Study Notes

Wireless Networking Basics

  • Two methods for connecting computers to a network: wired and wireless
  • Wired connection uses LAN/UTP cables
  • Wireless connection transmits data through electromagnetic waves

Frequency Spectrum

  • Earth is surrounded by electromagnetic fields (EMF)
  • Wave characteristics vary with force (lower force = lower frequency waves, higher force = higher frequency waves)
  • WLANs use the radio spectrum, specifically 2.4 GHz and 5 GHz bands

2.4 GHz and 5 GHz Bands

  • 2.4 GHz band uses 802.11 standard
  • Channel separation and interchannel interference is important in 2.4 GHz
  • 5 GHz band uses 802.11a standard
  • Non-overlapping channels are present

Securing Wireless Networks

  • Wireless data is vulnerable to interception by rogue devices
  • Security is achieved through authentication, encryption, and data integrity

Authentication

  • 3-stage authentication process: challenge, response, validation
  • Common authentication methods include 802.1x authentication process and 802.11 standard authentication methods

Encryption

  • Encryption methods, like TKIP, RC4 cipher, Michael algorithm, CCMP, AES, CBC-MAC, GCMP, and GMAC, are used to protect data
  • WPA uses TKIP, WPA2 uses CCMP, and WPA3 uses GCMP

Implementing a Wireless Network

  • Wireless network uses radio frequencies for connections between nodes
  • Wireless Access Point (WAP) allows wireless-capable devices to connect to a wired network

Wireless Network Planning

  • Process of strategizing and architecting a wireless network design that provides adequate coverage, security, and capacity

Wireless Network Implementation

  • Necessary equipment includes a wireless router (used to broadcast the Wi-Fi signal) and an Ethernet cable to connect the router to a modem
  • Implementation steps include: physical setup, connection of router, and placement

Infrared and Bluetooth

  • Bluetooth allows short-range wireless communication between devices
  • Used in various personal electronic devices (keyboards, headsets, computers, etc.)
  • Infrared uses radiation with longer wavelengths than visible light, but shorter than microwaves
  • Used for remote controls and some other applications

Remote Connectivity Concepts

  • Remote connectivity is the ability of devices to connect remotely through internet or local networks
  • The telephone system is a primary example of remote connectivity, enabling communication between different locations
  • Protocols like Frame Relay, ATM, RAS, and PSTN are examples of remote connectivity technologies
  • Modem types, including external, internal, and multiline rack, are used for connecting to these networks
  • ISDN (Integrated Services Digital Network) provides various channels and services for these networks

Remote Connectivity Methods

  • Remote Desktop Protocol (RDP) is used for remote access to Windows-based systems
  • Virtual Network Computing (VNC) and SSH are alternatives to RDP
  • Cloud-based remote desktop services are also available

5G and Beyond

  • 5G offers ultra-fast speeds and low latency
  • Massive IoT applications are enabled by this technology

Artificial Intelligence (AI) and Machine Learning (ML)

  • AI and ML play a role in customer service and fraud detection in telecommunications

Internet of Things (IoT)

  • Advancement in interconnected devices, smart homes, and cities are present under the IoT category

Cloud Computing

  • Cloud computing facilitates scalability and flexibility

Terminal Service

  • Integrated into Windows operating system, providing terminal access to different systems
  • Terminal Services history includes mainframe era, PC revolution, and entry into Microsoft products like NT 3.51, NT 4.0, 2000, 2003, 2008, and Windows-based terminal (WBT)

Dial-up Networking

  • Connects to the internet via a standard telephone line

VPN (Virtual Private Network)

  • Network that uses public networks but creates a protected network connection for devices, encrypting the data
  • Provides secure remote access and provides protection during data transmission

Security Protocols

  • Various security protocols are used to secure network communication including IPSec, Secure Socket Tunneling Protocol (SSTP), WireGuard, OpenVPN, Point-to-Point Tunneling Protocol (PPTP), and Layer 2 Tunneling Protocol (L2TP)
