2.4.2 Site survey

A site survey (utility provided with the ASUS Pocket Wireless AP) analyzes the installation environment and provides users with recommendations for equipment and its placement. The optimum placement differ depending on the device design and specifications.

2.5Roaming information

If there are several ASUS Pocket Wireless APs operating on a network, then a wireless client (such as Centrino notebooks or wireless PDAs) may seamlessly roam from one ASUS Pocket Wireless AP to another. Each ASUS Pocket Wireless AP creates its own wireless cell or coverage area known as a Basic Service Set (BSS). Any wireless client can communicate with a particular ASUS AP if it is within that AP’s coverage area.

If the cells of multiple ASUS Pocket APs overlap, then the wireless client may switch from one ASUS Pocket Wireless AP to another. During the transfer from one ASUS AP to another, the wireless mobile client maintains an uninterrupted connection to the network. This is called roaming.

Multiple ASUS Pocket 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 clients must be configured with the same SSID as that of the ASUS Pocket APs on the network since it can only roam between ASUS Pocket APs sharing the same SSID.

Important notes on roaming

•An ASUS WLAN card can only roam between APs of the same type.

•All ASUS Pocket Wireless APs must have the same SSID.

•All computers with ASUS WLAN cards must have the same SSID as the access points to enable roaming.

•If encryption is enabled, all ASUS APs and wireless clients must use the same encryption to establish connection.

•ASUS Pocket Wireless APs’ cells must overlap to provide an uninterrupted connection for a roaming client.

•ASUS Pocket Wireless APs using the same channel should be installed away from each other to reduce potential interference.

•We strongly recommended that you perform a site survey using the ASUS Pocket Wireless AP utility to determine the best location for each wireless device.
