4.1 Application
4.1.1 Ad-hoc configuration
An Ad-Hoc wireless LAN is a group of computers, each equipped with one TWL-C11 adapter, connected as an
independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured at the same radio
channel. Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.

Ad-Hoc Configuration
4.1.2 Infrastructure configuration
Access Point provides access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is
called an Infrastructure configuration. A group of TWL-C11 PC users and an Access Point construct a Basic
Service Set (BSS). Each TWL-C11 PC in this BSS can talk to any computer in the wired LAN infrastructure via
the Access Point.
Infrastructure configuration not only extends the accessibility of a TWL-C11 PC to the wired LAN, but also doubled
the effective wireless transmission range for 2 TWL-C11 PCs. Since Access Point is able to forward data within
its BSS, the effective transmission range in an infrastructure LAN is doubled.
BSS ID is, in essential, the ID of each independent TWL-C11. All TWL-C11 PCs configured without roaming
options in this independent BSS must be configured with BSS ID of that Access point. Check your Access Point
for its BSS ID or use the Access Point Browser Utility program.

4.1.2.1 Roaming
An Infrastructure configuration also supports roaming capability for mobile workers. More than one BSS can be
configured as an Extended Service Set (ESS). On account of a continuous connection to the network, users
within this ESS could roam freely. All TWL-C11 PCs and Access Point within one ESS must be configured with
the same ESS ID and at the same radio channel.
Before setting up an ESS for roaming, it would be helpful to improve the performance by choosing a feasible radio
channel and right places for Access Points.

network.
Q3
Does the AP have
provision for external high
gain antenna?
For what do the AP use two
Q4
antennas
Q5
What external antenna
1 - Keep the area around the antenna clear from materials that could block
radio transmission, such as metal objects, electronic devices, and cordless
telephones.
- Change the direction of the antenna slightly .
- Move your notebook computer a few inches to find a better signal.
2 Use you site survey utility (by w ireless LAN Card utility) to survey a better
location and orientation for a network connection.
1 Verify that the adap ter Wireless LAN Service Area ID matches the access
point ID
2 Verify that the adap ter Data Rate is configured properly for the access
point.
The AP has two connectors for external antennas.
This is the antenna diversity, it can increase the receive sensiti v it y of
Access Point.
It is SX connector. SX to SMA adapter is available
connector type? e.g. SMA
or reverse polarity SMA?
It is possible to connect two
Q6
directional antennas to both
Ap's. How is it might work
What about operating range -
Q7
450 m. ? What kind of
antennas do you used. May be
you have some good supplier
of external antennas which
could extend a operating
range?
Q8
Does buildi ng to building
mode support Multi-point to
Multi-point with repeating
capability?
Q9
Will the AP, in 'normal'
mode, support Routing
between different
networks?
You can attach certified antenna with the same connector (SX type) with
AP
Based on specification, the power margin can support communication
distance as long as 450 m in free space theoretically. But due to the fading
loss of atmosphere, the practical link distance of line-of-sight will be around
150 ~ 300 m (depends on weather, surroundings and antenna orientation).
Of course, this range can be extended by directional antenna.

Point-to-Point Protocol over Ethernet (PPPoE) relies on two widely accepted
standards: PPP and Ethernet. PPPoE is a specification for connecting the users
on an Ethernet to the Internet through a common broadband medium, such as a
single DSL line, wireless device or cable modem. All the users over the
Ethernet share a common connection, so the Ethernet principles supporting
multiple users in a LAN combine with the principles of PPP, which apply to
serial connections. PPPoE is upper layer protocol, and can be supported by our
WLAN products
This feature is handled by server, but not WLAN. That means if your sever
support it, it has no problem with WLAN.
Yes, we are planning to add web server function into AP, but the schedule is
not determined yet.
After you change IP, please make sure you download this change.
Save the configuration by selecting “Download Changes” under the
“File” menu. The IP address of the access point has now been set
permanently.
There are two possibilities.
(1) The default IP setting is the same for each AP. Connecting
two or more AP's simultaneously onto LAN will resul ts the
confli ct pr ob le m . Pl ea s e mo dify the IP set ting by SNMP (mak e
sure no other AP with the same IP on the LAN you connect) or
APUtility first.
(2) If you can find the AP by SNMP but can not connect to it,
this is caused by the conflict between IP & MAC.
Please follow below steps to resolve it.
Please plug the USB cable to the Access Point USB port. Run
the Bridge APUtility and select the “Configuration” button. You
will see the MAC address at first line.
Follow the steps below giving the Access Point a temporary
address at the beginning (Step A) and saving the IP address
through the SNMP Manager application (Step B).

Access Point Ver1.1
User’s Manual 30/08/2001
Step A:
1. Connect an Ethernet station and the Access Point on the
same subnet. The simplest way to accomplish that is to connect
the Access Point and the Ethernet station to the same hub. You
need to check if the station IP address and the Sub-net mask
are configured properly. Also the new IP address for the Access
Point must correspond to the Subnet mask.
2. Open a MS-DOS Prompt window and enter a static route
in the arp table for the new IP address you want to assign.
Use the arp -s command to do that: arp -s "new-IP-address"
"AP-MAC-address"
For example: arp -s 10.170.254.27 00-00-22-22-22-25
3. Ping the Access Point, using its new IP address.
For example: ping 10.170.254.27
4. If you get a ping reply, then the IP address has been
temporarily set. In order to set it permanently you need to
proceed to Step B without powering off the Access Point.
Step B:
1. Open the SNMP Manager application.
2. Connect to the access point by selecting the “Connect
AP-Bridge” option under the “File” menu. Type the IP address
of the access point (which has been temporarily set in Step A)
in the panel which appears, type “public” at the Community
field, and then press OK. The SNMP Manager will inform you
that the access point has been found and that all the
configuratio n valu e s ha ve bee n r etrieved.
3. Under the “Setup” -> “Bridge” submenu, select “IP
Configuration”. Type the IP address of Step A in the
configuration window that appears. Confirm the validity of the
other values (Ethernet Address and IP Mask) and press “OK”
4. Save the configuratio n by selecting “Download Changes”
under the “File” menu. The IP address of the access point has
now been set permanently.

7 GLOSSARY
Access Point - Any entity that has station functionality and provides access to the distribution services, via the
wireless medium (WM) for associated stations.
Ad-Hoc - A network composed solely of stations within mutual communication range of each other via the
wireless medium (WM). An ad hoc network is typically created in a sponta neous manner. The principal
distinguishing characteristic of an ad hoc network is its limited temporal and spatial extent. These limitations allow
the act of creating and dissolving the ad hoc network to be sufficiently straightforward and conven ient so as to be
achievable by non-te chni cal users of the network facilities; i.e., no specialized technical skills are required and little
or no investment of time or additional resources is required beyond the stations that are to participate in the ad
hoc network. The term ad hoc is often used as slang to refer to an independent basic service set (IBSS).
BSS (Basic Service Set) - An Access Point associated with several wireless stations.
ESS (Extended Serv ice Set) - More than one BSS can be configured as an Extended Service Set. An
ESS is basically a roaming domain.
Ethernet - A popular local area data communications network, originally developed by Xerox Corp., which accepts
transmission from computers and terminals. Ethernet operates on 10 Mbps baseband transmission over shielded
coaxial cable or over shielded twisted pair telep hone wire.
Infrastructure - The infrastructure includes the distribution system medium (DSM), access point (AP), and portal
entities. It is also the logical location of distribution and integration service functions of an extended service set
(ESS). An infrastructure contains one or more APs and zero or more portals in addition to the distribution system
(DS).
PCMCIA (Personal Computer Memory Card In t e rnational Association) - It develops standards for PC cards,
formerly known as PCMCIA cards, are available in three “types” which are about the same length and w idt h as
credit cards, but range in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These cards
can be used for many functions, including memory storage, as landline modems and as wireless LAN.
Roaming - A function that allows one to travel with a mobile end system (wireless LAN mobile station, for example)
through the territory of a domain (an ESS, for example) while continuously connecting to the infrastructure.
RTS (Request To Send) Threshold – Transmitters contending for the medium may not hear each other.
RTS/CTS mechanism can solve this “ Hidden Node Problem”.
Wired Equivale nt Privacy (WEP) - The optional cryptographic confidentiality algorithm specified by IE EE 802.11
used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired local area network
(LAN) medium that does not employ cryptographic techniques to enhance privacy.
