Software Defined Networking Software Defined Networking is a network architecture that separates control logic from forwarding behavior and manages the network through software-based control. It decouples decision-making from packet handling. Concept/Framework 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 Spectrum Refarming The regulatory and operational process of reallocating spectrum previously licensed for one cellular technology generation to a newer generation, retiring or migrating the legacy technology's use of that band as… Operations Spectrum Sensing The process of detecting the presence, absence, and characteristics of RF activity on a candidate frequency channel, used to determine whether that channel is available for secondary or opportunistic use… 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
