概述
The network infrastructures in the industrial and office areas are
coming ever-closer together. This applies also in the area of
无线通信，导致不断增加
访问点和WLAN客户端的数量。
如果建立了大量独立的网络
alone access points, with each one having to be configured
另外，这为初始配置和
手术。
Central wireless LAN controllers enable low-cost, user-friendly
and secure operation of large WLAN infrastructures here.
Management of the WLAN clients connected to such WLANs is
significantly simplified thanks to their division into user groups
with different security policies.
尺度WLC711 IWLAN控制器是用于
集中管理（配置，诊断，固件
updates, access control, security settings, coordination) of a
wireless LAN in the industrial environment.
•
快速建立新的WLAN或现有的扩展
wlan借助尺度W786C和
SCALANCE W788C controller-based access points
•
不同服务的并行操作（例如通信
在可编程控制器之间，互联网访问，
Voice-over-IP telephony and video transmission) on the same
controller-based WLAN infrastructure without requiring
为此目的其他SSID。
•
生产WLAN与公司之间的无缝过渡
WLAN
•
简化调试以及提高可靠性和
security thanks to the central management functions of the
IWLAN controller in comparison to a WLAN comprising stand-
单独的访问点必须单独配置
■
好处
•
减少调试结束head and operation of larger
IWLAN安装（最多48个访问点或96个访问
points in redundant mode) thanks to configuring from a central
地点
•
投资保护得益于无缝集成到
existing IWLAN installations or into an existing corporate
WLAN
•
节省冗余基础架构（例如
Internet access and voice transmission) thanks to multiple use
of the same infrastructure for different services
•
由于可选的平行，避免了单个失败点
operation of two controllers; the WLAN remains functional
即使控制器失败
•
通过操作IWLAN时，可靠性提高了
IWLAN控制器的完整，协调的投资组合
SCALANCE WLC711, industrial access points and
SCALANCE W client modules, as well as the suitable acces-
sor（天线，连接电缆，电源）
•
由于使用了网络的灵活配置
集成无线网状解决方案
•
Dynamic Radio Management supports the optimal alignment
整个WLAN网络
•
In the controller-based WLAN, the bandwidth or the
assignment of the access points can be automatically
受IWLAN控制器尺度WLC711的影响
depending on the requirements. This ensures optimal
utilization of the WLAN by the IWLAN client modules.
