GO Wireless Network Controller (WNC)
The Wireless Network Controller (WNC) is a high-performance server/controller that
provides functionality such as:
• Inter-base station optimization
• Fast roaming between base stations
• Access to controller functionality,
including user authentication
• Quality-of-Service (QoS) provisioning
per user or user profile
• Centralized interface for management and billing systems.
The Wireless Network Controller connects between the operator backbone/Internet
traffic and signaling and the WLAN access (typically a WLAN Sector Base Station). All
traffic passes through the Wireless Network Controller either on its way to the
Internet or from the Internet to the station (via the local WLAN Sector Base Station)
Wireless Network Controller offers global spectrum management and is carries
central responsibility for dynamically managing the network for optimal system
performance. In addition, the Wireless Network Controller is responsible for
determining whether a station should “roam” to another WLAN Sector Base Station in
the system.
Deployment Options
The Wireless Network Controller can be deployed in one of the following ways:
• In-line Traffic: Provides global spectrum management and load balancing of
stations between WLAN Sector Base Stations and between channels within the
WLAN Sector Base Stations. All Internet-bound traffic is routed through the WNC.
• Non In-line Traffic: Global Spectrum management and users’ load balancing
between WLAN Sector Base Stations/Channels.
The deployment process involves first indoor components of the system, followed by
the outdoor installation of the WLS unit on a pole or rooftop wall. Installation and
configuration of both the WNC and the WLS are detailed in the following sections.
