In the most Indoor Positioning Systems (IPS), users send a signal with a given wavelength to multiple receivers using a tag such as a beacon to identify the location. This method is very efficient to strictly figure out and control labors and vehicles in warehouse, factory and hospital. However, it is also required to only figure out routes of customers in supermarkets, which is very important to understand the behavior patterns of customers. However, it is quite cumbersome for all customers to move with tags upon entry. |
