Access

Profibus Profibus is an industrial communication protocol used to connect automation devices, controllers, and field equipment. Protocol Proximity Services The 3GPP-defined framework of service capabilities — device discovery, direct device-to-device communication, and UE-to-network relay — built on sidelink communications, enabling devices in physical proximity to interact directly without requiring… Concept/Framework Push-to-Talk A half-duplex group communication model in which a user presses a button to transmit to an entire talk group and releases it to listen, delivered over dedicated trunked radio infrastructure… Concept/Framework QOS QOS is a set of mechanisms used to prioritize and manage network traffic by controlling how bandwidth, delay, and loss are handled for different traffic classes. Operations Queue Management Queue Management is the handling of packet queues in a device or system so delay, loss, and fairness can be controlled. Operations Radio Access Network A radio access network is the collection of radio access equipment, control logic, and supporting transport that connects endpoints to a mobile or wireless service. It manages radio resources, mobility,… Concept/Framework Ranging Signal Ranging Signal is a signal used to measure distance, timing, or propagation characteristics between endpoints or within a communications system. It provides a reference for ranging or calibration. Protocol Rapid Deployment Terminal Rapid Deployment Terminal is a communications terminal designed to be set up quickly for temporary or emergency use, providing fast-deployed connectivity through minimized installation steps and packaged connectivity equipment. Hardware RedCap A 3GPP Release 17 device category defining a reduced-complexity profile of the New Radio air interface — fewer antennas, reduced bandwidth, relaxed processing requirements — targeting mid-tier IoT applications between… Protocol Refuge Chamber Communications The communication systems and equipment integrated into underground mine refuge chambers, typically combining multiple independent methods — through-the-earth transceivers and hardened cable-based connections — to maintain a survivable communication path… Hardware
