• The solution's modularity enables it to be deployed in parts simply, without necessarily making
use of advanced processing and the capabilities of the Intelligence Layer.
• Unique Acquisition Layer, valid for different services.
• Independence of access technology and sensors. Compatibility of different access networks
and M2M protocols.
• Open protocol support, protocol translation, or other solutions are required to make the platform
independent of device complexity and allow access to sensors from different manufacturers.
• Ability to add new connectors when they are standardized.
• Access to platform sensors such as an event bus on which information from sensors and smart
devices is accessed through the transport network.

6.3.8.3.2 Knowledge Layer
The Knowledge Layer contains the elements of treatment, management and exploitation of
information, and is responsible for:
• Access to all historical and real-time information.
• Movement of data received from the acquisition layer, between the different functions of the
Knowledge Layer for storage, processing and retrieval, and towards the Interoperability Layer.
The data in this layer are already abstracted from the devices that generated them and must
be treatable following standard data models.
