Broadband Satellite Networks

Satellites are the transmission medium for providing connectivity and building global, continental, or regional networks around the world (satellite operators effectively use satellites to support Internet traffic), and point-to-point connections are also possible. In practical use, there are combinations of VSAT networks with terrestrial wireless extensions, allowing end users to increase the capabilities offered via satellite. This paper provides selected information on broadband satellite networks using VSAT technology, including available protocols and transmission platforms. The aim of the article is also to present the chosen technical aspects of satellite networks working with the usage of VSAT technology.

Wimax Network

Every new technology comes with its challenges and lessons to be learnt. With a number of unknowns, deploying a new technology becomes a challenge. Worldwide Interoperability for Microwave Access (WiMAX) is one of these new technologies currently on the rise. This paper presents the finding of the research conducted to investigate technical and non technical aspects of network operators in Tanzania. The research looked into WiMAX network operational challenges faced by the network owners as well as the level of services experienced by the end users. This paper is suitable researchers, network operators and investors interested in WiMAX technology. It is mostly usefully for those looking into solutions to problem facing rural and remote areas of the world. The research is discussed in detail throughout of the article.

High Bandwidth

The aim of this chapter is to show the satellite Internet as a new quality, which was created thanks to the convergence of satellite communication and data networks. The chapter describes the development of satellite communication and satellite data networks, presents methods of Internet access via satellite and discuss the opportunities and challenges of building effective commercial services based on satellite Internet. The main advantages of the satellite Internet are high bandwidth, very good availability (in practice: anywhere in the world), and natural IP multicasting. Although getting broadband Internet access by satellite is considered very expensive, independence from the local infrastructure results in the satellite Internet being a good solution for both business communications (a corporate network or its fragments) and remote area communications (rural communications and services to isolated communities).

BACKGROUND Misinformation about COVID-19 has presented challenges to public health authorities during pandemics. Understanding the prevalence and type of misinformation across contexts offers a way to understand the discourse around COVID-19 while informing potential countermeasures. OBJECTIVE The aim of the study was to study COVID-19 content on two prominent microblogging platform, Twitter, based in the United States, and Sina Weibo, based in China, and compare the content and relative prevalence of misinformation to better understand public discourse of public health issues across social media and cultural contexts. METHODS A total of 3,579,575 posts were scraped from both Weibo and Twitter, focusing on content from January 30th, 2020, when the World Health Organization (WHO) declared COVID-19 a “Public Health Emergency of International Concern” and February 6th, 2020. A 1% random sample of tweets that contained both the English keywords “coronavirus” and “covid-19” and the equivalent Chinese characters was extracted and analyzed based on changes in the frequencies of keywords and hashtags. Misinformation on each platform was compared by manually coding and comparing posts using the World Health Organization fact-check page to adjudicate accuracy of content. RESULTS Both platforms posted about the outbreak and transmission but posts on Sina Weibo were less likely to reference controversial topics such as the World Health Organization and death and more likely to cite themes of resisting, fighting, and cheering against the coronavirus. Misinformation constituted 1.1% of Twitter content and 0.3% of Weibo content. CONCLUSIONS Quantitative and qualitative analysis of content on both platforms points to cross-platform differences in public discourse surrounding the pandemic and informs potential countermeasures for online misinformation.

Epistemic media and critical knowledge about the self: Thinking about algorithms with Habermas

This article explores the ontology of personal knowledge that algorithms on digital media create by locating it on two axes: historical and theoretical. Digital platforms continue a long history of epistemic media—media forms and practices, which not only communicate knowledge, but also create knowledge. As epistemic media allowed a new way to know the world, they also facilitated a new way of knowing the self. This historical perspective also underscores a key difference of digital platforms from previous epistemic media: their exclusion of self-reflection from the creation of knowledge about the self. To evaluate the ramifications of that omission, I use Habermas’s theory of knowledge, which distinguishes critical knowledge from other types of knowledge, and sees it as corresponding with a human interest in emancipation. Critical knowledge about the self, as exemplified by psychoanalysis, must involve self-reflection. As the self gains critical knowledge, deciphering the conditions under which positivist and hermeneutic knowledges are valid, it is also able to transform them and expand its realm of freedom, or subjectivity. As digital media subverts this process by demoting self-reflection, it also undermines subjectivity.

Traditional labour relationships have been disrupted due to the digital platforms based businesses. This article aims on the one hand to share the consequences the sharing economy has generated for workers, and how MONDRAGON’s principles as one of the best examples of worker owned business group in the world, can be applied within the new digital era. On the other hand, this paper provides a literature review on how digital platforms can operate with fairer principles based on the framework that platform coops consist of. Last but not least, Mondragon University and The New School have set up a capacity building program on team entrepreneurship and an online incubation program that aims to support the creation of platform coops, whose results after two editions and future opportunities for research are shared.

TCP\IP protocol can be connected to various computer data networks in the world. This protocol increasingly exists and is needed so that many parties develop it to vote through this protocol. Voice Over Internet Protocol technology is the answer to that desire. This technology is able to convert analog voice (human voice) into data packets then through public internet data networks and private intranet data packets are passed, so that communication can occur. With VoIP communication costs can be reduced so that it can reduce investment costs and conversations (cost saving) or even up to 100% free. VoIP implementation can be done by designing a wireless VoIP network (cable) using 3CXSystemPhone software as a PBX. In this scientific work the software used is 3CXSystemPhone 11.0, where SIP is a VoIP server which is a freeware software, in its application only requires one PC server and several PC clients (2 for example) that are connected to each other
