Optical Wireless Communication for 6G Backhaul

Building on our established LED-based point-to-point links we present the next generation of optical wireless technology: LiFi 2.0.
Based on high-power VCSEL-array transmitters and low-noise APD-array receivers, we demonstrate a live system capable of 5 Gbps. Combining imaging optics and a DSP solution based on IEEE 802.13.15 we reach field of views of 60° without diminishing the data-rate.

Simple alignment during installation and rate-adaptivity during operation enable optical front- and backhauling with a reliability of 99.99% for future mobile communication systems and offers mobile operators new flexibility in developing their networks – as a capacity upgrade for existing wireless links, to improve resilience against adverse weather conditions or as a standalone solution for rapid or economical network development.

Data Sovereign and LLM-assisted Features for E2E Network Monitoring

This software prototype enables comprehensive monitoring of multi-vendor multi-domain packet optical network infrastructure and offers various data usage restrictions policies to enable cross-stakeholder telemetry data sharing while adhering to data confidentiality and NDA compliance regulations. The following new features will be showcased in our booth:

• LLM-assisted Network Copilot with NDA Compliance: This feature enables intuitive interaction with NETCONF/OpenConfig-enabled devices using simple human written prompts. This feature allows junior network admins deliver what can only be achieved by a highly skilled network admin for API client code generation and protocol specific response analysis and comprehension.
• Cross-stakeholder Data Sharing Policies: This feature offers various data usage restrictions policies for network data sharing, including anonymisation, time-based, location-based, and stakeholder-specific , based on International Data Spaces Association (IDSA) principles.

We showcase these features of NOBS through a set of demos carried out on an SDN-enabled packet optical networking testbed.
