This table describes the options available from the Configuration section:
CONFIGURATION
DESCRIPTION
Network Configurable between 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.
In infrastructure mode, the wireless node searches all available wireless
channels to associate with an access point.
Network Name Enter a 32-character (maximum) service set ID in this field; the characters are
(SSID) case sensitive.
When the wireless node is operating in ad-hoc mode, this field operates as the
basic service set ID (BSSID). All wireless nodes in the same network should use
the same BSSID.
When in infrastructure mode, this field defines the extended service set ID
(ESSID). The ESSID assigned to the wireless node is required to match the
access point ESSID in order for the wireless node to communicate with the
access point.
Turbo Mode Enabling turbo mode allows the wireless node to transmit or receive at a higher
rate, up to 72 Mbps.
Power Saving Supports optional power management to conserve battery life in Infrastructure
mode. The three possible settings are off, normal, and maximum. The HA311
“wakes up” every 10-beacon interval to listen to the normal mode, but “wakes
up” every 100-beacon interval in the maximum power saving mode.
Security: Sets the data encryption level for the wireless node. The data encryption level
Enable Security must be the same between all wireless nodes and access points within the same
network. The possible values for the data encryption level are Disable, 64 bits,
128 bits, and 152 bits. (The 64-bit data encryption is also called 40-bit data
encryption by some vendors.) For more Information on data encryption, please
refer to Chapter 4--Wireless Network Fundamentals.
Unchecking the Enable Security (WEP Key) box or 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. Use of 128-bit and 152-bit Shared Key data encryption methods are
also possible.
Shared Key The HA311 device with WEP enabled uses a WEP key to encrypt and decrypt
Entries information. An HA311 Wireless PCI Adapter can support up to four WEP keys.

CHAPTER 4—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 workgroup 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 expensive way to set up a
wireless network.
To set up an ad-hoc workgroup operating with standard protocols, do the
following:
♦
Set all stations to connect in Ad-hoc mode (or Peer-to-Peer workgroup
mode).
33
Download from Www.Somanuals.com. All Manuals Search And Download.
♦
♦
♦
Set all stations to use the same network name (or SSID).
Set all stations to use the same wireless channel for communication.
Set all stations to disable the WEP encryption key, or set all stations to use
an identical WEP encryption key as used by the Access Point.
INFRASTRUCTURE MODE
With a wireless access point, you can put the wireless LAN into Infrastructure
mode. It provides wireless connectivity to multiple wireless network devices
within a fixed range or area of coverage, interacting with a wireless node 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 HE102 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:
♦
♦
♦
♦
Set all wireless stations to connect in infrastructure mode
Set all stations to use the same network name (or SSID).
Set all wireless access points to use the same network name (or ESSID).
Set all stations to disable the WEP encryption key, or set all stations to use
an identical WEP encryption key as used by the Access Point.
34

♦
Set up wireless channels used by individual access points. (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 (SSID)
The Service Set Identification (SSID) 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 SSID.
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 (BSSID).
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 (ESSID).
Wireless clients configured with the same ESSID 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 a 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 three shared key methods implemented in Netgear’s 802.11a
solutions: the standard based forty-bit WEP data encryption and 128-bit WEP
data encryption plus the extended 152-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 and
the 152-bit WEP data encryption method consists of 128 configurable bits
Similar to the forty-bit WEP data encryption method, the remaining 24 bits are
factory set and not user configurable.

Wireless Channel Selection
IEEE 802.11a utilizes 300 MHz of bandwidth in the 5 GHz Unlicensed National
Information Infrastructure (U-NII) band. Though the lower 200 MHz is
physically contiguous, the FCC has divided the total 300 MHz into three distinct
domains, each with a different legal maximum power output.

IEEE 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM), a
new encoding scheme that offers certain benefits over a spread spectrum in
channel availability and data rate. The 802.11a uses OFDM to define a total of 8
non-overlapping 200 MHz channels across the 2 lower bands; each of these is
divided into 52 subcarriers and each carrier is approximately 300 KHz wide. By
comparison, 802.11b uses only 3 non-overlapping channels.
