Why this course matters in 2026
By 2026 telecom networks are disaggregated, cloud‑native, and edge‑centric, which multiplies integration challenges across RF, protocol stacks and cloud orchestration. Employers want engineers who not only know standards but can reproduce issues in lab conditions, correlate traces across UE/gNB/core, and produce KPI‑backed remediation plans. This course bridges academic knowledge and production readiness with hands‑on labs, automation, and operator‑style reporting.
Who should take it and expected outcomes
The program fits RF engineers moving into testing, software engineers seeking RAN experience, fresh graduates eyeing telco roles, and test/QA engineers responsible for ORAN, MEC or CNF validation. Graduates decode RRC/NAS calls, validate PHY/MAC behavior under realistic channels, deploy CNFs on Kubernetes, validate NEF/MEC flows, automate regression suites, and present capstone reports that demonstrate immediate employability.
Course structure: modules and timeline
A practical course runs 8–16 weeks full‑time or part‑time variants across 12–24 weeks. Weeks 1–3 cover PHY, MAC and transport basics; Weeks 4–6 focus on RRC/NAS and trace analysis; Weeks 7–9 cover ORAN, RIC and E2/xApp labs; Weeks 10–12 include MEC/NEF, cloud CNFs and CI/CD; final weeks focus on capstones, soft skills and placement prep. Each module pairs concise theory with lab hours and graded deliverables.
Hands‑on lab stack: SDRs, protocol testers and emulators
Labs use USRP/NI SDRs for RF experiments, Keysight/Rohde & Schwarz protocol testers for signaling and throughput, and channel emulators for fading/Doppler patterns. Soft cores (Open5GS/free5GC) provide core network stacks, while ORAN CU/DU/CU testbeds and Kubernetes clusters host CNFs. Observability stacks (Prometheus/Grafana, Jaeger) and Wireshark 5G dissectors complete the toolchain, enabling end‑to‑end validation.
PHY to NAS: what testers must know
Testers must grasp PHY elements—modulation, LDPC, DM‑RS and PTRS—because these underpin link quality and estimation. MAC handles grants, scheduling and HARQ behavior that directly affect throughput and latency. RLC/PDCP manage reliability, reordering and security, while RRC/NAS govern attachments, mobility and bearer lifecycle. Understanding cross‑layer interactions helps you trace KPI anomalies to protocol or RF root causes.
Protocol trace collection and log analysis best practices
Effective debugging needs synchronized logs from UE modems, O‑RU/O‑DU/O‑CU, core functions, packet probes and observability telemetry. Best practices include PTP/NTP synchronization, consistent verbosity levels, structured log retention and standardized formats. The course teaches time alignment, sequence diagram creation, event correlation and building annotated evidence for operator and vendor escalation.
RRC and NAS troubleshooting scenarios
Common RRC/NAS issues include attach failures, reestablishment loops, mobility drops and paging inefficiencies. Labs recreate attach/auth failures, handover failures, and RRC reconfiguration errors, teaching students to map traces to timers, measurement gaps or misconfigured parameters. The emphasis is on reproducible steps and producing concise remediation steps operators can act on.
PHY/MAC test cases: HARQ, DM‑RS, PTRS and scheduling checks
PHY/MAC tests validate HARQ timing, redundancy versions, DM‑RS patterns for channel estimation and PTRS for phase tracking. Scheduler validation covers CCE utilization, MCS stability, and PRB allocation under load. Students run BLER/EVM measurements, reproduce HARQ backlog, and verify scheduler fairness under multi‑UE stress—real faults that impact throughput and user experience.
PDCCH/PDSCH/PUSCH validation and KPI interpretation
Control‑plane and data‑plane verification tests include DCI format accuracy, CORESET and search space mapping, and resource allocation for PDSCH/PUSCH. Measured KPIs include PDCCH BLER, PDSCH throughput percentiles, PUSCH PER and latency percentiles. You’ll learn to correlate DCI events to user‑plane KPIs and recommend scheduler or PRB tuning to meet acceptance thresholds.
ORAN fundamentals: splits, fronthaul and interoperability
ORAN separates O‑RU, O‑DU and O‑CU with fronthaul split options (e.g., 7.2) affecting latency and processing distribution. Training explains functional splits, PTP/SyncE synchronization needs, and fronthaul transport behavior. Interop labs focus on jitter tolerance, packet loss resilience, and graceful fallback—essential skills for multi‑vendor ORAN rollouts.
RIC & xApp testing: E2 interface and closed‑loop flows
RIC enables near‑real‑time RAN control through xApps that subscribe to events and send control actions over E2. Modules cover E2 service models, subscription flows, and safe closed‑loop designs. Hands‑on tests validate xApp decision correctness, load behavior, and fallback mechanisms to ensure automation improves KPIs without risking stability.
Cloud‑native RAN: CNFs, Kubernetes, Helm and CI/CD
CNFs package RAN functions as containers deployed on Kubernetes; engineers must write Helm charts, set liveness/readiness probes, and define resource quotas. CI/CD pipelines automate conformance and regression tests, enabling safe upgrades. Observability with Prometheus/Grafana and tracing with Jaeger help you debug across microservices during integration and rollout.
MEC in 5G: architecture, benefits and validation scenarios
MEC brings compute close to users to meet latency and data‑locality requirements for real‑time apps. Curriculum covers MEC host architecture, orchestration, service placement and local breakout. Labs validate end‑to‑end latency, session continuity during mobility, and resource isolation for enterprise apps—ensuring MEC deployments meet SLAs for AR/VR, industrial automation and low‑latency analytics.
Role of NEF in 5G Core and API exposure testing
NEF exposes network capabilities to authorized third parties via secure APIs, enabling application monetization and enterprise integrations. Training includes NEF subscription semantics, QoS/charging exposure, and authentication/authorization practices. Practical exercises test NEF payload integrity, rate limiting, and mapping from network triggers to application notifications under realistic loads.
MEC vs Cloud computing: trade‑offs and test approaches
Edge provides ultra‑low latency and data locality advantages, while central cloud offers scale and aggregated analytics. The course trains engineers to decide based on latency budgets, data sovereignty, orchestration overhead and cost. Comparative tests emulate app workloads on MEC vs cloud to measure tail latency, jitter and operational complexity under failure scenarios.
Real‑time 5G applications and industry use cases
Use cases like remote surgery, AR/VR, industrial control and connected vehicles require deterministic latency, reliability and failover strategies. Labs simulate these workloads to test slicing, MEC placement, QoS enforcement and session continuity under mobility. Case studies illustrate how lab metrics map to operator acceptance criteria and service‑level objectives.
AI and edge computing: testing strategies and telemetry needs
AI inference at the edge needs consistent inference latency and resource isolation. Modules cover model cold‑start behavior, runtime contention, telemetry capture for model and network KPIs, and orchestration policies for scaling inference. Tests include stress runs with varying network load to observe impacts on latency and throughput and to tune placement and scheduling.
5G private networks: deployment and testing examples
Private 5G for factories, campuses, and logistics centers demands predictable QoS, secure device onboarding and tenant isolation. Training includes private core deployments, NEF/MEC integration for enterprise apps, and slicing policy tests. Labs validate SLA enforcement, device provisioning flows and disaster recovery to ensure enterprise readiness.
Security, conformance and vulnerability testing
Security exercises include spoofing and replay attack simulations, malformed message injection, and CNF hardening checks. Conformance labs verify behavior against 3GPP and ORAN normative clauses under error conditions. Students learn to document vulnerabilities, prioritize fixes and perform follow‑up validation—critical steps before operator acceptance and production rollouts.
Test automation, regression suites and CI integration
Automation ensures repeatability and shortens validation cycles. You’ll learn Python scripting, Robot Framework or vendor SDKs to orchestrate SDRs, drive test flows, collect KPIs and parse logs. Regression suites integrated with CI (Jenkins/GitLab CI) run nightly or pre‑merge to catch regressions early and produce reproducible defect tickets for development teams.
Capstone projects: what you’ll build and present
Capstones replicate operator acceptance tests: ORAN multi‑vendor interop, RIC/xApp closed‑loop validation, MEC app latency SLA, or CNF upgrade regression. Deliverables include an executive summary, KPI dashboards, annotated traces and sequence diagrams, root‑cause analysis and remediation recommendations—professional artifacts you can present to recruiters and hiring teams.
Career pathways and hiring signals in 2026
