Why does this matter operationally?
Cost Efficiency
The discipline of delivering required connectivity performance at sustainable operational and capital cost. Cost efficiency in connectivity involves trade-offs between link capacity, redundancy, technology choice, and managed service dependency.

Distance Vector Routing
Distance Vector Routing is a routing method in which routers share distance information with neighbors to reach destinations, building routes iteratively based on advertised metrics.
Concept/Framework
Distributed Energy Resource
Any small-scale electricity generation, storage, or controllable load asset connected at or near the point of consumption rather than through centralized utility-scale generation, encompassing rooftop and community solar, battery storage,…

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 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 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-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
Electric Propulsion
Electric Propulsion is a propulsion method that uses electrical energy to accelerate propellant and produce thrust. It converts electrical power into directed motion.
