Internet das Coisas

Internet of Things - IoT

Ficção: máquinas, robôs, dispositivos,... comunicando entre si e tomando decisões para aumentar o conforto da humanidade.

Realidade: máquinas, robôs, dispositivos,... comunicando entre si e otimizando processos e inferindo informações com menos interferência humana.

Desafios encontrados na concepção da coisa (o produto):

  1. Inovação. É a mola mestra do futuro presente. Criar não é uma tarefa fácil. Inventar sempre terá como precursora a problemática. Não se inventa apenas por inventar... é preciso se antenar com problemas e necessidades da humanidade. Pensamento crítico é imperioso aos criadores.
  2. Ética. A "coisa" tem que se encaixar nos padrões admissíveis à época e não permitir desvios de conduta no seu uso. Mas pode apresentar novos conceitos e modos de se fazer.
  3. Crescimento. Buscar o bem comum e o crescimento da humanidade, permitindo o compartilhamento de recursos e benefícios à toda população, independentemente da raça, do credo, das convicções políticas e da renda.
  4. Aplicar conhecimentos para desenvolvimento de novas teorias e costumes saudáveis.

Desafios encontrados nos projetos de IoT:

  1. Seleção do módulo de comunicação sem fio. Na grande maioria dos projetos de IoT os dispositivos estarão conectados via comunicação sem fio (wireless). Qual padrão adotar? Qual padrão oferece a taxa de bits mínima necessária? A distância mínima necessária? Com menor potência possível, ou com maior autonomia de baterias?
  2. Projeto de RF e depuração. Dispositivos não estão funcionando? Analisando o domínio da frequência podemos identificar problemas que não podem ser vistos no domínio do tempo. Equipamentos e instrumentos adequados se fazem necessários na busca de soluções.
  3. Maximização da vida útil da bateria. Verifique se o seu dispositivo pode ter vida longa. Use as melhores práticas e certifique-se de preservar a vida da bateria a partir do projeto.
  4. Obtenção da pré-certificação EMI e EMC. O teste de avaliação EMI (EletroMagnetic Interference) é caro. Saiba como configurar pré-testes em seu laboratório para garantir o cumprimento da certificação já na primeira tentativa.
  5. Agilidade na geração de produto para o mercado. Use padrões estabelecidos de comunicação sem fio. De Bluetooth a WLAN, verifique se o produto cumpre as normas mais recentes. Garanta que o seu produto conseguirá o atalho para o mercado.
  6. Interferência das Coisas. Certifique-se de que o sinal do seu dispositivo poderá ser visto entre milhares de outros com o pré-trabalho (testes e ensaios) e as ferramentas adequadas.

    Hi this is kinda of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I'm starting a blog soon but have no coding knowledge so I wanted to get guidance from someone with experience. Any help would be enormously appreciated!

    Have you ever thought about writing an e-book or guest authoring on other blogs? I have a blog based upon on the same information you discuss and would really like to have you share some stories/information. I know my readers would value your work. If you're even remotely interested, feel free to send me an e-mail.

    This design is wicked! You certainly know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost...HaHa!) Fantastic job. I really enjoyed what you had to say, and more than that, how you presented it. Too cool!

    Whats up are using WordPress for your blog platform? I'm new to the blog world but I'm trying to get started and create my own. Do you require any coding expertise to make your own blog? Any help would be really appreciated!

    Hiya, I'm really glad I've found this information. Nowadays bloggers publish only about gossip and internet stuff and this is really annoying. A good web site with interesting content, that's what I need. Thanks for making this web site, and I'll be visiting again. Do you do newsletters by email?

    With havin so much content do you ever run into any problems of plagorism or copyright violation? My site has a lot of exclusive content I've either authored myself or outsourced but it seems a lot of it is popping it up all over the internet without my authorization. Do you know any methods to help stop content from being stolen? I'd definitely appreciate it.

    Superb blog! Do you have any suggestions for aspiring writers? I'm hoping to start my own blog soon but I'm a little lost on everything. Would you propose starting with a free platform like WordPress or go for a paid option? There are so many options out there that I'm completely overwhelmed .. Any suggestions? Bless you!

    Howdy would you mind sharing which blog platform you're working with? I'm looking to start my own blog in the near future but I'm having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I'm looking for something unique. P.S Sorry for being off-topic but I had to ask!
