With the launch of the second generation wireless network in 1991, the concept began to spread, which is to use our mobile not only to call each other, but to access and send multimedia content. Today, it is unimaginable that we could not use any web applications or social sites through our smart device anytime and everywhere. These demands are met by the fourth-generation LTE wireless network, which promises high speed and greater availability.

For this increased need for speed, it was necessary to change the architecture of LTE, compared to the previous generation networks. The packet-switched architecture strives to fit to the internet network as much as possible. It is important to apply new types of technology in the layers of LTE protocol to provide greater speed and stability than its predecessors. Due to the circumstances in the radio environment, it can still be said that it does not fit perfectly with TCP.

In this thesis after a review on related work, I briefly present how an LTE end-to-end network is built in a complex simulation environment, and its LTE module's processes and objects. I will perform general radio environment measurements on a heterogeneous network. I create different simulation scenarios to see how radio environment settings affect the throughput and the LTE network itself. Finally, I present the analysis of the LTE protocol stack layers.
