Privacy

Privacy is a mechanism that protects data over wireless and wired networks, usually by
encryption techniques.
Controller, Access Points and Convergence Software supports the Wired Equivalent Privacy
(WEP) standard common to conventional access points.
It also provides Wi-Fi Protected Access version 1 (WPA v.1) encryption, based on Pairwise
Master Key (PMK) and Temporal Key Integrity Protocol (TKIP). The most secure encryption
mechanism is WPA version 2, using Advanced Encryption Standard (AES).

Virtual Network Services

Virtual Network Services (VNS) provide a versatile method of mapping wireless networks to the
topology of an existing wired network.
When you set up VNS on the HiPath Wireless Controller you are defining subnets for groups of
wireless users. The VNS definition provides the binding between VNS IP topology configuration
(Routing, DHCP policy) and the RF configuration parameters that advertise and control
network access (SSID, Privacy policy: WEP and WPA). 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 on user sessions that can be used for billing.
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
If routing protocol is enabled, the HiPath Wireless Controller advertises the VNS as a routable
network segment to the wired network and routes traffic between the wireless devices and the
wired network. The HiPath Wireless Controller C2400 also supports VLAN-bridged assignment
for VNSs. This allows the controller to directly bridge the set of wireless devices associated with
a VNS directly to a specified core VLAN.
The HiPath Wireless Controller C2400 can support up to 64 VNSs.
Controller C1000 can support up to 50 VNSs, the C100 can support up to 32 VNSs, and the
C10 can support up to 16.
a system. Each AP can be the subject of 8 VNS assignments (corresponding to the number of
SSIDs it can support). Once a radio has all 8 slots assigned, it is no longer eligible for further
assignment.
