Verizon Wireless customers can't talk on their smartphones while surfing the
Web, posting pictures to Facebook, or poring over Google Maps. In fact, Verizon's
Droid users can't even get apps that need an Internet connection to work
properly if a caller is on the line. In this data-driven world, what's a multi-tasker
to do?
The limitations of Verizon's network are a function of its reliance upon code
division multiple access (CDMA) technology. Specifically, Verizon Wireless uses
"evolution, data only" (EVDO), a third-generation (3G) protocol that drops the
data when a call comes through. By contrast, AT&T uses a global systems for
mobile communications (GSM) protocol that can handle both voice and data.
If the choice between Verizon and AT&T sounds simple, think again. By next
summer, the Verizon iPhone is expected to incorporate a new chipset and CDMA
update that can handle both voice and data traffic at the same time. Industry
analysts believe that this new architecture may enable Verizon to drop fewer calls, too.
Will you wait until summer to buy a new smartphone?
