The research paper compares the OpenAirInterface and srsRAN platforms across both qualitative deployment features and quantitative radio performance metrics. Prior evaluations often relied on single-platform testbeds or lacked varied hardware and real user equipment contexts. Barbosa's assessment addresses these shortcomings by reviewing radio resource control setup procedures, theoretical data rate compliance, and real-world application handling. Performance was specifically measured against high-throughput Video on Demand as well as latency-critical workloads like Cloud Gaming.

Title:Open-Source 5G RAN Platforms: A Dual Perspective on Performance and Capabilities
View PDFAbstract:Open-source implementations of the fifth generation (5G) Radio Access Network (RAN), such as OpenAirInterface (OAI) and srsRAN, have become increasingly relevant for industry and academic research, rapid prototyping, and low-cost private 5G deployments. The state of the art presents different evaluation scenarios for both platforms; however, these are often limited to individual testbed evaluations, end-to-end studies, or partial comparisons between them. In particular, there is a lack of evaluations considering different Software-Defined Radios (SDRs), RAN configurations, user applications, and numbers of real UEs. To address this gap, this paper presents a comparative evaluation of OAI and srsRAN. The study includes a qualitative assessment of supported features and deployment flexibility, followed by a quantitative performance analysis covering radio resource control setup procedures, compliance with theoretical data rates, and real application workloads with diverse quality of service requirements. Specifically, we consider Video on Demand (VoD) for data rate evaluation, Live Streaming (LS) and Cloud Gaming (CG) as latency-sensitive…
Unauthorized access to internal systems resulted in the copying of user records across Singapore and Hong Kong after being detected on October 29. The incident exposed contact details and sensitive reward claim information for individuals using the platform to compare or apply for financial products. Company operations remain normal while regulators, including the Personal Data Protection Commission, have been notified and external cybersecurity investigators examine the scope.
Cyber attackers penetrated the personal finance portal's internal systems on Oct. 29, copying sensitive records submitted by customers seeking credit cards, loans, and insurance products. The incident exposed identifying credentials and financial profiles across two major Asian markets, prompting corporate outreach and regulatory notifications. The platform has contained the intrusion while forensic investigators assess the full scope of the compromise.
The unauthorized intrusion into the financial portal's internal systems exposed sensitive identity documents, income brackets, and insurance records across two key Asian markets. Independent digital forensics experts have been engaged to investigate the intrusion while the platform continues standard daily operations. Regulators across both jurisdictions have been formally notified as the company works to prevent future network vulnerabilities.
