| Summary: | This paper presents the results of investigation of fixed wireless access performance based on IEEE802.16 standard in wide campus environment. Measurements have been conducted at 5.8 GHz that includes various parameters in different outdoor environments to study the effect of vegetation, street and building. The primary goal of this work is to investigate the performance of received signal strength during daytime and night. Based on the measurement result, small signal deviation recorded for daytime and night. The channel capacity is found varied with environment conditions, wind speed, humidity and temperature. The extent of changes based on blockage is examined as well. The excess loss due to vegetation is ranging from 5.14 to 31.17 dB. Within the research framework, the empirical values obtained are to be scintillated with the statistical models. Henceforth, it is vital to discover the interrelation within the outstanding statistical distributions, such as log-normal, Gaussian, Rayleigh, Rician and Nakagami distributions. In such models, it is found that log-normal distribution best fit the path and excess loss models. |
