Brian X. Chen:
So why does Verizon’s Samsung Galaxy S III, a 4G LTE phone, juggle
calls and data? Samsung added an extra antenna so that it pulls
data from the 4G LTE network at the same time that it’s using
another antenna to do voice, said Anand Shimpi, editor in chief of
Then why didn’t Apple add another antenna? Its phone already has
two antennas in an effort to improve reception, and it would have
had to add a third antenna just for Verizon and Sprint phones to
give them simultaneous data and calls, Mr. Shimpi explained.
Leaving that third antenna out allows Apple to simplify the
process of manufacturing the iPhone for multiple carriers. Plus,
in the next two years, 4G LTE technology is supposed to evolve to
support voice calls, which would render another antenna
This is unfortunate, but it’s not going to keep me from switching to Verizon with my upgrade to the iPhone 5. I know some people use this feature, because I hear from them every time I write that it’s no big deal, but for me personally, I can’t remember ever wanting to use data while on a phone call. I just don’t make that many phone calls, for one thing. For another, the limitation only applies to cellular data — Wi-Fi works during phone calls on all iPhones.
(Also keep in mind that it’s not like the situation with the original EDGE iPhone, where, when you were using data, if you got a phone call it would go straight to voice mail. With Verizon and Sprint CDMA, an incoming phone call will interrupt your data stream and ring.)
