The reasons for the called drops become shadier every minute. First, analysts suspected hardware faults. then, Chuq van Rospach stepped up with his theory of software problems. Now, Daniel Eran Dilger’s Roughly Drafted news service has yet another theory:
According to him, the reason for the issues is a weird interaction between the iPhone’s software and the base tower’s transmitter. Base stations do not have unlimited transmission power available, and thus must kick out clients as power runs low.
As iPhone’s request way too much power, AT&T’s base stations run out of power in areas where many Appleheads are located. Daniel uses this to explain the weird issues why areas like San Francisco had worse issues than other countries, and why AT&T has sent out SMS asking users to upgrade ASAP…
