Downlink Power Control Downlink Power Control is the adjustment of transmit power on a downlink to maintain service quality or reduce interference. It is used to balance coverage and efficiency. Operations DWDM An optical transport technique that carries many independent signals simultaneously over a single fiber, each assigned its own tightly-spaced wavelength, multiplying a fiber route's effective capacity without requiring additional physical… Concept/Framework Dynamic Bandwidth Allocation Dynamic Bandwidth Allocation is the adaptive assignment of bandwidth based on demand, policy, or channel conditions. It is used to share capacity more efficiently. Operations Dynamic Routing Dynamic Routing is routing that automatically updates path selection based on network state or routing information. It adapts to changing topology and link conditions. Software Dynamic Spectrum Access A set of techniques and regulatory frameworks that allocate and reallocate radio spectrum access in real time based on actual usage and interference conditions, rather than through fixed, exclusive, long-term… Concept/Framework Earth Segment Earth Segment is the ground-based part of a satellite communications system that includes infrastructure supporting control, telemetry, tracking, and service access from Earth. Hardware Earth Station Earth Station is a ground-based satellite communications facility that transmits and receives signals to and from spacecraft. It provides the terrestrial side of the satellite link. Hardware Earth-Fixed Beam A satellite payload beam-steering technique in which onboard beam-steering continuously repoints a spot beam to compensate for the satellite's orbital motion, holding the beam's ground footprint — and therefore the… Concept/Framework Earth-Moving Beam A satellite payload beam architecture in which a spot beam points in a fixed direction relative to the satellite itself, without continuous onboard steering to compensate for orbital motion, causing… Concept/Framework EBGP EBGP is a BGP routing session used between routers in different autonomous systems. It supports inter-domain route exchange and policy enforcement. Protocol
