to provide a wireless data rate of up
to 11Mbps - that means you can migrate your system to the 802.11g standard
on your own schedule without sacrificing connectivity.
±
Better security with WPA -
The DWL-2200AP can securely connect to
wireless clients on the network using WPA (Wi-Fi Protected Access) providing a
much higher level of security for your data and communications than has
previously been available.
±
AP Manager Setup Wizard -
The new Setup Wizard makes network
configuration quick and simple.
±
SNMP for Management -
The DWL-2200AP is not just fast but it also
supports SNMP v.3 for a better network management. Superior wireless AP
manager software is bundled with the DWL-2200AP for network configuration
and firmware upgrade. Systems administrators can also setup the DWL-2200AP
easily with the Web-based configuration. A D-Link D-View module will be
downloadable for network administration and real-time network traffic
monitoring with D-Link D-View software.

Wireless Basics
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.
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 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.
People use WLAN 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. The DWL-2200AP saves money by providing
multi-functionality, configurable in one of four different modes.
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.

Standards-Based Technology
The DWL-2200AP Wireless Access Point 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
maximum wireless signal rate of up to 54Mbps* (maximum wireless signal rate of up to
108Mbps* in Super G mode)
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
(
O
rthogonal
F
requency
D
ivision
M
ultiplexing)
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
DWL-2200AP will automatically sense the best possible connection speed to ensure
the greatest speed and range possible.
802.11g offers WPA,
the most advanced network security features available today.
*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.

Installation Considerations
The D-Link
Air
Premier DWL-2200AP 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 your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that generate RF noise.
4
Keep the number of walls and ceilings between the DWL-2200AP and other
network devices
to a minimum - each wall or ceiling can reduce your DWL-2200AP’s
range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.
1
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.
2
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.
