Enabling Wireless LANs (WLANs)
A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the
functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight
transmission, and are thus, desirable. Within the WLAN, roaming users can be handed off from one
Altitude 35xx to another like a cellular phone system. WLANs can therefore be configured around the
needs of specific groups of users, even when they are not in physical proximity.
Use the Altitude 35xx’s Wireless Configuration screen to create new WLANs, edit the properties of
existing WLANs or delete a WLAN to create space for a new WLAN. Sixteen WLANs are available on
the access point (regardless of single or dual-radio model).
