RoccoM Posted March 10, 2012 Share Posted March 10, 2012 (edited) or are we just going to see Rev A/SVDO with massively improved backhaul/capacity upgrades? I've always been confused on that point, thanks. Edited March 10, 2012 by RoccoM Quote Link to comment Share on other sites More sharing options...
Denny Posted March 10, 2012 Share Posted March 10, 2012 A Sprint representative replied back on September 29, 2011 We are committed to continue our support for EVDO Rev A. We checked out EVDO RevB some time ago, and decided to move directly to 4G technologies. We will not be rolling out RevB http://community.sprint.com/baw/community/buzzaboutwireless/network-and-coverage/blog/2011/09/15/what-is-sprint-network-vision#comment-29424 Denny 3 Quote Link to comment Share on other sites More sharing options...
S4GRU Posted March 10, 2012 Share Posted March 10, 2012 Thanks Denny. This is right on. No Revision B. But Sprint is deploying DO Advanced with its Revision A in Network Vision. It gives a lot of the benefits of Revision B, except carrier aggregation. Sprint 3G will benefit greatly from DO Advanced. - Robert Posted via Forum Runner 2 Quote Link to comment Share on other sites More sharing options...
legion125 Posted March 10, 2012 Share Posted March 10, 2012 Good to know. I always thought each step had to be added as a layer to the other or concurrently. Didn't know you could add DO Advance to Rev A. Quote Link to comment Share on other sites More sharing options...

Denny Posted March 10, 2012 Share Posted March 10, 2012 EVDO Advanced is a software upgrade that increases efficiency of the cellular network. The easiest read I have found is http://www.cdg.org/resources/files/fact_sheets/CDG_DO_Advanced_FEB_2012.pdf Denny 3 Quote Link to comment Share on other sites More sharing options...

ImmerStark Posted January 18, 2014 Share Posted January 18, 2014 It seems kind of silly that Sprint is replacing all the ev-do hardware and not going with Rev. b. Quote Link to comment Share on other sites More sharing options...
utiz4321 Posted January 18, 2014 Share Posted January 18, 2014 It seems kind of silly that Sprint is replacing all the ev-do hardware and not going with Rev. b. There is no ecosystem for rev B. All going to rev B will do for sprint will make the cost of handsets go up for them. The faster evdo data will not be a big gain as their entire network will have lte. 1 Quote Link to comment Share on other sites More sharing options...

ImmerStark Posted January 19, 2014 Share Posted January 19, 2014 Last time I checked all modern Qualcomm basebands are rev b capable, sprint is still selling non LTE devices, and evdo has better coverage than LTE. I think they thought LTE was going to be the end all be all of mobile data but it hasn't been the panacea they had hoped for.

WiWavelength Posted January 19, 2014 Share Posted January 19, 2014 Last time I checked all modern Qualcomm basebands are rev b capable... The installed base is not what you think. Almost no OEMs enable the necessary hardware and software for Rev B. It very rarely shows up in FCC OET authorizations. AJ 1 Quote Link to comment Share on other sites More sharing options...

The Dave Posted January 19, 2014 Share Posted January 19, 2014 There would be little point in wasting the time, money and spectrum to support Rev B and aggregate data to increase 3G speeds to just be a fraction of the speed of LTE. By the time any implementation could be widespread to be useful, LTE will be as plain vanilla as Rev A is to us now. Quote Link to comment Share on other sites More sharing options...

EmeraldReporter Posted January 19, 2014 Share Posted January 19, 2014 (edited) So DO Advanced is a part of Network Vision 1.0, (2.0?) right? Or is this wishful thinking since EV-DO Rev. B, and EV-DV are now out of the question? Is Verizon going to implement DO Advanced within their network?

EmeraldReporter Posted January 19, 2014 Share Posted January 19, 2014 (edited) No on Verizon adding DO Advanced to their 3g network. Sent from my MB855 using Tapatalk So will this allow Sprint to "compress" the amount of spectrum they use for EV-DO carriers, from three to 2, or all the way down to 1? Can you answer this?: What is the spectrum use ratio in efficiency between EV-DO Rev A, EVDO REV. A Adv., EVDO Rev. B, and LTE release 9?

S4GRU Posted January 19, 2014 Share Posted January 19, 2014 Sprint cannot add EVDO carriers for EVDO-B to run at full speed in the markets where they will be counting on the spectrum for LTE. They need that for an additional Band 25 LTE carrier. Since Sprint has such a high LTE device adoption rate, they really need to be focusing on LTE performance above all.

Sprint needs to keep all of their existing EVDO carriers in tact. All DO-Advanced does is make EVDO more efficient in terms of load balancing, single multi link, etc. There is no such thing as EVDO Rev A. Advanced.

Robert via Samsung Note 8.0 using Tapatalk Pro I'm more than a little miffed that Sprint sold at&t 10MHz of their PCS spectrum in my market back in 2009. We really could use another LTE carrier, it's been 6 months since LTE launched here and there are already spots where it is overloaded to the point of being useless.

Same boat here, they sold 5x5 to AT&T a few years ago too. Another LTE carrier could be used all over town. LTE just doesn't work anymore in most places. In pains me to say it but the network feels like it did before NV started. 1 Quote Link to comment Share on other sites More sharing options...
ImmerStark Posted January 21, 2014 Share Posted January 21, 2014 Our only hope of salvation is a good dense band 41 deployment. Even though my market is in the top 50 we never got WIMAX and I have a feeling I won't be seeing any band 41 LTE until 2015 and still probably just on our four protection sites. I'm betting it will be 2016 before there is a real deployment. Quote Link to comment Share on other sites More sharing options...

How do you define useless? what sort of speed are you seeing? because even with LTE as long as its faster than 2Mbps down i would take it anyways because thats still enough to stream music and video. What is the 3G speed like? Quote Link to comment Share on other sites More sharing options...
