Can you expand on the funding restriction ‘development and deployment of physical nodes’?

In data communication, a physical node is a node (an electronic device which creates, receives, and/or transmits information) which can be physically touched. General examples of a physical node include a modem, hub, bridge, switch, or data terminal equipment (DTE) such as a digital telephone handset or printer. In the context of the Exchange Network, physical nodes were devices that were installed, managed and operated by a state, Tribe, or territory participating in the Exchange Network to create, receive, and/or transmit environmental data. Specific EN examples include the physical node ‘OpenNode’ and, for Enfotech, a node that is part of their software suite. EN grant funds cannot be used towards the development and/or deployment of physical nodes.

A list of all unallowable costs can be found in the Section 2A(i) of Solicitation Notice.
