The results are conclusive – Apple has dramatically changed the signal strength to signal bar mapping in iOS 4.0.1 and the iOS 4.1 beta, making the dynamic range not only much broader, but the range values for each bar much wider. The range of signals that correspond to bars three and four are the same width, and bar two is only slightly less.
The cutoff value for two bars to one bar remains the same, but every other value has increased. The result is that the worst case drop of 24 dBm no longer makes all the signal bars disappear, but rather two.
Imaginea ce mai sus reprezinta cel mai bine aceasta modificare, dupa cum puteti observa Apple a modificat scalarea puterii semnalului pentru toate barele insa cea mai importanta modificare a fost facuta pentru barele 1 si 5, astfel ca atat prima cat si ultima bara vor afisa puterea semnalului la o scara mai larga decat in vechile versiuni ale iOS.
In definitiv acestea sunt doar modificari cosmetice deoarece adevaratele probleme ale iPhone 4 rezida in design-ul defectuos si nu in modul de calcul al puterii semnalului insa prin aceasta modificare Apple paseaza vina in curtea celor de la AT&T.
