SQI Vs. RxQUAL.

SQI: estimates the speech quality in cellualr networks as pereceived by human listener , the SQI includes :
1-BER
2-FER
3- HO data events
4- the distribution of BER over time
5- the speech codes been used

RxQual: is obtianed by transfering the BER into scale value ( 0-7 ).( only take the average BER

drawback :
1- doesn’t include the distribution of BER over time
2- NO mention Of FER
3- frames lost during HO
4- the choise of speech codec
