1. Mobile Phone Networking Systems 2G, 3G, 4G 2. The first worldwide mobile communication network that worked properly was the GSM networking system. An interesting fact is that the fins from Nokia had a lot to do with the development of these networking systems. 3. The GSM (or 2G) networking worked beautifully with voice calls and SMS system. It was powerful enough even for accessing simple sites on the internet or sending media files through the MMS services. But when people saw the opportunity for accessing the internet directly from the handheld device, the need for a stronger and faster data transfer was born. 4. GSM was powerful enough to provide a data transfer speed of only 13 Kilobytes per second. Some improvements were made to this type of networking. An intermediary 2.5G system that worked a little faster was also launched but the next big thing after 2G was the networking system that changed everything. The third generation of mobile communication technology was born and along with its appearance a new wave of 3G products like the 3G tablets, 3G netbooks, 3G smartphones, 3G USB adaptors for your mobile devices. Suddenly people had the impression that everything around them was going to be 3G compatible at some point in the future. 5. The truth is that 3G networking system did not only work as an advertising method because the services really provided higher data transfer speeds than anyone could have imagined at that time. The data transfer was working at speeds of 200 Kilobytes per second. This meant that the internet surfing was no longer a time consuming activity and video streaming was also possible on the mobile devices due to the downloading speed. Video calls also became popular along with the 3G networking because data transfer speed was also the factor that allowed this service to work properly. The operating systems also became more powerful and more complex to allow the complete exploitation of the connectivity. Online markets filled with thousands of applications became integrated in the menus on the new smartphones. 6. Like every domain the 3G networking system became fully exploited by the continuously improving technologies of mobile phone developers and a new data transfer speed standard was needed. The story of the next networking says that LTE or Long Term Evolution first released the 4G networking in Scandinavia and this happened in 2009. Although the technology existed ever since, the first reliable 4G compatible smartphones started appearing in 2012. Also the mobile communication carriers have only started providing 4G networking in large metropolitan areas at the end of 2011. 7. But during 2012 all the carriers took part in auctions and they have also faced a lot of negotiations for obtaining this package of services in order to provide them to their clients. By now, the 4G networking system has already spread all over the populated areas of the planet. This means that purchasing a 4G smartphone would now be an intelligent move to upgrade the previous devices if you are an enthusiast. 8. The 4G compatible smartphones manage to provide download speeds of almost 50 Megabytes per second (real download speed). This automatically means that using a smartphone capable of 4G networking, the owner will never have any trouble with loading any web page, no matter how large the page size will be. This connectivity can handle any upload/download in no time. Sharing HD files, accessing the internet, using the internet-powered services and any other internet related action will get done almost instantaneously. The 4G networking system is a truly revolutionary system and the benefits will become visible when the people will start to change the old handheld devices with the new 4G compatible ones. 9.
