如题。
Telecom operator A has got 94 channels in GSM900,and telecom operator B has got 29,Suppose both of then reuse frequency according to the pattern of [5*3(BCCH)+4*3(TCH)],without frequency hopping,and each cell has the same number of TRXs.Then,up to what TRX configuration can A & B respectively apply to a 3-sectored site?(Formula is needed in answer.)
谢谢高手帮忙解答,不胜感激!

看看了
扣除前后保护频点,A最大的配置可以做到S7/7/7,B可以做到S2/2/2.公式可以到教材里面找。
谷歌乱译:
电信运营商得到了一个94 GSM900的渠道,电信运营商乙得到了29,然后重复使用频率的假设都根据[5模式* 3不跳频,和(BCCH)+4 * 3(清桦)],每个细胞有相同数目的TRXs.Then,到什么的TRX配置可以适用于A和B分别为3扇区的网站?(一级方程式的答案需要。)
楼上的兄弟很有意思,支持一个!
挺搞的,看来英文水平还得提高。。。
