Proposta de uma rede de acesso banda larga sem fio rural padrão IEEE 802.16

Abstract

In recent years, the wireless network technologies of broadband access with integrated data, video and voice were limited in relation to distance, QoS (Quality of Service) and bandwidth, especially in areas whit lack of infrastructure and difficult access, such as rural. The IEEE 802.16 standard was created to provide broadband connectivity to wireless fixed and mobile users in a wide coverage area with high rates of data transfer, also seeking to address the barriers found in previous technologies, promising data transfer rates of up to 1 Gbps for fixed users and 100 Mbps for mobile users and QoS for those applications. This paper aims to highlight the IEEE 802.16 standard features and also to present a proposal for an wireless rural broadband network access IEEE 802.16 standard, designed to meet communication requirements of a rural community model. The planning allowed to define a rural community that will serve as a model for other communities with similar characteristics. The Site-Survey enabled the collecting of data and information needed to adequate coverage and to determine the amount of BSs needed to cover the specified area, and the mapping of demand to determine the SSs quantity. In terms of the highlighted SS s, the demand for bandwidth to meet the user applications in PBH (Peak Busy Hour) was mapped.
