Abstract：Long term evolution-hotspot/indoor (LTE-Hi) was raised by the international standards organization the 3rd generation partnership project (3GPP) in release12 (R12). Overall, LTE-Hi is to satisfy the hotspot coverage requirement, which is the evolution of LTE technology and has the characteristics of lower cost and higher frequency in indoor scenario. LTE-Hi is mainly deployed to optimize LTE indoor scenario coverage in the 3.5GHz and higher bands. It is set to meet the future needs of the rapid development of mobile Internet data services to achieve a higher performance, lower cost.This thesis focus on properties of large scale fading model in classical wireless channel models. By choosing a typical indoor scene environment, the actual indoor wireless channels test data was measured. The data was performed by different fitting analysis and a better fitting curve was chosen as the results. Compared with relevant parameters of WINNER channel model, it is confirmed to be adaptable for the LTE-Hi system.
