Do any phones now have 1xA?

That's all good but what about building penetration? I've never had a WiMax phone but all forums are filled with complaints about signal strength. My point was that 2.5GHz will only be useful outside.

I didn't know. Maybe Sprint is going to have VoLTE soon? Maybe you or another mod was going to respond "I saw NV schedules with VoLTE mentioned"; I don't know. Anyway, even if I did know, there's plenty of people here who don't know this was even an issue.

Yes, but, Sprint's towers are at PCS spacing, right? So even if Sprint eventually puts 2.5GHz on all its 38k+ towers, it's gonna be an uneven experience.

If backhaul OPEX starts becoming an issue, Sprint has its own fiber backbone which it could, over time and starting at the sites most expensive to least fiber, connect to their own towers. Sprint would do the math: 1) cost of monthly fiber access to ATT, Verizon, Comcast, etc 2) loan to fund direct Sprintlink connection to sites + interest See where the breakeven point is - how many years before Sprintlink option is cheaper - and make a decision.

In the longterm, if Sprint keeps just 1 1xRTT carrier on PCS, then assuming the PCS licenses are multiplies of 5MHz FDD, will it add a 3MHz FDD LTE carrier or just fill the rest of the 2x5MHz block with more 1xRTTs?

As Sprint starts removing PCS EVDO carriers, will it still keep the same number of PCS 1xRTT carriers? Or will it rely on 800 1xRTT? A mod said that Sprint will not deploy LTE-800 on 15-20% of sites - urban ones where spacing is too tight - so the same logic would apply to deployment of 1xRTT on 800. Therefore, with the greatly reduced voice capacity on 800MHz compared to PCS (since Sprint will only have 1-2 1xRTT carriers on 800), it'd seem that until Sprint gets VoLTE, it has no choice but to keep the same number of PCS 1xRTT carriers that it has now until VoLTE arrives.

Do you mean that they will only put LTE-800 where they have the full 2x7 MHz? I thought they would deploy 2x3 where they can? How much spectrum does Southerlinc have in its iDen service area? http://www.southernlinc.com/coverage.aspx

Heard of Google? "s4gru clearwire"

You can't use EVDO speeds pre-NV as the baseline for "what's gonna happen if they decide to remove an EVDO carrier". From my reading of this forum, backhaul is the primary (?and only?) reason why EVDO speeds on Sprint are horrible. Once they add fiber backhaul to every site, then you can say "well given current EVDO speeds, if they removed an EVDO carrier . . ." But even if EVDO speeds continue to be "unusable" after NV, which they won't, if Sprint was able to actually survive having unusable 3G speeds and no LTE, I think they'll think it worth the sacrifice to maintain usable LTE speeds and unusable 3G.

Unless Sprint has spectrum sitting in a market unused, that would potentially harm EVDO/CDMA by taking away carrier from non-LTE users. They're gonna do it eventually even if it does harm nonLTE users. I expect they'll hold off until the average goes below the 6-8mbpa they're advertising.

Adding a second carrier wouldn't improve peak speeds but it would double average speeds.

So would spectrum per unit pop density be better?

Only Sensorly is available on iOS; any alternatives?

When will Sprint add a second 2x5 LTE carrier in PCS?

Is that cheaper for carriers? They're gonna look for cheapest. And while I understand the concept of small cells, how small are they going to be exactly?

Not per person http://www.fiercewireless.com/story/entner-lte-and-us-consumers-are-king/2012-10-19 It's not because the carriers aren't trying: the Supreme Court had to step in to make sure things wouldn't get bogged down even further. http://news.yahoo.com/high-court-uphold-fcc-power-cell-tower-disputes-144027871.html Local municipalities aren't making easy. Who should share with whom? Do you have tens of billions $$ to pay for people to move to different bands?

So wouldn't someone make money off hosting his network? If not Sprint then T-Mobile?

Yes, I agree but if the alternative is slower data speeds, won't phone consumers accept the costs? It's not as if we're talking about doubling the price of a phone. I'd definitely like to see that article. Aren't those solutions intended for alleviating congestion in relatively small locations like a mall, stadium, etc.? I'm thinking at the macro level at which point peppering cities with small cells might be more expensive than adding another spectrum band. Also, you're assuming antenna technology won't advance much. I know absolutely nothing about antennas. What about http://www.qualcomm.com/media/documents/files/qualcomm-rf360-front-end-solution-product-brief.pdf It does look like the solution's not optimal so maybe it's meant more as a "we're coming!": http://blogs.strategyanalytics.com/RFC/post/2013/03/19/Does-Qualcomms-RF360-Mean-The-Demise-of-GaAs.aspx

Maybe, or it may just end up underwater, like a lot of foreclosed homes during the housing crash. I have long been saying that we are unnecessarily flooding the market with so much new spectrum -- AWS-1, AWS-2, AWS-4, BRS/EBS, SMR, Upper/Lower 700 MHz, WCS, 600 MHz -- that the spectrum bubble could burst any day now. AJ How would it burst? Mobile usage-stuff is increasing, right? And America has ?second? highest data prices?

Ok fine. Since they're not gonna be bought by Dish ... resume thread.

What do you think is going to happen to the spectrum these two hold? Eventually, it's gonna be used by someone. If AT&T "built" a band from scratch using WCS, why wouldn't it also want to use DIsh's 2x20 in 2GHz?

Dish - they never asked Sprint to host their network. Lightsquared - they're trying to share some spectrum with (NOAA) http://news.cnet.com/8301-1035_3-57582692-94/finally-some-good-news-for-lightsquared-and-its-4g-hopes/

Eventually, Dish and Lightsquared will need a network to host their spectrum (assuming they don't sell it). As Sprint's network is currently planned out, will it be able to host Dish and/or Lightsquared spectrum? http://www.extremetech.com/mobile/135045-what-is-lte-advanced/4 What are the possible issues? Backhaul? Tower spacing? Competitive issues?
