Key Points Affects antenna gain and beamwidth Important in satellite and wireless link budgets Influences installation and pointing requirements Balances performance against physical constraints Larger dishes generally improve gain but increase physical and installation requirements Definition Dish Size is the…
Key Points Stores curated analytical data organized around known schemas Optimized for reporting and query performance Used in business intelligence and enterprise analytics Supports repeatable analytical workloads Requires ETL or ELT processes for data preparation Provides governance and data consistency…
Key Points Stores values with timestamps or ordered time context Supports history, trend analysis, and reporting Common in operational and monitoring systems Organized around time to enable efficient writes and chronological query patterns Used in monitoring systems, industrial historians, observability…
Key Points Arises from shared channel use Common in wireless and satellite systems Can reduce capacity and quality Managed through reuse planning and coordination Central concern in spectrum reuse and coordination Definition Co Channel Interference is interference that occurs when…
Key Points Reduces repeated network transfers Improves access during limited connectivity Supports software, media, documentation, and operational reference data Enables local reuse of data in bandwidth-constrained maritime environments Balances local performance against data freshness and storage capacity Definition Content Caching…
Key Points Operates above basic control loops Provides high-level process oversight Used in industrial systems and SCADA Focuses on supervision and coordination rather than direct regulation Coordinates operation without replacing local control loops Manages process state through high-level commands and…
Key Points Refers to the receive direction at the user side Used in wireless, satellite, and broadcast systems Pairs with uplink in bidirectional links Affects coverage and downlink capacity planning Performance determines how well users receive data, media, or service…
Key Points Supports transmission of surveillance data Extends sensor coverage or communications reach Used in security and monitoring operations Can be airborne, terrestrial, or network-based Bridges surveillance sources with monitoring destinations when direct connectivity is unavailable Definition Surveillance Relay is…
Key Points Measures separation between polarization channels Used in satellite and microwave systems Higher isolation reduces interference Important for polarization reuse Strong polarization isolation improves dual-polarized link usefulness and reduces cross-channel contamination Definition Polarization Isolation is the degree to which…
Key Points Connects industrial field devices to controllers and supervisory systems Used in automation and control systems Supports deterministic or structured communication Common in legacy and mixed industrial systems Often describes a family of industrial protocols rather than a single…
