Cellular, Cell-less, and Everything in Between: A Unified Framework for Utility Region Analysis in Wireless Networks
This study connects the geometry of network utility regions -- such as SINR and achievable rates -- to the concept of nonlinear spectral radius. In doing so, it reveals when scheduling offers no extra gains and identifies regimes in which...
Linewidth Narrowing of InP-Based Lasers by Self-Injection Locking With a Monolithically Integrated Ring Resonator
A new monolithically integrated self-injection locking scheme, based on a ring resonator and a reflector, is demonstrated for InP lasers. We analyze and compare three different configurations, focusing particularly on the Lorentzian linewidth: an...
Deep Unfolded Superiorized POCs for Robust Joint Transmission under Phase Misalignment
DU-S-POCS achieves robust joint transmission in Wi-Fi networks despite phase misalignment between access points. By explicitly accounting for noise variance and combining superiorization with deep unfolding, it demonstrates consistent spectral...
Visualisation of Real-Time Environmental Data with Augmented Reality
This paper introduces a framework, a visualisation concept, and a prototype AR application designed to overlay environmental information, such as air quality and traffic data, onto the user’s view. The software framework is capable of easily...
6G upper mid-band independently controllable dual-polarized reconfigurable intelligent surface (RIS)
A dual-polarized RIS unit cell for the 6G upper mid-band is presented and experimentally validated using a 3x3 prototype. The proposed design enables independent control of orthogonal polarizations while maintaining high isolation, demonstrating...
Scaling Optical Testbed Data Space for Data Sharing Across Vendor and Organizational Boundaries
We demonstrate a data-sharing platform enabling on-demand sovereign data exchange across optical testbeds and system vendors to support ML development and predictive maintenance, through advanced vendor-, anonymization-, and purpose-based...
End-to-End GSNR Estimation While Securing Vendors’ Trade Secrets and Operators’ Confidentiality
We propose a Secure Multi-Party Computation protocol for GSNR estimation in disaggregated networks without exposing per-domain values, including back-to-back TRx characteristics, while demonstrating accuracy comparable to GNPy and analytical...
Demonstration of Customer-Owned and Carrier-Controlled Coherent Pluggables using Ownership-Aware YANG Models
We demonstrate a governed control framework that validates NETCONF operations against customer-defined policies using augmented YANG models and dataspace connectors, enabling carrier control of customer-owned coherent pluggables within a live...
Experimental Demonstration of Neural-Network Based Transceiver Nonlinearity Mitigation for Probabilistically Shaped Photonic THz Wireless Transmission
To mitigate front-end nonlinearities in probabilistically shaped photonic terahertz links, we experimentally demonstrate a NAS-optimized CNN–BiLSTM nonlinear equalizer trained with an entropy-regularized loss function. Across lens- and...
Distributed Intelligence Framework with Privacy-Preserving Features for FTTR Network Monitoring and Automation
This work demonstrates a novel distributed intelligence framework for fiber-to-the-room networks, designed to collect telemetry data locally and utilize them for autonomous network reconfiguration and management, while ensuring data...
