GRE Tunnel GRE Tunnel is a generic routing encapsulation tunnel that carries one network protocol inside another across an intermediate network by wrapping payload protocol in a GRE header. Protocol Greenfield Deployment Greenfield Deployment is the deployment of a new system in a new environment without needing to integrate with existing legacy infrastructure. Operations Ground Segment Ground Segment is the terrestrial portion of a satellite system, including earth stations, gateways, control infrastructure, and related facilities that form the ground side of the system. Hardware Ground Segment Architecture The terrestrial infrastructure layer of a satellite communication system, encompassing gateway and teleport sites terminating feeder links, tracking-telemetry-and-command facilities operating the satellite constellation, and network interconnection points linking the satellite… Concept/Framework GSMA The mobile network operator industry's global trade association, representing operator commercial and policy interests and coordinating cross-operator initiatives, working alongside technical standards bodies like 3GPP rather than performing their standardization… Regulatory & Compliance Handoff Management Handoff Management is the control and coordination of transferring active sessions or connections between access points, cells, beams, or other serving nodes while minimizing interruption. Operations 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 HAPS A stratospheric communications platform — an aircraft, airship, or balloon typically operating around 20km altitude — carrying a communications payload to provide wide-area ground coverage, recognized as one of the… Hardware 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 HARQ A link-layer error recovery mechanism combining forward error correction with automatic retransmission, in which a receiver retains and combines failed transmission attempts with subsequent retransmissions to improve decoding success beyond… Protocol
