How the data is used

This section provides a brief overview of how the data provided to Location Awareness Services for WebSphere® Premises Server is used. Each item that is represented is described in greater detail in the sections that follow.

Data is used in Location Awareness Services for WebSphere Premises Server as follows (see Figure 1):
  1. A third-party event provider sends provider-specific data.

    Location Awareness Services for WebSphere Premises Server regularly receives data from the event providers, which usually are connected to a number of event devices (receivers). The receivers regularly receive signals from active tags that are usually attached to assets or carried by people. The event providers consolidate the signals that are received and create fixed-format messages that are generated from the signals. Each of these messages contains details about a single tag, including tag ID and current position.

  2. Location Awareness Services for WebSphere Premises Server recognizes the event and transforms it to a provider independent format that is used throughout the internal processing of Location Awareness Services for WebSphere Premises Server.
  3. The event is linked to a zone. Because zones can overlap, a location event can affect multiple zones.
  4. Rules are checked and, if necessary, an alert event is issued.
  5. The event is sent to the subscribing programs and notification programs. See Location Awareness Services for WebSphere Premises Server events for more information.
