Chapter 2 Wireless LAN Network
This chapter provides background information on wireless LAN network.
2.1 Overview
This section describes the wireless LAN network terms and applications.
2.1.1 SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network. Wireless devices must have the same SSID to communicate with each other.
2.1.2 Channel
A radio frequency used by a wireless device is called a channel.
2.1.3 Transmission Rate (Tx Rate)
The ZyAIR provides various transmission (data) rate options for you to select. Options include
Fully Auto
,
1 M bit/sec
,
2 M bit/sec
,
5.5M bit/sec
,
11M bit/sec
,
16.5M bit/sec
and
networking scenarios, the factory default transmission rate.
Fully Auto
setting proves the most efficient. This setting allows your ZyAIR to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the ZyAIR automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the ZyAIR gradually increases the transmission (data) rate again until it reaches the highest available You can select any of the above options.
If you wish to balance speed versus reliability, select
11M bit/sec
or
5.5M bit/sec
in a networking environment where you are certain that all wireless devices can communicate at the highest transmission (data) rate.
1M bit/sec
or
2M bit/sec
are used often in networking environments where the range of the wireless connection is more important than speed. 3 The transmission rate of 27.5M bit/sec is not available at the time of writing. Wireless LAN 2-1
ZyAIR Wireless LAN Utility
For ZyAIR B122 and ZyAIR B-320, you may select the proprietary transmission rates of
16.5M bit/sec
or
27.5M bit/sec
if you are connecting to another ZyAIR B 320, ZyAIR B-122 client or ZyAIR B-500 AP and vice versa.
2.1.4 Wireless Network Application
Wireless LAN works in either of the two modes: ad-hoc and infrastructure. To connect to a wired network within a coverage area using Access Points (APs), set the ZyAIR operation mode to
Infrastructure(BSS)
. An AP acts as a bridge between the wireless stations and the wired network. In case you do not wish to connect to a wired network, but prefer to set up a small independent wireless workgroup without an AP, use the
Ad-hoc (IBSS)
(Independent Basic Service Set) mode.
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless clients communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS).
Figure 2-1 IBSS Example
4 At the time of writing, the proprietary transmission rates are only available for ZyAIR B-122, ZyAIR B 320 and ZyAIR B-500. 2-2 Wireless LAN
ZyAIR Wireless LAN Utility
Figure 2-2 BSS Example
A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set (ESS) or infrastructure network. All communication is done through the AP, which relays data packets to other wireless clients or devices connected to the wired network. Wireless clients can then access resource, such as the printer, on the wired network.
Figure 2-3 Infrastructure Network Example Access Point Mode
The following figure depicts a network example in which you set the ZyAIR in access point mode. Wireless LAN 2-3
ZyAIR Wireless LAN Utility
Figure 2-4 ZyAIR as an Access Point Example
In the example, the ZyAIR is installed on computer A and set to operate in access point mode. Computer A shares Internet connection to the wireless LAN, so wireless stations B and C can access the Internet.
2.1.5 Roaming
In an infrastructure network, wireless stations are able to switch from one BSS to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization or other factors. The following figure depicts a roaming example. When wireless client B moves to position X, the ZyAIR in wireless client B automatically switches the channel to the one used by access point 2 in order to stay connected to the network.
Figure 2-5 Roaming Example

Security
screen. If you do not enable any wireless security on your ZyAIR, the ZyAIR’s wireless communications are accessible to any wireless networking device
2.2.1 Data Encryption with WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the ZyAIR and the AP or other wireless stations to keep network communications private. Both the wireless clients and the access points must use the same WEP key for data encryption and decryption. There are two ways to create WEP keys in your ZyAIR. • Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the
Security
screen of the ZyAIR Utility and entering them manually as the WEP keys in the other WLAN adapter(s). • Enter the WEP keys manually. Your ZyAIR allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can be enabled at any one time. A
Fragmentation Threshold
is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the ZyAIR will fragment the packet into smaller data frames. A large
Fragmentation Threshold
is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference. If the
Fragmentation Threshold
value is smaller than the will be fragmented before they reach
RTS/CTS Threshold RTS/CTS Threshold
size. value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames A hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot “hear” each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Wireless LAN 2-5
ZyAIR Wireless LAN Utility
Figure 2-6 RTS Threshold
When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
RTS/CTS Threshold
handshake is invoked. is designed to prevent collisions due to hidden nodes. An
RTS/CTS Threshold
defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) When a data frame exceeds the
RTS/CTS Threshold
value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission. Stations can send frames smaller than the specified
RTS/CTS Threshold
directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure
RTS/CTS Threshold
if the possibility of hidden nodes exists on your network and the “cost” of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the
RTS/CTS Threshold
before they reach value is greater than the
RTS/CTS Threshold
size.
Fragmentation Threshold
value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented
Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance.
The IEEE 802.11b standard describes a simple authentication method between the wireless clients and AP. Three authentication modes are defined: Auto, Open and Shared. 2-6 Wireless LAN
ZyAIR Wireless LAN Utility Open authentication mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP do
not
share a secret key. Thus the wireless stations can associate with any AP and listen to any data transmitted plaintext. Shared authentication mode involves a shared secret key to authenticate the wireless station to the AP. This requires you to enable a security feature and specify a shared secret key (usually the WEP encryption and WEP key) on both the wireless station and the AP. Auto authentication mode allows the ZyAIR to switch between the open and shared key authentication modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless clients. A preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes:
Long Preamble
and
Short Preamble
. Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless clients support it. Select
Long Preamble
if you have a ‘noisy’ network or are unsure of what preamble mode the access point or the other wireless clients support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the ZyAIR and the access point/wireless stations and to provide more reliable communication in ‘noisy’ networks. Select
Auto
to have the ZyAIR automatically use short preamble when all access point/wireless stations support it, otherwise the ZyAIR uses long preamble. The ZyAIR and the access point/wireless stations MUST use the same preamble mode in order to communicate.

Appendix A Setting up Your Computer’s IP Address
All computers must have a 10M or 100M Ethernet adapter card and TCP/IP installed. Windows 95/98/Me/NT/2000/XP, Macintosh OS 7 and later operating systems and all versions of UNIX/LINUX include the software components you need to install and use TCP/IP on your computer. Windows 3.1 requires the purchase of a third-party TCP/IP application package. TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems. After the appropriate TCP/IP components are installed, configure the TCP/IP settings in order to "communicate" with your network. If you manually assign IP information instead of using dynamic assignment, make sure that your computers have IP addresses that place them in the same subnet as the ZyAIR.
