Remember the 'grip of death' fiasco that hit the AT&T iPhone models? Of course you do. Well as Verizon primes itself for the release of its own iPhone model experts say steps have been taken to ensure the story isn't repeated.
Spencer Webb, an antenna engineer with nearly a dozen patents to his credit has checked out a few images of the slots in the external stainless steel frame (which houses the phone’s antennas) on the redesigned model and he suspects that in order to solve the problem Apple have opted for a dual antenna.
The problem seen in summer was apparently caused by placing part of one’s hand over a slot which degraded performance by bridging the separate antennas, changing the length of the cellular antenna and thus its ability to receive and transmit. (I don't have a clue either.)
It is thought that in order to have an antenna shift around the SIM card slot seen in AT&T models was removed from the Verizon version of the handset.
“As soon as you get rid of the SIM card, you get a whole lot of real estate inside the phone,” said Webb. “Enough to shove a Wi-Fi antenna behind the glass back.”
By moving the Wi-Fi, Bluetooth and GPS antenna inside the iPhone, it freed space for Apple to craft two cellular antennas within the steel frame, Webb added.
Problem solved. (hopefully)
