TyrellCorpse Posted July 21, 2013 Share Posted July 21, 2013 What is the status of Sprint going to LTE-A and when. It sounds like ATT and VZW will start trials later this year but may be a major effort to deploy nationwide. Word is VZW needs to do major infrastructure upgrades, ATT too? Sprint supposedly only needs to do a software upgrade on existing LTE sites. Is this true and can Sprint LTE phones also be upgraded to LTE-A via software or just the cellsites? Is LTE-A backwards compatible to (rel8/9) LTE within same spectrum or do they have to dedicate different versions in different spectrum? One big advantage of LTE-A from what I understand is that it double the capacity within the same spectrum, going from about 15bps/hz to 30bps/hz, allows Carrier Aggregation and better suited for VoLTE.

lilotimz Posted July 21, 2013 Share Posted July 21, 2013 Yep and Verizon has begun. They're swapping out old antennas now and adding RRUs. Quote Link to comment Share on other sites More sharing options...
Sprke Posted July 21, 2013 Share Posted July 21, 2013 Yep and Verizon has begun. They're swapping out old antennas now and adding RRUs. So your saying they have to swap out antennas they just put up for 700 LTE? They've only been up for a couple years, why wouldn't they have put up more future proof gear?

TyrellCorpse Posted July 21, 2013 Author Share Posted July 21, 2013 http://www.geek.com/mobile/what-it-would-take-for-verizon-to-go-pure-lte-1542139/ Details surrounding the actual (VZW) LTE rollout are sparse still, but based on what we know about Verizon’s network right now it is unlikely that the transition will be a simple, network-wide switch to this new platform. When considering Verizon’s current resources, and understanding that each and every LTE tower would need to be updated physically and individually, bringing their entire LTE network up to VoLTE before 2015 is likely cost prohibitive. What about Sprint and ATT? Quote Link to comment Share on other sites More sharing options...

CaryTheLabelGuy Posted July 22, 2013 Share Posted July 22, 2013 Can some of or all or the existing LTE capable Sprint phones use LTE-A or does this also require hardware change? If this does require new hardware, do you guys think the new Tri-band LTE phones will be LTE-A capable? I know a lot of this is total speculation, but hopefully maybe somebody has some inside info on the matter. Sent from my Sprint iPhone 5, not the old one (using Tapatalk 2).

This is a yea and no answer. It all depends how the lte-a is set up and use. If faster speeds to phone, then yes you will need a different phone. However lte-a will bring along carrier aggregation. This will be a benefit to all phones. Quote Link to comment Share on other sites More sharing options...
TyrellCorpse Posted July 22, 2013 Author Share Posted July 22, 2013 However lte-a will bring along carrier aggregation. This will be a benefit to all phones. And it doubles the capacity within same amount of spectrum before even using CA. LTE-A bumps efficiency from about 15bps/hz to about 30bps/hz (max).

Many insist LTE-A is just a software upgrade for Sprint but is not clear if on the cellsite end only or phones as well. Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted July 22, 2013 Share Posted July 22, 2013 Current Sprint devices do not have LTE Advanced capable basebands. But LTE Advanced is backward compatible with LTE devices -- just as CDMA2000 is backward compatible with cdmaOne devices. AJ Quote Link to comment Share on other sites More sharing options...

WiWavelength Posted July 22, 2013 Share Posted July 22, 2013 Do you know if the tri-band devices coming out this year will be able to upgrade to LTE-A? Basically, all Sprint LTE devices to this point have utilized one of two Qualcomm basebands: MSM8960 (chipset with integrated baseband) or MDM9615. Neither supports LTE Advanced. The capability is either built in to the baseband or not -- there is no "software upgrade." Current tri band LTE devices are likely using the MDM9615, so they will not be LTE Advanced capable. Future tri band devices will likely switch to the Snapdragon 800 MSM8974 (chipset with integrated baseband) or MDM9625, both of which support LTE Advanced. But you are barking up the wrong tree if you are looking for future proofing. Whether it be LTE 800, TD-LTE 2600, LTE Advanced, or something else, your device will always be lacking something only a few months after its release.

milan03 Posted July 23, 2013 Share Posted July 23, 2013 LTE-A bumps efficiency from about 15bps/hz to about 30bps/hz (max). In order to achieve that kind of efficiency, you'd need to implement higher order MIMO. LTE-A isn't a magic switch that will increase that spectral efficiency by default.

lilotimz Posted July 23, 2013 Share Posted July 23, 2013 Clearwire / Sprint is jumping straight to carrier aggregated 20+20mhz pipes which is one of the key elements of LTE-Advance. So in a way, yes. But the issue is there's no device out there that can do carrier aggregation, yet. Not until the S800 series of chipsets come online at least...
