Wi-Fi is the name of the standard wireless technology that employs radio waves, providing high-speed wireless Internet or network connections. Mobile phones, home networks, video games, and various other devices use it. Most personal computer operating systems (OSs) and many gaming consoles, printers, and peripherals sustain Wi-Fi today.

Wi-Fi offers convenience and lessens complexity in the process of wireless access to data, applications, media, and streams. Wi-Fi’s primary aims are to:

  • Provide easier information access
  • Ensure device compatibility
  • Reduce wiring and cables
  • Eliminate adapters, connectors, pins, plugs, and switches

A Wi-Fi enabled gaming console, mobile phone, MP3 player, PDA, or personal computer can link up to the Internet if it is within a wireless network’s range.

The main purpose of an access point is to transmit a wireless signal detected and ‘traversed’ by computers. Computers and other devices must have wireless network adapters to be able to connect to access points. One or more of these connected access points is called a hotspot. A hotspot can cover an area as large as several square miles or space as tiny as a small room.

Many Wi-Fi software tools are currently within reach. These Wi-Fi tools perform functions like:

  • Discovery of wireless networks
  • Mapping of wireless networks
  • Traffic analysis within wireless networks
  • Monitoring of RF strength within wireless networks
  • Encryption cracking of wireless networks
  • Custom-frame generation for wireless networks
  • Dictionary or ‘brute force’ attacks against wireless networks
  • Denial of Service (Dos) attacks against wireless networks

Various platforms can avail of the following Wi-Fi software tools:

  • Multiple platforms
  • Windows
  • Unix
  • Mac OS
