Acknowledging that an FDD allocation for the upcoming 600 MHz auction has considerably more support than the TDD approach it has been pushing, Sprint said it now supports the idea of an FDD band plan, provided it is structured to maximize "auctionable bi-directional paired spectrum."

You mean like how they made AT&T happy with the Tmo purchase?     Robert

I don't know how unpopular that position is, and I agree with most of it.   If we're going to kick TV off spectrum again, I'd rather use it for something actually productive (such as making it unlic

It's sad the other carriers are so dead set on FDD, it is not the most efficient mode for LTE. It if also possible that there will be isolated 6MHZ channels that become available with no possible paired channel for a discrete uplink.

So from this article, it seems Sprint is set on FDD on the 600 Mhz auction? 

Sprint originally wanted TDD for 600 MHz but it's abandoned that plan because no one else wanted it. Also, I believe that TDD isn't well suited for these lower frequencies.

Okay, but FDD would be more ideal than? If sprint were to snag some 600 Mhz for FDD, this would make Sprint a Quad band LTE network?

Ehh FDD VS. TDD is kind of a hot topic, but both have their strength and weaknesses. Also, Yes is if Sprint got some 600 MHz it would be quad band.

I'd rather have 1xA carriers on 600 unless Sprint switches to VoLTE

600 may propagate too well for something that works so well with a weak signal like CDMA. It almost couldn't be used in an urban environment at all. You will have lots of bars in your signal strength indicator, but the quality of the signal would get pretty crappy. It's almost too good on SMR.

 

LTE on 600, especially given the fragile LTE airlink, could prove to be pretty good. Especially in rural areas allowing one boomer tower to cover a lot of distance.

Hmm Robert that's interesting. I've never heard that before (well I knew CDMA worked well on a  weak signal and LTE was pretty fragile).

 

What about capacity on 600 LTE? Good enough to fill in holes left by 800/1900/2500 I assume, but would only be used as a last ditch effort with the pretty low capacity, correct? Would that give the LTE coverage needed to get a leg up on VoLTE rollout?

Quadband phone???? ;)

 

Sent from my Nexus 5

 

There are already quad band lte phones on the market for other carriers so this is not unrealistic :) Over the coming years I fully expect to see hexaband LTE phones, at least if we see sprint and tmo hop into the sack with each other. The PA's exist, there are issues right now with fitting too many antennas in phones but this will evolve. 

 

It would be interesting to see what SprinTmo and to an extent AT&T did with regard to band access. Do you allow pretty much all phones on all bands or restrict access to some bands to premium phones? Sprint have said triband for all, but if they suddenly find themselves with 6 or 7  bands (600, 700 , 800 , 1700\2100, 1900 , 2500), would this affect the cost of handsets enough to make it worthwhile to not include access to some of the bands? i.e. if you have access to 1900 LTE does it really matter to allow access to the (potential) 1700\2100 LTE. These are just idle musing rather than any suggestion Sprint may attempt to screw people or anything similar and it will be a little less complex should Sprint not buy tmo.

VoLTE on 600 will provide decent coverage. It will be closer to closing the VoLTE coverage gap. Put it on 450 like Africa, and maybe close it all together.

Question.... With 800 already in place wouldn't 600 just be redundant?

If no additional low frequency capacity was ever needed, then yes. But ideally, Sprint should have at least a 10MHz wide low frequency carrier. That can never happen on 800.

 

Sprint needs to do the best it can to be competitive. It will survive without any 600. But if and when it comes to market, it should try to get it.

I know you may just be throwing that frequency out there but isn't 450Mhz reserved for public safety in the US?  I know in my area, public safety uses 453 and 458 Mhz.

It was used for theoretical discussion of how to close the VoLTE coverage gap. It certainly is not possible in the U.S. But I bless the rains down in Africa.

I thought you were speaking in theory but just making sure. Thanks.

      Kind of amazing that T-Mobile is still holding onto that speed title despite Verizon all but killing off lowband 5G on their network. While Verizon is mostly being evaluated on mmWave and C-band performance, T-Mobile and AT&T's average 5G speeds include their massive lowband 5G networks that are significantly slower.

      Yup. Very true. We were originally on an Everything Data 1500 Plan, which got Unlimited Minutes thanks to Marcelo's "Loyalty Benefits" offer. We then switched to Unlimited Freedom (with the Free HD add-on that Sprint originally wanted $20/month per line for.... remember that?) because the pricing was better with "iPhone for Life", vs. the "Loyalty Credit" for staying on a Legacy Plan. After that, I ran the numbers and switched us over to Sprint MAX, especially for the international travel benefits. There's absolutely no reason for us to switch to Go5G Plus or Go5G Next if we're going to do BYOD by purchasing from Apple/Samsung/Google directly as we've been doing. These new plans aren't priced for current customers to switch to. They're priced for new customers, where they throw in a free line, etc. It's gone from "Uncarrier" to "Carrier". What a shame.

      Strange business model that they keep around all these pricing plans. 1000s of plans per carrier is reportedly not uncommon.  Training customer support must be a nightmare. Even MVNOs have legacy plans. A downside of their contract mentality I guess. Best to change contracts during a recession. But then all carriers try to squeeze out legacy plan benefits as they grow old.

      Everything "Uncarrier" is becoming "Carrier" again. Because of the Credit Limit that T-Mobile put on our account for no reason at all (and wouldn't change/update the last time I checked all the way up to the CEO), I don't plan on buying/upgrading our iPhones through T-Mobile. I'm going through Apple directly. Looks like I'll be going through Google and Samsung directly for our other lines for upgrades. Also, we're staying on Sprint Max given the ridiculous pricing for Go5G Plus. On Sprint Max, we currently pay for our Plan: $260 for 7 Voice Lines $25 for two Wearable Lines. (One is $10/Month. The other is $15/Month because the AutoPay discount only applies up to 8 lines.) Total: $285/Month vs. Go5G Plus (Per the Broadband Facts "nutrition label" on the T-Mobile Website): https://www.t-mobile.com/commerce/cell-phone-plans $360 - ($5 AutoPay Discount x 7 Voice Lines) = $325 The Watch Plans show as either $12/Month or $15/Month: https://www.t-mobile.com/cell-phone-plans/affordable-data-plans/smartwatches So this is about the same for the wearables as what we're paying now. Overall, it's quite more than we're paying now to switch plans. Ridiculous....
