CHAPTER 2: WIRELESS NETWORK FUNDAMENTALS
Wireless Network Configuration
Ad-hoc Mode (Peer-to-Peer Workgroup)
The Institute of Electrical and Electronics Engineers (IEEE) standard for wireless LANs (WLANs),
802.11, offers two methods for configuring a wireless network — ad hoc and infrastructure. In an ad hoc
network, computers are brought together as needed; thus, there is no structure or fixed points to the
network — each node can generally communicate with any other node. There is no access point involved
in this configuration. It enables you to quickly set up a small wireless workgroup and allows workgroup
members to exchange data or share printers as supported by Microsoft Networking in the various
Windows operating systems. Some vendors also refer to ad hoc networking as Peer-to-Peer group
networking.
In this configuration, network packets are directly sent and received by the intended transmitting and
receiving stations. As long as the stations are within range of one another, this is the easiest and least
expansive way to set up a wireless network.
To set up an ad hoc workgroup operating with standard protocols, do the following:
y Set all stations to connect in Ad-hoc mode (or Peer-to-Peer workgroup mode).
y Set all stations to use the same network name (or SS ID).
y Set all stations to use no WEP encryption key or an identical WEP encryption key.
y Set all stations to use the same wireless channel for communication.
Infrastructure Mode
With a wireless access point, you can put the wireless LAN into the infrastructure mode. It provides
wireless connectivity to multiple wireless network devices within a fixed range or area of coverage,
interacting with a wireless nodes via an antenna.
In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data,
acting as a bridge between the wired LAN and wireless clients. Connecting multiple access points via a
wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device
moves out of the range of one access point, it moves into the range of another. As a result, wireless clients
can freely roam from one Access Point domain to another and still maintain seamless network connection.
To set up an infrastructure network operating with standard protocols, do the following:
y Set all wireless stations to connect in infrastructure mode
y Set all stations to use the same network name (or SS ID).
y Set all wireless access point to use the same network name ( or ESS ID).
y Set all stations to use no WEP encryption key or an identical WEP encryption key.
y Set up wireless channels used by individual access point. (It is not necessary to set channels on the
stations as the stations will automatically scan through all channels for the nearest access point.)

Service Set Identification (SS ID)
The Service Set Identification (SS ID) is a thirty-two alphanumeric character (maximum) string
identifying the wireless local area network. Some vendors refer to the SS ID as network name. For
stations to communicate with each other, all stations must be configured with the same SS ID.
A wireless LAN consisting of nodes operating in ad hoc configuration without an access point is called a
Basic Service Set (BSS). All nodes in a BSS must use the same Basic Service Set ID (BSS ID).
In an infrastructure configuration with access points, multiple BSS can be configured to form an Extended
Service Set (ESS). In this configuration, the access points are configured with the same Extended Service
Set ID (ESS ID). Wireless clients configured with the same ESS ID can freely roam from one Access
Point domain to another and still maintain seamless connection to the network
Authentication and WEP Encryption
The absence of a physical connection between nodes makes the wireless links vulnerable to information
theft. To provide certain level of security, IEEE 802.11 standard has defined two types of authentication
methods, Open System and Shared Key. Open System authentication is a null algorithm. Shared Key
authentication is an algorithm where both the transmitting node and the receiving node share an
authentication key to perform a checksum on the original message. By default, IEEE 802.11 wireless
devices operate in an open system network.
Wired Equivalent Privacy (WEP) data encryption is utilized when the wireless nodes or access points are
configured to operate in Shared Key authentication mode. There are two shared key methods implemented
in most commercially available products, forty-bit WEP data encryption and 128-bit WEP data
encryption.
The forty-bit WEP data encryption method, allows for a five-character (forty-bit) input. Additionally, 24
factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 factory-set
bits are not user configurable.) This encryption key will be used to encrypt/decrypt all data transmitted via
the wireless interface. Some vendors may refer to the forty-bit WEP data encryption as 64-bit WEP data
encryption since the actual encryption key used in the encryption process is 64 bits wide.
The 128-bit WEP data encryption method consists of 104 configurable bits. Similar to the forty-bit WEP
data encryption method, the remaining 24 bits are factory set and not user configurable. Some vendors
allow passphrases to be entered instead of the cryptic hexadecimal characters to ease encryption key entry.

Wireless Channel Selection
IEEE 802.11 wireless nodes communicate with each other using radio frequency signals in the ISM
(Industrial, Scientific, and Medical) band between 2.4Ghz and 2.5Ghz. Neighboring channels are 5Mhz
apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular
channel will utilize frequency spectrum12.5Mhz above and below the center channel frequency. As a
result, two separate wireless networks using neighboring channels (for example, channel 1 and channel 2)
in the same general vicinity will interfere with each other. Applying two channels that allow the maximum
channel separation will decrease the amount of channel cross-talk, and provide a noticeable performance
increase over networks with minimal channel separation.
Channel Center Frequency Frequency Spread
1 2412Mhz 2399.5Mhz – 2424.5Mhz
2 2417Mhz 2404.5Mhz – 2429.5Mhz
3 2422Mhz 2409.5Mhz –2434.5Mhz
4 2427Mhz 2414.5Mhz –2439.5Mhz
5 2432Mhz 2419.5Mhz – 2444.5Mhz
6 2437Mhz 2424.5Mhz –2449.5Mhz
7 2442Mhz 2429.5Mhz –2454.5Mhz
8 2447Mhz 2434.5Mhz – 2459.5Mhz
9 2452Mhz 2439.5Mhz –2464.5Mhz
10 2457Mhz 2444.5Mhz –2469.5Mhz
11 2462Mhz 2449.5Mhz – 2474.5Mhz
12 2467Mhz 2454.5Mhz – 2479.5Mhz
13 2472Mhz 2459.5Mhz – 2484.5Mhz
Note: The available channels supported by the wireless products in various countries are
different.
The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5
channels). This means that you can apply up to three different channels within your wireless network.
There are only 11 usable wireless channels in the United States. It is recommended that you start using
channel 1 and grow to use channel 6, and 11 when necessary.

communication with an access point and the signal
quality is strong.
MA401 Parameter Modification
Double-clicking on the wireless SysTray icon activates the wireless LAN configuration utility for the
MA401 Wireless PC Card. You can click on any of the folder tab in the Wireless LAN configuration
utility window to modify the operational parameters.
.
Status
Status This field show the MAC address of the associated access point when the
MA401 Wireless PC Card is configured in infrastructure mode,
Current Channel The wireless channel in use, between 1 and 13. The number of wireless
channels supported by the different countries may vary. Click on the
Configuration folder tab if you want to fix the wireless node to use a
particular wireless channel.
Current Tx Rate The current transmit data rate of the wireless node. The possible
configurations are 1Mbps, 2Mbps, 5.5Mbps and 11Mbps. In ad hoc mode,
this field shows what the wireless node is configured to use. When in
infrastructure mode, it shows the result of the transfer rate negotiated
between the access point and the wireless node.

16
Rescan Only used in infrastructure mode, click on this button to allow the wireless
node to start scanning the wireless channels for an access point again.
Throughput (Bytes/sec) Tx The current transmit data transfer rate of the wireless node.
Throughput (Bytes/sec) Rx The current receive data transfer rate of the wireless node.
Signal Strength Signal Strength indicates the signal strength of the radio frequency signal
received by the wireless node.
Link Quality Link Quality indicates how well that the wireless node is communicating
with the associated access point or another wireless node.
Configuration
Network Mode Configurable between 802.11 ad-hoc, ad-hoc, and infrastructure modes. In
802.11 ad hoc mode, the wireless nodes form their own local network where the
end nodes communicate peer-to-peer without an access point. Ad-hoc mode offers
higher data throughput than 802.11 ad hoc mode; but it does not use beacon or
authentication.
Note: When in 802.11 Ad-hoc mode, Link Quality and Signal Strength indicators
will not be available.
In infrastructure mode, the wireless searches all available wireless channels to
associate with an access point.
SSID Enter a 32-character (maximum) service set ID in this field. The characters are
case sensitive. When the wireless node is operating in ad hoc mode, this field
operates as the basic service set ID (BSS ID). All wireless nodes in the same
network should use the same BSS ID.
When in infrastructure mode, this field defines the extended service set ID (ESS
ID). The ESS ID assigned to the wireless node is required to match the access
point ESS ID for the wireless node to communicate with the access point.
Tx Rate The Tx Rate field allows you to define the data transfer rate. The default value is
Fully Automatic. In this case, the best transfer rate is negotiated between the
wireless node and the device it is communicating with. This could be another
wireless node or an access point. Other possible values for this field are 1Mbps,
2Mbps, 5.5Mbps, and 11Mbps.
PS Mode Power saving mode. This enables the wireless node to control its wireless power
consumption. The two possible settings are Enable and Disable.
Channel Only valid in ad-hoc mode, this field defines the wireless channel to use. In
infrastructure mode, the wireless node automatically searches through all
available wireless channels for an access point to be associated with. It is not
necessary to select the wireless channel when operating in infrastructure mode.

Encryption
Encryption Set the data encryption level for the wireless node. The data encryption level
must be the same between all wireless nodes and access points in the same
network. The possible values for the data encryption level are Disable, 64 bits
and 128 bits. 64-bit data encryption is also called 40-bit data encryption by
some vendors. For more explanation on data encryption, please refer to the
wireless network fundamental chapter at the beginning of this reference guide.
Setting the data encryption level to Disable is to not use any encryption; this is
also called Open System data encryption. Setting the data encryption level to
64-bit configures the wireless node to use the 40-bit (also called 64-bit) Shared
Key data encryption method. 128-bit encryption is another possible Shared Key
data encryption method.
WEP Key
Entry/Passphrase A 32-character (maximum) passphrase can be used to generate the encryption key when using the Shared Key (64-bit or 128-bit) data encryption method.
However, this field is only visible when entering the passphrase for the first
time. When the encryption folder tab is open for the second time, the
passphrase will not be visible. Make a note of the passphrase when providing it
to the wireless node, as this information is needed for all other wireless nodes
on the same network.
WEP Key
Entry/Manual
Entry
The encryption key used to encrypt/decrypt wireless data. When set to 64-bit
(also called 40-bit) data encryption mode, you may specify up to four different
keys to encrypt wireless data. However, only one key is allowed in the 128-bit
data encryption mode.
Default Tx Key When the encryption level is set to 64-bit (also called 40-bit by some other
vendors), the wireless LAN configuration utility allows you to specify up to four
different keys to encrypt wireless data. The Default Tx field allows you to
specify which one of the four keys to activate.
