Quick overview of the 802.11 standards

Sometimes I need for wireless network designs the frequency, range, speed and channels, therefore I put a quick overview of the 802.11 standards based on Wikipedia’s IEEE 802.11 article on my website.

Quick overview of 802.11 standards
  • DSF: Dynamic Frequency Selection
  • TPC: Transmit Power Control
  • SRD: Short Range Devices

Note: The 2.4 GHz is the worst range possible. In my neighborhood I have over 50 2.4 GHz wireless networks in range, so I disabled 2.4 GHz on my wireless controller.
