Virtual Access Point (VAP)
Virtual AP technology multiplies the number of Access Points present within the RF
footprint of a single physical access device. With Virtual AP technology, WLAN users
within the device’s footprint can associate with what appears to be different access points
and their associated 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.
