While I agree that Sprint will eventually have the most advanced network I don't think they will be first with LTE advance even if its easier for them to do it than Verizon or AT&T because tmobile can upgrade just as easy since they are using release 9 too. Sprint is far behind the other carriers in deploying LTE because they way they are doing it just takes more time so about time sprint is finished with its initial deployment of LTE the other carriers probably would have got the jump on LTE Advanced 6-8 months before hand
That's the fastest 4G LTE signal you've gotten in the Jax area? What was your signal strength? LTE is very signal strength dependent. LTE has been great pretty much everywhere in Jax for me and has gotten a lot better even within the last week. With a LTE signal of -110 to -114, I can easily pull-down 6-12mbps and 1.5-5mbps uplink. Once I get a signal better than -104, my speeds increase drastically, sometimes upwards of 25mbps downlink and 8-10mbps uplink. Just give Sprint some time to fill-in coverage holes and also get 800CDMA turned on. After that, you'll see better overall overage (especially for voice due to 800CDMA) and should see much faster LTE speeds due to getting better signal from having the towers all converted to NV. You'll also see your 3G EVDO speeds increase drastically once those towers are converted to NV. I easily get 1.5-2.5mbps downlink on EVDO now on the NV towers. They easily beat Verizon's speedtests on EVDO most of the time (I have devices on Verizon and AT&T). If you experience slow LTE speeds, it's most likely because the site your connected to is the only one in your area and is serving a large swath of people trying to connect to it (or you're not getting a good signal). Once more sites get converted to NV, the congested towers will be less congested. Once 800mhz LTE and 2.5/6ghz LTE gets lit-up in Jax, you'll really start to see Sprint shine (if you have a Tri-band LTE device). I'm already starting to Sprint's consistency rival Verizon and AT&T's in my area. Verizon might have faster burst speeds than Sprint's but Sprint's stays pretty consistent and Verizon's can really slow-down, almost as slow as 1mbps. AT&T is no different. Coming from somebody that has devices on all three carriers, there is no perfect carrier. Sprint is really starting to impress me and this time next year, Sprint will have the most advanced network in the industry and will probably be the first carrier to launch true 4G (LTE-Advanced).
