What is 802.11X? standards confusion

Hi Mario,

I am Todd. Here I am giving you the solution of your question. Hope it will clear your confusion. I Will give you a brief overview of each standard and a comparison of each standard.

• First of all we see what is 802.11x exactly?

A wireless LAN is one, in which a mobile user can connect to a local area network (LAN), through a wireless (radio) connection. A standard, IEEE 802.11, specifies the technologies for wireless LANs.

• Which are different main  802.11 standards use?

Wireless LAN standards are defined by the IEEE's 802.11 working group. WLANs come in three flavors:

• 802.11b

  • Operates in the 2.4000 GHz to 2.2835GHz frequency range and can operate at up to 11 megabits per second.

• 802.11a

  • Operates in the 5.15-5.35GHz to 5.725-5.825GHz frequency range and can operate at up to 54 mega bits per second.

• 802.11g

  • Operates in the 2.4GHz frequency range (increased bandwidth range) and can operate at up to 54 megabits per second.

  • Comparison between all three standards
