本文讨论了目前国外提出的陆地移动通信系统中场强预测的十二种模型,分析比较了它们的特点及适用范围。并应用场强预测模型,预测了北京市公众移动通信网的场强。结果 Okumura 模型预测值最接近于实测值。可见,在规划城市移动通信系统场强预测中 Okumura 模型值得重视。
In this paper, twelve models of field strength prediction in the land mobile communication system proposed abroad are discussed, and their characteristics and applicable scope are analyzed and compared. And the field strength prediction model is applied to predict the field strength of the public mobile communication network in Beijing. Results The Okumura model predictions are closest to the observed values. It can be seen that the Okumura model deserves attention in the field strength prediction of planning urban mobile communication system.
