Each VLC transmitter is programmed to transmit a unique ID that is not visible to the human eye. Transmitted unique ID will be received as black and white stripes by rear camera of smart phone through a mobile App using Non-Line of Sight approach.
Decoding logic running in the mobile App processes the captured image and decodes the unique ID. Upon detection of the unique ID, mobile app will communicate with server via GSM/Wi-Fi to fetch the user position. Based on the received unique ID, the algorithm running in the server provides the exact position of user and the services associated with it. Mobile App after receiving the information from server displays the user location on a map and also pops the associated services.
