Asus WL-HDD2.5 user manual Site Surveys, Roaming Between Asus APs

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.
