Hey
iam wondering about RSSI (Return Strenght Signal Indicator) values. Its easy to read in Wintesla but what do the values mean & how can they help us? If anybody knows what are the range of values & what they mean.

ie -120 = faulty ???
-110 = Normal range
- 80 = VCO problem????

If anybody knows what fault causes incorrect values, could they please respond.

Thanks!!

DREAMGSM

use search old post in forum will help

and use oscilloscope to measure Hager to COBBA ( make sure which part is problem ) RX IP/QP signal , then you will see is it correct and balance !

yes BUT how do you re-write correct values to ME?

willy · 11-11-2002, 18:28

Hakika,

"write" correct values to ME !

Wintesla has RX caibrition , it need signal generator to provide a standard signal and level to phone ( like for GSM at CH 60 947.06771Mhz and level -55 and -80 dbm) , and let ME to "learn" what is correct level !

if phone function correctly, then that two different level will be A/D convert and save to eeprom !
