Abstract: A method is disclosed as including sending, to a remote server, information identifying a first location within a building. In response to such sending, data may be received from the remote server. The data may comprise a plurality of unique identifiers, each unique identifier thereof corresponding to a unique radio tag located in a unique location within the building. The data may be used to deliver to a user a first series of audible commands guiding the user within the building toward the first location. For example, a first radio transmission may be received from a first radio tag located within the building. The first radio transmission may communicate a first identifier that is associated within the data to first navigation information. Thus, the first navigation information may be used to guide the user within the building toward the first location.
