Oh noes! Not life circa 2002 BS -- Before Smartphones. Walkman. FM radio. MP3 player. Whistling while you work. AJ

Or, heaven forfend, you actually could earn your employer's pay by doing work -- instead of text messaging and generally fiddling with your smartphone every few minutes. And if you need to make/take an occasional personal call, there is this invention called a landline office phone. As for locked down corporate Wi-Fi, maybe there is a reason for that. Employers want workers working, not messing around. I suspect many employers rue the day that smartphones became a common employee belonging and would prefer that wireless service not penetrate their office buildings. AJ

Swiftel in Sioux City in July: AJ

Uh, yeah. SINR (dB) = Signal (dBm) ÷ [Noise + Interference] (dBm) AJ

Sprint can pry Framily out of your cold, dead hands? Okay. Your proposal is acceptable. AJ

The Nexus 5X has a highly smudge prone screen. Clean it, then 30 seconds later, it is smeared again. All reportedly use Corning Gorilla Glass 3, but the 2014 Moto X and 2015 Moto X Pure Edition stay clean far better than does the Nexus 5X. Maybe differences in oleophobic coating quality are at issue. I am ready to move on from LG in the Nexus line. AJ

An interesting loophole of sorts in the AT&T GoPhone $2/day plan plus the $1/day 100 MB data package add on is that AT&T does not debit the $2 base plan charge if no outgoing calls are made or SMS sent. Only the $1 data package add on gets debited from the prepaid balance. So, that is basically equivalent to a pay per use data only plan on the AT&T network at $10/GB or $30/mo for 3 GB. Alternatively, for use of the AT&T network twice a week, that amounts to only $8/mo. AJ

Uh, yeah, invite them. Cut their bills in half. Only $225/mo. AJ

I see that you do not have answers to my questions. Instead, you just hide, lurk, and "like" posts that also are wrong in their thinking. How intelligent and forthcoming -- now, that is irony. AJ

I do not see regularly any Sprint fan boys like that, especially at S4GRU. If they exist, they must be fewer and farther between than T-Mobile fanboys. Or, at least, less vociferous and virulent. No, there really is no comparison. Aggressive T-Mobile fanboys take trolling to a new level. Unlike some of us, they do no important work in or for the wireless industry. Rather, they just snipe from the peanut gallery in nasty, juvenile, anti intellectual ways. Seriously, have you viewed comments or posts at Fierce Wireless, Howard Forums, etc., recently? They invade upon any mention of Sprint. They shout down anyone associated with S4GRU. They have no idea what legitimate work goes on here at S4GRU. Or, if they do, they are envious that such a body of work exists for Sprint, not T-Mobile. And some likely were former Sprint subs who wanted to air Sprint complaints at S4GRU but were told to do so elsewhere or were banned. Now, they hold a grudge over a wireless provider. How immature. AJ

Do tell. Where or what is the "irony"? Do you know the actual meaning of "irony"? AJ

The T-Mobile fanboys view this like a sports competition. "Your team was eliminated. Ha ha. That means my team is better than your team." It gives them an illusory feeling of superiority. AJ

That is an ignorant thing to say on at least two counts. First, 3 dBm is 2 mW. So, that is something. But, second, that is not what you actually intend. You really mean 3 dB, not 3 dBm. And you still think that 3 dB is "nothing"? Is the difference between two scoops of ice cream and four scoops of ice cream "nothing"? Is the difference between $100 and $200 "nothing"? Is the difference between 60 mph and 120 mph "nothing"? Those are all 3 dB differences. AJ

Who? iPhoners? As a matter of course, Android USCC variants seem to exclude/excise band 41, possibly at USCC behest. AJ

Because they just do not. USCC roamers inbound on Sprint do not get to use band 41. AJ

All firmware dictated. Only one hardware variant. AJ

No. Do you lose coverage when you are moving 70 mph in a car? AJ

You guys are unfairly negative toward Sprint. You cannot compare VZW, AT&T, and T-Mobile spectrum swaps, which were almost exclusively AWS-1, to Sprint spectrum swaps, which are entirely PCS. Apples to oranges. That AWS-1 was largely overflow spectrum. For years, VZW and AT&T had put it to use minimally, at best. And even in the case of T-Mobile, some of that AWS-1 was excess from the spectrum it received in the failed AT&T-T-Mobile merger and the consummated T-Mobile-MetroPCS merger. Horse trading and rearranging AWS-1 was easy. Doing likewise with PCS is difficult -- because that is Sprint's primary band for current operations. Sprint's overflow spectrum is BRS/EBS, but CDMA2000 operations cannot be shifted to that band. So, in any spectrum swap, Sprint has to reduce CDMA2000 or relocate it on the fly. Furthermore, beware what you wish for. Say that Sprint has a PCS A/B block 15 MHz FDD (30 MHz) license in a given market, as it does in many markets nationally. Should Sprint give up a 5 MHz FDD (10 MHz) disaggregation just so that it can get the PCS C5 block 5 MHz FDD (10 MHz) disaggregation to combine with the adjacent PCS G block 5 MHz FDD (10 MHz) license? What about five years from now? That PCS A/B block could be a 15 MHz FDD carrier. But you rather would trade away some of that valuable spectrum? AJ

My point is -- for the sake of calculations -- you consider "unlimited" to be 100 GB. Just take the price of any "unlimited" plan and divide by 100. That is the cost per GB. AJ

At the high end, do not use "unlimited" data for comparison -- because the cost per "unlimited" GB asymptotically approaches zero. Instead, use the greatest common factor, which is 100 GB due to VZW. Consider "unlimited" to be 100 GB. Anyone who uses greater than 100 GB of mobile data should be smacked upside the head for being ridiculous. And do not exclude the AT&T DirecTV "unlimited" data bundle -- if that is the least expensive way to obtain 100 GB, go with it. AJ

EV-DO is unlikely to linger into the 2020s. It should be sunset within the next 2-3 years. For CDMA1X, in the many markets where Sprint holds an intact PCS A/B block 15 MHz FDD license, Sprint might be able to squeeze a single CDMA1X band class 1 carrier alongside a 15 MHz FDD band 25 LTE carrier. 1.25 + 13.5 = 14.75 That feasibility is questionable, though, since it would leave only 0.25 MHz for guard bands divided three ways -- at the bottom of the block, at the top of the block, and in between CDMA1X and LTE. However, both AT&T and T-Mobile have been aggressive in reducing/overlapping W-CDMA skirts and stuffing GSM channels into internal guard bands. Sprint may be able to do likewise. AJ

This highway map does not show elevation levels. Why? Because it is not a topographic map. Obvious answer is obvious. AJ

For CDMA1X, the carrier channel hashing algorithm is MIN/MDN or ESN based. For EV-DO, it is data session based. With CDMA1X, if your MIN/MDN or ESN hashes to a high Fx, your handset can camp on different carriers a lot from site to site. My MIN/MDN almost always hashes to F1, sometimes F2 if many carriers are deployed on a site, so my handset does not camp on different carriers very often, since F1 is the first to be deployed on every site. All of the above relate only to idle state, controlled by the handset invoking the hashing algorithm. In traffic state, though, the network can redirect the handset to any carrier in any band. AJ

Use the engineering screen shortcut in SignalCheck Pro. And logs will not help much, since your handset always will hash to the same CDMA1X carrier on each respective site. The carrier changes are not dynamic, unlike with LTE. http://s4gru.com/index.php?/blog/1/entry-318-can-toggling-airplane-mode-actually-improve-your-3g-data-speeds/ AJ
