Wireless VLAN (Multi-SSID)
VLAN stands for virtual LAN. It is a network structure with all
the characteristics of a normal LAN, but not geographically
constrained.
Based on the SSID, two or more clients can be added into
a VLAN and integrated into a LAN independently of their
geographical location. Without the use of routers, a level 2
switch, in conjunction with Weidmüller WLAN access points,
can distinguish broadcast domains from each other. In this
way, VLANs offer administrators exibility regarding network
security, network management and scalability.
WMM for prioritising communications
Quality of Service (QoS) is a network term for controlling
and measuring data transmission rates, throughput and error
rates. It is an essential part of wireless communication when
transmitting multimedia data like audio and video. Critical
data, for example, requires a high priority with respect
to the data throughput and low error rates. WMM (Wi-Fi
multimedia) is based on the IEEE 802.11e protocol which
was designed to integrate QoS functionality into a WLAN.
The advantages lie in the prioritising of important data and
the associated improvement of the communication quality.
