Understanding the underlying technologies
For many applications, you need to know the exact location of a person or asset; for others, your needs can be satisfied by just knowing what room a person or asset is in. This kind of location reporting — in which location is reported as an abstract idea of where something is — is called symbolic locating. Room-level locating is a prime example of symbolic locating; location is reported in reference to the room that a person or asset is in or near.

Understanding the Methods of Locating at Room Level
You can use an RTLS to determine the room a person or asset is located in via a process called locating at room level. You can locate at room level in the following ways:
Using choke points: You can achieve room-level locating by creating choke points at the entrance and exit of every room. Using choke points ...
