WIRELESS NETWORK OVERVIEW
A wireless local area network (LAN) is a flexible data communications system implemented as an
extension to, or as an alternative for, a wired LAN. Using radio frequency (RF) technology, wireless
LANs transmit and receive data over the air, minimizing the need for wired connections. Thus, wireless
LANs combine data connectivity with user mobility.
A local area network that transmit and receive over the air typically in an unlicensed frequency such as
the 2.4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like
IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a
radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other
nonmetal barriers. Roaming users can be handed off from one access point to another like a cellular
phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self
contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc.).
Wireless LANs offer the following productivity, convenience, and cost advantages over traditional wired
networks：
Mobility - WLAN provide LAN users to access data in any location within the operating range of the
WLAN. Ad-hoc management decisions based on real-time information can significantly improve worker
efficiency.
Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can
eliminate the need to pull cable through walls and ceilings.
Installation Flexibility - Wireless technology allows the network to go where wire cannot go.
Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware can
be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be
significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent
moves and changes.
Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs of
specific applications and installations. Configurations are easily changed and range from peer-to-peer
networks suitable for a small number of users to full infrastructure networks of thousands of users that
enable roaming over a broad area.
Installation Considerations
Designed to go up to 300 feet (100 meters) indoors and up to 900 feet (273 meters) outdoors, Laputa
PCI lets you access your network from virtually anywhere you want. Keep in mind, however, that the
number and thickness of walls, ceilings or other objects that the wireless signals must pass thru may
limit range. Typical ranges vary depending on the types of materials and background RF noise in your
home or business. The key to maximizing range is to follow these basic principles:
TwinMOS
Page 4
TwinMOS Laputa PCI
Keep the number of walls and ceilings between the access point and your receiving device to a minimum
- Each wall or ceiling can reduce your TwinMOS Laputa Wireless product’s range from 3-90 feet (1-30
meters.) For some businesses or for a large residential home deployment, it may be more beneficial to
have more than one access point with overlapping coverage.
1.
Be aware of the direct line between Access Points, Residential Gateways, and Computers - A wall
that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At
a 2-degree angle it looks over 42 feet (14 meters) thick! Try to make sure that the Access Points and
Adapters are positioned so that the signal will travel straight through a wall or ceiling for better
reception.
2.
Building Materials make a difference - A solid metal door or aluminum studs may have a negative
effect on range. Try to position Access Points, Residential Gateways, and Computers so that the
signal passes through drywall or open doorways and not other materials.
3.
Make sure that the antenna is positioned for best reception by using the software signal strength
tools included with your product.
4.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices that generate RF
noise, like microwaves, monitors, electric motors, etc.
For the average residence, range should not be a problem. If you experience low or no signal strength in
areas of your home that you wish to access, consider positioning the Access Point in a location directly
between the Residential Gateways and/or Computers that will be connected. Additional Access Points
can be connected to provide better coverage in rooms where the signal does not appear as strong as
desired.
Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the
need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through
simplified configuration, enable movable LANs.

Laputa PCI WIRELESS NETWORK SCENARIOS
The Laputa PCI enables you to:
Connect your computer to a Peer-to-Peer workgroup of wireless computing devices (see Figure 1-1 on
page 7).
Connect your computer to a Small Office/Home Office (SOHO) network that includes a Residential
Gateway (RG) access point (see Figure 1-2 on page 8).
Connect your computer to a Local Area Network (LAN) Infrastructure that includes Access Points, or
other IEEE 802.11 compliant LAN systems (see Figure 1-3 and Figure 1-4).
Expand the capabilities of your Access Points, to support wireless devices that have been equipped
with Laputa PCI.
Peer-to-Peer Workgroup
The Peer-to-Peer workgroup configuration enables you to quickly set up a small wireless workgroup,
where the workgroup participants can exchange files using features like “Files and Printer Sharing” as
supported by Microsoft Networking.
Figure 1-1 Peer-to-Peer Wireless Workgroup
You can use this option to setup a temporary or ad-hoc network in environments where no access points
are available (for example in Small Office/Home Office (SOHO) environments). 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.

It’s Easy
The Laputa PCI functions like any standard wired Ethernet card, but Laputa PCI does not need any
wires!
Where an Ethernet card requires a cable connection to a hub and/or patch panel, the cable physically ties
you down to the location of the wired connection.
Laputa PCI allows you to connect your computer to a Local Area Network (LAN) system from
anywhere within the wireless coverage area. Expanding or re-designing your network is easy: Add or
relocate access point, power-up your (new) wireless computers, and you’re done!
Unlike Ethernet, TwinMOS Laputa PCI will enable you to roam throughout the network while
remaining connected to the LAN.
Note：The Laputa PCI wireless adapter is a radio product. Refer to the flyer ”Information to the User”
for regulatory information that may apply in your country.

Profile
A profile is a named set of operating parameters for your Laputa PCI WLAN adapter. The Profile field
lets you set values for all parameters by selecting a previously defined profile. Click the down arrow at
the right of the Profile field to display the available profiles for your Laputa PCI WLAN adapter.
Mode
The Laputa PCI WLAN adapter can operate in one of two modes, which are specified in the Mode field
of the Configuration menu. Clicking the down arrow at the right of the Mode field displays the available
modes.
802.11b Ad Hoc - This is the 802.11b peer-to-peer mode of operation. In “Ad Hoc” mode, only
one wireless “cell” is supported for each different SSID. All communication is done from client
to client without the use of an Access Point. “802.11b Ad Hoc” networking uses the same SSID
for the wireless adapters in establishing the network connection. When “Ad Hoc” mode is
selected, the utility will provide a selection for setting the channel.
Infrastructure - This mode of operation requires the presence of an 802.11b Access Point. All
communication is done through the Access Point, which relays packets to other wireless clients
as well as to nodes on a wired Ethernet network.
TwinMOS
Page 21
TwinMOS Laputa PCI
SSID
The SSID is the Service Set IDentifier used by Access Points and stations to identify a wireless LAN.
The SSID is essentially a name that identifies your wireless network. All Access Points and all devices
attempting to connect to a specific Wireless network must use the same SSID.
Transmit Rate
The Transmit Rate field specifies the rate at which the radio in your Laputa PCI WLAN adapter
transmits and receives data. You can set this to the following fixed rates: 1 Mbps; 2Mbps; 5.5 Mbps or
11 Mbps.
Power Save Mode
Power Saving mode allows your computer to use reduced power during idle time by going into “sleep”
mode, saving energy costs.
Ad Hoc Channel
When communicating in AdHoc or Pseudo AdHoc mode, you must specify a channel on which
communications will take place. This field is grayed in infrastructure mode because the Access Point
automatically selects the channel.
Encryption Tab
The Encryption menu lets you enable encryption and set the encryption keys. To see the available
encryption methods, click the down arrow at the right of the Encryption (WEP) field.
There are two encryption methods available. The IEEE 802.11 specification defines Wired Equivalent
Privacy (WEP) using a 64-bit key. This capability was extended by the industry to allow a 128-bit key.
TwinMOS

Disabling Encryption
To disable encryption, click the down arrow at the right of the Encryption field, select Disabled, and
click the Apply button.
Disabling Encryption
To enable encryption, click the down arrow at the right of the Encryption field, select either 64 bit or 128
bit, and click the Apply button. After enabling an encryption method, you must then specify encryption
keys, as described in the following sections.
If you specify an encryption method, you will only be able to communicate with Access Points and
stations that use the same encryption method and keys.
Creating Encryption Keys Using a Passphrase
To create encryption keys using a passphrase, click the radio button next to Create Key with Passphrase
and type a character string in the Passphrase field. As you type, the Configuration Utility uses an
algorithm to generate four keys used for encryption.
When you finish typing your character string and click the Apply button, the Configuration Utility uses
asterisks to mask both your passphrase and the keys it generates.
Using a passphrase to generate the four keys makes it easy to set the same keys for all members of your
wireless LAN. Please make a record of your passphrase, so that you do not forget it. If you do forget
your passphrase, then disable encryption and create new passphrases.
Creating Encryption Keys Manually
If you wish, you can create encryption keys manually by selecting the Encryption tab.
button next to Manual Entry.
Click on the
When you click this button, the cursor appears in the field for Key 1. For 64-bit encryption, you must
type exactly 10 hexadecimal digits in each of the four key fields; for 128-bit encryption, you must type
exactly 26 hexadecimal digits. You then click the Apply button to create your encryption keys. After you
click the Apply button, the Configuration Utility uses asterisks to mask your keys. Remember to make a
note of your hexadecimal string for each key. If you do forget your digits for a key, disable encryption
and create a new key.
