User Deployed Hot-Spots in Rurual 5G Networks

Zaman, Nasir January 2019 (has links)
Cellular network expansion in rural areas has been traditionally slower than in dense urban areas. Area coverage in rural areas is fundamentally limited by the deployment cost for the operator. The 5th generation new radio (5G NR) network is designed to deliver unprecedented levels of capacity, high data rates, low latency and high reliability anytime and anywhere. The focus of 5G NR development is on relatively short-range communication using high frequency bands (e.g. mmWave-length) where lots of spectrum is available. For extremely long-range communication (e.g. in rural areas) high frequency bands are less suitable due to the high signal attenuation. One way to increase coverage in rural areas is to allow end users to deploy their own personal local hot-spot nodes that connect to the cellular network. A personal rural hot-spot can make use of higher transmission power and have better antennas than what normal user terminals can be equipped with. This thesis work will study the impacts of ”user deployed rural hot-spots” on the network like how much the network energy consumption can be decreased, what is the effect of discontinuation transmission (DTX) on network sleep mode and how inter site distance (ISD) can be increased to increase the coverage. One way to increase rural coverage by using the user deployed hot-spot is to reduce the network energy consumption for network operators and results show that by using user deployed hot-spots (enhanced UE) decreased the network energy consumption and while enhancing the BS configuration will require additional capital expense (CAPEX) investment for the network operators. User deployed hot-spot provide better connectivity for the users that are lying in network edges and helps to increase the inter site distance (ISD) of wireless networks.

RELAÇÕES COLABORATIVAS E REDES SOCIOPRODUTIVAS: UM ESTUDO SOBRE OS PRODUTORES DE VINHO ARTESANAL DO CHAPADÃO JAGUARI RS BRASIL / COLLABORATIVE RELATIONS AND SOCIO-PRODUCTIVE NETWORKS: A STUDY ABOUT ARTISANAL WINE PRODUCERS OF THE CHAPADÃO. JAGUARI RS

Venturini, Fernanda Elisa de Oliveira 26 August 2014 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The main objective of this research is to understand the process of structuring of the network socio productive of the family agricultural industries of the wines of Jaguari-RS, analyzing which elements provide the permanence of this network in time and space. The networks could from local actors or top down, starting with programs aimed at developing models. The misconceptions made in projects to encourage collective organizations, as in the case of a network of family agribusinesses, are very common, both in human resources and in public resources. In this sense, the research becomes important in rural communities, to recognize elements of sociability that serve to empowering relationships in other territories which in turn have productive affinities. The study methodology was qualitative. A case study was conducted with eleven producers of grape / wine, located in the locality of the Chapadão of that municipality. As a result we obtained the structure of socio-productive network in sociograms, showing the influence of the elements of sociability in the organization of the network in the socio-cultural and economic- financial dimensions. The research also proved that the set of elements, trust and reciprocity has the potential to support the socio-cultural dimension of the network, as well as the interest elements and interaction potentiated network formation in the economic and financial dimension. The results of this research could contribute to the work of agents of rural development, through the checking of the existing sociability among a certain group of farmers organized in network. / O objetivo dessa pesquisa é compreender o processo de estruturação da rede socioprodutiva das agroindústrias familiares de vinhos da localidade Chapadão - Jaguari-RS - Brasil, analisando quais os elementos que proporcionam a formação e sustentação desta rede no tempo e no espaço. A constituição de redes pode se dar partindo dos atores locais, ou de cima para baixo, a partir de programas de natureza governamental. Os equívocos em projetos de fomento a organizações coletivas, como uma rede de agricultores familiares, podem ser onerosos tanto em recursos humanos quanto em verba pública. Neste sentido, a pesquisa torna-se importante para reconhecer em comunidades rurais quais elementos constituem as bases de fortalecimento das relações sob as quais se sustentam atividades produtivas. A metodologia de estudo foi qualitativa. Foi realizado um estudo de caso junto à onze unidades de produção de uva/vinho situadas na localidade do Chapadão do referido município. Como resultados se obteve a estrutura da rede socioprodutiva em formato de sociogramas, mostrando a influência dos elementos de sociabilidade na organização da rede nas dimensões sociocultural e econômico - financeira. A pesquisa também comprovou que o conjunto de elementos, confiança e reciprocidade tem potencial de sustentação da rede na dimensão sociocultural, assim como os elementos interesse e interação potencializaram a formação da rede na dimensão econômico financeira. Considera-se que essa pesquisa pode vir a contribuir com o trabalho de mediação de agentes de desenvolvimento rural, através da verificação dos elementos de sociabilidade existentes, dentre um determinado grupo de agricultores organizados rede.
