrowdScan’s innovative solution only uses sensors or nodes, a central gateway to configure the wireless sensor network, low-energy radio waves and cloud servers where all the data is processed and visualized.
Imagine this: you want to measure a crowd in a busy shopping street. We will strategically position multiple battery powered sensors throughout the designated
area. We put the central gateway within reach of the sensors, in a radius of about 200 meters. This gateway not only configures the wireless sensor network,
but also sends results to the servers.
Then, each sensor emits a low power electromagnetic signal at a frequency of 868 MHz. If shoppers are present in the area, the other sensor receives this signal in a weakened form. Research has shown that this reduced signal due to the presence of people is linear with the number of people there.
Meaning: if a lot of people are present in the shopping street the signal will be severely reduced in comparison to the reference measurement (which will be executed when the area is empty).
After the measurements all the data are pushed into our analytics and algorithms to provide the right insights and predictions.
