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, Netkey
WLAN adapter lets you access your network fromvirtually 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:

Netkey Series WLAN Card
WWW.TwinMOS.COM Page 5
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 Netkey 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.

Netkey WIRELESS NETWORK SCENARIOS
The Netkey WLAN adapter enables you to:
lConnect your computer to an Ad-Hoc workgroup of wireless computing devices (see Figure 1-1 on
page 7).
lConnect your computer to a Small Office/Home Office (SOHO) network that includes a Residential
Gateway (RG) access point (see Figure 1-2on page 8).
lConnect your computer to a Local Area Network (LAN) Infrastructure that includes Access Points, or
other IEEE 802.11 compliant LAN systems (see Figure 1-3and Figure 1-4).
lExpand the capabilities of your Access Points, to support wireless devices that have been equipped
with Netkey.
Ad-Hoc Workgroup
The Ad-Hoc 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 1-1Ad-Hoc 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 Netkey functions like any standard wired Ethernet card, but Netkey 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.
Netkey 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 Netkey will enable you to roam throughout the network while remaining
connected to the LAN.
Note：The Netkey wireless adapter is a radio product. Refer to the flyer ”Information to the User” for
regulatory information that may apply in your country.
