Inherent advantages of LTE?

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.

Nope.

 

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."

      T-Mobile to acquire UScellular

      By iansltx · Posted

      A heavy n41 overlay as an acquisition condition would be a win for customers, and eventually a win for T-Mobile as that might be enough to preclude VZW/AT&T adding C-Band for FWA due to spreading the market too thinly (which means T-Mobile would just have local WISPs/wireline ISPs as competition). USCC spacing (which is likely for contiguous 700 MHz LTE coverage in rural areas) isn't going to be enough for contiguous n41 anyway, and I doubt they'll densify enough to get there.

      Boost Infinite with a rainbow SIM (you can get it SIM-only) is the cheapest way, at $25/mo, to my knowledge; the cheaper Boost Mobile plans don't run on Dish native. Check Phonescoop for n70 support on a given phone; the Moto G 5G from last year may be the cheapest unlocked phone with n70 though data speeds aren't as good as something with an X70 or better modem.

      Official Tmobile-Sprint merger discussion thread

      By iansltx · Posted

      Continuing the USCC discussion, if T-Mobile does a full equipment swap at all of USCC's sites, which they probably will for vendor consistency, and if they include 2.5 on all of those sites, which they probably will as they definitely have economies of scale on the base stations, that'll represent a massive capacity increase in those areas over what USCC had, and maybe a coverage increase since n71 will get deployed everywhere and B71 will get deployed any time T-Mobile has at least 25x25, and maybe where they have 20x20. Assuming this deal goes through (I'm betting it does), I figure I'll see contiguous coverage in the area of southern IL where I was attempting to roam on USCC the last time I was there, though it might be late next year before that switchover happens.

      Forgot to post this, but a few weeks ago I got to visit these small cells myself! They're spread around Grant park and the surrounding areas, but unfortunately none of the mmwave cells made it outside of the parks along the lake into the rest of downtown. I did spot some n41 small cells around downtown, but they seemed to be older deployments limited to 100mhz and performed poorly.

      What is the cheapest way to try Dish's wireless network?  Over the past year I've seen them add their equipment to just about every cell site here, I'm assuming just go through Boost's website?  What phones are Dish native?
