Introduction
The GW-AP11S is a bridge that interfaces between a wireless LAN network
and an existing Ethernet network. By using the GW-AP11S/AP11T Access
Point, you can seamlessly establish and integrate a wireless LAN network
into your existing Ethernet network and resources therein. The Access Point
complies with IEEE802.11 and IEEE802.11b, and supports data transfer at
11Mbps/5.5Mbps/2Mbps and 1Mbps. As the device supports Roaming,

Note:
After you have modified any of the parameters in each tab, be sure to click
on the Apply button before moving to another tab or exiting the window
(see below).
System
This tab will appear right after you have logged in to the system. The tab
displays system information of the access point.
Firmware Version:
Displays the version of the firmware that is currently installed on the access
point.
Regulation Domain:
Displays both the wireless communication standard currently supported by
the AP and its coverage area
MAC Address:
Indicates the unique MAC address that has been assigned to this particular
access point 00-90-CC.
wireless Setting
This tab allows you to modify the function parameters of the access point.
Access Point Name
Enter the desired name for this access point namely GW-AP11T (or GW-AP11S).
Wireless ESSID
Be sure to enter an ESSID if you wish to use the product as an access
point. An ESSID is used to connect a wireless client to a specific AP.
Operational Rate Set
You can select from among 4 speed settings, namely Auto, 11Mbps,
5.5Mbps, 2Mbps and 1Mbps.
Wireless Channel
The parameter indicates the channel used by the access point. Any of the
fourteen channels (Ch. 1 - Ch. 14) may be selected. When using two or
more access points in the same area, make sure that each channel is
eparated by at least four channels. (Ex. you may use Channel 1, 6 and 11,
but may NOT use consecutive channels such as Channels 1, 2 and 3)
Operational Mode
The access point supports the following four operational modes:
Access Point Mode:
Select this mode to use the access point in the standard IEEE802.11b station
mode.
4-1 Access Point Mode
26
GW-AP11S/AP11T
25
GW-AP11S/AP11T
Access Point Client Mode:
This mode is used to incorporate a PC with no wireless support into a
wireless LAN. The RJ-45 port on the AP is directly connected to the
Ethernet port on a PC.
4-2 Access Point Client Mode
WBridge Point to Point Mode:
This mode enables AP-to-AP communication via a hub directly attached to
each AP.
4-3 WBridge Point to Point Mode
28
GW-AP11S/AP11T
27
GW-AP11S/AP11T
WBridge Point to MultiPoint Mode:
This mode is used to enable AP-to-AP communication when 1)the AP
are
too far away from each other or 2)the AP'
are separated by materials that
block wireless communication. An AP configured to Multi-Point mode is
placed between two AP'
to relay radio waves.
4-4 WBridge Point to MultiPoint Mode
Preferred BSSID
Enter the MAC address of the access point to which AP'
set to Single Point
mode connect (see below).
4-5 Preferred BSSID
Advanced Button:
Click on this button to configure advanced options of wireless
communication. In each field,be sure to assign a value that is most
appropriate for the network environment in which the access point is used.
Fragmentation Threshold:
All packets are segmented so that their sizes fall below the value specified
as Fragmentation Threshold. Just like Ethernet, one-to-one communication
is performed in wireless LAN. Lowering the fragmentation threshold will
increase the chance that all clients on the wireless network can
communicate. At the same time, however, it will reduce throughput due to
increased overhead.
Increasing fragmentation threshold will improve throughput. Nonetheless,
this change will increase the amount of time that a client occupies a
communication, reducing the chance that other client can perform data
communication.
30
GW-AP11S/AP11T
29
GW-AP11S/AP11T
RTS Threshold:
Any attempt to transmit a packet whose size exceeds the RTS threshold will
cause the AP to enable the RTS/CTS function. RTS/CTS is helpful when
there are
hidden" terminals on the wireless network. Hidden terminals
here refer to terminals whose existence cannot be confirmed on the same
wireless network.
Just like Ethernet, one-to-one communication is performed in wireless
LAN. Clients which can only communicate with their nearest access points
(clients which cannot directly communicate with each other) can not
recognize whether or not their access points are currently communicating
with other clients. This situation may lead to a loop in which a client
continuously sends packets to its access point while the AP is
communicating with another client (thus incapable of receiving the
packets). In this case, packets transmitted to the AP are entirely lost. The
RTS/CTS feature can solve this problem. When RTS/CTS is enabled, the
first client sends an "RTS", or a request to the AP asking for its permission
to send packets. Upon receipt of RTS, the access point transmits a CTS
which contains conditions on packet transmission. Since other clients can
also receive the CTS, clients beyond the communication range of the first
client can now recognize the first client. Furthermore, clients that receive
CTS (and conditions on packet transmission therein) acquire the ability to
communicate with an AP WHILE the AP IS NOT communicating with
other clients, improving the overall throughput.
Beacon Period:
This parameter specifies the time interval of beacon signals that are sent
from an access point. Clients connect to AP
which transmit beacon
signals in good condition. The shorter the beacon period, the shorter the
time required by clients to recognize an AP. A short beacon period also
allows the system to perform Roaming more quickly, but the parameter
affects data transmission time as well.
Preamble:
The parameter configures the preamble portion of packets. A preamble is a
signal used to synchronize the transmission timing between packets. Yo u
may select between Long and Short.
IP Config
Use this tab to configure the IP parameters of the access point.
IP Address:
Use this option to assign an IP address to the access point. You must use a
unique IP address which is not used by any other node on the same network.
Namely is 192.168.0.1
Subnet mask:
Specify the subnet mask of the access point. Namely is 255.255.255.0
Gateway:
Enter the IP address of the default route.
DHCP Client:
Enable this parameter to let the access point obtain an IP address directly
from a DHCP server. Disable it if you wish to enter a fixed IP address.
