以广东省双频网为例，从如何减轻网络负荷、９００ＭＨｚ与１８００ＭＨｚ电磁波传播特性差异等方面探讨了双频网几种组网方式的优缺点，以及如何通过无线网络参数设置使话务流向ＧＳＭ１８００网，从而减轻ＧＳＭ９００网络负担。
Taking Guangdong Province’s dual-frequency network as an example, this paper discusses the advantages and disadvantages of several networking modes of dual-band network in terms of how to reduce the load on the network and the differences of electromagnetic wave propagation characteristics between 900MHz and 1800MHz, and how to set the traffic parameters to GSM1800 Network, thus relieving the GSM900 network burden.
