Explanation
The DRM feature consists of software on the Wireless AP that
provides dynamic radio frequency (RF) management. For Wireless
APs with the DRM feature enabled and on a common channel, the
power levels will be adjusted to balance coverage if a Wireless AP is
added to, or leaves, the network. The feature also allows wireless
clients to be moved to another Wireless AP if the load is too high. The
feature can also be set to scan automatically for a channel, using a
channel selection algorithm.
The HiPath Wireless Controller is a rack-mountable network device
designed to be integrated into an existing wired Local Area Network
(LAN). It provides centralized control over all access points (both
Wireless APs and third-party access points) and manages the
network assignment of wireless device clients associating through
access points.
Langley is a Controller, Access Points and Convergence Software
term for the inter-process messaging infrastructure on the HiPath
Wireless Controller.
The Mitigator is a mechanism that assists in the detection of rogue
access points. The feature has three components: (1) a radio
frequency (RF) scanning task that runs on the Wireless AP, (2) an
application called the Data Collector on the HiPath Wireless
Controller that receives and manages the RF scan messages sent by
the Wireless AP, (3) an Analysis Engine on the HiPath Wireless
Controller that processes the scan data.
The technique in Controller, Access Points and Convergence
Software by which multiple HiPath Wireless Controllers on a network
can discover each other and exchange information about a client
session. This enables a wireless device user to roam seamlessly
between different Wireless APs on different HiPath Wireless
Controllers, to provide mobility to the wireless device user.
One HiPath Wireless Controller on the network must be designated
as the mobility manager. All other HiPath Wireless Controllers are
designated as mobility agents. Relying on SLP, the mobility manager
registers with the Directory Agent and the mobility agents discover
the location of the mobility manager.
