Key Points Describes blocked or unavailable communications May result from jamming, policy, or failure Important in contested or constrained environments Applies to satcom, Government & Defence, and remote operations Denial may originate from interference, outage, restrictions, or environmental limits Definition…
Key Points Collects remote measurements and status data from distributed assets Transmits data to centralized monitoring or control points Supports real-time visibility and analysis of remote operations Pairs sensors with communication links for end-to-end data flow Critical for managing systems…
Key Points Decision process for allowing or rejecting new demand into a system Protects resources and maintains service quality Used in telephony, network services, traffic engineering, and shared-capacity systems Prevents overload by rejecting or delaying new demand when capacity is…
Key Points Increasing node density to improve coverage or capacity Used in operational and architecture contexts Works by placing more service points closer together so each node serves a smaller share of geographic or user demand Used in mobile networks,…
Key Points Uses electricity to create thrust Typically offers high efficiency and low thrust Common in long-duration spacecraft missions Trades thrust level for efficiency and endurance Requires sustained power availability Definition Electric Propulsion is a propulsion method that uses electrical…
Key Points Repeated controller sequence for sensing, logic, and actuation Defines how a controller interacts with the process over time Influences how quickly a controller can detect changes and issue new commands Used in industrial automation, PLCs, and control systems…
Key Points Allocates capacity dynamically rather than statically Used in access and shared transport systems Improves utilization under variable demand Requires scheduling or control logic Balances service needs against the limits of a common medium Operates by monitoring usage, queue…
Key Points Lowers output below maximum drive Used in RF transmitters and amplifiers Helps reduce distortion and spectral regrowth Important in multi-carrier operation Improves linearity and reduces intermodulation distortion Definition Carrier Backoff is the reduction of transmitter output level to…
Key Points Network Slicing is a service delivery model that operates at the Transport system layer Logical separation of network resources enables differentiated service requirements Enables multiple logical networks with different performance, security, or policy needs to coexist on shared…
Key Points Control method using output feedback to regulate a process Continuously corrects based on measured results Used in operational and control contexts Standard form of feedback regulation in physical systems Definition Closed-Loop Control is a control method that uses…
