Introduction

The Nokia C110 Wireless LAN Card and the Nokia C111 Wireless LAN Card are extended type II PC cards, offering a data transmission rate of up to 11 Mbit/s in a wireless local area network (LAN) environment. The Nokia C110 features two internal antennas for compact size. The Nokia C111 is equipped with internal antennas and two external antenna connectors.

The Nokia C110/C111 Wireless LAN Card:

• Complies with the IEEE 802.11b standard.

• Supports data rates of 1, 2, 5.5, and 11 Mbit/s.

• Operates at a frequency of 2.4 GHz using direct sequence spread spectrum

(DSSS) radio technology.

• Supports the Windows® 95, Windows® 98, Windows® Me, Windows® 2000, and Windows NT® 4.0 operating systems. For other supported operating systems, please check the Nokia Web site at www.forum.nokia.com.

Nokia’s wireless LAN cards enable you to wirelessly connect compatible laptop computers, hand-held devices, desktop PCs, and other devices with a type II or III PC card slot to a wired local area network through an access point. Instead of cables, radio waves are used to transmit and receive data over the air. With the Nokia C110/C111 you can:

• set up an infrastructure network where wireless stations communicate with wired and wireless stations through an access point. You can wirelessly access your company database, e-mail, the Internet, and other network resources, for example.

• set up an ad hoc network where wireless stations send and receive data directly with each other. No access point is needed, and as long as the stations are within range, you can, for example, share and exchange files.

The Nokia C110/C111 comes with an integrated smart card reader. Vital information, such as security keys and personal network profiles that make moving between networks easy, can be stored on a smart card.

Wireless LAN

The wireless LAN cards described in this document are approved for use in a wireless local area network.

The wireless LAN card employs the data transmission capabilities of a wireless LAN in order to send and receive data, to browse the Internet, and to establish connections with other computers, for example.

Data connections can be made from most locations where your wireless LAN card operates. However, it is recommended that you move the wireless LAN card to a location where the strongest possible network signal can be obtained. When the signal is strong, data transmission is efficient.

The following factors may impair wireless connections:

Noise

Electronic appliances and equipment can cause radio interference. Also in areas where wireless LAN cards are prevalent, other wireless LAN cards can impair the wireless connection.

Roaming

As the wireless LAN card user moves from one access point coverage area to another, the signal strength of the channel drops. As a consequence, the network may hand the user over to a coverage area and frequency where the signal is stronger. Due to varying network traffic loads, roaming may also occur when the user is stationary.

Electrostatic discharge

A discharge of static electricity from a finger or a conductor may cause erroneous functions in electrical devices. The discharge may result in unstable software operation. Network connections may become unreliable, data may be corrupted, and the transmission halted. In this case, end the existing connection (if any), stop the wireless LAN card, and remove it from the PC card slot. Then re-insert the wireless LAN card into the PC card slot and try connecting again.

Dead spots and dropouts

Dead spots are areas where radio signals cannot be received. Dropouts occur when the wireless LAN card user passes through an area where the radio signal is blocked or reduced by geographical or structural obstructions, such as concrete walls.

Signal impairment

Distance and obstacles can cause out-of-phase reflected signals that result in a loss of signal strength.

Low signal strength

Due to either distance or obstacles, the radio signal strength from an access point may not be strong or stable enough to provide a reliable wireless connection for communication. Therefore, to ensure the best possible communication, remember to consider the following points:

• Data connection works best when the wireless LAN card is in a stationary position.

• Do not place the wireless LAN card on a metal surface.

Important!

Warning: Do not use the wireless LAN card when the use of a wireless device

is prohibited or when it may cause interference or danger. Note that the wireless LAN card may cause similar interference as a cellular device and must not be used in areas where the use of a cellular device is prohibited.

Warning: Be careful when moving your computer so that you do not cause

damage to the protruding end of the inserted wireless LAN card.

Warning: In Europe, this equipment is intended to be used in the following EU

Member States: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and United Kingdom. This equipment can also be used in Norway and Switzerland.

Warning: Use the wireless LAN card in the specified countries only. Using the

wireless LAN card in any other country or with an incorrect country setting may be illegal.

Warning: This equipment operates at 2.4 - 2.4835 GHz. Note that in France

the use of this equipment is only allowed at the frequency band of 2.445 -

2.4835 GHz (channels 10, 11, 12, and 13).

Note: Transmitted data is not encrypted by the wireless LAN card by default.

For more information about security in data transmission, please visit www.forum.nokia.com.

Security

Security issues should always be carefully considered to ensure the secure transmission of data in both wired and wireless LANs. In current wireless systems, for example, access points need to authenticate wireless stations to prevent unauthorized access to the network. Authentication is a service that confirms the identity of an entity, such as a user or a computer, or confirms the origin of a transmitted message.

The Nokia C110/C111 supports the wired equivalent privacy (WEP) protocol to provide security equivalent to that of a wired local area network. The WEP protocol utilizes the RC4 algorithm with an up to 128-bit secret key, which encrypts data before it is transmitted over the radio waves. This provides protection against intruders and unauthorized access to the data. When the wireless stations in a wireless LAN wish to communicate using WEP, they must have possession of the same secret key.

The Nokia C110/C111 is equipped with an integrated smart card reader. Smart cards and smart card readers provide a tool for managing secure user

authentication in a wireless LAN. Smart cards also provide an easy way for users to carry an authentication device with them. On a smart card users can store important information, such as security keys and network profiles. The smart card reader reads the data stored on the computer chip and sends it to the network for processing. The smart card is protected by a PIN code; to access the contents of the smart card, you need to enter the correct PIN code.

Warning: Keep all miniature smart cards out of small children’s reach.

Antennas

The Nokia C110/C111 Wireless LAN Card is equipped with two internal antennas placed inside an extension box providing improved signal quality and coverage area. As with any other radio transmitting device, do not touch the antenna unnecessarily when the wireless LAN card is in use. Contact with the antenna affects the quality of the transmission and may cause the wireless LAN card to operate at a higher power level than otherwise needed.

Note: Make sure that the antenna is pointing towards the access point and

placed in an open area. Do not cover the antenna.

The Nokia C111 has two antenna connectors for attaching external antennas for coverage area extension. The Nokia C111 can be used with up to two external antennas at the same time. Use only the supplied antennas or an approved external antenna. Unauthorized antennas, modifications, or attachments could damage the wireless LAN card and may violate regulations governing radio devices.

If only one external antenna is used, best performance is obtained by connecting the external antenna to the right antenna connector of the wireless LAN card.

Right antenna connector

Figure 1 - Nokia C111

Warning:

Use only accessories approved by the wireless LAN card manufacturer for use with this particular wireless LAN card. The use of any other type of accessories will invalidate any approval or warranty applying to the wireless LAN card, and may be dangerous.

Caution: When you disconnect the cable of any external antenna, grasp and

pull the plug, not the cable.

Note: For availability of approved accessories, please check with your dealer.

Caution: In order to comply with FCC RF exposure

requirements for a mobile transmitter, a minimum separation distance of 20 cm must be maintained between the antenna and all persons during transmission.

Getting started

To access and to operate in a wireless LAN with the Nokia C110/C111 Wireless LAN Card, you need to specify a number of network settings. If wireless stations are to communicate with each other in the wireless LAN, the stations must share certain settings. You can leave most settings at their default value, or use the automatic option when applicable, unless, for example, the system administrator advises you to the contrary.

Note: When you have changed certain settings, the system may prompt you

to restart it. Restart your computer to enable the new settings.

Different wireless LANs require different settings. All necessary settings are configured when you create a network profile. A profile is a collection of settings needed for connecting to a wireless LAN. With the Nokia C110/C111 you do not need to remember these settings by heart or configure them every time you use your wireless LAN card. You can easily switch between networks, for example, from headquarters to field office, simply by selecting the appropriate profile. Any of the settings can be changed by editing the existing profiles. See “Profiles” on page 21 for more information.

Three profiles with pre-defined settings are automatically created during software installation. The Quick Infrastructure and Quick Ad Hoc profiles enable quick and easy access to a wireless LAN: you need not configure any network settings. The Quick Infrastructure profile is used for accessing public access zones or your corporate network. The Quick Ad Hoc profile is used for setting up a network where wireless stations communicate directly with each other without access points. When you activate either of these profiles, a list of available networks appears where you can select the network which offers the best signal strength and data rate for communication. The third pre-defined profile, Wired LAN, contains the original network settings needed for accessing the wired local area network. See “Using default profiles” on page 16 for more information.

Installation

For instructions on installing the Nokia C110/C111, please see the separate Installation guide on the CD-ROM.

Basic settings

The minimum set of parameters to be configured are listed below.

Note: All wireless stations within a wireless LAN must share the basic

settings if the stations are to communicate with each other.

Country

You must always configure the country setting according to the country where you are currently using your wireless LAN card. Using the Nokia C110/C111 Wireless LAN Card in any other country not specified, or with an incorrect country setting may be illegal.

The country setting can be configured on the General settings page.

Operating mode

The Nokia C110/C111 enables different types of communication in a wireless LAN. There are two operating modes to choose from: infrastructure and ad hoc.

Infrastructure

The infrastructure operating mode allows two kinds of communication:

• Wireless stations communicate with each other through an access point.

• Wireless stations communicate with a wired LAN station through an access

point.

Figure 2 - Infrastructure networking

The advantage of the infrastructure operating mode is that you can have more control over network connections because they pass through an access point. A wireless station can access the services that are available for a regular wired LAN by using an access point.

Ad hoc

In the ad hoc operating mode, wireless stations communicate directly with each other; no access point is required. Simply insert the wireless LAN cards into the stations, make the necessary configurations, and start communicating. Ad hoc networking is easy to set up, but communication is limited to stations that are within range.

Figure 3 - Ad hoc networking

Select the desired operating mode when you are creating a new profile with the Profile Wizard. If you want to change the operating mode later, go to the Profiles page and click Edit.

Network name

The network name is the name of the wireless LAN to which the card can connect. It is usually programmed into an access point by a system administrator. You should ask the system administrator for the network name.

You can save more than one network name for each profile. If you enter more than one network name, the names must be separated from each other by a semicolon, for example: Headquarters;Office4.

Within a network, there may be subnetworks that all have different names, for example: Office_wlan1, Office_wlan2, Office_wlan3, etc. One profile can be used to connect the wireless LAN card to all the subnetworks. The network name may include a special character, a wildcard *, which can be used as a place holder for one or more letters or numbers. By using the wildcard, you can specify Office_wlan* as the network name, and the wireless LAN card can be connected to any of the networks whose name starts with Office_wlan.

In the ad hoc operating mode, the users themselves give a name to the network.

Note: The network name can consist of up to 32 alphanumeric characters.

By default, the network name is case-sensitive. To change this property, go to the General settings page and select the Advanced tab. There you can clear the Case-sensitive network names check box.

If you want to change the network name later, go to the Profiles page and click Edit.

Channel

The Nokia C110/C111 operates in the 2.4 GHz frequency band. You need to specify a radio frequency channel on which the wireless LAN card is used. The selection of available channels may vary from country to country, as certain countries have a limited number of channels that can be used.

You can select the Automatic channel selection option when you are creating a new profile with the Profile Wizard: you are automatically allocated an available channel without needing to specify one. You can, however, also select the correct channel yourself. In that case, make sure that the wireless LAN card and the access point are using the same channel.

If you want to change the channel setting, go to the Profiles page and click Edit.

Connecting to a network

The Nokia C110/C111 Wireless LAN Card connects your computer automatically to the access point and network that offer the best quality for communications. If you move the computer to another location within the network and out of range of the access point, the roaming functionality will automatically connect your computer to another access point that belongs to the same network. As long as you remain within range of access points that belong to the same network, your computer will stay connected to the network.

Once you have installed the software for the Nokia C110/C111, you can connect to a wireless LAN. For instructions on installing the Nokia C110/C111, please see the Installation guide on the CD-ROM.

Insert the wireless LAN card firmly into the PC card slot of the computer. See Figure 4.

Figure 4 - Inserting the card

Caution: Note that the wireless LAN card is not inserted all the way into the

PC card slot and there is a gap between the protruding extension box and the computer. Do not use excess force when inserting the card.

2 Switch on your computer. 3 If you are using a smart card, enter the PIN code and click OK.

Note: If the dialog box asking for your PIN code appears before the

network logon dialog box, type the PIN code first.

4 Open the program by right-clicking the Nokia C110/C111 icon on the taskbar.

A shortcut menu opens. Click Manager window or Profiles.

5 The Profiles page opens. Under Profile selection, select the profile you want to

use with the wireless LAN in question. Click Apply. You may need to restart your computer. If you are about to connect to a new network and therefore need to create a new profile, or if you need to modify an existing profile, see “Creating new profiles” on page 22, or “Editing profiles” on page 23.

Note: In Windows 2000 and Windows NT 4.0, if you want to connect to a

wireless LAN when logging onto a domain, insert the wireless LAN card into your computer and switch on the computer, then wait until the small Nokia C110/C111 icon appears in the bottom right corner of the screen. After that you can type your user name and password.

Setting up and joining an ad hoc network

Ad hoc networks allow wireless stations to communicate directly with each other without any access points. The stations can, for instance, share folders. One user creates the ad hoc network and other users then join the network.

You can choose to use a password to protect the network from unauthorized users. Only those stations that have the correct password can join the network.

To start an ad hoc network:

1 On the Profiles page, select the Quick Ad Hoc profile and click Apply. 2 Give the ad hoc network a name. You can also define a password for the

network. Click Start.

3 Select an appropriate data rate: 2 or 11 Mbit/s. Note that all stations on an ad

hoc network must be using the same data rate. Click OK.

To join an ad hoc network:

1 On the Profiles page, select the Quick Ad Hoc profile and click Apply. 2 Select the network you want to join and click Join. If a password is used in the

network, type the password and click OK.

3 Select an appropriate data rate: 2 or 11 Mbit/s. Note that all stations on an ad

hoc network must be using the same data rate. Click OK.

Note: When you select a profile for ad hoc networking, the system asks you to

restart your computer if your network settings need to be changed. Restart your computer and then either start a network or select the network you want to join.

Tip: Create your own profile for ad hoc networking with the Profile Wizard if

you use the ad hoc operating mode frequently. This saves you from having to start a network each time and allows quicker access. See “Creating new profiles” on page 22 for more information.

Using default profiles

Three default profiles are created during the installation: Quick Infrastructure, Quick Ad Hoc, and Wired LAN. With these profiles you can easily and quickly

establish a network connection: you get a list of available networks and can join one without having to change the network settings manually. The Wired LAN profile contains the original network settings needed for accessing the wired local area network. Note that these profiles cannot be edited, deleted, or exported. The Wired LAN profile, however, can be updated to comply with the current wired LAN settings.

1 On the Profiles page, select the appropriate default profile and click Apply. If

your network settings need to be changed, the system asks you to restart your computer. In that case, restart the computer.

2 A dialog box with a list of available networks opens. Select a desired network

and click OK. The wireless LAN card joins the network.

The Administrator page is used by system administrators. The number of pages may vary depending on which pages were selected during installation. You can view the different pages by clicking the icons on the left icon bar.

Profiles

For the Nokia C110/C111 to operate in wireless local area networks, you need to configure certain settings for each network. For example, when you use the card in your office LAN, you need different settings from those of the LAN at an airport you are visiting. On the Profiles page you can configure the necessary settings and create network profiles for specific wireless LAN environments.

A profile is a group of wireless LAN specific and Windows networking settings that you need for accessing wireless LANs. Profiles enable easy transfer from one network to another without having to remember all the different settings. On the Profiles page you can also modify existing profiles and create new profiles. Profiles are stored to a hard disk or a smart card.

Selecting profiles

You need to select a network profile suitable for the wireless LAN in which you want your wireless LAN card to operate.When you insert the wireless LAN card into your computer, the card selects the profile last used as a default profile. If, however, you want to use another profile, you can either select it from the list of existing profiles or create a new one.

In the Profile selection area, there is a list of profiles from which you can select a profile with all necessary settings for a particular wireless LAN. If you have connected to a network previously, you can simply select the profile for that network and then click the Apply button. The profile that is currently active is indicated with a green check mark, while a profile that has been selected but is not yet activated has a frame around it. A profile which is stored on a smart card is indicated with a small smart card symbol. The name of the active profile is displayed in the Operating information area. See Figure 6 on page 20.
