Network Participation Groups (NPGs): Functional groupings of J-Series messages that support specific tactical functions (e.g., Surveillance, Air Control). Units participate in NPGs relevant to their mission.

Time Division Multiple Access (TDMA): The core principle of Link 16, allowing many users to share the network by allocating specific time slots for transmission, ensuring synchronized and deconflicted communication.
