Wireless Network Configurations
There are three basic RoamAbout wireless network configurations:
• One or more APs connecting wireless clients to a wired network, using the workgroup
bridge mode. A wireless client can be any computer with an 802.11 Direct-Sequence
(DS) compliant radio card. This type of network is referred to as a wireless
infrastructure network.
• Two or more APs used as a wireless link connecting wired networks. This is called a
LAN-to-LAN configuration. There are two variations of the RoamAbout LAN-to-LAN
configurations:
— Point-to-point which connects two wired networks, using the LAN-to-LAN
endpoint bridge mode.
— Point-to-multipoint which can connect multiple wired networks, using the
LAN-to-LAN multipoint bridge mode.
• Wireless clients communicating among themselves without a connection to a wired
network. This is called a peer-to-peer or ad-hoc network.
