谁有OTA实验室测手机TRP  TRS的标准呀?谢谢!

狼烟

<P>老兄，要求没这么高吧，很难达到的。</P><P>OTA要求也就是TRP &gt;26dBm@GSM900,    &gt;25dBm@DCS1800</P>

bestdesign

对呀，来探讨一下，如果没有我们出一个。
测试环境，测试方法，和结果等，给出一个比较好的标准。

yanrutie

<P>看你的手机本身要求的数据是多少啊?比如说 在GSM 900M中 TRP 一般能比你要求的数据小个几个DB,比如说-2.45DB,那么效率有个57%,就说明你的天线和整机这方面配合的不错.</P>

bestdesign

一般，TRP>27dBm TIS>-102dBm--------GSM900
          TRP>25dBm TIS>-100dBm(-102)---------GSM1800

目前手机通用规格:
1.conducted output:33
GSM 2D EIRP≥31~32dB
               Sensitivity≥-100~-104(受手机环境的影响)
         3D          TRP>30
                         TIS>-100~-104(受手机环境的影响)
2.conducted output:30
DCS/PCS  2D EIRP≥28~29dB
                       Sensitivity≥-100~-103(受手机环境的影响)
                 3D           TRP>27
                                  TIS>-100~-103(受手机环境的影响)
3.conducted output:    LG:24
                                   通用规格:26
WCDMA           2D     EIRP≥20~22dB
                                 Sensitivity≥-100~-103(受手机环境影响)
                            3D  TRP>20                                 
                                  TIS>-100~-103(受手机环境影响)
如上如有不足之处请指教[br]<p align=right><font color=red>+3 RD币</font></p>

RF110

2D EIRP应该是某个面上的某个角度的最大值吧,以你提供的数据看,天线在这个方向点上效率达到100%了

CTIA只是提供了测试方法，并没有具体的要求极限值。
那都是每一个Operator具体要求得。

xxgoodbaby

真恶心，这个资料随处都可以找到；还要收10RD币，黑心。

不就是CTIA的测试标准吗?需要那么多RD吗?晕~~~~~~~~,都忙着赚钱了!!!!!!!
