A Cognitive Radio concept using frequency hopping in the frequency range of 100 megahertz to 7.5 gigahertz has been announced by Radio Technology Systems. So far it is the first radio to cover this extended range and is supposed to achieve 400Mbps over this frequency range.

Spectrum Bridge is a pioneer in the use of a database designed to mitigate interference in the white spaces spectrum. This is one of the first steps in establishing the IEEE802.22 technology.Spectrum Bridge is one of 10 database providers approved by FCC and has asked them to certify its database.What is a White Space?White space is the basis Dynamic Spectrum Access and Cognive Radio architectures and has been studied by Wireless Spectrum Forum since 1996. A white space is a temporary or permanent hole in the frequency spectrum that can be used by a cognitive radio application. This concept was authorized by FCC to improve spectrum utilization.Read more here. October 2, 2012Santa Clara, CA - Agilent Technologies Inc. recently announced that STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, has selected Agilent's Electromagnetic Professional (EMPro) software for use in development of ESD structures based on advanced CMOS process technology.http://www.semiconductoronline.com/doc.mvc/agilent-technologies-simulation-software-selected-stmicroelectronics-0001 http://4g-portal.com/xg-technology-receives-fcc-certification-for-its-cognitive-radio-networking-equipment A Nokia anunciou ontem o lancamento de uma belezinha chamada 6136. Merece um post so pra ele porque trata-se de um telefone celular que permite dono fazer chamadas via internet.Funciona mais ou menos como um laptop com placa Wi-fi. Quando voce estiver em algum local com rede Wi-fi funcionando, o 6136 se conecta a internet e faz ligacoes como se estivesse usando um servico de Voz sobre IP (VoIP), como o conhecido Skype.O que significa isso tudo? Uma conta beeeem menor no final do mes. Nem precisava, mas ele vem equipado tambem com uma camera digital de 1.3 megapixel, zoom digital de 8x, slot de cartao de memoria e conexao Bluetooth.A ma noticia e que por enquanto ele deve ser lancado so no mercado europeu, a US$ 330 no segundo semestre. Mashable Mais uma dos nossos amigos japoneses (e o que nao seria do mundo dos gadgets e das noticias sem pe nem cabeca se nao existissem os japoneses, nao e minha gente?).A mania desse povo com a tecnologia ja esta chegando a niveis um pouco bizarros. E que os celulares com camera se tornaram itens obrigatorios em funerais no Japao. Os adeptos dizem
