Telecommunications

Software Defined Payload Software Defined Payload is a communications payload whose functions are controlled, configured, or reconfigured through software rather than being fixed entirely by hardware design. Hardware Solid-State Power Amplifier Solid-State Power Amplifier is a power amplifier that uses semiconductor devices rather than vacuum tubes to increase RF output power. Hardware Spectral Efficiency Spectral Efficiency is the amount of useful information transmitted per unit of spectrum, usually expressed as bits per second per hertz. It measures how effectively spectrum is converted into usable… Concept/Framework Spectrum Spectrum is the range of electromagnetic frequencies used for communication, sensing, and other radio-related functions. It is the underlying resource for wireless systems. Concept/Framework Spectrum Coordination Spectrum Coordination is the planning and management of radio spectrum use to reduce interference and allow compatible services to operate. It aligns technical and regulatory use of frequency resources. Operations Split Horizon Split Horizon is a routing rule that prevents a router from advertising a route back out of the same interface or direction from which the route was learned. Protocol Spot Beam Spot Beam is a narrow, focused satellite or radio beam that concentrates energy on a limited geographic area. It provides localized coverage with higher directional gain. Hardware Star Tracker Star Tracker is an optical attitude sensor that determines spacecraft orientation by identifying stars in its field of view and comparing observed star positions with an internal catalog to compute… Hardware Stateful Inspection Stateful Inspection is security inspection that evaluates traffic in the context of an existing connection or session state. It uses remembered context to guide policy. Software Stateless Communication Stateless Communication is communication in which each message is handled independently without relying on stored session context. Protocol
