Access

NAVTEX A GMDSS subsystem that automatically broadcasts and receives navigational, meteorological, and maritime safety warnings over a dedicated medium-frequency radio channel, with receiving equipment aboard vessels automatically printing or displaying relevant… Protocol NB-IoT A 3GPP-standardized cellular radio access technology optimized for low-power, low-data-rate, wide-area IoT connectivity, operating within licensed cellular spectrum and typically deployable via a software upgrade to existing LTE or 5G… Protocol Network Access Control The discipline of verifying a device's identity and security posture before granting it network access and continuously enforcing policy on what that device can reach once connected, rather than granting… Concept/Framework Network Address Translation Network Address Translation is the translation of one address space into another, usually to allow private addresses to communicate with public networks. It rewrites address information at a boundary. Protocol Network Connectivity Network connectivity is the condition in which networked systems can establish and maintain communication paths. Concept/Framework Network Densification Network Densification is the increase in the number of network nodes, access points, or base stations in a given area to improve capacity or coverage. Operations Network Telemetry Network Telemetry is the collection and export of operational data from network devices and services for monitoring and analysis. Operations New Radio The 3GPP-specified air interface for 5G, defining the physical layer waveform, flexible numerology, and radio protocol stack (PHY, MAC, RLC, PDCP) that terrestrial base stations and non-terrestrial network payloads alike… Protocol Nonlinear Amplification Nonlinear Amplification is amplifier behavior in which output is not perfectly proportional to input, often causing distortion or spectral regrowth. It can degrade signal quality. Hardware NTN Cell The 3GPP-recognized radio coverage area served by a non-terrestrial network node, defined by a Cell ID and system information broadcast, within which user equipment performs cell selection, camping, and connection… Concept/Framework
