Deep Technical Insights into 5G, 6G, Open RAN & Future Wireless Networks
Latest Articles
Freshly published deep-dives across 5G, 6G, and Open RAN.
THz Communication: Why 6G Is Looking Past mmWave
What sub-THz and THz bands offer 6G, why molecular absorption and path loss make coverage brutal, the hardware problems that remain unsolved, and a realistic deployment timeline.
Semantic Communications: Sending Meaning Instead of Bits
What semantic communication actually proposes, where task-selective traffic reduction genuinely pays, and the metrics, robustness and interoperability problems still in the way.
Non-Terrestrial Networks: 3GPP Satellites, Delay Budgets, and Direct-to-Device
How 3GPP adapted NR for satellites: LEO/MEO/GEO trade-offs, the timing advance and HARQ changes long delays forced, transparent versus regenerative payloads, and what direct-to-device really delivers.
Integrated Sensing and Communication: Turning the Radio Network Into a Sensor
How ISAC extracts environmental information from radio signals, why massive MIMO and wide bandwidth make it viable in 6G, and the trade-offs standing between the concept and deployment.
Digital Twins in Telecom: A Proving Ground for the Live Network
What makes a network digital twin useful rather than decorative: the fidelity trade-off, high-value use cases, the data foundations required, and how twins support safe closed-loop automation.
AI-Native Networks: Designing 6G for Intelligence from the Start
The difference between AI-assisted and AI-native networking, why the data pipeline matters more than the models, and what explainability actually means in network operations.
5G
5G NR fundamentals through advanced RAN and core topics: architecture, protocols, scheduling, and more.
Non-Terrestrial Networks: 3GPP Satellites, Delay Budgets, and Direct-to-Device
How 3GPP adapted NR for satellites: LEO/MEO/GEO trade-offs, the timing advance and HARQ changes long delays forced, transparent versus regenerative payloads, and what direct-to-device really delivers.
What Is 5G NR? Numerology, Frequency Ranges, and the Flexible Frame
5G NR explained for engineers: scalable numerology, FR1 and FR2, the flexible slot structure, bandwidth parts, and what actually changed from LTE.
5G Interview Questions: What Gets Asked and How to Answer It
A structured 5G interview guide: the questions that actually come up across radio, RAN, core and QoS, worked troubleshooting and system-design scenarios, and a framework for answering well.
6G
Forward-looking research on 6G: AI-native networks, sensing, THz spectrum, digital twins, and semantic communication.
THz Communication: Why 6G Is Looking Past mmWave
What sub-THz and THz bands offer 6G, why molecular absorption and path loss make coverage brutal, the hardware problems that remain unsolved, and a realistic deployment timeline.

Integrated Sensing and Communication: Turning the Radio Network Into a Sensor
How ISAC extracts environmental information from radio signals, why massive MIMO and wide bandwidth make it viable in 6G, and the trade-offs standing between the concept and deployment.
Open RAN
Disaggregated RAN architecture, O-RAN interfaces, the RIC, and the open ecosystem reshaping radio networks.
What Is Open RAN? The Architecture, the Promise, and the Fine Print
Open RAN in plain terms: what operators are actually trying to achieve, what the architecture changes, and why 'open' does not mean plug-and-play.
O-RAN Architecture: Interfaces, RIC, and the Functional Split
A technical reference for the O-RAN architecture: the O-CU/O-DU/O-RU split, the O1, O2, A1, E2 and Open Fronthaul interfaces, and how the two RICs divide the control problem.
AI in Telecom
How AI and generative AI are transforming network operations, automation, and RAN intelligence.
Tutorials
Hands-on, step-by-step walkthroughs for configuring, measuring, and troubleshooting real network features.
Open RAN Tutorial: From Architecture to Your First xApp
A complete hands-on path into Open RAN: the architecture and interfaces that matter, an acronym decoder, standing up a lab with open-source components, writing an xApp against E2SM-KPM, and adding A1 policy.
Carrier Aggregation Tutorial: Configure, Measure, and Troubleshoot CA
A complete practical walkthrough of carrier aggregation: decoding UE band combinations, configuring PCell and SCells, timing advance groups, measuring real gain, and diagnosing every common activation failure.
Ask me to cover a new topic
There are 30 deep-dives here, but the list is nowhere near complete. If you are working on something in 5G, 6G or Open RAN that is not covered yet — or a section that needs more depth — tell me and I will put it on the queue.
