1、朗讯无线参数分类解释朗讯无线参数分类解释 网络中的无线参数是指与无线设备和无线资源有关的参数，这些参数对网络中小区的覆盖、业务分布、网络性能等具有至关重要的影响，因此合理优化无线参数是网络优化的重要组成部分。 针对电信总部提出的无线参数整改方案中提出的参数分类，朗讯公司提出相应参数在朗讯系统的定义和建议值情况。 1. 电信电信无线参数无线参数 parameter categoryparameter namedescription Pi l ot Gai n导频信道增益 Sync Gai n同步信道增益 Pagi ng Gai n寻呼信道增益 Pi l ot _St rengt h导频信道功率
