Chapter 1: Product description 40
Channel estimation and sounding must be regularly repeated to ensure wireless network performance
remains high; the speed at which a system is able to accurately estimate the channel has a large impact on
performance.
Once channel estimation is completed for a wireless node, the MU-MIMO access point can electrically tune
each antenna to provide the highest performance for that node. The access point uses beamforming to
create a radio beam to that node which is tuned for optimum performance and avoids beams directed to
other nodes, reducing interference and helping to improve overall wireless network capacity.
A MU-MIMO access point can communicate to multiple wireless nodes simultaneously using this process.
As the majority of nodes are unable to make full use of the whole access point capacity at once,
communicating with several nodes simultaneously can greatly improve the overall capacity achieved in the
wireless network.

This section introduces the 450 Platform Family management system, including the web interface,
installation, configuration, alerts and upgrades.
Manag em ent ag ent
The 450 Platform Family radios are managed through an embedded management agent.
Management workstations, network management systems or PCs can be connected to this agent using
the module’s Ethernet port or over-the air (SM/BHS)
The management agent supports the following interfaces:
l
Hypertext transfer protocol (HTTP)
l
Hypertext transfer protocol secure (HTTPS)
l
RADIUS authentication
l
Simple network management protocol (SNMP) – v2c and v3
l
Network time protocol (NTP)
l
System logging (Syslog)
l
Wireless Manager (WM) software
l
Canopy Network Updater Tool (CNUT) software
l
cnMaestro™
W eb ser ver
The 450 Platform Family management agent contains a web server. The web server supports access via
the HTTP/HTTPS interface.
Web-based management offers a convenient way to manage the 450 Platform Family radios from a locally
connected computer or from a network management workstation connected through a management
network, without requiring any special management software. The web and SNMP are the interfaces
supported for installation of 450 Platform Family radios and for the majority of configuration management
tasks.
