The first step is to define the site to be analyzed, and to assign the architecture of the base stations used by the cellular telephone operators to it accordingly.
The basic idea is then simple: first you count the number of cellular telephones identified on standby on this predetermined site. This count is performed at various speeds, using various criteria (François Marchand - Alain Giaccone patent).
Obviously, the system used to process the data is entirely anonymous. It counts people present without identifying them.
Analyzing the counts related to these various parameters allows us - after a calibration period - to distinguish and monitor changes in the presence of the various population types, whether they are regulars, overnight tourists, day visitors or just passing through.
The real-time results can be provided as long as Info-Mobility can obtain non-personal, sequential extracts from the "visitor location recorder" database managed by the cellular telephone operators.
In this sense, the territory is placed under "attendance monitoring".
