Verizon iPhone 5 sarà in grado di accedere ai dati della cella durante una chiamata telefonica attiva?

Risposta breve, no. Risposta più lunga, puoi accedere ai dati Wifi durante una chiamata, ma non dati cellulari:

• Se ti trovi in un'area con copertura Wi-Fi, sarai in grado di parlare al telefono mentre utilizzi i dati.
• Se ti trovi in un'area con copertura solo LTE / 3G / CDMA, non sarai in grado di parlare al telefono mentre utilizzi i dati.

Una dichiarazione di Verizon è finita su The Verge :

The iPhone 5 was designed to allow customers to place a voice call on the Verizon Wireless network, while letting customers access the Internet over the WiFi.

E Anand fornisce dettagli tecnici :

So onto the iPhone – we know definitively that the iPhone 5 definitely doesn't support either SVDO or SVLTE. It's as simple as looking at the FCC documents and the appropriate sections in the allowed and tested simultaneous transmitters section for SAR (Specific Absorption Rate) testing. There, it's spelled out that only one air interface can be active at a time, and that only one antenna can be selected for transmit at a time. There's also an explicitly called out mention to VoLTE not being supported at present. I didn't replicate the entire table of simultaneous transmission combinations which need to be tested (it is a huge table) there are no entries with CDMA Voice being active at the same time as any data mode save WiFi. This has been confirmed as well by later statements by the carriers and Apple.

C'è qualche spiegazione in più sul perché questo è link (grazie a MacRumors ). Questa è stata una decisione hardware. L'aggiunta di supporto richiederebbe l'aggiunta di una terza antenna. La citazione pertinente

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 AnandTech.

Then why didn’t Apple add another antenna? It actually 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 its manufacturing process of the iPhone for multiple carriers. Plus, in the next two years the 4G LTE network is supposed to evolve to support voice calls, which would render another antenna unnecessary later.
