or to corporate networks.
Hardware Overview
The GC79 is a standard 32 bit type II PC card with a 15mm extension which contains the GSM

The amount of power drawn from the laptop battery is dependant upon a number of factors including
status, frequency band, distance to GSM base station and number of timeslots used. See Technical
Specifications on page 63 for a general guide to power consumption.
SIM Card
When you subscribe to a mobile network operator, you are issued with a SIM card (Subscriber
Identity Module card). The SIM contains your personal subscriber data. You need a SIM to use
your GC79.

• 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.
GSM Network and Subscription
The GSM network services you use in conjunction with your GC79 depends on the subscriptions
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, so check that the Internet or VPN service you require is enabled for 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 GC79
Manager, see GC79 Manager SMS Messages Screen on page 48, 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.
