RSSI是否表征的是手机的“灵敏度”？

RSSI表示手机接收机当前接收到的外界信号的强度，与所处位置信号的强度有很大关系。不能绝对表征手机的接收性能。
但可以从对比测试大概看出手机的接收性能，比如同一地点和时间测试手机报告RSSI－100，而对比手机为－90，最少说明测试手机的接收能力有点问题。这种情况下如果传导测试灵敏度没有问题，一般是手机天线较差所致。

They suffer co-relationship.
First u should understand RSSI to indicate the sigal strength at the ANT feed as its abbreviation(Receiving Signal Strength Indication)
Second u should understand RSSI is not a directly measured value, however it is equal to Signal strength at the baseband envelop detector -base rx chain gain - variable rx chain gain + rx path loss.
Hope u understand my description.

Good!
Please describe the relationship between RSSI and Thoughput.
Thanks!

首先多谢楼上兄弟们的认真解答，心里热乎乎的

“比如同一地点和时间测试手机报告RSSI－100，而对比手机为－90”

就是说 ：
RSSI的值越大越好了吗？
这个值是怎么得到的呢？
校准数据中有一项就是RSSI的值，一直不知道这个校准值是怎么得到的

I am sorry but I can't catch your meaning of "thoughput"

以下内容含脚本代码[/td]Here the rx path loss[/COLOR] is actually a calibration parameter to indicate the insertion loss of rx chain which is stored in EEPROM说明：上面显示的是代码内容。您可以先检查过代码没问题，或修改之后再运行.

绝对不能这么说！RSSI饱含了有用信号和噪声，在信号很差的时候（接近手机灵敏度），噪声已经是RSSI中的主要成分，“比如同一地点和时间测试手机报告RSSI－100，而对比手机为－90”，这时候如果对手的辐射灵敏度好很多的话这种说法就不能成立！

I think you are talking about the data throughput. In fact the RSSI has no relationship with the throughput, the data throughput is mainly affeced by the sensitivity--e.g. the SNR at the BB.

知我者-biggestbug
1 It is throughput indeed.
2 RSSI has no relationship with throughput.
--RSSI is composed of signal and noise.
--When wifi module is 1m from AP, throughput is about 1.8Mbps and RSSI is the bigest.
--When wifi module is 10m from AP, throughput is about 1.8Mbps as well and RSSI is the
smallest
3 .signal quality(SNR) has relationship with throughput.
4.how to test noise level ?
-- signal is off,test noise?
-- noise analyzer

同意三楼cylbailey兄说的，RSSI就是这个含义

RSSI表征所处位置的信号强度，需与实际信号强度相符，所以需要校准
