Handover Handover is the transfer of an active connection or service session from one node, cell, beam, or coverage area to another. It supports continuity during movement or reallocation. Operations Hard Real-Time Constraint Hard Real-Time Constraint is a timing requirement that must be met every time because missing the deadline causes system failure or unsafe behavior. Operations High Availability High Availability is a design approach that aims to keep a system or service accessible and operational with minimal downtime through redundancy and failover patterns. Operations High Throughput Satellite High Throughput Satellite is a satellite system designed to deliver higher data capacity than traditional satellite systems, usually by using spot beams and frequency reuse to focus resources into smaller… Hardware Historian Database Historian Database is a time-series database or storage system used to record process values, alarms, events, and operational history over time. Software Holddown Timer Holddown Timer is a routing control mechanism that temporarily suppresses acceptance of route changes after a failure to reduce routing instability by holding a route in a suppressed state for… Operations Holdover Timing Holdover Timing is the ability of a system to continue providing acceptable timing when its external reference is temporarily unavailable. It maintains timing during reference loss. Operations Hub And Spoke Hub And Spoke is a topology or operating model in which multiple endpoints connect through a central hub rather than directly to each other. Concept/Framework Hub And Spoke Architecture Hub And Spoke Architecture is a network design in which endpoints connect through a central hub rather than directly to one another. It simplifies interconnection but centralizes dependency. Concept/Framework Hub Station Hub Station is a central satellite communications site that connects remote terminals to terrestrial networks and manages traffic in a hub-and-spoke architecture. It often hosts gateway and network control functions. Hardware
