本研究的目的是分析2.4GHz频率下的信号传播。此频率预留给Wifi / HyperLAN常用的ISM频段。涉及三种类型的环境场景：室内传播、室外传播和建筑物间传播。传播测量是在吉隆坡大学英国马来西亚研究所进行的。利用对数距离模型对测得的路径损耗信号进行了分析和比较。仿真结果与预期一致。仿真结果与实测数据相吻合，并具有一定的相关性。此外，本研究还从对数距离模型本身得到了适用于2.4GHz频率的新的路径损耗系数因子n。n值对于路径损耗预测起着重要的作用，因为它代表了信号所经过的不同障碍物。
The purpose of this research is to analyze the signal propagation at 2.4GHz frequency. This frequency is reserve for ISM band which is commonly used in Wifi / HyperLAN. Three types of environment scenarios are involved which are indoor propagation, outdoor propagation and propagation between buildings. The propagation measurement is taken at University Kuala Lumpur, British Malaysian Institute. The measured path loss signal is analyzed and compared using the Log Distance Model. The simulation results obtain from this study were as expected. The results obtained from simulation and measured data are accordingly same and related to each other. Moreover, the new path loss coefficient factor, n yields from the Log Distance Model itself which applicable for frequency at 2.4GHz is obtained in this research. The n value plays an important role for path loss prediction since it represents the different obstruction which the signals pass through.
