Operational Interoperability The platform's mission + IERs
The various systems each platform has
System Interoperability
to support their mission.
Technical Interoperability Deals with message implementation
Generic term for a C2, Comms, and ISR
Gateways network node designed to provide inter-
operability connectivity and flexible.
Data forwarders Provide gateway functionality
Routers and Retransmitters Perform a function called cross-banding
When a communication node receives
signals on one frequency and simultane-
Cross-banding ously transmits on another for the pur-
pose of full duplex communication or sig-
nal relay.
