2-2 Wireless LAN Network
To connect to a wired network within a coverage area using Access Points (APs), set the G-162 operation
mode to Infrastructure (BSS). An AP acts as a bridge between the wireless stations and the wired
network. In case you do not wish to connect to a wired network, but prefer to set up a small independent
wireless workgroup without an AP, use the Ad-hoc (IBSS) (Independent Basic Service Set) mode.
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless stations communicate
directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service
Set (IBSS).
Figure 2-1 IBSS Example
To set up an ad-hoc network, configure all wireless stations in ad-hoc network
type and use the same SSID and channel.
Infrastructure (BSS)
When a number of wireless stations are connected using a single AP, you have a Basic Service Set (BSS).
Figure 2-2 BSS Example
A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set
(ESS) or infrastructure network. All communication is done through the AP, which relays data packets to
