UDP A connectionless transport protocol that sends discrete data packets without establishing a session, confirming delivery, or guaranteeing order, trading TCP's reliability guarantees for minimal overhead and lower latency. Protocol Ultra-Wideband A short-range radio technology that transmits very short pulses spread across a wide slice of spectrum, enabling precise time-of-flight distance and position measurement substantially more accurate than conventional narrowband positioning… Concept/Framework 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 Uninterruptible Power Supply A battery-backed power device that provides immediate, short-duration backup power to connected equipment upon main power loss, along with continuous power conditioning during normal operation, bridging the gap until backup… Hardware Upconverter Upconverter is a frequency conversion stage that shifts a signal from a lower frequency to a higher frequency for transmission or further processing by mixing the input signal with a… Hardware 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 Utility Facility A utility facility is a site containing systems and infrastructure used to produce, distribute, or manage an essential utility service. It typically combines physical operations with control, communications, and protection… Concept/Framework UTM A consolidated security appliance combining multiple protective functions — firewall, intrusion detection and prevention, antivirus, content filtering — into a single managed platform, typically deployed as on-premises hardware at a… Hardware
