Questions how to use beacons and app

How we can record live data from the students/ users in live time for data collection from a smartphone or iPhone device? following on - do the users need individual smartphones/ handsets to record this data or is there a solution for the data movement of the students/users to be collected and collated visually as a whole?

We also need to track movement of the equipment i.e. tables and chairs in the same space – so does each piece of equipment require an individual beacon to be attached to be logged and record data? or can the data for all individual pieces of equipment be recorded and collected as a whole from a data collection Bluetooth device of some sort to feedback into the visual representation?

With this been said, can all this potential data for students/ users and equipment be collected into one solution which can give back real time visuals and live information?
