Wireless Topology
This section will describe example applications of wireless topologies and their corresponding wireless parameter
settings for SW550X
.
Typically, IEEE 802
.
11 wireless network standards will support two wireless network
topologies
:
ad
-
hoc and infrastructure modes
.
In Ad Hoc mode, each wireless node will communicate directly with each other and have equal role in
communication in which they are usually called peer
.
On the other hand, in infrastructure mode, there will be one or more access points which will control the network
and how other wireless nodes communicate with each other
.
Each wireless node will be called wireless client
.
In
Infrastructure mode, each wireless node cannot communicate directly with each other
.
They must communicate
via the access point only
.
We can configure SW550X as a wireless ad
-
hoc peer or a wireless client in infrastructure mode
.
Note that SW550X
cannot be operated as an access point in infrastructure mode
.
If you require an access point, please consider a
deployment of Atop
’
s AW5500 series
.
Atop recommends the user to utilize the strongest wireless security measure
as described in the following subsections
.
5.3.1
Configure SW550X as a Wireless Ad-Hoc Peer
To configure SW550X as an ad
-
hoc peer, please click on Basic Settings
page under the Wireless menu and follow
steps in Paragraph 4.2.1 above
shows an example of a wireless ad

with open authentication and no encryption
.
However, Atop recommends that you should enable the security
mechanism using the Wire

(
WEP
)
