Frequency Coordination Frequency Coordination is the planning and negotiation of frequency use so different systems can operate without harmful interference. Operations Frequency Hopping Frequency Hopping is the periodic change of carrier frequency according to a predefined or adaptive sequence. Protocol Frequency Mixing Frequency mixing is the process of combining two or more signals to generate output signals at new frequencies, typically the sum and difference frequencies. It is used to translate signals… Concept/Framework Frequency Stability Frequency stability is the degree to which a signal source maintains its intended frequency without drifting beyond acceptable limits. It is a measure of how reliably the source remains usable… Concept/Framework Functional Safety Functional Safety is the part of safety engineering that ensures a system performs the correct protective action when hazardous conditions occur. It focuses on safety-related functionality and protective behavior under… Operations Gateway Diversity Gateway Diversity is the use of multiple gateway paths, sites, or providers to reduce dependency on a single gateway point of failure. Concept/Framework Gateway Handover Gateway Handover is the transfer of service traffic from one gateway to another to maintain connectivity or optimize performance. Operations Gateway Site Gateway Site is the physical location where gateway equipment, antennas, and supporting infrastructure are installed and operated. Hardware GEO GEO is geostationary Earth orbit, an orbital regime where a satellite remains approximately fixed relative to a point on Earth. It supports persistent coverage of a region through orbital mechanics… Concept/Framework Graceful Degradation Graceful Degradation is the controlled reduction of system capability so a service continues operating in a limited or simplified form during stress or failure. It preserves partial function. Operations
