Bluetooth beacons are based on low energy proximity sensing and can transmit specific information to mobile devices. They have been used in increasingly diverse settings and can be used as an indoor positioning and information system. They are now used for wayfinding which can help people with visual impairments or with other disabilities like anxiety. An Ottawa Public Library branch has launched this system and this Client is looking for a less expensive way to have a similar system in the main uOttawa library. https://biblioottawalibrary.ca/en/blogs/accessible-wayfinding-ottawa-public-library 
Your task is to design an accessible wayfinding system that will work in the uOttawa library and provide valuable information to all users of the library.
