Introduction
At up to fifteen times the maximum wireless signal rate of previous wireless devices (up
to 108Mbps* in Super G mode), you can work faster and more efficiently, increasing
productivity . With the DWL-G800AP, bandwidth-intensive applications like graphics or
multimedia will benefit significantly because large files are able to move across the
network quickly .
The D-Link AirPlus XtremeTM G DWL-G800AP Wireless Range Extender is an enhanced
802.11g high-performance, wireless device. It is an ideal way to extend the reach and
number of computers connected to your wireless network.
The DWL-G800AP can act as an access point or a wireless repeater . In repeating mode,
the DWL-G800AP repeats the wireless signal of D-Link AirPlus Xtreme
points and wireless routers to extend the range of your wireless network.
Unlike most 802.11g devices, the DWL-G800AP is capable of data transfer rates up to
108Mbps* when used with other D-Link AirPlus XtremeTM G products such as the
DWL-G520 Wireless PCI Adapter, DWL-G650 Wireless Cardbus Adapter, and the DI624 Wireless Router.
The DWL-G800AP is compatible with most popular operating systems, including
Macintosh, Linux and Windows, and can be integrated into a large network.
The DWL-G800AP has the newest, strongest and most advanced security features
available today . When used with other 802.1 1 WP A (Wi-Fi Protected Access) and 802.1x
compatible products in a network with a RADIUS server , the security features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based on a
secret key that changes automatically at regular intervals. WPA uses TKIP
(T emporal Key Integrity Protocol) to change the temporal key every 10,000
packets (a packet is a kind of message transmitted over a network.) This ensures
much greater security than the standard WEP security . (By contrast, the previous
WEP encryption implementations required the keys to be changed manually .)
802.1x: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server verifies the identity of the
client attempting to connect to the network. Unfamiliar clients would be denied
access.
TM
G access
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-G800AP , used in conjunction with other WP A-comp atible 802.1 1 products,
will still be much stronger than ever before. Utilizing the Pre-Shared Key mode of
WPA, the DWL-G800AP will obtain a new security key every time it connects to the
802.11 network. You only need to input your encryption information once in the
configuration menu. No longer will you have to manually input a new WEP key frequently
to ensure security. With the DWL-G800AP, you will automatically receive a new key
every time you connect, vastly increasing the safety of your communication.
*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput
will vary. Network conditions and environmental factors lower actual data throughput rate.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and
compatible high-speed wireless connectivity within your home, business or public access
wireless networks. D-Link wireless products will allow you access to the data you want,
when and where you want it. Y ou will be able to enjoy the freedom that wireless networking
brings.
A wireless local area network (WLAN) is a computer network that transmits and receives
data with radio signals instead of wires. WLANs 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.
People use WLAN technology for many different purposes:
Mobility
within the operating range of the WLAN. Management decisions based on real-time
information can significantly improve worker efficiency .
- Productivity increases when people have access to data in any location
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.

Wireless Basics (continued)
The DWL-G800AP is compatible, in default mode, with the following wireless products:
D-Link AirPlus Xtreme G DWL-G650
Wireless Cardbus Adapters used with laptop computers
D-Link AirPlus Xtreme G DI-624-Firmware 2.37 or newer (Rev.C)
Wireless Router
The DWL-G800AP is also interoperable with other 802.11g and 802.11b
standards-compliant devices.
Standards-Based Technology
The DWL-G800AP Wireless Range Extendert utilizes the 802.11b and the 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, utilizing 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 D-Link DWLG800AP will automatically sense the best possible connection speed to ensure the
greatest speed and range possible.

Installation Considerations
The D-Link AirPlus Xtreme G DWL-G800AP lets you access your network, using a
wireless connection, 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. T ypical 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:
Keep the number of walls and ceilings between the DWL-G800AP and other
1
network devices to a minimum - each wall or ceiling can reduce your DWLG800AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the
number of walls or ceilings is minimized.
Be aware of the direct line between network devices. A wall that is 1.5 feet thick
2
(.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.
Building materials can impede the wireless signal - a solid metal door or aluminum
3
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.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices
4
or appliances that generate RF noise.
