This solution enables retailers to detect, analyse and act on location information from a wi-fi device, all using their existing wi-fi network. We use the information collected by the customer's existing infrastructure, in conjunction with information collected from Motorola Solutions' infrastructure, to detect customer proximity and calculate accurate location co-ordinates. We can then feed this information back into the customer's CRM system for the retailer to take action.
