Somebody could go back and check if T-Mobile rounded off and reported the porting ratio as 2.5 last quarter. I would not be surprised. If so, yes, the decision to add another decimal place would be statistical manipulation to show that the porting ratio "moved" in T-Mobile's favor. AJ

Robert is correct. The recent porting ratio is not good for Sprint, but there is no "oomph" to a change from 2.45 to 2.50. To put the math in more practical terms, the porting ratio indicates that for every 100 subs who ported from T-Mobile to Sprint, another 250 ported from Sprint to T-Mobile. Previously, that latter figure was 245. Absolutely insignificant. AJ

Close. USCC still has a few PCS only markets -- Omaha is the most notable. So, the LTE overlay is not entirely band 5. AJ

Actually, because it wanted to offer the iPhone, USCC distanced itself from band 12. USCC has overlaid some iteration of bands 2/4/5 across most of its LTE markets. AJ

Yes, that is the "improper use" I allude to in my previous post. AJ

Maybe, but do not count on that. Pseudo native coverage often enables improper use -- informally called "perma roaming." That may not be such a big issue with EV-DO now that it has been deprecated in favor of LTE. However, it will be an issue with LTE. AJ

I happen to have an archival photo of David's workspace: AJ

You forgot band 12, which AT&T has in part capitulated to do for MFBI. AJ

Overall size will be about halfway in between the 2014 Moto X and the Nexus 6, so take that into consideration. And tested RF performance looks average to good, just not outstanding. We did not have time to cover those issues in this teaser article, so we may run a follow up. More likely, though, we will discuss them in greater detail in a dedicated thread in The Forums. AJ

We are not discussing that here any longer. We are discussing it in this thread: http://s4gru.com/index.php?/topic/7080-wahoo-us-cellullar-and-other-ev-do-roaming-is-live/ AJ

Wahoo! We caught it! AJ

Gotcha. VZW Kansas City is SID 59, not SID 12. But it would not have shocked me if VZW had consolidated many SIDs across the center of the country. AJ

That is not in Overland Park, is it? Where did you take that screenshot? AJ

No, there really is not any reason for this Sprint "UC1" variant to have included band 29 for supplemental downlink carrier aggregation on AT&T. That capability is already covered on the aforementioned "UC2" variant, which will be the unlocked version, the T-Mobile variant, and/or the AT&T/T-Mobile omnibus variant. AT&T handset LTE band future proofing is a hot mess right now. Some AT&T handsets include bands 29/30, some include only one or the other, and some include neither. The only consistency is inconsistency. A Sprint variant has no need to get mixed up in that muddle. AJ

Do you recall any correlation between that native CDMA1X + roaming EV-DO split and SVDO handset capabilities? In those handsets, CDMA1X and EV-DO were on separate RF paths. The native + roaming split does not seem to happen often, if at all on modern single RF path handsets. AJ

No complaining at S4GRU. Consider yourself warned. The "f*** you Sprint" and "heads out of their ass" are unwarranted. You do not get to break the rules and talk like that here. http://s4gru.com/index.php?/topic/1197-s4gru-posting-guidelines-aka-the-rulez/ Sprint is not obligated to build out its network to suit your needs. That just may not be cost effective. The same goes for large roaming quotas. Sprint may not be able to afford the hundreds of dollars that you could rack up in roaming data charges. And even though you claim that you would pay per MB, would you be willing to pay, say, $.10/MB? Because that is in the range of what Sprint pays for roaming data. If Sprint does not provide you with sufficient coverage, go right on over to VZW or AT&T. We do not care. The duopoly has paid hundreds of billions of dollars to buy up 30 years of wireless network deployment. You will pay their rates to support those acquisitions, and you will abide by their policies. Enough said. AJ

Staff discovered the roaming map coverage change about an hour ago. We are investigating. So, let us table any discussion until later tonight. AJ

That is the full handset diagonal, not the display diagonal. All told, this handset is about 5 mm smaller in both length and width than the Nexus 6. Or, to put it in another perspective, it is about 10 mm longer and 3 mm wider than the 2014 Moto X. AJ

Not if the two intra band carriers require separate RF transceiver ports. And not when the two carriers exceed 20 MHz of aggregated bandwidth. The first may be an issue. The second definitely has been a limitation. You might be surprised. The signal levels between the two carriers may be close, but they rarely will be exactly the same. AJ

Other domestic operators' CA is a different animal -- inter band CA between low band and mid band spectrum. Sprint is the only one pursuing intra band CA, and it is in high band spectrum. So, in a jack of all trades Nexus handset, do not rule out Sprint capable CA, but certainly do not count on it. AJ

Then, you think wrong. WiDEN was little more than a bandaid on iDEN. It was both a stopgap and a dead end technology. That is why Nextel acquired BRS/EBS spectrum and experimented with Flash-OFDM, which then got absorbed into and usurped by WiMAX and LTE. Any way you cut it, iDEN was going the way of the dodo. In fact, it might have happened sooner if Nextel had remained an independent company. AJ

Comprehensive LTE band coverage is guaranteed -- because the combination of AT&T and T-Mobile will require bands 4/5/12. Band 41 CA is no given, however. AJ

Fe fi fo fum, Project Fi and roaming, hmm? AJ
