Controller, Access Points and Convergence Software terms and abbreviations
Data Collector
The Data Collector is an application on the HiPath Wireless Controller
that receives and manages the Radio Frequency (RF) scan
messages sent by the Wireless AP. This application is part of the
Mitigator technique, working in conjunction with the scanner
mechanism and the Analysis Engine to assist in detecting rogue
access points.
Virtual Network
Services (VNS)
The Virtual Network Services (VNS) technique is Siemens's means
of mapping wireless networks to the topology of an existing wired
network. When you set up Virtual Network Services (VNS) on the
HiPath Wireless Controller, you are defining subnets for groups of
wireless users. This VNS definition creates a virtual IP subnet where
the HiPath Wireless Controller acts as a default gateway for wireless
devices. This technique enables policies and authentication to be
applied to the groups of wireless users on a VNS, as well as the
collecting of accounting information. When a VNS is set up on the
HiPath Wireless Controller, one or more Wireless APs (by radio) are
associated with it. A range of IP addresses is set aside for the HiPath
Wireless Controller's DHCP server to assign to wireless devices.
Wireless AP
The Wireless AP is a wireless LAN thin access point (IEEE 802.11)
provided with unique software that allows it to communicate only with
a HiPath Wireless Controller. (A thin access point handles the radio
frequency (RF) communication but relies on a controller to handle
WLAN elements such as authentication.) The Wireless AP also
provides local processing such as encryption. The Wireless AP is a
dual-band access point, with both 802.11a and 802.11b/g radios.
