network services. All the services are delivered using a single radio channel, enabling Virtual AP
technology to optimize the use of limited WLAN radio spectrum.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision domain regardless of
their physical location or connection point in the network. A VLAN serves as a logical workgroup
with no physical barriers, and allows users to share information and resources as though located
on the same LAN.
Wi-Fi Protected Access
WPA employs 802.1X as its basic framework for user authentication and dynamic key
management to provide an enhanced security solution for 802.11 wireless networks.
Wired Equivalent Privacy (WEP)
WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless
devices without a valid WEP key will be excluded from network traffic.
WPA Pre-shared Key (PSK)
PSK can be used for small office networks that may not have the resources to configure and
maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared
password for network access.
