Installation of a driver

Installation in a network

This section describes how to install the FLEXLAN-DS110 series 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

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

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.

FX-DS110-PCC, FX-DS110-PCC2

15

Installation of a driver

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 wall

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

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.

Note!

Pay attention to radio interference.

Radio interference with this product indicates any disturbance to reception, caused by that radio wave in the frequency band of this product which is generated outside the local network. Listed below are major examples of sources of interfering radio waves generated in general environments excluding plants and factories:

- 2.4 GHz band wireless network

- Other sources

Microwave ovens

Security gates

(Installed near the entrances of some department stores and rental shops)

- Copiers

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.

16

FX-DS110-PCC, FX-DS110-PCC2

Installation of a driver

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.

Radio interference by a wireless network can be removed by changing the channel used. Note, also, that dividing the same network into groups different in channel may increase the data rate.

Constructing a network

Given below are the guidelines and notes on constructing a network:

(1) The operating distance of the FX-DS110-PCC/FX-DS110-

PCC2 between the AP and user unit is about 150 m in indoor space with no obstacle or about 50 m in indoor space with few obstacles.

(2) This product enables communication via a total of 11(FCC model) or 13(CE model) channels from channels 1 to 11 or 13.

Channels selected at intervals of five consecutive channels can be used for communication without mutual radio interference

(except channel 11). When more than one channel is used, radio waves can be utilized most efficiently using channels 1, 6, and 11.

(3) The operation mode and software settings such as ESS ID must be selected depending on the operation form. (See Chapter 5.)

(4) The operating range for communication with another terminal is about 50 m in indoor space free of radio wave attenuation caused by an obstacle or radio interference, covering almost the entire area of small- and medium-scale offices and plants.

Note, however, that extending the communication distance beyond a certain degree increases the number of transmission and reception errors.

FX-DS110-PCC, FX-DS110-PCC2

17

Installation of a driver

(5) When installing the PC Card, use the FLEXLAN-DS110 utility to check the RSSI value. In general, a remote party’s RSSI value of 70 or more assures stable communication. Even when the RSSI value is 70 or more, however, communication may not be stable, due to multipath for example, depending on the operating environment. Communication cannot be performed normally when the RSSI value is 50 or less.

After checking the RSSI value, run some applications that you usually use to check whether actual communication can be performed. In the TCP/I environment, for example, you can use PING in Windows. To ping, invoke the MS-DOS prompt and enter the PING command as shown below. In this example, the IP address of the target AP is 10.168.132.15.

C:\>ping 10.168.132.15

(6) Wireless terminals placed near to each other may fail to communicate with each other because of mutual interference.

Allow a minimum spacing of 1 m between user units and that of 3 m between each AP and user unit.

(7) When this product is used in the ADHOC (Simple) Mode, network performance is degraded unless all the terminals exist within the operating range for communication. (See "Hidden

Terminal Problem” in Chapter 7.)

Operation of the FLEXLAN-DS110

This section describes the types of networks configurable with the

FX-DS110-PCC/FX-DS110-PCC2, using basic examples. This product has two operation modes: ADHOC (Simple) Mode and

Infrastructure (Standard/Brouter) Mode for different network models. To construct a network with the FX-DS110-PCC/FX-

DS110-PCC2 only, use it in the ADHOC (Simple) Moe. When the

FX-DS110-APE, the AP (access point) in the FLEXLAN-DS110 series, is used with the

FX-DS110-PCC/FX-DS110-PCC2, use it in the Infrastructure

(Standard/Brouter) Mode.

Infrastructure (Standard , Brouter) Mode

In this mode, communication is performed always via the AP. The

AP has features (100BASE-TX and 10BASE-T) for connection to

Ethernet, enabling connection between the wireless and wired networks. The AP has advanced features such as routing and roaming and allows you to perform all setup and management easily from within the web browser over the LAN. As the AP has the SNMP agent feature, network management software such as an option of “SNMPc” can be used for management.

ADHOC (Simple) Mode

In this mode, all wireless terminals communicate with one another on a par basis. Since wireless terminals communicate directly with each other, the most part of setup at installation is not required and faster communication can be expected than in the APcentralized configuration. When installing the terminals, place them all within their operating distance for communication (to prevent the hidden terminal problem). In the following example, the terminals can be connected to Ethernet via the AP (operating in simple mode). Although the network can be constructed only with the FX-DS110-PCC/FX-DS110-PCC2, no terminal can be connected to Ethernet in that case.

Troubleshooting

When Communication Fails

Check this section if communication is disabled while the driver has been installed normally.

Check hardware

- Check if the antenna is loose or if there is any shielding object covering the antenna.

- Check whether the PC Card has been plugged deep into the PC

Card slot.

Check software

- Check whether the operation mode has been set correctly. For communication with the AP, also check its settings. To use the user unit in the ADHOC (Simple) Mode, place the AP in the simple mode. To use the user unit in the Infrastructure

(Standard/Brouter) Mode, place the AP in any mode other than the simple mode.

- Check whether the ESS ID is the same as that of the recipient.

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

- Check whether the driver has been installed normally. Check the properties of the “CONTEC FX-DS110-PCC”, “CONTEC

FX-DS110-PCC2” under Network Adapters in Device Manager.

- Check whether the channel being used matches that of the recipient.

Check the peripheral environment and place of installation

- A nearby source of electromagnetic interference can prevent communication. In general locations (excluding factories) the following may be sources of electromagnetic emissions.

- Another wireless network using the 2.4 GHz band

- Microwave ovens

- Security gates

- Copiers

- Elevator motors

Most electromagnetic sources other than wireless networks are local and not continuous, and therefore by moving the location of the unit (the PC containing this product or the recipient) and waiting briefly, communication may be possible.

FX-DS110-PCC, FX-DS110-PCC2

39

Troubleshooting

Interference caused by a wireless network can be avoided by changing the channel used. Note, also, that dividing the terminals in the same network into groups different in channel may improve the data rate.

- 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 antennas

Glossary

IEEE (Institute of Electrical and Electronics Engineers)

"I-triple-E," involved 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.

SNMP (Simple Network Management Protocol)

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.

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."

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-DS110 series, the access point is used as a bridge between wired and wireless networks and provides advanced features such as the inter-segment brouter function and IP tunneling, serving as an indispensable component for a versatile and large-scale wireless network.

User Unit

In the FLEXLAN-DS110 series, the user unit indicates the

FX-DS110-PCC/FX-DS110-PCC2 or the unit containing it.

42

FX-DS110-PCC, FX-DS110-PCC2

Appendix

Roaming

This means the same as roaming of a mobile telephone or PHS.

The AP serves as the component commonly called as “antenna/base station” in mobile telephone and PHS terminology; the

FX-DS110-PCC/FX-DS110-PCC2 serves as the telephone itself.

IP tunneling

One of the features of the FX-DS110-APE. Using this feature enables mail transmission and reception and database access without changing the PC settings even at a roaming destination beyond the router.

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.

FX-DS110-PCC, FX-DS110-PCC2

43

Appendix

RTS (Request 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.

RSSI (Receive Signal Strength Indication)

A numeric indicator of incoming signal strength.

ESS ID (Extended Service Set ID)

In the FLEXLAN DS110 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 term has the same meaning as a television or radio channel.

In the ISM band used by this product, the IEEE 802.11 standard provides for division into 11(FCC model) or 13(CE model).

channels numbered 1 to 11 or 13. Even on the same network, wireless devices operating on different channels cannot communicate with each other.

Multipath

Multiple versions of a radio wave emitted to be used for communication, which are received after being reflected by buildings and walls. Some of them are received after being reflected several times repeatedly. A strong multipath effect results in distortion of the signal in the directly received radio wave, degrading the communication quality and disabling stable communication
