I would like to ask finally who has ANY proven trace of any SIGNIFICANT measurement difference between "originally calibrated" and "GDFS-overwritten" K800 mobile ???
1) Did anyone compare in real both mobiles at the same time or it is just theoretical fact of error in measurement?
2) OK, if there is an error ... is it 0,1dB ? 0,2dB? maybe half or even 1dB ?
From my point of view (real life) this 1dB or 2dB doesn't make any big difference.. because I meet the same discrepancy already in picking different drive test car.. for example small KIA with normal window glass or big Nissan with thermo glass ... difference of 1dB already in "car penetration loss" is obvious ..
Same story with the rest of my test mobiles.. Nokia N80 (NTM) shows constantly 2-3 dB better signal level (RSCP) than both Samsungs (Z500 and Z560) .. should I conclude my Samsungs aren't RF calibrated ??? or they are just worst peace of equipment than Nokia ??
So.. what is real difference in dBs between "GDFS-overwritten" k800 and factory calibrated TEMS k800?
Anyone ??
regards as always..
