Network Upgrade?

Sin City

There will be two different variants, one that supports HSPA+ networks, and another that supports HSPA+/EV-DO Rev. B and SV-DO. Does this mean that a CDMA carrier is willing to make the network infrastructure upgrades to CMDA 1x Advanced/SVDO?

With LTE/WiMax going forward, I wasn't sure that this would happen, but a dual mode handset with LTE/SVDO or WiMax/SVDO would win.

I never heard of the network standard SVDO.

A complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call. For example, users will be able to send emails or access the Web while on voice calls; phones with GPS can update maps or download real-time traffic information while on voice calls, etc. This device enhancement, which enables these concurrent voice and data services, is independent of the air link standard and infrastructure.

^If you want the full information. Phone Scoop provided this story months ago. CDMA 1X Advanced.

Yes. This article appeared August 18,2009 in EVDOinfo.com.

Interesting how history comes back around. Sprint fought for EV-DV before EV-DO. This would have given us the same benefits plus more. Nobody wanted it. Now here it comes in another form.

Exactly, Slammer. It upsets me every time that we were the only ones going hard for it, and but was ignored. Simultaneous Voice + Data was right in our grasps.

Actually, CDMA standards have included simultaneous voice + data.

Domestic carriers VZW & Sprint jumped straight from IS-95A (aka cdmaOne) to IS-2000 (aka cdma2000 1xRTT), but they skipped over an intermediate standard: IS-95B. While IS-95A permitted a mobile just one code channel, IS-95B allowed for aggregation of up to eight code channels, each of which could carry either 9.6 kbps or 14.4 kbps payload.

For example, an IS-95B mobile in voice traffic would use only one code channel. But a mobile in data traffic would use a maximum of eight code channels for a combined 76.8 kbps (8 x 9.6 kbps) or 115.2 kbps (8 x 14.4 kbps). And a mobile in simultaneous voice + data traffic would use one code channel for voice plus one to seven addit...

We know that CDMA was the newer and technological "better" advancement in wireless. During the time of CDMA vs GSM, I often wonder, that despite the deficiencies you mentioned, if it was still better to pursue EV-DV as temporary feed while progression pressed on. In my opinion, GSM's attraction, was/is the simultaneous voice+data. EV-DV may have given the edge to CDMA for a wider footprint which I personally would have love to seen. Thus, could've led to UMB as our 4G standard.

GSM's attraction in Europe or the U.S.?

Who is our? Sprint?

LTE makes sense for Verizon since Vodaphone is migrating to it as well.

They wanted it. They just didn't want to wait three additional years for it to be developed. When Verizon launched EV-DO in DC and San Diego, Sprint sneered and lauded EV-DV and how it would blow EV-DO out of the water so they were not going to bother with EV-DO. The problem was Verizon was gaining a huge market share in Data devices that Sprint had to shelve EV-DV and play catch up with the inferior technology, which just happened to be available in the real world at the time. Sprint did a great job catching up, too.

So voice and data simultaneously. Hell they need this now.
