Chapter 1 - Introduction
1.±.3 Roaming Between ASUS APs
If there are multiple ASUS APs on the network, then a wireless mobile client
may seamlessly roam from one ASUS AP to another.
Each ASUS AP creates its own wireless cell or coverage area. This is
also known as a Basic Service Set (BSS). Any wireless mobile client can
communicate with a particular ASUS AP if it is within the ASUS AP’s
coverage area.
If the cells of multiple ASUS APs overlap, then the wireless mobile client
may switch from one ASUS AP to another as it travels throughout the
facility. During the hand-off from one ASUS AP to another, the wireless
mobile client maintains an uninterrupted connection to the network. This
is known as “roaming.”
Multiple ASUS APs connected to a common Ethernet network form an
Extended Service Set (ESS). All members of an Extended Service Set are
configured with an ID, known as the SSID or ESSID. Wireless mobile clients
must be configured with the same SSID as the ASUS APs on the network. A
client can only roam between ASUS APs that share the same SSID.
1.±.± Roaming Guidelines
•
An ASUS WLAN Card can only roam between APs of the same type.
•
All ASUS APs must have the same SSID.
•
All computers with ASUS WLAN Cards must have the same SSID as
the Access Points that they will roam.
•
If WEP encryption is enabled, then all ASUS APs and client adapters
must use the same encryption level and WEP Key(s) to communicate.
•
The ASUS APs’ cells must overlap to ensure that there are no gaps
in coverage and to ensure that the roaming client will always have a
connection available.
•
ASUS APs that use the same Channel should be installed as far away
from each other as possible to reduce potential interference.
•
It is strongly recommended that you perform a site survey using the utility
provided with the ASUS WLAN Card to determine the best location for
each ASUS AP in the facility.
