WebSep 20, 2024 · 目前主流的传播模型包括COST 231-Hata和3GPP TR 38.901中采用的ITU模型。COST 231-Hata是由欧洲研究委员会（陆地移动无线电发展）组织，根据Okumura-Hata模型扩展获得频率适用范围是2 GHz以下；3GPP采用的传播模型基于ITU传播模型扩展，频率适用范围是0.5 GHz~100 GHz。 Web华为初中级GSM培训题库附答案华为初中级GSM培训题库附答案单选题一1.传播模型分为统计型模型和决定型模型两种.下列哪个模型属于决定型模型:AACOST231WalfishIkegami模型;BOkumuraHata模型;CCOST231模 The Hata model is a radio propagation model for predicting the path loss of cellular transmissions in exterior environments, valid for microwave frequencies from 150 to 1500 MHz. It is an empirical formulation based on the data from the Okumura model, and is thus also commonly referred to as the Okumura–Hata model. The model incorporates the graphical information from Okumura model and develops it further to realize the effects of diffraction, reflection and scattering caused by cit… highly demanding task
