Private 5G Networks / 5G Non-Public Networks (NPNs)

Explore ultra low latency features for private 5G networks, including variable subcarrier spacing from 15 to 40 kHz, mini slots, configured grants, and downlink preemption to reduce latency.

Private 5g networks boost reliability with multi slot repetition, lower modulation and coding at cell edge, and dual active protocol stack handover with data duplication.

Private 5G networks let you customize quality of service for each application by configuring QoS flows within a PDU session, balancing latency and guaranteed bit rate.

Explore network slicing: multiple virtual networks on shared infrastructure, with each slice delivering a private 5G service for mobile broadband, machine to machine, and ultra reliable, low latency.

Identify 5G private frequency bands, Fr1 (410 MHz–7125 MHz) and Fr2 (24.25–52.6 GHz), and explain their coverage, capacity, and use cases from IoT to high-throughput millimeter wave.

Understand licensed spectrum for private 5G, with dedicated geographic areas offering predictability and low interference, and access routes via public land mobile networks or regulators, e.g., 3.7–3.8 GHz in Germany.

Discover how shared spectrum lets secondary private LTE networks use frequencies not in use under a database assisted sharing model and the spectrum access system, while incumbents retain priority.

The standalone non-public network (SNPN) deploys as an isolated, independent 5G network, requiring a subscription and a unique SNPN ID broadcast by the system.

A SNPN-registered device uses its subscription to access the public 5G network via untrusted non-3GPP access, establishing an IPsec tunnel through the 3iwf to enable data, signaling, and QoS.

Public network integrated non-public networks deploy as slices with a public network subscription, and three deployment models: shared ran, shared ran with control plane, and hosted by public network.

Explore how shared RAN and control plane let public core functions support a private 5G network, with data via UPF and subscriptions to public networks, plus IPsec, firewalls, and slicing.

Explore how the public 5g network hosts both public and non public networks, using shared control and user plane functions, with network slicing supporting isolated traffic and low-latency edge computing.

Explain how the closed access group (CAG) in private 5G networks restricts access by broadcasting cell access group IDs and matching them with UE subscriptions, denying mismatched access.

Explore how private 5G networks enable time sensitive networking within industry 4.0, using IoT and cloud computing to automate and optimize complex manufacturing processes across the four industrial revolutions.

Demonstrate how time sensitive networking enables deterministic communication, replacing IP-based payload with industrial protocols over Ethernet at layer two and extending to 5G wireless as layer one.

Define a TSN flow as time-critical communication between end devices, talker and listener, via TSN-enabled bridges. CNC determines routes and timing, configures bridges, and CU conveys requirements to reserve resources.

Maintain time synchronization in time sensitive networking with a master clock and generalized precision time protocol (gPTP) across end devices and bridges.

The 5G system acts as a bridge to TSN domains, enabling generalized precision time protocol synchronization and mapping TSN flows to QoS across control and user planes via TSN translator.

Explain how the TSN application function interfaces with the 5G control plane to support the central network controller in managing the TSN network and bridge, including signaling with TSN translators.

explain network exposure function in 5g networks, securely exposing functions to a third party or external network via the tsn application function; in the same trust domain, nef is unnecessary.

SMF establishes and manages BW session by selecting UPF, allocating IP for the PD session, coordinating QoS with PCF, and sharing port and MAC addresses with TSN to map flows.

The PCF uses the UDM user profile to set policy, QoS, and mobility management rules for sessions. It transfers rules to the SMF and supports TSN bridge detection and scheduling.

Explore the access and mobility management function (amf) in the control plane, handling signaling with user equipment for connection and mobility management and passing authentication signaling through mf.

five g acts as a tsn bridge with device and network translators applying hold‑and‑forward and priority queues, while link layer discovery maps topology and signals translators via tsn application function.

Examine how TSN and Five G Network use master clocks to synchronize core network elements, with microservices on a cloud server, while devices and translators align, and synchronizations run independently.

Describe clock synchronization flow in 5G, from the master clock to the core network, GNB, UE, and finally UPF via time protocol links.

Explain clock flow from upstream TSN domain to downstream TSN domain through the Five G network, a TSN bridge, and how the translator and user plane function report drift.

Explore the interworking of 5G and TSN networks, detailing the 5G TSN bridge detection, bridge information reporting, and TSN traffic scheduling on the 5G TSN bridge.

Learn how a central network controller uses 5G TSN bridge topology to schedule TSN traffic, outputs gate control lists for TSN translators, and maps flows to QoS with traffic characteristics.
