Abstract. Broadband IP-based multimedia services are rapidly growing and there is the trend to use these services everywhere. Due to the fact that passengers in long distance high speed trains have a very comfortable environment to use their own terminal equipment, e.g. laptops with IEEE802.11×WLAN capability, it seems to be very promising to deliver broadband internet into trains. The challenge is the land-train connection where a high bit data rate link, e.g. 1Mbps in average in up- and downlink, has to be provided to enable several users within the train broadband internet access at the same time even at high speeds of the train. This paper describes a systematic approach starting at basic propagation measurements in a typical train environment and ending up with lab investigations by means of hardware channel simulation for different existing radio technologies which are candidates for the land-train connection.

The Impact

Abstract Digital technologies like the Internet can affect income inequality through increased demand for employment in manual and abstract jobs and reduced demand for employment in routine jobs. In this paper, we combine city-level income distribution and jobs data with broadband data from France to investigate the impact of broadband Internet access on income inequality. Using an instrumental variable estimation strategy, we find that broadband Internet reduces income inequality through increased employment in manual jobs. These effects increase with the availability of skilled workers and are significant in cities with a large service sector or high-speed Internet access. Further, the diffusion of broadband Internet comes with relatively greater benefits in low-income cities compared to high-income cities. Several robustness checks support these findings.

Roll Out

How does the changing information environment affect the degree to which voters make independent decisions for different offices on their ballots? Leveraging the gradual roll-out of broadband internet across the United States and across congressional districts, this study uses within-district variation over four election cycles to examine the effects of internet access on voting behavior in US legislative elections. The results show that the expansion of broadband resulted in less split-ticket voting and a lower incumbency advantage because voters exposed to increased high-speed internet voted in a more partisan fashion. Consistent with work demonstrating the effect of the internet on local news consumption, the results suggest that the change in the information environment resulting from enhanced internet access led voters to prioritize national considerations over local considerations. This has important consequences for not only how voters act, but the resulting incentives that elected officials confront.

Positive Effect

The paper examines influence of high-speed (broadband) Internet on fertility choice analyzed Russian panel data based on RLMS-HSE from 2014 to 2018. Using an instrumental variables strategy that exploits variations of broadband Internet access for households we find that determined broadband internet use leads to a positive effect on fertility for women of older reproductive age (from 25 to 49) and birth of second and further child is more affected. We attribute this effect to the ability of teleworking and building a better work-life balance. From our results this mechanism is relevant only for women with secondary and higher vocational education, that are more likely to work in professions with a higher probability of telework.

Network mobility (NEMO) enables seamless and ubiquitous Internet access while on-board vehicles. Even though the Internet Engineering Task Force (IETF) has standardized the NEMO basic support protocol as a network layer mobility solution, little studies have been conducted in the area of authentication, authorization, and accounting (AAA) framework that is a key technology for successful deployment. In this article, we first review the existing AAA protocols and analyze their suitability in NEMO environments. After that, we propose a localized AAA framework to retain the mobility transparency as the NEMO basic support protocol and to reduce the signaling cost incurred in the AAA procedures. The proposed AAA framework supports mutual authentication and prevents various threats such as replay attack, man-in-the-middle attack, and key exposure. Performance analysis on the AAA signaling cost is carried out. Numerical results demonstrate that the proposed AAA framework is efficient under different NEMO environments.

Subject The US digital divide over broadband internet access and its implications. Significance A digital divide between those that can use the internet at broadband speeds and those that cannot is persisting. Impacts Government support for digital provision will likely include direct public sector spending and opportunities for private firms. Expanded digital provision will benefit the currently underserved rural and low-income inner-city areas. Those without access to high speed internet will be disadvantaged in terms of education and accessing jobs. Expansion of 5G could exacerbate digital divides: affluent areas may be connected first, absent incentives to do otherwise.
