1. Wi-Fi Standards
   1. IEEE 802.11
      1. Deprecated. The original standard (1997)
      2. 2 Mbps (max)
      3. DSSS
      4. FHSS
   2. IEEE 802.11b

2. Modulation:
   1. Spread Spectrum
      1. A signal generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth.
      2. DSSS
         1. Direct-Sequence Spread Spectrum
      3. FHSS
         1. Frequency-Hopping Spread Spectrum
   2. OFDM
      1. Orthogonal Frequency-Division Multiplexing
   3. MIMO
      1. Multiple Input, Multiple Output
3. Encryption:
   1. WEP
      1. Wired Equivalent Privacy
         1. Easily Hacked. Do not use.
   2. WPA
      1. Wi-Fi Protected Access
         1. Use over WEP. Use WPA2 if available.
         2. Uses TKIP:
            1. Temporal Key Integrity Protocol
   3. WPA2
      1. Wi-Fi Protected Access Version 2
         1. Upgraded WPA. Use this.
         2. Uses CCMP:
            1. Counter Mode Cipher Block Chaining Message Authentication Code Protocol
            2. Based on AES
4. Tools:
   1. Aircrack-ng
   2. Fern
