This metric is crucial for distinguishing between innovation actions aimed at early-stage innovations and market-ready solutions. Ideally, EU-funded research and innovation projects should lead to the development of innovative concepts and technologies by EU industries, which in turn enhance security capabilities within EU member states. However, there is a notable challenge: the adoption rate of outcomes from EU-funded security research and innovation projects is not as high as expected. The current TRL maturity assessment method is insufficient in exposing the possible cause of the limited uptake by fully pointing out where the development is lacking. The TRL's limitations include a lack of comprehensive assessment from various perspectives especially in the civil security research and projects, which is necessary to bridge the gap, often referred to as the \"valley of death,\" between project results and their effective adoption. To address these shortcomings, in the MultiRATE EU research project we propose a holistic framework that enhances the TRL scale by adding additional Readiness Levels (RLs) for a more complete evaluation of security projects. These include the Societal RL (SocRL), Security RL (SecRL), Legal, Privacy and Ethical RL (LPERL), Integration RL (IRL), Commercialisation RL (CRL), and Manufacturing RL (MRL). In this open letter, we explain the background of the design considerations of this framework. Our goal is to define and integrate these seven Readiness Level (RL) dimensions and an investment forecasting tool to support policy makers, practitioners, and investors in bridging the \"valley of death\" between research and adoption.</p>","PeriodicalId":74359,"journal":{"name":"Open research Europe","volume":"5 ","pages":"115"},"PeriodicalIF":0.0,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12949380/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147328390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional RF-based wireless systems are susceptible to EMI, limited spectrum availability, and security issues. Direct-Modulated Laser (DML)-based Light Fidelity (LiFi) offers a promising alternative by leveraging the visible spectrum for high-speed, interference-free communication in terms of intended optical emissions. Methods The optimized configuration achieves BER well below the commonly cited analytical reliability benchmark ( <i>BER</i> < <math><msup><mn>10</mn> <mrow><mo>-</mo> <mn>9</mn></mrow> </msup> </math> ), <i>SNR</i> ≈ 74.94 dB, and <i>Q</i> ≈ 18.84 at 25 m, under idealized detector-noise-limited assumptions.

The article reviews the four main approaches to navigating the CBAM trilemma and examines the resulting trade-offs between policy goals.

The second approach involves setting differentiated CBAM liabilities for third countries, depending on their level of development, or granting some of them full exemptions from the policy.
