Wi-Fi Wireless Networks and Technology

Wi-Fi is the pre-eminent technology for building wireless networks. The term Wi-Fi stands
for Wireless-Fedelity which is the industrial name for wireless LAN communication technology related to the IEEE 802.11 family of wireless networking standards.




The wireless standards defined by IEEE are:
------------------------------------------------------
1. 802.11a

2. 802.11b

3. 802.11g


Compatibility
-------------------------

The standard 802.11a is not compatible with the other two. This compatibility issue is the major problem the Wi-Fi related instruments suffer.

Reason :

The wireless standards 802.11b and 802.11g are using the same frequency while 802.11a has different frequency.

Frequencies supports the wireless standards:


1. 802.11a ---5.2 GHz

2. 802.11b ---2.4 GHz

3. 802.11g ---2.4 GHz
