GSM is the second generation’s system for mobile telephony that is used today in parallel with the third generation (3G) and the newly built 4G. In 2011, GSM still had more users globally than the newer network for mobile traffic.
When GSM entered the market it was aimed to create a common mobile system for all European countries. The technique has since then been developed and is today based on technique from countries outside of Europe. There are four different variations of GSM, and which one is used depends on what region you’re in.
To many GSM may seem outdated because it doesn’t really catch up with the requirement of speed in todays apps, games, and videos. Despite of this, many countries in the world still use GSM as the main network for mobile communication.
- GSM is the second generation’s system for mobile communication.
- The system was commercialised in 1991 and the first network in Sweden was released in 1992.
- GSM is run in parallel with the 4G networks.
- There are four different GSM variations that are connected to different regions.
- Many still commonly use the GSM network for mobile communication.
- The requirement in today’s apps forces many users in western countries to choose 3G or 4G.
- The fundamentals for development of GSM were terminated in 1982.
Second generation’s mobile telephony system
GSM stands for Global System for Mobile communication and is the second in row of mobile telephony systems. The system was commercialised in 1991 and replaced the previous analogue system (NMT) in Nordic and European countries. GSM is still used today in roughly 100 countries including USA and Europe.
Thanks to GSM we started sending texts, something that most of us today take for granted. The system was developed to manage things such as WAP sites and MMS. It was also in connection with GSM that SIM cards were introduced, something that everyone uses in their mobile phones.
Europa använder sig av GSM-900 och GSM-1800. GSM is used in parallel with 3G and the newly built 4G network as complement. GSM exists in four different variations; GSM-1900, GSM-1800, GSM-900 and GSM-850. This is equivalent with the megahertz that is used to transfer data and numbers within the different frequency areas.
History of GSM
In 1982 a group called “Speciale mobile” was created by CEPT (European post and telecommunication authorities conference) with the mission to develop a technique for common mobile telephony system for all countries in Europe. Before the group was created, each country had developed their own systems, such as NMT in Scandinavia.
In 1991 services based on the GSM technique were commercialised. Sweden got its’ first GSM network in 1992. In the beginning GSM was a European standard but is now based on technique from countries outside of Europe which lead to today’s meaning of the acronym – global system for mobile communication.
Vissa hänvisar till GSM som 2G vilket är en efterkonstruktion baserat på tredje generationens namn – 3G. Under 2011 var det fortfarande fler som använde sig av GSM-nätet än de som använde sig av 3G-nätet. Allt eftersom appar, videos och liknande ställer högre krav på hastighet väljer fler att använda sig av de nya generationerna. Some see GSM as 2G which is an after construction based on the 3rd generation’s name – 3G. In 2011 there were still more using GSM than the newer 3G network. As apps, videos, etc, set new requirements of speed, more choose to use the new generation’s network.Glossary
