1.8 Network Configuration
To better understand how the wireless LAN products work together to create a
wireless network, it might be helpful to depict a few of the possible wireless LAN PC
card network configurations. The wireless LAN products can be configured as:
a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
b) Infrastructure for enterprise LANs.
c) Wi-Fi Mesh Networks
a) Ad-hoc (peer-to-peer) Mode
This is the simplest network configuration with several computers equipped with the
PC Cards that form a wireless network whenever they are within range of one another.
In ad-hoc mode, each client is peer-to-peer, would only have access to the resources
of the other client and does not require an access point. This is the easiest and least
expensive way for the SOHO to set up a wireless network. The image below depicts a
network in ad-hoc mode.
b) Infrastructure Mode
The infrastructure mode requires the use of an access point (AP). In this mode, all
wireless communication between two computers has to be via the AP. It doesn’t
matter if the AP is stand-alone or wired to an Ethernet network. If used in stand-alone,
the AP can extend the range of independent wireless LANs by acting as a repeater,
which effectively doubles the distance between wireless stations. The image below
depicts a network in infrastructure mode.
Page 14

c) Wi-Fi Mesh Networks
A Wireless Mesh Network constructed from WiFi Technology alleviates a number of
roaming challenges from laptops, IP phones, PDAs, and IP base devices:
No geographical limitations – User can take a handheld or laptop computer anywhere
without losing the connection in their home
No physical connection required – Mobile IP connects automatically and obtains local
IP router information
Supports security – Authentication is performed to ensure that rights are being
protected
Access Anytime, Anywhere – Network access is assured at all times and from all
locations. No missed E-mails and increase productivity due to constant connectivity.
Emergencies – Rapidly deployable and robust communications between each member
when emergencies are involved in difficult operations inside buildings, towers, or
surrounded in forest fires
Military Usage – Soldiers in a battlefield are exchanging information about their
position and giving and receiving orders, or the instructions

between wireless and wired devices.
Page 28
27
Band: Select a wireless band from the drop-down list: 802.11a, 802.11b, or
802.11g.
ESSID: The SSID is a unique named shared amongst all the points of the
wireless network. The SSID must be identical on all points of the wireless
network and cannot exceed 32 characters
Frequency: Select a frequency/channel from the drop-down list. The channels
available are based on the country’s regulation. A wireless network uses
specific channels in the wireless spectrum to handle communication between
clients. Some channels in your area may have interference from other
electronic devices. Choose the clearest channel to help optimize the
performance and coverage of your wireless network.
Beacon Period: Beacons are packets sent by a wireless Access Point to
synchronize wireless devices. Specify a Beacon Period value between 20 and
1000. The default value is set to 100 milliseconds.
RTS Threshold: Packets over the specified size will use the RTS/CTS
mechanism to maintain performance in noisy networks and preventing hidden
nodes from degrading the performance. Specify a value between 1 and 65535.
The default value is 2346.
Fragment Threshold: Packets over the specified size will be fragmented in
order to improve performance on noisy networks. Specify a value between 256
and 65535. The default value is 2346.
DTIM Interval: A DTIM is a countdown informing clients of the next
window for listening to broadcast and multicast messages. When the wireless
Access Point has buffered broadcast or multicast messages for associated
clients, it sends the next DTIM with a DTIM Interval value. Wireless clients
detect the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1.
Data rate: Select a data rate from the drop-down list or select auto.
Diversity: A method for improving the reliability of a message signal by
utilizing two or more communication channels with different characteristics,

Base Datarate max Tx power: Default output power of the device.
Current Datarate max Tx power: You may control the output power of the
device by selecting a value from the drop-down list.
Security: You may select WEP or WPA security. WEP is an acronym for
Wired Equivalent Privacy, and is a security protocol that provides the same
level of security for wireless networks as for a wired network. WEP is not as
secure as WPA encryption. To gain access to a WEP network, you must know
the key. The key is a string of characters that you create. When using WEP,
you must determine the level of encryption. The type of encryption determines
the key length. 128-bit encryption requires a longer key than 64-bit encryption.
Keys are defined by entering in a string in HEX (hexadecimal - using
characters 0-9, A-F) or ASCII (American Standard Code for Information
Interchange - alphanumeric characters) format. ASCII format is provided so
you can enter a string that is easier to remember. The ASCII string is
converted to HEX for use over the network.
Encryption Key: Specify the WEP encryption key.
WPA Security: You may select WEP or WPA security. WPA (Wi-Fi Protected
Access) was designed to improve upon the security features of WEP (Wired
Equivalent Privacy). The technology is designed to work with existing Wi-Fi
products that have been enabled with WEP. WPA provides improved data
encryption through the Temporal Integrity Protocol (TKIP), which scrambles
the keys using a hashing algorithm and by adding an integrity checking feature
which makes sure that keys haven’t been tampered with.
WPA Type: The encryption algorithm used to secure the data communication.
Page 30
29
TKIP (Temporal Key Integrity Protocol) provides per-packet key generation
and is based on WEP. AES (Advanced Encryption Standard) is a very secure
block based encryption. Note that, if the bridge uses the AES option, the
bridge can associate with the access point only if the access point is also set to
use only AES. The device negotiates the cipher type with the access point, and
uses AES when available.
802.1x: This option works with a RADIUS Server to authenticate wireless
clients. Wireless clients should have established the necessary credentials
before attempting to authenticate to the Server through this Gateway.
Furthermore, it may be necessary to configure the RADIUS Server to allow
this Gateway to authenticate users.
Encryption Key: Specify the WPA encryption key.
Click on the Save Changes button to store and changes and then reboot the
device in order for the changes to take effect.

WPA (Wi-Fi Protected Access) was designed to improve upon the security
features of WEP (Wired Equivalent Privacy). The technology is designed to
work with existing Wi-Fi products that have been enabled with WEP. WPA
provides improved data encryption through the Temporal Integrity Protocol
(TKIP), which scrambles the keys using a hashing algorithm and by adding an
integrity checking feature which makes sure that keys haven’t been tampered
with.
WPA Type: The encryption algorithm used to secure the data communication.
TKIP (Temporal Key Integrity Protocol) provides per-packet key generation
and is based on WEP. AES. Use AES only. AES (Advanced Encryption
Standard) is a very secure block based encryption. Note that, if the bridge uses
the AES option, the bridge can associate with the access point only if the
access point is also set to use only AES. TKIP and AES. The bridge negotiates
the cipher type with the access point, and uses AES when available.
