Proximity beacons for indoor location

Hi all,
I am wondering if there is a difference between the location beacons and the proximity beacons.

I am trying to implement indoor location (just entering/leaving a big room), but we have an order in place for proximity beacons. Initially thinking that we could just add proximity with the rule of if at least one beacon is in range then user in the room.

Is the correct approach for entering / leaving a “zone” by using the location beacons ?

Thank you,
