Introduction
The D-Link AirPlus Xtreme G DI-624 High-Speed Wireless Router is an 802.11g high-
performance, wireless router that supports high-speed wireless networking at home, at
work or in public places.
Unlike most routers, the DI-624 provides data transfers at up to 54 Mbps (compared to
the standard 11 Mbps) when used with other D-Link AirPlus Xtreme G products. The
802.11g standard is backwards compatible with 802.11b products. This means that you
do not need to change your entire network to maintain connectivity. You may sacrifice
some of 802.11g’s speed when you mix 802.11b and 802.11g devices, but you will not
lose the ability to communicate when you incorporate the 802.11g standard into your
802.11b network. You may choose to slowly change your network by gradually replacing
the 802.11b devices with 802.11g devices .
In addition to offering faster data transfer speeds when used with other 802.11g products,
the DI-624 has the newest, strongest, most advanced security features available today.
When used with other 802.11g WPA  (WiFi Protected Access) and 802.1x compatible
products in a network with a RADIUS server, the security features include:
WPA: Wi-Fi Protected Access authorizes and identifies users based on a secret key
that changes automatically at a regular interval. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a
packet is a kind of message transmitted over a network.) This insures much
greater security than the standard WEP security. (By contrast, the older WEP
encryption required the keys to be changed manually.)
802.1x:Authentication is a first line of defense against intrusion. In the Authentication
process the server verifies the identity of the client attempting to connect to the
network. Unfamiliar clients would be denied access.
For  home users that will not incorporate a RADIUS server in their network, the security
for the DI-624, used in conjunction with other 802.11g products, will still be much stronger
than ever before. Utilizing the Pre Shared Key mode of WPA, the DI-624 will obtain a
new security key every time it connects to the 802.11g 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 DI-624, you will
automatically receive a new key every time you connect, vastly increasing the safety of
your communications.

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. You will be able to enjoy the freedom that wireless networking
brings.
A WLAN is a cellular 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 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.
Scalability – WLANs 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 larger infrastructure
networks to accommodate hundreds or thousands of users, depending on the number
of wireless devices deployed.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices. 
						

							9 Standards-Based Technology
The  DI-624 Wireless Broadband Router utilizes the new 802.11g standard.
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 DI-624 is backwards compatible with 802.11b devices. This means that if you have
an existing 802.11b network, the devices in that network will be compatible with 802.11g
devices at speeds of up to 11Mbps in the 2.4GHz range.

Installation Considerations
The D-Link AirPlus Xtreme G DI-624 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. 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:
Keep the number of walls and ceilings between the DI-624 and other network
devices  to a minimum - each wall or ceiling can reduce your D-Link wireless
product’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 (.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.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise. 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.
