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.

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.

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.

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.


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.

The Australian government has recognised the importance of broadband for their social and economic development. This paper provides an in-depth analysis of the impact of policy issues on broadband Internet access in Australia. This research has clearly indicated that the state of broadband Internet access is closely related to the Government’s policy and regulatory framework. The Government based its actions on market forces as a principal driver for broadband Internet connectivity. The research has indicated that the previous regulatory competition regime, by and large, has failed to address concerns of market dominance and market power in the Telecommunications sector as is evidenced by a relatively lower speed and value of broadband services in Australia. To rectify the situation, the Australian government has recently adopted a unique National Broadband Network (NBN) plan, which is linked to the national digital economy strategy. Australia is the first country in the world where a national broadband network infrastructure company, NBN Co, is regarded as a regulated national infrastructure provider rather than as a telecommunication company. The NBN Co builds and operates an open access, wholesale only and non-discrimination high-speed broadband network, the National Broadband Network (NBN). The Australian Government's goal for the NBN is to reform the telecommunications sector and ensure every home and business across the country has access to the NBN by 2020. This paper examines the policies underlying the NBN and discusses current practices and potential benefits of the NBN.
