Wireless LAN network defined by IEEE 802.11b/g standard committee 
could be configured as : 

 

Ad Hoc wireless LAN, 

or 

 

Infrastructure wireless LAN. 

 
Ad Hoc 

network is a group of PCs installed with wireless LAN cards, this 

group of PCs is called a BSS (Basic Service Set). PCs in this group can use 
their wireless LAN cards to communicate with each other, but can not 
connect to the 

Internet

 

Ad Hoc 

Wireless Network                 

Infrastructure 

Wireless Network 

 
The most obvious difference between 

Infrastructure 

wireless network 

and 

Ad Hoc 

wireless network is that the PCs in 

Infrastructure 

wireless 

network can access the resource in the Internet through 

Access Point

 
 

Depending on your requirement, you can easily set up your PC’s 

network to be a “

Ad Hoc

” or “

Infrastructure

” wireless network. Generally 

speaking, if in your network, there is an 

Access Point 

in it, we recommend 

you to set your network as an “

Infrastructure

”, so it can connect to 

the 

Internet
