“…From the basic assumptions of the PHY layer, the basic OFDM parameters are calculated. Different OFDM parameters used are mentioned in [6] The WiMAX throughput given in [7] is used taking B is the bandwidth in use 3.5 MHz; sampling rate, n, taken is (8/7), 256; NFFT is the length of Fast Fourier Transformation, 192; Nused is the number of used carriers, code rate is the rate of channel coding and m is the modulation efficiency. Spectrum Efficiency= Effective throughput /Bandwidth…”

Abstract__In this paper, performance analysis of 802.16/WiMAX and 3G technologies is done considering both as a cellular mobile technology. The performance measures used for this analysis are path loss, signal to noise ratio, coverage range of a cell and capacity in terms of number of user supported. An example scenario is considered as a reference. Different parameters for this scenario are assumed and adopted from literature. This paper evaluates the potential of WiMAX as a cellular technology in comparison to existing cellular networks evolving from Analog (1G), Digital (2G), Digital network with high speed (2.5G) and transmission with high data rate (3G). At the end concluding that there is trade off between different network parameters.

“…Various broadband applications and services have been envisaged such as WLAN feeding, wireless DSL and fast Internet access. Cellular deployment scenarios with mobile subscriber stations (MS) enjoying WiMax services on their laptop [3] as well as residential stationary subscriber stations (SS) characterised by fixed installed customer premises equipment (CPE) are feasible. Interoperability is granted by certified standard compliant laptop/PC cards and terminals.…”

SUMMARYWiMax broadband MAN based on the IEEE 802.16d/e standard supports mobile as well as fixed wireless access services. The underlying subscriber data links are characterised by totally different radio conditions such as propagation, interference rejection capability, terminal antenna gain, pattern and height. This leads to a significant coverage mismatch, different user throughput, system capacity and spectrum efficiency. In this paper, the basic performance of mobile and fixed subscribers has been thoroughly analysed for homogeneous hexagonal 3.5 GHz cellular deployments of an OFDM-based WiMax system depending on cell size, frequency reuse and offered traffic load. Network level simulation results on user FTP-application throughput, channel load, modulation and coding scheme utilisation and packet call blocking have been presented for cell radius of 300, 1000 and 2000 m in tight 1 Â 1 and 1 Â 3 frequency reuse, respectively. The future performance enhancements from optional features as Block Turbo Coding, downlink Power Control, scheduling schemes, sub-channelling in scalable OFDMA and advanced antenna technology have been evaluated and simulation results provided.

In this paper, we propose some simple capacity estimations for WiMAX/ IEEE 802.16 system. The OFDM Physical layer of 802.16 is considered. We compare between the nowclassical data rates values based on OFDM considerations and data rates obtained in simulation taking into account inter-cell interference. Figures are given for various scenarios of frequency reuse (1x1 and 1x3) and services (real-time and FTP) allowing interesting observations about WiMAX radio efficiency. These results can be used as an order of magnitude of more realistic WiMAX performance results.
