GSM模块信号强度CSQ与RSSI的对应关系,新增android的ASU
那么好了,RSSI和CSQ之间的对应关系式什么呢?OK,就是:CSQ值=/2。其中0代表误码率,Ber。在通话的时候误码率不能太高,否则会听到嘶嘶沙沙的声音。现在android手机比较火,其中信号方面也有个描述,叫ASU,实际上就是RSSI. ASU or "Arbitrary Strength Unit" is an integer value proportional to the received signal strength measured by the mobile phone.In GSM networks, ASU is equal to the RSSI .dBm = 2*ASU - 113, ASU in the range of 0..31 and 99. In UMTS networks, ASU is equal the RSCP level 阅读全文
