This document provides an overview of IPv4 addressing and wireless networking concepts. It discusses IPv4 address classes and valid/invalid addresses as examples. It also compares wired and wireless networks, outlining advantages and disadvantages of each, and factors that affect their performance such as interference, channel congestion, and number of users. Additional sections cover wireless site surveying, firmware options for routers, and best practices for channel allocation in wireless networks.

4. Endereçamento IPv4
• IPv4: endereços com 4 octetos. Ex.: 192.168.0.1
• Divididos em duas partes: Network ID e Host ID
• Classificação: Classes A, B, C, D e E.
Classe A: 001.x.x.x a 126.x.x.x – Redes de grande porte
Classe B: 128.1.x.x a 191.254.x.x – Redes de médio porte
Classe C: 192.0.1.x a 223.255.254.x – Redes de pequeno porte
Classe D: 224.x.x.x a 239.255.255.255 – Multicasting (áudio/vídeo simultâneo)
Classe E: 240.x.x.x a 247.255.255.255 – Uso reservado
• Reservas IANA para redes privadas:
10.x.x.x
172.16.x.x - 172.31.x.x
192.168.x.x

5. Endereçamento IPv4: exemplos
Endereços válidos:
10.1.0.1 a 10.1.0.254
10.0.0.1 a 10.0.0.254
10.0.1.1 a 10.0.1.254
192.168.0.1 a 192.168.0.254
192.168.1.1 a 192.168.1.254
Endereços inválidos:
10.1.0.0 – Host IP não pode ser 0
10.1.0.255 – Host IP não pode ser 255
10.123.255.4 – Nenhuma rede ou subrede pode usar 255
0.12.16.89 – Nenhuma rede Classe A pode começar com 0
255.9.56.45 – Nenhum endereço de rede pode começar com 255
Padrões de endereçamento mais comuns (roteadores):
192.168.0.1 – 192.168.1.1 – 192.168.254.1 – 10.0.0.1

6. Wired ou wireless? Com ou sem fio?
Wired Networks
Redes cabeadas
Vantagens e
desvantagens
Facilidade de instalação Instalações simples em novos espaços ou
retrofit. Normalmente complexas em locais já
prontos, edificações antigas, imóveis
tombados.
Custo total Baixo em instalações novas e retrofits,
variável em locais prontos (tende a alto por
material e mão de obra). Equipamentos e
cabos custam pouco hoje.
Confiabilidade Excelente. Atenção para conectores,
interferência com rede elétrica e
principalmente qualidade do material
empregado.
Performance Excelente. Em redes Ethernet Gigabit, 80
MBPS x 125 teóricos.
Segurança Boa. Limitada a vulnerabilidades físicas e/ou
dos servidores e clientes. Firewalls e outras
medidas de segurança são obrigatórias.

7. Wired ou wireless? Com ou sem fio?
Wireless Networks
Redes sem fio
Vantagens e
desvantagens
Facilidade de instalação Simples nas redes pequenas, sem backbone ou com
backbones simples. Complexa em redes maiores ou
com backbones mais extensos. ALTERNATIVA:
POWERLINE/WDS/BRIDGING
Custo total Normalmente baixo, mas depende diretamente da
quantidade de pontos e necessidade de backbone.
Equipamentos custam mais.
Confiabilidade Boa. Fatores cruciais: boa cobertura, alocação de
canais, quantidade de usuários, banda utilizada.
Pode variar com novas condições.
Performance Boa. Atinge cerca de 60% do teórico, mas cai com a
distância. Fatores cruciais: boa cobertura, alocação
de canais, quantidade de usuários, banda utilizada.
Pode variar com novas condições.
Segurança Cuidado! Protocolos de segurança wireless, hidden
SSID, administração do router e segurança do
backbone são obrigatórios.

8. Fatores que afetam a
performance de redes cabeadas
Conexão do NIC com o sistema
Limitações no processamento
Eficiência do HDD
Contenção do Bus
Eficiência da aplicação (FTP vs. SMB/CIFS, etc)
Tamanho do frame
Compressão (hardware e software)
Congestionamento do buffer
Capacidade da estrutura de rede, arquitetura, etc.
Exemplo de ferramenta de análise: NetCPS para PCs

9. Fatores que afetam a
performance de redes wireless
Os mesmos das redes cabeadas, mas também...
• Interferência com outros equipamentos
• Canais congestionados
• Quantidade de usuários
• Protocolo de segurança escolhido (ou não)
• Design do transmissor e antenas
• Adoção de antenas diferentes
• Posicionamento
• Firmware

10. Software/hardware de análise wireless
Ferramentas de análise de rede wireless:
• inSSIDer for Home (PC/Linux, Mac,
Android)
www.metageek.net/products/inssider
• NetStumbler (PC)
www.netstumbler.com/downloads/
• Access Agility Wi-Fi Scanner

12. Configurando roteadores wireless
Configurações
Essenciais:
Configurações
Opcionais:
 Checagem da conexão
física
 Definição do endereço
entregue (DHCP ativo?)
 (Re) definição do
endereço de acesso
 Redefinição admin/senha
 Ajuste do tipo de
conexão (ADSL, cabo)
 Definição do SSID
 Ajuste do protocolo de
segurança.
 SSID exibir/não exibir
 Habilitar/desabilitar
DHCP
 SSID adicionais
 WDS
 DMZ
 Redirecionamento
/abertura de portas
 MACs permitidos, QoS,
Tunneling (VPN,
Proxies)

13. Distribuindo endereços IP
• Descobrir e/ou definir endereço IP do roteador
(mudar ou não?)
• Definir endereços IPs fixos para os clientes que
podem ser administrados (preferência sequencial)
• Opcionalmente definir IPs fixos para os clientes que
não podem ser administrados
• Definir faixa de distribuição DHCP para os clientes
não administrados e visitantes
• Criar links para administração rápida dos clientes
administráveis

14. Firmwares alternativos
DD-WRT, Tomato, Open-WRT, etc.
(para roteadores com designs Broadcom ou Atheros)
 Altamente customizáveis
 Versões “mini” para roteadores com 2MB de flash ROM
 Versões específicas para ponto de acesso comercial, VOIP, etc.
 Vários idiomas
 DNS dinâmico / Acesso remoto
 Redes Wi-Fi virtuais
 NTP
 Ajuste de potência de saída (0-251mW, padrão de 28mW, 100mW
ideal/seguro)
 Status de uso (tempo, clientes, etc.)
 Wireless site surveying
 Monitoramento de tráfego e recursos
 QoS (Qualidade de Serviço)
 VoIP

15. Firmwares alternativos

16. Firmwares alternativos

17. Firmwares alternativos

18. Canalização Wi-Fi
•Canais sem sobreposição: 1, 6 e 11 (14 no Japão, quando houver)
•Ao usar vários pontos, escolher canais diferentes
•Fazer surveying para fugir do “canal 6 padrão”
•Cuidado ao usar 12,13 e 14
•Roaming: Exatamente o mesmo SSID, mesmo protocolo de segurança e senha, canais
diferentes conforme projeto

19. Canalização Wi-Fi b, g, n

20. Canalização Wi-Fi ac
