Introduction
The 54Mbps Access Point provides the most expanded user bandwidth available in an
AP. Network members can connect to this AP using any of its channels to transfer data
at speeds never achievable before in a wireless device. The 54Mbps Access Point
operates seamlessly and simultaneously in the 2.4GHz frequency spectrums supporting
the 802.11b and the newer, faster 802.11g wireless standards. For offices, schools or
public hotspots that already use 802.11b devices, the 54Mbps Access Point is a great
way to expand an existing network and enable even more users to communicate with
one another, access data and the Internet. Now, you can have an AP that will
compliment your existing network and protect the investment you made when you
provided the convenience of wireless networking.
The 54Mbps Access Point offers transfer rates up to 54Mbps in the 2.4GHz band, large
data packets travel from the router to a remote desktop or roaming laptop PC at up to
five times the speed of previous wireless devices. Everyone can work faster and more
efficiently or watch a streaming video smoothly. Network administrators can partition the
usage of the 54Mbps Access Point by segmenting the users on the wireless network by
frequency band. Users who require special networking privileges — access to sensitive
information, specific departments or videoconferencing — may use just the 802.11b and
802.11g channels. This type of user segmentation optimizes the AP’s performance and
delivers the best network experience to each set of users.
The 54Mbps Access Point is ideal for network administrators who require additional
management, firewall, and other network security features. All of the AP’s settings are
easily accessible in the operating system independent, Web-based software user
interface that also features a step-by-step Setup Wizard to get your router up and
running in just a matter of minutes. The 54Mbps Access Point incorporates the WPA*
(Wi-Fi Protected Access) which dynamically encrypts data as it’s being sent.

Wireless Basics
The 54Mbps Access Point is based on industry standards to provide easy-to use and
compatible high-speed wireless connectivity within your home, business or public access
wireless networks. Strictly adhering to the IEEE standard, the 54Mbps Access Point will
allow you to securely access the data you want, when and where you want it. You will be
able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and
receives data with radio signals instead of wires. Wireless LANs are used increasingly in
both home and office environments, and public areas such as airports, coffee shops and
universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently. Increased mobility and the absence of cabling and other
fixed infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network. Wireless
adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a
conventional Ethernet LAN in order to use servers, printers or an Internet connection
supplied through the wired LAN. A Wireless Access Point (AP) is a device used to
provide this link.
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any location within
the operating range of the WLAN. Management decisions based on real-time information
can significantly improve worker efficiency.
Low Implementation Costs – WLANs are easy to set up, manage, change and relocate.
Networks that frequently change can benefit from WLANs ease of implementation.
WLANs can operate in locations where installation of wiring may be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and easy
and can eliminate the need to pull cable through walls and ceilings. Wireless technology
allows the network to go where wires cannot go - even outside the home or office.
Inexpensive Solution – Wireless network devices are as competitively priced as
conventional Ethernet network devices.
Scalability – WLANs can be configured in a variety of ways 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 larger infrastructure
networks to accommodate hundreds or thousands of users, depending on the number of
wireless devices deployed.

The 54Mbps Access Point is compatible with the IEEE802.11g wireless products:
802.11g Wireless Cardbus Adapters used with laptop computers and 802.11g
Wireless PCI cards used with desktop computers
Standards-Based Technology
The 54Mbps Access Point utilizes the 802.11b and 802.11g standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band. 802.11g utilize OFDM technology.
This means that in most environments, within the specified range of this device, you will
be able to transfer large files quickly or even watch a movie in MPEG format over your
network without noticeable delays. This technology works by transmitting high-speed
digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division
Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller
sub-signals that are then transmitted simultaneously at different frequencies to the
receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions.
The 54Mbps Access Point offers the most advanced network security features available
today, including: WPA.
In addition to its compatibility with 802.11g devices, the 54Mbps Access Point is
compatible with 802.11b devices. This means that if you have an existing 802.11b
network, or a network with a mixture of 802.11g and 802.11b, the devices in that network
will be compatible with the 54Mbps Access Point.

Installation Considerations
Desktop and laptop computers with wireless network adapters installed can access the
54Mbps Access Point from virtually anywhere within its operating range. Keep in mind,
however, that the number, thickness and location of walls, ceilings, or other objects that
the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your
home or business. The key to maximizing wireless range is to follow these basic
guidelines:
1
Keep the number of walls and ceilings between the 54Mbps Access Point and other
network devices to a minimum - each wall or ceiling can reduce your wireless product’s
range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.
2
Be aware of the direct line between network devices. 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! Position devices so that the signal will travel
straight through a wall or ceiling (instead of at an angle) for better reception.
3
Building materials can impede the wireless signal - a solid metal door or aluminum studs
may have a negative effect on range. Try to position wireless devices and computers
with wireless adapters so that the signal passes through drywall or open doorways and
not other materials.
4
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that may generate extreme RF noise.

IP ADDRESS
Note: If you are using a DHCP-capable router in your network setup you will
not need to assign a static IP Address.
If you need to assign IP Addresses to the computers on the network, please
remember that the IP Address for each computer must be in the same IP
Address range as all the computers in the network, and the Subnet mask
must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IP Address of 10.0.0.2 with
a Subnet Mask of 255.0.0.0, then the second computer can be assigned an
IP Address of 10.0.0.3 with a Subnet Mask of 255.0.0.0, etc.
IMPORTANT: If computers or other devices are assigned the same IP
Address, one or more of the devices may not be visible on the network.

11
An Infrastructure wireless network contains an Access Point or Router. The
Infrastructure Network example, shown here, contains the following network devices:
For a typical wireless setup (as shown above), please do the following:
