UThe Wireless Technology
Standard
The 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 data rate up to 54 Mbps (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 you’re 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 cross talk (interference) in signal
transmissions. The AP will automatically sense the best possible connection
speed to ensure the greatest speed and range possible. 802.11g offers the
most advanced network security features available today, including: WPA, TKIP,
AES and Pre-Shared Key mode.
UPlanning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one wireless
adapter. Computers in a wireless network must be configured to share the
same radio channel. Several PCs equipped with wireless cards or adapters can
communicate with one another to form an ad-hoc network. The wireless
adapters also provide users access to a wired network when using an access
point or wireless router. An integrated wireless and wired network is called an
infrastructure network. Each wireless PC in an infrastructure network can talk
to any computer in a wired network infrastructure via the access point or
wireless router. An infrastructure configuration extends the accessibility of a
wireless PC to a wired network, and may double the effective wireless
transmission range for two wireless adapter PCs. Since an access point is able
to forward data within a network, the effective transmission range in an
infrastructure network may be doubled.

Roaming
Infrastructure mode also supports roaming capabilities for mobile users.
Roaming means that you can move your wireless PC within your network and
the access points will pick up the wireless PC's signal, providing that they both
share the same channel and SSID. Before enabling you consider roaming,
choose a feasible radio channel and optimum access point position. Proper
access point positioning combined with a clear radio signal will greatly enhance
performance.
Network Layout
The AP Access Point has been designed for use with 802.11g and 802.11b
products. With 802.11g products communicating with the 802.11b standard,
products using these standards can communicate with each other. The Access
point is compatible with 802.11g and 802.11b adapters, such at the PC Cards
for your laptop computers, PCI Card for your desktop PC, and USB Adapters for
when you want to enjoy USB connectivity. These wireless products can also
communicate with a 802.11g or 802.11b wireless Print Server. When you wish
to connect your wired network with your wireless network, the Access Point’s
network port can be used to connect to any of switches or routers.
Installation Considerations
The AP 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:
zKeep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
zKeep the number of walls and ceilings between the AP and other network
devices to a minimum - each wall or ceiling can reduce your AP’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of
walls or ceilings is minimized.
zBe 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

4
ceiling (instead of at an angle) for better reception.
zBuilding 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.

Making a Connection
Attention:
z
T
he cable distance between the Router and PC/hub/Switch should
not exceed 100 meters.
zMake sure the wiring is correct. In 10Mbps operation, Category
3/4/5 cable can be used for connection. To reliably operate your
network at 100Mbps, you must use Category 5 cable, or better
Data Grade. Make sure 4-paired wires are used.
