Unauthorized Access The condition in which an individual, device, or system gains entry to a network, system, or resource without proper authentication or explicit permission, regardless of the specific technique used to… Concept/Framework Uncrewed Aircraft Systems The complete system encompassing an unmanned aircraft, its ground or remote control station, and the command-and-control link connecting them, spanning defense and civilian applications with connectivity requirements determined by mission… Concept/Framework Underground LTE A deployment pattern that adapts standard LTE cellular radio access technology — using ruggedized base stations and tunnel-appropriate infrastructure — for underground mine environments, delivering substantially higher bandwidth and lower… Concept/Framework Unmanned Surface Vessel Link Unmanned Surface Vessel Link is the communication link that connects an unmanned surface vessel with remote operators, networks, or support systems to enable command, telemetry, and operational data exchange. Hardware Unserved Area Identification Unserved Area Identification is the process of finding geographic areas that lack adequate communications coverage or service availability by comparing service availability, demand, geography, and measured performance data. Operations Uplink Uplink is the transmission path from a ground, local, or user endpoint toward a satellite, tower, or other receiving system, representing the outbound transmission direction. Protocol Uplink Power Control Uplink Power Control is the adjustment of transmit power in the uplink direction to maintain link quality, reduce interference, or comply with service requirements. Operations URLLC A 5G service category engineered to deliver extremely low latency and extremely high reliability, typically around 1 millisecond air-interface latency with 99.999% reliability, for applications where message timeliness and delivery… Concept/Framework User Link User Link is the communication path between a user terminal or endpoint and the network or satellite service it connects to. It provides end-user access to the service. Protocol User Terminal User Terminal is the end-user communication device or endpoint that connects a user or local site to a network or service. It is the user-facing endpoint of connectivity. Hardware
