12 ASUS SpaceLink 802.11g Access Point
Access Point will not forward the packet to the wireless mobile clients.
The SpaceLink 802.11g Access Point applies the same principles to
determine if a packet received over its radio should be forwarded to the
Ethernet network.
The SpaceLink 802.11g Access Point forwards all broadcast packets to
wireless mobile clients. Given this, the SpaceLink 802.11g Access Point
can only support a limited amount of network traffic. It is recommended
that you only use the SpaceLink 802.11g Access Point on networks that
contain less than 512 nodes.
The number of wireless mobile clients that can be supported by the
SpaceLink 802.11g Access Point depends on the amount of information
that each client exchanges with the network. Therefore, the number of clients
that can be supported by one SpaceLink 802.11g Access Point will vary
based on the applications in use and how frequently network information
is accessed.
Roaming Between SpaceLink Access Points
If there are multiple SpaceLink Access Points on the network, then a wireless
mobile client may seamlessly roam from one SpaceLink 802.11g Access
Point to another.
Each SpaceLink 802.11g Access Point 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 SpaceLink 802.11g Access
Point if it is within the SpaceLink Access Point’s coverage area.
If the cells of multiple SpaceLink Access Points overlap, then the wireless
mobile client may switch from one SpaceLink 802.11g Access Point to
another as it travels throughout the facility. During the hand-off from one
SpaceLink 802.11g Access Point to another, the wireless mobile client
maintains an uninterrupted connection to the network. This is known as
“roaming.”
Multiple SpaceLink Access Points 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 SpaceLink
Access Points on the network; a client can only roam between SpaceLink
Access Points that share the same SSID.
