I am not certain of this, but some of the antenna elements may be horizontally polarized, others vertically polarized. AJ

Hi Jim... Welcome to S4GRU. We are well aware of the changes involving the loss of pseudo native coverage from Nex-Tech, United, and PTCI. In fact, we started a lengthy thread here about a month ago that has extensively discussed the issue. So, in a moment, I will be removing this thread and merging your post into the existing thread. Now, that said, if you live in Rush County, you should not have remained a Sprint sub, as Rush County is a Nex-Tech market. My guess is that you retained your Sprint number from one of your previous home locations in a native Sprint market. Is that correct? AJ

Rumor has it that C Spire may abandon its Lower 700 MHz band 12 LTE ambitions altogether because of the interoperability and economy of scale problems. AJ

Previously, like bigsnake, I suggested that SoftBank-Sprint-Clearwire divest its EBS leases following the WiMAX shutdown, simply because the leases are too volatile and the spectrum is in excess of what the merged operator needs. But I have changed my tune in this regard. Ideally, I would prefer that the FCC allot spectrum to operators on a periodic basis according to market share. Let the operators compete on service and price, not on bandwidth. But using the numerous T-Mobile spectrum acquisitions over the past year as a model, the FCC seems to be allowing the underdog(s) to acquire highly disproportionate amounts of spectrum as a competitive measure against the duopoly. So, if it is good for T-Mobile, then it should be good for Sprint, too. And I now hold the position that SoftBank-Sprint-Clearwire should be able to retain all of its BRS/EBS spectrum. AJ

LightSquared founder Phil Falcone comments on Tim Farrar's blog in a bit of a showdown between the two. Interesting... http://tmfassociates.com/blog/2013/05/09/another-sucker-bites-the-dust/comment-page-1/#comment-1356 AJ

Yep, in addition to directionality, multiple antennas are key to dBi gain. AJ

Please clarify. I am not really sure what you are asking. AJ

I would "speak softly and carry a big spectrum analyzer." AJ

Actually, she is out of a job at T-Mobile. So, she may need some work. I would guess that could bring in some donations here at S4GRU. AJ

All of the above is accurate. The site location does not matter. The technology does not matter -- Sprint/Clearwire could deploy iDEN 2600 if it wanted to do so. It would merely need to produce token demonstration that the sites in question provide "substantial service." In the end, the FCC really lacks adequate staff to police "license protection" coverage. And it has yet to take me up on my offer to become the full time Spectrum Czar. AJ

Whoa, whoa, whoa. Is there something other than the legendary Galaxy Note 2 in the digiblur household? AJ

Not to rain on your parade, but this is, honestly, nothing new. We have a similar VZW propagation graphic posted somewhere here in the archives at S4GRU. Both cases are using a simple free space path loss formula. The nutshell of it is the inverse square rule. Take the ratio of one frequency to another. Use the inverse (i.e. the reciprocal). Then, square that value. But free space path loss is a theoretical model. Empirical formulas tend to better model RF in real world environments. For example, Okamura, Hata, and COST are some well known empirical models. You can start with a little bit of "free space" research at Wikipedia. http://en.wikipedia.org/wiki/Radio_propagation_model AJ

Right. But maximus was not calculating total coverage area. Instead, he was creating a ratio (i.e. a comparison), in which case the π on both sides of the ratio would cancel. So, the square of the radius gives us the appropriate ratio for the 2-D propagation model in use. AJ

Fraydog has been on top of similar topics. So, he gets my nomination. AJ

So, wait, am I the one with the brains or the brawn? Aw, you know what? Scratch that. I will trade both for a couple of West End Girls. AJ

Here are a few more ideas for tag lines: "My Ec/Io is better than your Ec/Io." "I know what S4GRU did last summer." "Hey, baby, want to see my custom PRL?" AJ

Wait, what happened? Where am I? What year is it? Are you Agent J? AJ

Yeah, I could definitely use an outfit like this... Just replace "SWAT" with "S4GRU," and that might help keep the authorities off my back when I am out gathering network data. AJ

I would probably riff on the "Don't come a knocking..." meme. We could do "Don't come a knocking, cellular mapping is rocking." AJ

Can I get some S4GRU underwear from Kmart with my name on the inside? AJ

My apologies, as I sound like Johnnie Cochran, but either way, my guess is that the band plan will be a mess. Qualcomm wants an FDD band plan and makes some persuasive technical arguments in its favor. Prima facie, the TDD band plan makes more sense and seems more feasible, but I am not sure that I have enough technical expertise to evaluate it fully. AJ

Hmm, now, why would a "weatherman" think that way??? I kid, I kid... AJ

Have you decided what your next endeavor will be? Maybe watching laundry tumble in a dryer or counting cards at the blackjack table. AJ

And what you will see on non SVDO devices is a bounce back and forth between CDMA1X and EV-DO every few seconds. On most networks, CDMA1X is configured for a slot cycle index 2, which equates to a sleep/wake cycle every 5.12 seconds. The idle device will sleep, then wake every 5.12 seconds, and that is why the engineering screen will update your RSSI and Ec/Io every 5.12 seconds. While the CDMA1X side is asleep the EV-DO side will wake, and I cannot recall if I am thinking of my EVO 4G or my Samsung A900 flip phone, but some CDMA1X engineering screens will show the periodic flip between CDMA1X and EV-DO carrier channels.

Have you memorized the phone book yet? AJ
