ZyXEL Communications NWA-3500 ユーザーズマニュアル

 Chapter 1 Introducing the NWA

NWA-3500/NWA-3550 User’s Guide

To the wireless clients in the network, each SSID appears to be a different access 
point. As in any wireless network, clients can associate only with the SSIDs for 
which they have the correct security settings.

For example, you might want to set up a wireless network in your office where 
Internet telephony (Voice over IP, or VoIP) users have priority. You also want a 
regular wireless network for standard users, as well as a ‘guest’ wireless network 
for visitors. In the following figure, VoIP_SSID users have Quality of Service 
(QoS) priority, SSID03 is the wireless network for standard users, and 
Guest_SSID is the wireless network for guest users. In this example, the guest 
user is forbidden access to the wired LAN behind the AP and can access only the 
Internet.

The NWA has two pre-configured SSID profiles. 

VoIP_SSID. This profile is intended for use by wireless clients requiring the 
highest QoS (Quality of Service) level for VoIP (Voice over IP) telephony and other 
applications requiring low latency. The QoS level of this profile is not user-
configurable. See 

 for more information on QoS.
