Re: voice quality
For E/// there is no counter to measure SQI in 3G just field measurement by PESQ/POLQA technique .

Re: voice quality
we use BLER to measure quality.
E/// formula=<pmFaultyTransportBlocksAcUl>/<pmTransportBlocksAcUl>*100)

Re: voice quality
Hi,
BLER rate shows faulty transport block ratio which basically related to transmission media and network. I afraid to say it does not show SPEECH QUALITY .If you have any practical case please share to be more clear to all.
Cheers

Re: voice quality
in our case E/// recomend this to use for voice quality. I guess a good ratio of successfully decoded transport block would always indicate good health of network.
