CHAPTER 1
Getting to Know Your G-560
This chapter introduces the main features and applications of the G-560.
1.1 Introducing the G-560 Wireless Access Point
The G-560 is an access point (AP) through which wireless stations can communicate and/or
access a wired network. It can also work as a bridge to extend your wireless network. The G560 uses IEEE 802.1x, WEP data encryption, WPA (Wi-Fi Protected Access), WPA2 and
MAC address filtering to give mobile users highly secured wireless connectivity. Both
IEEE802.11b and IEEE802.11g compliant wireless devices can associate with the G-560.
The G-560 is easy to install and configure.
1.2 G-560 Features
The following sections describe the features of the G-560.
Bridge
The G-560 can act as a bridge, establishing up to four wireless links with other APs.
WDS Functionality
A Distribution System (DS) is a wired connection between two or more APs, while a Wireless
Distribution System (WDS) is a wireless connection. Your G-560 supports WDS, providing a
cost-effective solution for wireless network expansion.
Figure 1 WDS Functionality Example
Chapter 1 Getting to Know Your G-56023
ZyXEL G-560 User’s Guide
OTIST (One-Touch Intelligent Security Technology)
OTIST allows your G-560 to assign its SSID and security settings (WEP or WPA-PSK) to the
ZyXEL wireless adapters that support OTIST and are within transmission range. The ZyXEL
wireless adapters must also have OTIST enabled.
This auto-negotiating feature allows the G-560 to detect the speed of incoming transmissions
and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
The LAN interface automatically adjusts to either a crossover or straight-through Ethernet
cable.
Reset Button
The G-560 reset button is built into the rear panel. Use this button to restore the factory default
password.
802.11g Wireless LAN Standard
The ZyXEL wireless products containing the letter "G" in the model name, such as G-560 and
G-162, comply with the IEEE 802.11g wireless standard.
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE
802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa)
at 11 Mbps or lower depending on range.
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences
between WPA and WEP are user authentication and improved data encryption.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption,
authentication and key management than WPA.
WMM (Wi-Fi MultiMedia) QoS (Quality of Service)
WMM QoS allows you to prioritize wireless traffic according to the delivery requirements of
the individual and applications.

ZyXEL G-560 User’s Guide
SSL Passthrough
The G-560 allows SSL connections to go through the G-560. SSL (Secure Sockets Layer)
uses a public key to encrypt data that's transmitted over an SSL connection. Both Netscape
Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain
confidential user information, such as credit card numbers. By convention, URLs that require
an SSL connection start with "https" instead of "http".
Wireless LAN MAC Address Filtering
Your G-560 checks the MAC address of the wireless station against a list of allowed or denied
MAC addresses.
WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.
IEEE 802.1x Network Security
The G-560 supports the IEEE 802.1x standard to enhance user authentication. Use the built-in
user profile database to authenticate up to 32 users using MD5 encryption. Use an EAPcompatible RADIUS (RFC2138, 2139 - Remote Authentication Dial In User Service) server
to authenticate a limitless number of users using EAP (Extensible Authentication Protocol).
EAP is an authentication protocol that supports multiple types of authentication.
Full Network Management
The embedded web configurator is an all-platform web-based utility that allows you to easily
access the G-560's management settings.
Logging and Tracing
Built-in message logging and packet tracing.
Wireless Association List
With the wireless association list, you can see the list of the wireless stations that are currently
using the G-560 to access your wired network.
Output Power Management
Output Power Management is the ability to set the level of output power.
There may be interference or difficulty with channel assignment when there is a high density
of APs within a coverage area. In this case you can lower the output power of each access
point, thus enabling you to place access points closer together.
Chapter 1 Getting to Know Your G-56025
ZyXEL G-560 User’s Guide
Limit the Number of Client Connections
You may set a maximum number of wireless stations that may connect to the G-560. This may
be necessary if for example, there is interference or difficulty with channel assignment due to
a high density of APs within a coverage area.
1.3 Applications for the G-560
Here are some application examples of what you can do with your G-560.
1.3.1 Access Point
1.3.1.1 Internet Access Application
The G-560 is an ideal access solution for wireless Internet connection. A typical Internet
access application for your G-560 is shown as follows.
Figure 2 Internet Access Application
1.3.1.2 Corporation Network Application
In situations where users need to access corporate network resources and the Internet, the G560 is an ideal solution for wireless stations to connect to the corporate network without
expensive network cabling. Stations A, B and C can access the wired network through the G560s.
The following figure depicts a typical application of the G-560 in an enterprise environment.
The three computers with wireless adapters are allowed to access the network resource
through the G-560 after account validation by the network authentication server.
26 Chapter 1 Getting to Know Your G-560
Figure 3 Corporation Network Application
1.3.2 Access Point + Bridge
ZyXEL G-560 User’s Guide
In Access Point + Bridge mode, the G-560 supports both AP (A and B can connect to the
wired network through X) and bridge (X can communicate with Y) connection at the same
time.
The G-560 can act as a wireless network bridge and establish wireless links with other APs. In
order to prevent bridge loops when the G-560 is in the bridge mode, you should ensure that
your G-560 is not connected to both wired and wireless segments of the same LAN. Also
make sure that you do not have three or more G-560s (in bridge mode and on different wired
LANs) wirelessly connect to each other.
When the G-560 is in Access Point + Bridge mode, the traffic between G-560s (the WDS) is
not encrypted. The security settings on the G-560 refer to the traffic between the wireless
station and the G-560.
