Nowadays the usage of mobile phones and the cellular network is becoming more and more common. While in the 90s and even in the early 2000s we only made a couple of phone calls and sent a few text messages on our mobile phones, now there is hardly any task that we are unable to perform on them. With the introduction of smartphones, all the applications that previously required a personal computer have become accessible anywhere at any time.

With the exponential growth in the number of mobile devices and the appearance of applications that generate an enormous amount of traffic, it has become necessary to increase the capacity of the radio access network as well. While the first packet switched data services only offered a couple kbit/s of bandwidth, now, only about 10 years later we have technologies that allow us more than 100 Mbit/s bandwidth. However, the progress doesn’t stop, the users have continuously growing capacity needs, therefore we must totally exploit the current technologies as well as searching for new and new areas to improve.

In my thesis I demonstrate the ways of radio access in the mobile network services currently available to the public in Hungary, paying extra attention to the growth of bandwidth capacity, analysing the technological solutions that made the evolution possible. After that I demonstrate the possible directions for further progress. Finally, I examine one of these potential paths for growth, create a model that describes is, implement it in a simulation environment, give an approximation for the resulting capacity flare and compare and evaluate the approximated and simulated results.
