2. Functions and Wireless Link Mode

This chapter describes the major functions of the FLEXLAN DS540 series as a wireless LAN system and

the wireless link modes of the FX-D540-APDL along with configuration examples of networks available

in the wireless link modes.

Roaming Function

The roaming function maintains the connection to the LAN by automatically changing the access point

to which the user unit is connected when the unit moves. If access points are positioned so as to cover

the entire area where the wireless LAN is to be available, the user unit can be used from anywhere.

When the wireless link mode of a FLEXLAN-DS540 user unit is “Standard Infrastructure” or “Compatible

Infrastructure”, it is designed to continuously monitor the AP (access point) signal strength and change to

the AP that provides the most reliable communications.

In the following example, the signals from the APs do not cover the entire range in which the mobile

station UU1 moves and therefore the connection to the wired LAN is lost when UU1 is in position (2).

IP Tunneling Function (To be supported in the near future)

In TCP/IP, packets belonging to different network groups cannot normally be used. However, a

technique called tunneling or IP tunnel technology can be used to temporarily modify packets belonging

to different network groups so that they can be used. This technique can enable user units to

communicate with the wired LAN as usual even when connected via an AP from a different network

group.

The following example shows how user unit UU1, which belongs to network group A, can connect via a

router to terminal PC1, also in network group A, despite UU1 being connected to the LAN via AP2

which belongs to network group B.

MAC Address Filtering

MAC address filtering is the function to permit only the user units whose MAC address has been

registered for an AP to log in to the AP. Using this function can reject an attempt to log in to an AP by

an unidentified user unit not registered in the AP.

Figure 2.4 shows a sample image of connections under control of MAC address filtering. The example

assumes that the MAC addresses of UU1 and UU2 are registered in the MAC address filtering list for the

AP while UU3’s MAC address is not registered in the list. In this case, UU1 and UU2 can log in to the

AP but UU3 cannot. To permit UU3 to log in to the AP, the AP ’s administrator has to add the UU3’s

MAC address to the MAC address filtering list for that AP.

Bridge Packet Control

Bridge packet control is the function that allows an AP to pass only data from those network devices

whose MAC address has been registered for the AP to its clients. Using this function can restrict

communication between user units.

Figure 2.5 shows a sample image of connecting under bridge packet control. The example assumes that,

for bridge packet control, only the MAC address of the router is registered in AP1 and AP2. In this case,

UU1, UU2, and UU3 can exchange data with the external network through the router while they cannot

communicate with one another. When the router is connected to the Internet, UU1, UU2, and UU3 can

access the Internet while they cannot communicate directly with each other.

If the bridge packet control list for the AP contains no entry with the bridge packet control function enabled,

communication is unconditionally permitted between a wired unit and a wireless unit but rejected between

wireless units.

When the bridge packet control list for AP1 and AP2 contains no entry in the above example, UU2 and

UU3 can communicate with each other via AP1 and AP2 while UU1 and UU2 cannot.

Bridge packet control is suitable for a wireless LAN constructed in a public space.

Wireless Link Mode Descriptions

The AP has three wireless link modes. The available functions and network configurations differ

depending on the mode. Use the wireless link mode most suitable to the type of network you are

constructing. The factory default setting is simple mode. Chapters 4 and 5 describe the software setting

procedures for the wireless link modes and relat ed items.

Standard Infrastructure Mode

In this mode, each access point (AP) can accommodate user units (stations) to make up a network.

This mode allows the use of multiple AP's to configure wide-area wireless LAN's. All communication

between wireless terminals must go through an AP.

Figure 2.7. Standard Infrastructure Mode

In the above standard infrastructure mode, all wireless terminals communicate via unit type APs.

Roaming functions are supported, allowing logged in on any unit type AP.

For IP tunneling to work correctly, one of the APs must be setup as the master AP (See “Setting Item

List” in Chapter 5).

- Advantages

(1) Capable of accommodating APs as stations.

(2) If the IP tunneling function is used, communication can continue via different routers without

needing to change IP address.

(3) Allows log-in restrictions on unit type AP's (security function).

(4) Capable of improving security based on WSL (Wireless Security Link)

used. Roaming can be used to construct large scale wireless LANs.

IP t unneling

This function modifies the IP address so that units can connect to the desired network group even via.

It can be used in the Advanced Infrastructure and Standard Infrastructure modes.

Station AP connection

A station (unit type ST) indicates an AP managed (logged in) by another AP; it is used to serve as a

bridge.

SNMP

This function enables remote management by software that supports SNMP. Available in all modes.

Log collection function

This function lists the wireless terminals logged in to the AP and collects times and other event

information. See Chapter 6 for details.

2. Functions and Wireless Link Mode

DS540

MAC address filtering

This function enables connection of only the terminals whose MAC address has been registered.

Bridge Packet Control

This function allows the AP to pass only that data to terminals which comes from network devices

having a registered MAC address. Communication between wireless terminals can be rejected when

their MAC addresses are unregistered.

Data encryption

This function encrypts wireless data. For encryption, three security protocols are available: WSL

(Wireless Security Link: proprietary cryptography), WEP (Wired Equivalent Privacy) and AES. WSL

and WEP or WSL and AES can be used at the same time. Note, however, that devices using WSL and

those not using it cannot communication with each other.

IEEE802.1X(EAP -TLS)

This function performs authentication using digital certificates. After authentication, the AP

dynamically broadcasts the WEP key.

The function of IEEE802.1X cannot be used when the unit type of the AP is “station”.

Installation in a Network

This section describes how to install the FX-DS540-APDL to construct a network with improved

performance and discusses the general features and radio characteristics of the wireless LAN as well as

the guidelines for constructing the network.

Features of the Wireless Network

In general, the operation of a wireless network is the same as for most other types of LAN. The most

prominent feature of the wireless network is that it uses radio waves as its medium, eliminating the need

for cabling. The wireless network thus requires no cabling cost and has other advantages as listed below:

- Quick construction of a LAN

- Temporary installation of a LAN

- Higher flexibility in layout of connected PCs (terminals)

- Assured mobility of connected PCs (terminals)

On the other hand, the wireless network has the following drawbacks from the operational point of view

due to the nature of radio waves:

- Signal attenuation

- Signal interference

Also, although this unit does not require a radio license, it is subject to radio regulations.

3. Setup

DS540

Operating Environment and Radio Waves

When using this product to construct a network, install and operate it considering the radio environment

to optimize the performance.

Is allowed to use radio equipment at the installation location?

In some medical institutions and laboratories, radio-sensitive precision instruments are used and it may

be prohibited to use radio equipment.

Radio waves are attenuated.

Although a radio wave is attenuated naturally as it travels from its transmission source, it may also be

attenuated by an object existing in its way. Major obstacles that attenuate radio waves are as follows:

- Concrete wall

- Metal surfaces in the vicinity of the antenna

Obstacles blocking radio waves include metal walls and walls containing a metal firewall.

Strictly speaking, nearly all objects in the path of the radio waves (such as partitions or people) cause

some attenuation but these do not have a significant impact on network performance.

RSSI (Receive Signal Strength Indication) utility is available as a means of knowing the signal strength

of an incoming radio wave. Placing this product for a greater RSSI value makes the communication state

more stable. If the RSSI value is small and slightly moving the position of the product does not increase

the RSSI value, it indicates radio wave attenuation either to the distance or by an obstacle.

Pay attention to radio interference.

Radio interference means the reception of radio waves in the frequency band used by this network that

are generated by equipment that is not part of the network to which this product belongs. Listed below

are major examples of sources of interfering radio waves generated in general environments excluding

plants and factories:

- 5GHz (using by IEEE802.11a) or 2.4GHz (using by IEEE802.11b/IEEE802.11g) band wireless

networks that do not comply with IEEE802.11

- Using by IEEE802.11b/IEEE802.11g. Ex. microwave ovens, security gates (installed near the

entrances of some department stores and rental shops), copiers which give off the 2.4GHz electric

waves.

Where there is a large metal wall such as in a warehouse, the radio wave generated from the sender is

reflected, resulting in those radio waves reaching the receiver which have taken different routes (thereby

phase-shifted). This has the similar effect as the generation of interfering radio waves, possibly slowing

down data transfer.

Most of the interfering radio wave sources other than wireless networks have local and/or temporary

effects, not so affecting network performance. Rarely, however, the date rate is reduced and, in the

worst case, communication is disabled temporarily. In such cases, change the location of this product

and the channel used for communication. This may solve the problem.

3. Setup

DS540

Constructing a Network

This section gives some pointers and cautions relating to constructing a network using the AP and user

units, and provides some practical examples.

(1) Check the coverage (cover area) of the AP. To use the AP with two or more user units logged in an

infrastructure mode, all the user units must be installed within the cover area. The AP ’s coverage

varies with obstacles (concrete walls, iron doors, elevator halls, etc.). Note also that the number of

transmission/reception errors increases beyond a certain transmission distance.

When setting up the network, check the RSSI level then confirm that communication works

correctly with the application you plan to use. For a TCP/IP system, for example, you can use the

Windows PING command. To use PING, open an MS-DOS prompt window and enter the following

command. The example command is for an AP with an IP address of 10.168.132.15.

C:\WINDOWS>ping 10.168.132.15

(2) The maximum number of user units that can log in to an AP at one time is 254. However, remember

that the communication speed slows due to the increased loading as the number of user units for a

particular AP increases.

(3) This product can be set to one of the four channels according to the Wireless Telegraphy Act.

(4) If a pair of wireless terminals are communicating via a particular channel, no other communications

can use that channel within the range of the radio signal (the exception is broadcasting which

transmits to all terminals). As a result, communication speed tends to drop as the density of wireless

terminals increases although this depends to a large extent on how frequently the network is used.

(5) If the AP is connected to an Ethernet hub or similar, a unexpectedly large load can occur on the AP

if the Ethernet traffic is heavy and this may reduce the performance of the wireless network. This

can be solved by changing the hub connected to the AP to a switching hub (bridge).

(6) Setup the software in accordance with how the network will be used.

(7) The communication speed may also drop due to interference if two wireless terminals are located

close to each other. In general, maintain a gap of about 1m between user units, 3m between APs and

user units, and 3m between APs.

(8) The best performance is achieved from antennas if they are located in an open space free from

obstructions. Avoid locating antennas where they will be hidden. In particular, when

communication distance is an important consideration, it is recommended that you install antennas

in a high location with a clear view.

(9) Floors often contain steel beams or metal firewalls and therefore communication between floors is

often not possible.

3. Setup

DS540

Example 1 Use example

This example constructs a network with 48 user units. Although the small area to be covered means that

one AP should be enough, two APs are used to provide a backup and to ensure a reasonable level of

communication speed. If AP1 or AP2 is down, the roaming feature allows user units to log in to the other

AP and so provides a backup network connection. Also, as notebook PCs are often brought to the

meeting room and used to exchange data and access the server, and as the concrete walls of the meeting

room block radio signals and result in a low RSSI value, another AP is also located in the meeting room.

Each of the APs has a wired connected to the Ethernet network.

This example constructs a wireless LAN operating over three floors of a building. A different

department is located on each floor and these are separated by routers.

User PC1 belongs to the 3rd floor but sometimes takes his PC and works on the1st floor. As the IP

tunneling server function is enabled on the AP, PC1 can still perform operations such as sending and

receiving mail and accessing the 3F file server while roaming on the 1st floor away from the 3rd floor

router.

To keep the various APs separated, the APs on different floors are installed on opposite sides of the

building so that they are not directly above or below each other.

4. Setup Preparation

This chapter gives an overview of how to setup the AP and describes how to access the AP settings using

a web browser.

Setup Methods

Although the FX-D540-APDL can be set up precisely to construct an advanced wireless LAN

environment, there are two different setup methods available: web browser and TELNET.

The key features of each setup method are as follows.

WWW browser

- Provides an easy to use graphical interface.

- Setup can be performed remotely (via a LAN or modem).

- Independent of PC platform (type of OS, etc.).

- Requires that the network IP address of the AP be the same as the network IP address of the PC used

for setup.

TELNET

- Setup can be performed remotely (via a LAN or modem) and even from older PCs.

- This setup assumes that the IP address of the AP and that of the PC used for setup belong to the same

network group.

- It is necessary to connect the setting device to this product directly.

- Cumbersome text-only interface.

Setup Using a Web Browser

You can setup the AP software from a PC running a web browser via the LAN or a modem. As this

provides a graphical interface, setup using a web browser is much easier than using a TELNET.

The factory default IP address for the AP is listed on the underside of the case. You can use this address

to connect to the AP from a web browser but this requires that you change the IP address of the PC to be

in the same network group as the AP’s IP address (when finished, set the IP address back to its original

value).

Supported web browsers (recommended)

- Microsoft Internet Explorer 5.01 or higher

- Netscape Navigator 6 or higher

4. Setup Preparation

DS540

Connecting to the Web Browser PC

When using a web browser to setup the AP, you can connect via either a LAN or a modem. Use the

following procedure to connect the web browser.

Connecting via a LAN

(1) Connect the PC on which you will run the web browser to the same network as the AP.

Alternatively, you can use a UTP cable to connect the PC directly to the AP. In that case, use a

crossed-cable.

The connection will not work if you use a standard straight-through cable.

CAUTION

You may not be able to establish a connection if the web browser is setup to use a proxy. In this case,

change the setting to not use a proxy.

Remember to change the proxy setting back when you have finished setting up the AP.

Connecting to an FX-DS540-APDL

To connect the web browser to the AP, the IP address of the PC on which you run the web browser must

be in the same network group as the IP address of the AP. The factory default IP address set in the AP is

always in the class A network group starting with [10] (that is, 10.xxx.xxx.xxx). Accordingly, set the IP

address of the PC to also start with [10] ([IP 10.1.1.1, MASK 255.0.0.0], for example). Remember to set

the IP address of the PC back to its previous value after you have finished with the connection for setting

up the AP. You can also change and set the AP ’s IP address according to the PC being used for setup.

(1) Start the web browser

Recommended web browsers are Microsoft Internet Explorer 5.01 or later and Netscape Navigator

6.0 or later.

(2) After starting the web browser, enter the IP address of the AP in the URL field.

For example, if the IP address of the AP is [10.66.1.1], enter the following:

http://10.66.1.1 /

Refer to Chapter 5 below as you perform software setup.

(3) When connecting it to the product, input screen of the password is displayed. Enter the password.

No password has been set by factory default. When you log in at first, not input anything in the form

and then click the “Log-in ” button to log in.

(4) Click on [Setup] in the Top Menu and open the Setup submenu. Choose and click on the desired

item in the submenu to open its setup dialog box.

(5) After changing the setting of each item, press the [Send] button on the page to send the new setting

to the AP. The setting sent to the AP is temporarily retained in the AP.

To save temporary data retained in the AP, click on the [Save] button on the left menu or top page,

then choose “Yes” in the confirmation dialog box.

For the saved settings to take effect, click on the [Restart] button and choose “Yes” in the

confirmation dialog box to restart the AP.

To save settings and restart the AP at the same time, click on the [Save/Restart] button and choose

“Yes” in the confirmation dialog box.

For details of setup or Confirmation of status, refer to Chapter 5 to set up software.

Setup Using TELNET

Run Telnet on a PC connected within the same LAN to set up this product. As Telnet is a text based

program, it requires a bit complicated setup operations but it can be used for setup even on an old PC

with a browser which does not support setup through a web browser.

Figure 4.2. Example of TELNET Setting Screen

Connecting to an FX-DS540-APDL

For connecting the PC for setup to the AP using TELNET, the PC’s IP address and the AP’s IP address

must belong to the same network group. The IP address factory-set for the AP belongs to the class-A

network group beginning with 10, such as 10.xxx.xxx.xxx. For the PC to be used for setup, therefore,

assign an IP address beginning with 10 (for example, [IP 10.1.1.1, MASK 255.0.0.0]). After connecting

the PC to the AP and setting it up, restore the original IP address of the PC. The IP address of the AP

should be changed when it is set up.

You can also change and setup the IP address of AP depending on PC to set.

(1) Bring up the command prompt. In Windows 98 or Windows ME, choose “MS-DOS Prompt” from

“Programs” in the Start Menu. In Windows 2000 or Windows XP, choose “Command Prompt”

from “Programs” in the Start Menu.

(2) Connect it by using TELNET and then connect it to AP by using telnet command. For example, if

the IP address of the AP is [10.66.1.1], enter the following:

telnet 10.66.1.1

Saving the Settings File

Making a backup of the AP software settings file has the following benefits:

- If you have more than one AP and all APs have the same settings, you just need to setup one AP then

use the resulting settings file for the other APs. (However, as this sets the same IP address for all

APs, you need to change the IP address separately.)

- The old settings can be restored easily if a fault causes the settings file to be erased.

The settings file is stored the CF card with the following file name.

File name : CONFIG

If the MAC address filtering and bridge packet control functions are used, their settings files should also

be saved. The settings files are stored in memory on the AP with the following file names:

MAC address filtering --- MACFLIST

Bridge packet control --- BRGFLIST

Note that a file of LOGFLIST may be stored in the AP’s memory but it is not used as a setup file.

Using FTP to Backup the Settings File

(1) Run FTP to log in to the AP.

(2) Transfer the settings file.

When the MAC address filtering and bridge packet control functions are in use, MACFLIST,

LOGFLIST, and BRGFLIST are also transferred.

(3) Exit FTP.

The following example shows how to get the log file using the FTP command coming standard with

Windows.

Invoke the MS-DOS prompt or command prompt and follow the procedure below to get the settings file.

The example assumes the IP address as 10.168.132.15.

Restoring the Software Settings

Using this function has the following benefits:

- If you have more than one AP and all APs have the same settings, you just need to setup one AP then

use the resulting settings file for the other APs. (However, as this sets the same IP address for all

APs, you need to change the IP address separately.)

- The old settings can be restored easily if a fault causes the settings file to be erased.

Using FTP to Restore the Settings

(1) Run FTP to log in to the AP.

(2) Transfer the settings file(config).

When the MAC address filtering and bridge packet control functions are in use, MACFLIST, and

BRGFLIST are also transferred.

(3) Issue the reset request command(command : quote crst).

(4) Quit FTP. The AP will be restarted.

The following example shows how to update the firmware using the FTP command coming standard

with Windows.

Invoke the MS-DOS prompt or command prompt and follow the procedure below to restore AP settings.

The example assumes the IP address as 10.168.132.15.

C:\>ftp 10.168.132.15

ftp>put config

ftp>quote crst

ftp>bye

------------ (1)

------------ (4)

When the MAC address filtering function is in use, MACFLIST and LOGFLIST must be transferred

along with CONFIG. When the bridge packet control function is in use, BRGFLIST must be transferred

along with CONFIG. If both of the functions are in use, the above example is replaced by the following:

C:\>ftp 10.168.132.15

ftp>put config

Upgrading the Firmware

The AP firmware may be upgraded to resolve any bugs found in the software or to add new functions.

Contact CONTEC via our web site for details of the latest firmware.

The firmware is stored the AP memory with the following file name.

File name : apfirm.bin

Performing an Upgrade Using FTP

(1) Run FTP to log in to the AP.

(2) Change the transfer mode to binary.

(3) Transfer the firmware file.

(4) Issue the reset request command (quote crst).

(5) Quit FTP. The AP will be restarted.

The following example shows how to update the firmware using the FTP command coming standard

with Windows.

7. Troubleshooting

This chapter describes common problems that may occur with this product and what to do about them. If

any problems occur that are not described here, check to confirm that the re-occur, then contact the store

where you purchased the product.

When Communication Fails

Check hardware

- If connecting via the wired LAN, check that the LAN cable is connected correctly.

- Check that there are no obstructions in the way of this product.

Check software

- The FLEXLAN-DS540 series is designed to handle a variety of operating formats, and requires

software setting for each type of operation. Check that the settings are appropriate for the type of

operation, and check the format in which communication is being attempted. Also check DIP switch

settings.

- The terminals that cannot communicate with each other may have the same ESSID. Two terminals

with the same ESSID cannot communicate with each other.

- Check that the AP IP address and subnet settings have been entered.

- Check whether the wireless link mode has been set correctly.

To use the AP in an infrastructure mode, use the user unit in the infrastructure mode as well.

- Check whether communication is restricted by security functions.

- Check whether the data encryption setting is the same as that of the recipient.

Communication cannot be performed while data encryption is being switched between ON

(enabled) and OFF (disabled).

7. Troubleshooting

DS540

Check the peripheral environment and place of installation

- A nearby source of electromagnetic interference can prevent communicat ion. In general locations

(excluding factories) the following may be sources of electromagnetic emissions.

- 5GHz band not conforming to IEEE802.11(when using by IEEE802.11a) or 2.4GHz

band(when using by IEEE802.11b/IEEE802.11g) wireless network.

- Electric devices which give off 2.4GHz band electric wave - microwave oven, security gate (it

is a antitheft gate in the shop), copy machine and so on.

Most electromagnetic sources other than wireless networks are local and not continuous, and therefore

by moving the location of the unit and waiting briefly, communication may be possible.

- Sometimes communication is hindered by attenuation of electric waves. Attenuation occurs

naturally as distance from the source of transmission increases, but may also be caused by objects in

the path of the transmission. The objects primarily responsible for attenuation are the following.

- Concrete walls

- Metallic surfaces around this product

When You Cannot Perform Setup Using a Browser

- Check that you are using the correct IP address for the AP.

- Check that the IP address of your PC is in the same network group as the IP address of the AP.

- Use a recommended browser (Microsoft Internet Explorer 5.01 or later, Netscape Navigator 6 or

later)

- You cannot use a browser to communicate with the AP if the TCP/IP protocol is not installed on

your PC.

When the AP Will Not Start

Check the power LED

- Check whether the “POWER” LED is illuminated. If not, check the power cable and confirm that

the power plug and mains plug are correctly connected.

- Check whether the Power LED is flashing. If the power LED is still flashing more than 5 minutes

after the power is switched on, the problem may be an AP firmware failure. In this case, contact

your retailer.

Glossary

SQE(Signal Quality Error) (Heartbeat)

This uses the same signal line as the collision signal for the purpose of notifying the

transmitting terminal that the packets sent from the terminal are sent correctly over the

cable.

PPP(Point to Point Protocol)

A protocol for communicating using TCP/IP over a serial line.

IEEE(Institute of Electrical Electronics Engineers)

"I-triple-E," in volved in a wide range of fields from communications and computer to

medicine and biology, with primary activities related to publishing articles and

sponsoring conferences, but also recommending and setting of standards. The

organization sponsoring Committee 802, which is responsible for LAN related matters.

IEEE802.11/ IEEE802.11a/IEEE802.11b/IEEE802.11g

The wireless LAN standard established by the IEEE.

OFDM(Orthogonal Frequency Division Multiplexing)

OFDM is a modulation technique for transmission using different bandwidths. It is

characterized by immunity to fading and multipath.

MIB(Management Information Base)

The value of a MIB is determined by the Internet standard control information

structure.

SNMP(Sinmple Network Management Protcol)

A function necessary for network control, provides three functions: Get (acquire), Set

(modify), and Trap (notify event). Conceived as an easily installable control protocol

that places as little load on the network as possible.

Diversity

A method of using multiple antennas, and selecting the one with the best receiving

conditions.

Router

A device for relaying between LAN's. The router determines data addresses by the

combination of a network address assigned to the network and an individual computer

address. Used particularly in medium-scale and larger LAN systems with very large

number of clients, to reduce traffic (congestion) on communication lines.

Bridge

A device for relaying between LAN's. The bridge determines whether to relay data

based on the address of t he computer to which the data is being sent. It can be used to

connect networks having different protocols, or when data for broadcast to all

computers is received, can send this to all connected networks.

Brouter

A router with an added bridge function. When data received from one network cannot

be processed by the router because a different protocol is used, the bridge function can

be used to send the data on to the other network.

LAN(Local Area Network)

A network configured from mutual connections between computers within a limited

area. Also called an "intranet" or "business or regional data communications network."

RSSI(Receive Signal Strength Indication)

A numeric indicator of incoming signal strength.

Spectrum diffusion transmission

A method of transmission in which signals that are normally transmitted over a given

limited frequency band undergo narrow band modulation (primary modulation), then

again diffuse modulation (secondary modulation) to intentionally diffuse the signal

over a broad frequency spectrum.

DS(Direct Sequence)

A type of spectrum diffusion signal using narrow band modulation with phase

modulation, in which the diffusion is by means of phase modulation using a broad band

diffusion signal (pseudo random strings).

CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance)

CSMA is a method of avoiding collision by which wireless terminals listen before

transmitting and do not transmit if they can year transmissions from other wireless

terminals. CSMA/CA is CSMA plus additional collision avoidance functions.

Hidden Terminal Problem

When wireless terminals are farther apart then their electric signals can reach, or their

signals are obstructed by objects, neither may be able to receive the other's signals.

Any two such wireless terminals are said to be hidden from each other. In Ad Hoc

mode, because the carrier sense function is not effective between hidden terminals

there is a higher probability of collisions and throughput (the volume of information

sent in a given time interval) is reduced.

RTS(Reqest To Send)

In communication via AP, transmission is controlled by CSMA/CA plus RTS. In RTS,

a wireless terminal asks the AP if it is all right to transmit, and only transmits after an

OK-to-send acknowledgement signal is returned. This serves to avoid unnecessary

collisions when hidden terminals exist because hidden terminals cannot transmit.

Roaming

This term has the same meaning as roaming for a portable phone or PHS. The AP is in

the role commonly called the 'antenna/base station' for the phone or PHS, and the user

unit is in the role of the phone itself.

DS540

Peer-To -Peer

A network in which two or more nodes can communicate directly with each other

without going through another device.

AP(ACCESS POINT)

Access point. In the FLEXLAN DS540 series, the access point serves as a bridge

between a wired network and a wireless network and provides IP tunneling; it is

indispensable for the versatility and scalability of the wireless network.

User Unit

In FLEXLAN DS540 series, user unit means the device loading

FX-DS540-PCC/FX-DS540-PCC2/FX-DS540-PCD.

ESSID(Extended Service Set ID)

In the FLEXLAN DS540 series, the ESS ID is like a name assigned to the wireless

LAN network to which a unit belongs. The same name must not be given to more than

one wireless terminal. Conversely, a wireless network can be partitioned by using

different ESS ID names.

Channel

This has the same meaning as in TV and radio terminology. The 5.15 to 5.35 GHz band

(namely 36, 40, 44, 48, 52, 56, 60, 64, total : 8channels) and the 5.725 to 5.825 GHz

band (namely 149, 153, 157, 161, 165, : 5channles) used by this products is stipulated

by IEEE802.11a to be divided into a total of thirteen channles.

The 2.4 to 2.4835GHz band (namely from 1 to 11, total : 11channels) used by this

products is stipulated by IEEE802.11b/g to be divided into a total of eleven channles.

Radio transceivers different in channel cannot communicate with each other even when

they belong to the same network.
