Getting Started

Checklist

Make sure the following items are in the box when you unpack it:

• Protective case for storing the GC79

• GC79 PC Card

• Quick Start Guide

• CD-ROM The CD contains: drivers, software, documentation and a readme file.

System Requirements

This section lists the network subscriptions, hardware and software requirements for running the GC79 PC Card.

Wireless LAN Connection

In order to use your GC79 as a wireless LAN adapter for a corporate network, you must have the appropriate access and log-on rights. Contact your corporate IT support function to arrange access.

For access to the Internet, you will require the appropriate subscription or one-off usage login from your service provider.

Network and Subscription

The network subscription you use in conjunction with your GC79 depends on the functions and features your network operator can provide. Contact your network operator or service provider to make sure the options you require are available. Make sure that data options are included in your subscription, as these are usually optional services.

Note:

Mobile operators often provide a number of connectivity options via GPRS such as WAP and Internet. Verify the service you require, such as Internet, email or corporate VPN (Virtual Private Network) service is available through your mobile operator and enabled on your subscription.

The functionality of the different subscriptions available from networks operators are discussed below:

Circuit Switched Data (CSD)

CSD is the original GSM network data transfer method, used in the past for WAP. Almost all GSM networks have this capability at 9.6 kbps. It is possible for the network to upgrade the speed to 14.4 kbps. The GC79 operates at this higher speed where available.

8 Getting Started

Hardware

High Speed Circuit Switched Data (HSCSD)

HSCSD is an enchanced GSM network capability offered by some network operators. It enables circuit switched data connections to run at a higher data speed, using more than one wireless ‘timeslot’ for the data transmission. This is ideal for providing a faster connection to existing corporate or ISP dial-up facilities. The preferred connection speed is selected when you define the connection using the Connection Wizard.

General Packet Radio Service (GPRS)

GPRS is a new network connection which provides “always on” mobility. The connection set up is fast and, once connected, applications may send and receive data whenever required. In today’s GPRS networks, the GC79 receives data at speeds up to 53.6 kbps and transmits at speeds up to 26.8 kbps.

Short Message Service (SMS)

The PC can send and receive SMS text messages using the SMS Messages screen in the Wireless Manager, see Wireless Manager SMS Messages Screen on page 51, for more details.

You will need:

• A PC that has the minimum specification recommended by Microsoft to run the version

of Windows

installed on it.

• A 32 bit type II PC Card slot.

Sharing an Internet Connection

To connect a group of computers using a shared Internet connection, select one of the desktop computers to serve as the host computer (all other computers are called clients).

The host computer is the only computer that connects directly to the Internet. It is recommended that the desktop computer having the fastest microprocessor and the most memory is used as the host computer.

The host computer must be running either the Windows 2000 or Windows XP operating system.

Connection sharing requires that the host computer has either a modem or another network adapter in addition to the GC79. The modem or the additional network adapter is used to access the internet. The GC79 is used to share the connections with other clients.

Setting up Internet Connection Sharing (ICS) on the Host Computer

1. Connect the host computer to the internet.

2. Click the Start button.

3. Select Settings Control Panel.

4. Double-click Network and Dial-up Connections.

5. If the host computer is connected to the internet using a dial-up connection, double-click

Dial-up Connection Properties Sharing, and then ensure that both Enable Internet Connection Sharing for this connection and Enabled on-demand dialing are selected.

If the host computer is connected to the internet using a cable or DSL modem, double-click

Local Area Connection Properties Sharing, and then ensure that the Enable Internet Connection Sharing for this connection option is selected.

Note:

For Windows 2000, you must enable local network sharing and select the Local Area Connection relating to the Sony Ericsson 802.11b adaptor. You can check this by looking at the Device Name in the Network and Dial-Up Connections list. If your Sony Ericsson 802.11b adaptor is listed as Local Area Connection 3, then select Local Area Connection 3 in the 'For local Network' drop-down box. For Windows XP, follow the Bridging instructions below.

Advanced Wireless LAN Features 25

Bridge connections on Windows XP

The network bridge allows you to connect network segments by selecting the appropriate network connection and bridging them together. The network bridge manages your network segments, and creates a single IP subnet for the entire network. There is no configuration required, and you do not need to purchase additional hardware such as routers or bridges. IP addressing, address allocation, and name resolution is highly simplified in a single subnet IP network.

Only one bridge may exist on a Windows XP computer, but it can be used to bridge as many different network connections as the computer can physically accommodate.

Before you begin make sure you are logged on to the computer as an administrator.

1. Select Start Control Panel, and then double-click Network Connections.

2. Under LAN or High-Speed Internet select each of the private network connections that you want to be part of the bridge. You must select at least two eligible network connections in order for Bridge Connections to create a bridge.

3. Right click one of the highlighted private network connections, and select Bridge Connections. You can create only one network bridge on a computer, but the bridge can accommodate any number of network connections.

Caution!

Do not use this method to share a corporate network connection without first agreeing security procedures with the network administrator.

Note:

• Adapters that have Internet Connection Sharing (ICS) or Internet Connection Firewall (ICF) enabled cannot be part of the network bridge and will not appear on the Network Bridge checklist. Similarly, the Add to Bridge menu command is available only for adapters that you can add as connections to Network Bridge.

• Only Ethernet, IEEE-1394 adapters, or Ethernet compatible adapters such as wireless and home phoneline adapters (HPNA), can be part of the network bridge.

• Do not create a bridge between the public Internet connection and the private network connection, or add the public Internet connection to an existing network bridge, if you do not have ICF or Internet Connection Sharing (ICS) enabled. To do so will create an unprotected link between your network and the Internet, and your network will be vulnerable to intrusions.

• If you remove adapters from the network bridge, and less than two adapters remain, Network Bridge will not perform its intended function, but it will continue to use system resources.

• Network adapters that previously appeared under LAN or High-Speed Internet, appear under Network Bridge when they are added as connections. Network adapters that provide Internet connectivity, such as DSL and cable modems, cannot be bridged and will always appear under LAN or High-Speed Internet.

• Network bridges with wireless or IEEE-1394 connections support traffic using Internet Protocol version 4 (IPv4) only.

4. Internet Connection Sharing, Internet Connection Firewall, Discovery and Control, and Network Bridge are not available on Windows XP 64-Bit Edition.

Caution!

When sharing an internet connection, unwanted users within the reach of the wireless LAN may be able to use it too. It is recommended that you use of security features such as WEP network keys.
