Among the 4G technologies they managed to enforce is the IEEE 802.16e mobile WiMAX technology. Mobile WiMAX promises to deliver high data rates in wide areas and at vehicle speeds up to 120 km / h. The performance of such a system is heavily influenced by the type of application you want to support, whether it is based on TCP (FTP, web browsing) or UDP (video streaming). The present work aims to analyze and compare the performance of a fully compatible mobile WiMAX system with a frequency of 2.3 GHz in a multiple vehicle fading channel (ITU M.1225 Veh.A). The results are generated on a link speed basis and are expressed in terms of the modulation and adaptive coding (AMC) switching points as well as the maximum achievable performance and operating range. Different packet error rate (PER) physical requirements, based on the quality of service (QoS) imposed, are considered.
