Physical layer test trials and analysis of call drops and real time throughput versus channel capacity of the long term evolution (4G) technology

LTE is designed with a goal of evolving the radio access technology under the assumption that all services would be packet-switched, rather than following the circuit-switched model of earlier systems. Moreover, LTE is accompanied by an evolution of the non-radio aspects of the complete system, under the term System Architecture Evolution (SAE) which includes the Evolved Packet Core (EPC) network. Together, LTE and SAE comprise the Evolved Packed System (EPS), where both the core network and the radio access networks are fully packet-switched. This thesis mainly emphasizes on Physical layer and a proof for the physical layer message sequence.;The main purpose of this master thesis is to study, analyze and implement a proof of Physical layer process in control plane of LTE system. The focus is on physical layer between the UE and eNB. Test trials were performed and screenshots for the analysis of call drops were taken and included. Results show the achievable Downlink and Uplink throughput in multi user and single user environment compared with the channel capacity of 10MHz channel. The thesis is mainly based on 3GPP LTE specifications and discussions.;The methodology undertaken was divided into five parts. First, the studies part which was mainly based on 3GPP LTE specifications and real time work. Second, the testing part which was performed in a real scenario of LTE system deployed specifically for this test. Third, the analysis part, where the call setup procedure and physical layer message proof is implemented. Also, the call drops incurred during the test and its valid reason is analyzed. Fourth, the results part whereby the Average and Peak Achievable Downlink and Uplink Throughput for LTE is shown meeting the 4G requirements. Last part shows the conclusion that all the specifications mentioned by 3GPP is followed and proven that LTE is one of the best wireless communication technology of recent time.
