摘　　要：随着中兴、华为等中国通信设备商在海外捷报频传,"中国造"的通信品牌也在许多国家落地生根。在一些通信产业相对不发达的国家和地区,通常会遇到很多从无到有的全新的无线网络规划项目。对于GSM网络规划来讲,由于频率是有限资源,因此选择正确的频率规划方法就成了整个网络规划过程中至关重要的一环。本文根据业务类型对各种典型区域进行了分类,并给出了相应的站距规划和载波估算方法,然后分析了各种频率规划方案的优劣,给出选择建议,希望对于以后的无线网络规划工作有所帮助。The brand ＂Made in China＂ becomes more and more famous in foreign telecommunication fields when Chinese communication equipment manufacturer, such as ZTE and Huawei, take bigger and bigger steps in foreign Telecom markets. Engineers will face a whole new GSM network to plan in the developing countries or areas where the communication infrastructures are not advanced enough. So it is a very key work to make a good plan for the limited frequency resources owed by operators. In this article, we give a model to classify different areas due to the wireless environment and service types, with which we can predict the cell radius and TRX numbers needed. Finally we can select an appropriate frequency reuse pattern specially for the network to utilize the frequency with great flexibility and efficiency. May this article helps during the network planning in foreign areas.
