Performance Evaluation of IEEE 802.11g System under Different Channels Condition

This paper studies one of the most widely deployed Wireless Local Area Networks (WLANs) based on IEEE 802.11g standard. The IEEE presented the IEEE 802.11g standard for providing higher data rates up to 54 Mbps at the 2.4 GHz frequency band. However, the simulation results obtained with varying channel conditions represented by typical models are indicative of the performance of OFDM in different environments. The channel adaptation process essentially captures the propagation characteristics of a typical WLANenabled office ranging from a small room to a large open space. MATLAB has been chosen as the modeling tool because of its flexibility and mathematical simulation capabilities. The results show that certain channels are better than others and will help in evolving a signal power benchmark for effective communication
