I'm sure this has been mentioned deep in a thread somewhere, but I really don't know where to start so I thought I'd ask directly. First off, I haven't posted much but am a long-time lurker, I've been kind of a closet mobile network technology geek for quite a while. My question is this: does LTE have any inherent technological advantages that make it a better choice over WiMax? I know there are advantages now because it's become the de facto standard for 4G around the world, so there are many more products being developed, but, all other things being equal, was one better than the other, did one technology have better signal propagation than the other (if both at the same frequency?)?
How robust is the signal propagation of LTE at 1900mhz compared to that of CDMA at 1900mhz?
Also, how different will LTE-TDD be from WiMax at 2500mhz in terms of signal propagation and throughput/consistency of service/hand-offs/etc?
Once again, sorry if this has all been answered before, but I appreciate any insight all of you experts can provide!

LTE and CDMA on 1900Mhz should have the same propagation characteristics after network vision so if you get 3G & Voice you'll get LTE. LTE is better with lower signal from what I've seen you can get speeds of 20mbit/s at signal levels of -106dBm vs CDMA which drops down to 0.05mbit/s or less at -106 dBm. WiMax is a broadband technology, it's not meant for Voice, SMS, or MMS.

I thought Sprint got SMS/MMS working over WiMax

Wimax by itself only implements the bottom two layers of the 7-layer IP stack. The other 5 layers are supposed to be provided by IMS or GSM MAP or ... LTE is a more complete standard.

Clearwire would argue otherwise - they do voice over wimax now.

It's probably via a VOIP ATA integrated into their modems.
Edit: I forgot that I had a Clearwire VOIP ATA, I got it cheap from bestbuy and just set it up with voip.ms.

That is interesting, I previously remember my 3G icon always popping up when sending MMS/SMS and connected to WiMax, but it was been almost a year since that occurred.
Your 3G icon appeared because it was sending the MMS/SMS over the 3G signal, Not WiMax 4G signal.

That is my point, I thought I read about a year ago that Sprint/Clear has gotten SMS/mms working over Wimax. That was when I stopped seeing the 3g icon show when connected to Wimax

So hope that really comes true and lte everywhere 3g is

Its better than just Sprint's word. Sprint has spent millions on deployment plans and scheduling to bring LTE to every site with Network Vision upgrades. It is coming. Even to those remote and obscure sites out in the middle of a cornfield.
When people complain about Sprint's past deployments, it almost always because of assumptions about deployment. Not any official or inside deployment info. Everyone assumed Sprint and Clearwire were taking WiMax nationwide, but Sprint never said that. Because they never actually planned to do that.
However, Sprint says with LTE that they are going nationwide this time. And also we have the evidence if that and continually report on it. This is completely a different deployment. Not only unprecedented with Sprint. But actually, unprecedented with any carrier in America...ever.

I wish more people could understand this. I see so many comments on other blogs about how Sprint lied and never delivered on their promise to bring Wimax to whatever part of the country they happen to occupy. Yet, every promo or ad I ever saw regarding 4G from Sprint or any other carrier always said something to the effect of "4G speeds not guaranteed. 4G is not available everywhere."
