Enhanced Location Services
AOS-W 2.2 adds more precise position tracking of wireless devices by utilizing
RF triangulation. In previous AOS-W releases, the “RF Locate” feature would
display the nearest APs receiving signals from a wireless user or AP, along
with the corresponding signal strength. AOS-W 2.2 adds the ability to
triangulate position based on RF signal strength. This algorithm is accurate to
within approximately 10 meters. Note that for triangulation to function
properly, at least three sources of data are required. If three sources of data
are not available, the system will revert to showing the nearest APs receiving
signal from the device to be located. An additional restriction on triangulation
in release 2.2 is that APs must be present in the network in order to provide
live calibration data – triangulation will not function in a network with only air
monitors in this release.
Web Management Interface Enhancements
Many sections of the Web-based management interface have been changed to
improve usability. In addition, all critical features configurable from the CLI are
also now available in the Web interface.
Enhanced Network Monitoring Interface
The “Monitoring” section of the Web-based management interface has been
enhanced through the separation of network monitoring and switch
monitoring. In a network with multiple Alcatel switches, the network
monitoring section now provides an easy interface into the network view of
the system. When connected to the master switch, all users in the entire
network can now be located from the network monitoring section.
SNMPv3
Previous releases of AOS-W supported only SNMPv1 and SNMPv2c. When
connecting Alcatel components to a network management platform across an
insecure network, use of these protocols could lead to unintentional releases
of sensitive information. SNMPv3 provides the ability to encrypt SNMP
communication.
Remote Thin AP
Some customers reported problems when using Alcatel APs connected to a
switch across a low-speed link such as a frame relay connection. The issue
with this was that latency in the low-speed link would cause greater than 5ms
of delay when responding to 802.11 probe request frames from wireless
clients. Certain clients would only wait on a single channel for 5ms, and would
be on a new channel by the time the probe response arrived. AOS-W 2.2
