Performance Evaluation of Lte and Wimax Network as per Use Cases

The novel wireless network architecture forces a demanding performance requirement on the radio resource to provide broadband internet access. The Communication industry has been preparing new standards to efficiently transport high speed broadband mobile access in a solitary air interface and network architecture at little cost to operators and end users. Two standards, IEEE 802.16 (WiMAX) and 4G(3GPP LTE) are most important group towards forming the next generation of mobile network standards. The WiMAX comes from IEEE family of protocols and expand the Wireless access from the LAN to MAN and WAN. The radio resource is divided as bursts in time and frequency domains and used by mobile stations (MS) in a best way. It utilizes a novel physical layer radio access technology called OFDMA for UL and DL. The initial iteration of WiMAX was supported with the TDMA TDD and FDD with line of sight (LOS) propagation across the 10 to 66 GHZ frequency range which was afterward increased to consist of operation in the 2 to 11 GHZ range with non line of sight (NLOS) capability via robust OFDMA PHY layer with subchannelization permitting dynamic allotment of time and frequency resources to several users. The LTE on the other hand develops from the 3G technology and describes the long term evolution of the 3G(3GPP UMTS/HSPA) cellular technology. The arrangements of these efforts are formally identified as the Evolved UMTS Terrestrial Radio Access Network (EUTRAN). 4G(LTE) describes a new physical layer radio access technology
