Research paper thumbnail of Wireless data communications using DECT air interface

Computer Communication Review, 1999

In addition to the well-established voice service, it supports data communications. DECT currently addresses low bit rates, but additional modulation options have recently been included for high-speed, up to 2Mbps. In this paper, we describe the hardware and software design of an entire wireless communications system to be used in SOHO applications. While putting the emphasis on data communication, we demonstrate the feasibility of maintaining the compatibility with existent voice terminals. We developed generic hardware and software components, which revealed a very flexible approach. We easily created a wireless LANs, extended an Ethernet LAN and provided access to ISDN 1 .

O tratamento aqui desenvolvido em relação a O Caso Wagner encontra-se problematizado por um cruzamento com O Nascimento da Tragédia (1872), levando em conta a importância não apenas do tornar-se quem se é para Nietzsche mas, também, do tornar-se dos escritos, ou seja, como O Caso Wagner pode ser visto sob um outro ângulo quando colocamos em questão a sua obra de juventude. O foco estará na crítica que o filósofo faz a Wagner, porém, considerando que "Wagner" tenha sido escolhido ironicamente como o cenário que Nietzsche utiliza para tratar de um problema que diagnosticaria desde seus primeiros escritos: a decadência de uma cultura, precisamente, a alemã. A partir daí, pretende mostrar como em Nietzsche um problema de arte, ou seja, do âmbito do criar, não pode ser pensado separadamente de um problema de décadence. Palavras-chave: Arte, Décadence, Tornar-se, Nietzsche, Wagner.
