Chapter 9 Wireless LAN
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every device in the wireless network must have
the same key.
9.2.5 One-Touch Intelligent Security Technology (OTIST)
With ZyXEL’s OTIST, you set up the SSID and the encryption (WEP or WPA-PSK) on the
ZyXEL Device. Then, the ZyXEL Device transfers them to the devices in the wireless
networks. As a result, you do not have to set up the SSID and encryption on every device in
the wireless network.
The devices in the wireless network have to support OTIST, and they have to be in range of
the ZyXEL Device when you activate it. See
9.3 Wireless Performance Overview
The following sections introduce different ways to improve the performance of the wireless
network.
9.3.1 Quality of Service (QoS)
You can turn on Wi-Fi MultiMedia (WMM) QoS to improve the performance of voice and
video applications in the wireless network. QoS gives high priority to voice and video, which
makes them run more smoothly. Similarly, it gives low priority to many large file downloads
so that they do not reduce the quality of other applications.
9.4 Additional Wireless Terms
The following table describes wireless network terms and acronyms used in the ZyXEL
Device.
TERM
DESCRIPTION
RTS/CTS Threshold
In a wireless network which covers a large area, wireless devices are
sometimes not aware of each other’s presence. This may cause them to send
information to the AP at the same time and result in information colliding and
not getting through.
By setting this value lower than the default value, the wireless devices must
sometimes get permission to send information to the ZyXEL Device. The lower
the value, the more often the devices must get permission.
If this value is greater than the fragmentation threshold value (see below), then
wireless devices never have to get permission to send information to the
ZyXEL Device.
Preamble
A preamble affects the timing in your wireless network. There are two
preamble modes: long and short.
If a device uses a different preamble mode
than the ZyXEL Device does, it cannot communicate with the ZyXEL Device.
