Abstract
This report presents a technical comparison and analysis of two developing pre-fourth generation (pre-4G) wireless communications systems: the long term evolution (LTE) and the worldwide interoperability for microwave access (WiMAX). This analysis is used to speculate on the possible evolutionary directions of 4G systems since the developing direction of the earlier generations of wireless communications systems has been historically strongly directed by their technological aspects. Special focus is laid on the air interface, especially the physical (PHY) layer and media access control (MAC) layers as defined by the open system interconnection (OSI) model. The higher layers are briefly discussed to provide a better understanding of the overall systems’ operation. The two pre-4G systems appear to use similar technologies that are optimized for each system. Because of the technological similarity, other factors such as business and marketing, may then be more important determinants of the pre-4G systems’ survival in the 4G systems evolution.
