INFORMATION
Congratulations on your CREWAVE Wireless LAN Access Point purchase!
If you want to install a networking system that is not only fast and powerful, but also
easy to set up and simple to maintain, it is natural that you should choose a
CREWAVE 11Mbps Wireless LAN Access Point.
The CREWAVE 11Mbps Wireless LAN Access Point(this “AP”) is the wireless
Access Point for the 802.11b compliant. This AP extends the range of your cabled
Ethernet network(a wired Local Area Network), providing easy network access to
mobile users and difficult to wire locations. So the AP can serve mobile wireless
stations, roaming between various locations within a network area.
Moreover, this AP provides excellent levels of security, robustness and roaming
features required for your business.
What is a Wireless LAN?
A Wireless LAN provides the same functionality of a Wired LAN, but it eliminates the
need to install networking cables and other networking equipment. Not only is a
Wireless LAN easier to deploy, but it also allows for “roaming.” For example, an
employee using a portable computer with a Wireless LAN PC Card, can roam from a
conference room to an office without being disconnected from the network.
What is IEEE 802.11?
The IEEE 802.11 specification is a Wireless LAN standard developed by the
IEEE(Institute of Electrical and Electronic Engineering) committee in order to specify
an over an air interface between a wireless client and a base station or Access
Point(AP), as well as among wireless clients. Like other IEEE 802 families, IEEE
802.11 specification addresses both Physical(PHY) layer and Media Access
Control(MAC) layer.
- IEEE 802.11 Physical(PHY) Layer
At the PHY Layer, IEEE 802.11 defines three physical characteristics for WLAN :
CREWAVE Wireless LAN PC Card

diffused infrared, direct sequence spread spectrum(DSSS), and frequency hopping
spread spectrum(FHSS). While the infrared PHY operates at the baseband, the other
two PHYs operate at the 2.4GHz ISM(Industrial, Scientific, and Medical)band, which
can be used for operating Wireless LAN devices without the need of end-user licenses.
In order for wireless devices to be interoperable, they have to be conforming to the
same PHY standard.
- Media Access Control(MAC) Layer
The IEEE 802.11 MAC Layer is mainly concerned with the rules for accessing the
wireless medium. There are two network architectures defined : Ad-hoc Network and
Infrastructure Network.
Which one should I use?
- Ad-hoc Networking
Also called “Peer-to-Peer” networking, this model is the easiest to deploy and is
ideal for small offices. As a user on this type of network, you are able to share files
with other employees, print to a shared office printer, and access the Internet via a
shared modem. However, with Ad-hoc networking your computer is only able to
communicate with other wireless computers that are within range and in your wireless
workgroup.
- Infrastructure Networking

The key difference between a structured wireless network and an Ad-hoc wireless
network is the addition of one extra element – an Access Point. Unlike “Peer-to-Peer”
networking, where networked computers send data directly to each other, structured
networked computers communicate with each other through a dedicated Access Point.
All data transmitted between two computers, (clients) on the wireless network passes
through the Access Point. Additionally, the Access Point on the wireless infrastructure
network can provide access to an existing wired network. This link allows computers
on the wireless network to access the wired network’s resources and tools, including
Internet access, email delivery, file transfer, and printer sharing.
* Roaming
In an infrastructure network, this is when a wireless PC moves out of range of the
previously connected Access Point and connects to a different Access Point. By
physically spreading Access Points throughout the network environment, clients can
always be connected regardless of where they are located or roam.

PREPARATION
To achieve optimum performance of your CREWAVE Wireless LAN:
Evaluate the area in which the network will be arranged and plan the layout
CREWAVE Wireless LAN PC Card

accordingly. The key factors in the layout of your CREWAVE Wireless LANs are the
evaluated area in which the network will be deployed and plan the layout accordingly.
The key factors in the layout of your LANs are the distance between the Access Points
and the spatial and structural design of the network area. Test the performance of your
infrastructure network by moving the positions of the Access Points. In most buildings,
wireless LAN cards maintain a range of 100 to 300 feet. This distance varies depending
on the thickness and composition of the walls.
In some situations, you may need to move a computer or add an Access Point in the
networked area to achieve optimum performance or range. Consider the following
factors when choosing locations for the Access Points:
- Radio waves pass through walls and glass but not through metal. You may
find that reinforcing metal in the structure of some concrete walls blocks the
signal.
-
Open spaces generally provide the best range, but surrounding large metal
walls may cause reflections that reduce the data rate.
Floors typically have steel girders and other metal material that may block radio waves
-
from traveling between floors.
Notice
1. Connect the CREWAVE 11Mbps Wireless LAN Access Point(this “AP”) to a
grounding type AC wall outlet(100~240 VAC) using the standard power cord as
supplied with the unit.
2. Placement must allow for easily disconnecting the AP from the AC wall-outlet.
3. Do not cover the AP, or block the airflow to the AP with any other objects.
4. Keep the AP away from excessive heat and humidity and keep the AP free from
vibration and dust.

INSTALLATION
1. Choose the place with the consideration of power supply and network connection to
install the Access Point on a flat surface such as a table or cabinet.
2. Plug in the power cord to the power outlet and adapter. Plug in the DC output to “DC
in”. Make it sure that the Power LED is on. If the Power LED is not on, please check
the connections of the power cord.

Use the supplied power adapter and the standard power supply.
3. Attach Ethernet cable to the RJ-45 Connector. Make it sure that the Ethernet LED is
on. If the Ethernet LED is on, you can use the existing network with the Access Point ;
otherwise check the cable connections.
4. You can place the AP on a flat surface as a table or cabinet by the fixed Stand.
AP Manager Utility
Verify that all CREWAVE 11Mbps Wireless LAN Access Point ( this “AP”) have been
properly installed, and have been powered-on.

4. Setting the channel. Channel index should be between 1 and 14(differs from country
to country). If you have nothing more to set after consulting with Network
Administrator, click the “OK” button.
Notice
If you are operating two or more Access Point in the adjoining cells, keep the appropriate
channel distance to avoid the interference. We recommend you to keep the distance of at least 3
channels in the adjoining cell.
5. (Optional) Click the “Encryption” button. Encryption uses a 40bits key to control the
network access.

wireless data communications to the users.
Please keep the password at a safe place or keep it where it may not get lost.
6. Click the “OK” button after setting “Encryption”.
7. In the “IP Setting” Item, set a IP Address and Subnet Mask after consulting with
Network Administrator for normal Network. Click on “OK”.
