Summary: This article discusses the use of an innovative public-private partnership approach to drive broadband deployment and build more resilient telecommunications networks in Puerto Rico after the devastation caused by hurricanes. The proposed partnership also aims to enhance citizen access to broadband services throughout the island. This work is part of the Congressionally mandated economic and disaster recovery plan for Puerto Rico.

Summary: This paper investigates the economic effects of improved broadband access at the firm level. The results show that increasing broadband speeds can improve the financial performance of small firms, but do not increase their intangible capital share. The study suggests that the digital transition for small firms should focus on the causes of adoption and move beyond policies aimed at increased broadband availability alone.

Summary: There is growing interest in using satellites to complement terrestrial networks for broadband access service provision. Matching the non-uniform on-ground traffic distribution is a key challenge, and it can be addressed through large frequency reuse among satellite beams and the use of interference mitigation techniques. Recent advancements in space technology have made it possible to implement active antennas operating at 20-30 GHz, which opens up new possibilities in flexible system and payload design. The application of Massive MIMO techniques to satellite networks is stimulated by the presence of a large number of antenna radiating elements on board the satellite.

Summary: Locally-initiated and operated Internet infrastructure projects aim to provide online connectivity and achieve social goals. Challenges in scaled developments exist in the U.S. despite various generations of DIY network efforts. Non-economic benefits can be realized with certain technologies and organizational structures, potentially leading to improved outcomes for connectivity with supportive policies.

Summary: The article discusses the legacy of national monopoly providers in the telecommunications industry after liberalization in Europe and North America, as well as the potential issues arising from regulators' assumptions of national markets and cautious regulatory policies. It suggests that a more geographically varied and technologically agnostic regulatory framework may better satisfy regulatory principles.

Summary: Telecommunications fraud causes significant economic losses worldwide annually. Although Graph Neural Networks (GNNs) offer new possibilities for fraud detection, their performance in telecom fraud detection is unsatisfactory. This can be attributed to the lack of research on the deep fraudster phenomenon and the scarcity of available datasets. This paper addresses these issues by rearranging and publishing two real-world telecom fraud detection datasets and proposing a GNN-based semi-supervised method called BANADA. Extensive experiments demonstrate that our BANADA outperforms all state-of-the-art GNNs and GNN-based fraud detectors.

Summary: This article introduces the polynomial eigenvalue decomposition (PEVD) and its applications in broadband multichannel signal processing. Broadband signals have important commercial applications in various fields, and the performance of signal processing tasks often relies on the results of EVD. Therefore, PEVD is a new technique suitable for broadband signal processing.

Summary: The expansion of telecommunications has led to increasingly severe crosstalk and interference, which can be effectively addressed by blind source separation (BSS), a physical layer cognitive method. Previous electronic implementations were limited by narrow bandwidth and high energy consumption, but a new photonic BSS approach overcomes these limitations and achieves scalable BSS across a wide processing bandwidth of 19.2 GHz.

Summary: This study investigates the impact of digitalization on the organizational empowerment structure of firms and how it occurs. The authors use the DID strategy based on the Broadband China pilot policy to establish causality and find that digitalization leads to increased centralization levels in firms by reducing communication costs and enhancing productivity. Furthermore, this positive effect is more significant in state-owned enterprises and firms with lower agency costs.

Summary: Drones, functioning as air base stations (UAV-BSs), can be used to provide communication services when the network is overloaded or unavailable. However, the dynamic capacity of UAV-BSs may cause losses in electromagnetic signals, leading to transmission impairments. To address this, researchers proposed a 3D positioning strategy for UAV-BSs to optimize their placement and serve the maximum number of users with the minimum number of drones. Results showed that this strategy had wide coverage, excellent performance, and higher energy efficiency compared to other algorithms.

Summary: Livestock operations have become more intensified in recent decades, leading to the rise of large concentrated animal feeding operations (CAFOs). Intensification has both decreased production costs and caused significant environmental impacts, such as nutrient runoff. Implementing nutrient recovery systems in CAFOs can mitigate these impacts, but may affect their economic performance. Incentive policies for phosphorus recovery technologies in CAFOs are designed and analyzed, showing economic viability in larger operations due to economies of scale. For smaller operations, phosphorus credits progressively improve profitability.
