Today more and more people use mobile internet. The spreading of smartphones, mobile applications that have to be online and high definition videos increase the used network capacity and bandwidth. Third generation networks are available in almost every city. Increasing usage effects that mobile cells can’t serve fully the increased needs in peak time, so becomes more and more necessary to introduce new technologies that provide more capacity and bandwidth. Before the real fourth generation networks, LTE (Long Term Evolution) offers solution for the capacity problems. In Hungary LTE service start-up was at 2012th January 1. First part of my thesis presents shortly the evolution of telecommunication systems and describes the attributes of the current third generation networks and LTE.
In the second part of this job I compare the performance of 3G and LTE networks. I show the differences from realistic environment measurements that users can notice. During the measurements I tried to construct generally models that can come up when people use mobile internet, e.g. indoor coverage of high buildings, effects of the vegetation in parks.
