ASUS 802.11g WL-HDD2.5 7
You can configure the data rates used by the ASUS WL-HDD2.5 to
improve the performance. However, if you limit the range of data
rates available to the ASUS WL-HDD2.5, you may reduce the effec-
tive wireless range of the WLAN coverage.
Site Surveys
A site survey (utility provided with ASUS WLAN cards) analyzes the
installation environment and provides users with recommendations
for equipment and its placement. The optimum placement differs
depending on the ASUS AP design and specifications.
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 through-
out the building. 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.
