Next-Gen Infrastructure Strategy: Total Optimization from 3D Design & Time Sync to GNSS Security & RF Measurement

With the advancement of Beyond 5G/6G and NTN (HAPS/LEO), telecom infrastructure faces unprecedented complexity. For carriers, securing network resilience and maximizing ROI is a paramount challenge.

In this seminar, Marubun Corporation, a leading electronics trading company, presents a comprehensive strategy. We connect cutting-edge global technologies to support the entire lifecycle of next-gen networks, from initial design to quality evaluation.

We will explain four core technological pillars mapped across design, construction, and field validation phases:

[3D RF Design]: Utilizing 3D digital twin technology to simulate propagation across complex urban and sky environments, preventing rework and optimizing CAPEX.

[NTN & GNSS Resilience]: Verifying vulnerabilities against threats like jamming and spoofing to protect vital satellite timing data, proposing robust security defenses.

[High-Precision PTP Synchronization]: Addressing the stringent nanosecond-level time sync measurement and retention requirements critical in O-RAN environments.

[RF Area Quality Measurement]: Leveraging high-performance scanning receivers for field testing to visualize QoE and optimize OPEX.

We demonstrate how our integration capabilities optimize all network layers—from manipulating radio waves to protecting infrastructure clocks. This 20-minute session condenses the future of infrastructure development, serving as a gateway to our live booth demonstrations.
