Access

Air-Gapped System Air-Gapped System is a system that is physically isolated from external networks or other untrusted connectivity paths to prevent direct network access. Concept/Framework Air-to-Ground Link An air-to-ground link is a communications link that enables data transfer between an aircraft and ground-based or space-based network systems. It is a mobility-sensitive transport path used for service, telemetry,… Concept/Framework Airborne Relay Airborne Relay is a communications relay carried by an aircraft, drone, or other airborne platform to extend coverage or bridge a gap by forwarding communications over terrain, distance, or damaged… Hardware Aircraft Telemetry Aircraft telemetry is the transmission of aircraft status, sensor data, and operational events to a receiving system on the ground or in another control domain. It supports analysis, maintenance, and… Operations AIS A VHF-based maritime protocol under which vessels automatically and continuously broadcast identity, position, course, speed, and navigational status data, received by nearby vessels and shore stations terrestrially and, via Satellite-AIS,… Protocol Ambient IoT An emerging connectivity technology category for devices that operate without a battery, harvesting the energy needed for intermittent transmission from ambient sources such as RF signals, light, or vibration, introduced… Concept/Framework AMR A remote meter reading technology transmitting periodic consumption totals outbound from the meter using one-way radio or power-line communication, eliminating the need for manual meter reading while providing no return… Concept/Framework Antenna Gain Antenna Gain is a measure of how effectively an antenna concentrates energy in a given direction compared with a reference antenna. It influences both transmit and receive performance. Hardware Anycast Routing Anycast Routing is a routing approach in which the same address is advertised from multiple locations and traffic is sent to the nearest or best reachable one. Protocol Authentication Authentication is the process of verifying the identity of a user, device, or system. It establishes whether a claimed identity is valid before access is granted.
