12.1 General Features of GSM Data
To put it simply GSM Data is the ability to send data or fax information over the GSM (Global
System for Mobile communication) network. Data over GSM offers new opportunities for both
GSM network operators and mobile workers alike. By using GSM to send and receive data or
faxes, mobile employees have access to a level of geographic mobility previously unobtainable.
The major benefit of using GSM data, is that you can use it from any location at any time. There
is no need to rely on being able to gain access to a Public Switching Telephone Network (PSTN)
line, or wasting time trying to find one. Using GSM provides a faster response time for mobile
employees. This is becoming an increasingly important factor in countries where the PSTN is
underdeveloped, but where GSM is widely available, such as Central and Eastern Europe. Using
GSM in a foreign country can also be a more cost-effective solution for mobile data than the fixed
network. For instance when staying in hotels, calls are charged at a premium rate making data
communication excessively expensive. By using GSM users can actually gain in cost advantage by
avoiding the premium charged by the hotel.
12.2 Key Benefits
•
GSM data can be used from any location at any time.
•
Ease of use for international travellers.
•
GSM data offers a use anytime, anywhere capability, unmatched by fixed telephone networks.
•
The cost of using GSM data is reducing over time
12.3 GSM & GSM Data – An introduction
GSM is the world’s most widely deployed digital wireless technology, with networks serving
more than 170 million subscribers world wide. There are currently more than 250 networks in
over 100 countries/areas around the world. Thanks to the world wide spread of GSM networks,
mobile users now have access to a level of geographic mobility previously unobtainable.
GSM offers advanced mobile data capabilities, previously unavailable on analogue cellular
networks. Users should select a GSM data solution vendor with developed expertise and
experience in GSM data. In that regard Ericsson is an excellent choice. In fact GSM is the ideal
communications technology for Ericsson Mobile Companion. Co-operation between the GSM
handset manufacturer and data solutions providers is the key to developing reliable, robust
products.
12.3.1 Lower power consumption
For Mobile Companion users, battery life is at a premium. Using a software based GSM solution
provides substantially improved battery performance for the Mobile Companion compared to
using a PC Card.
