I happen to have a Movado right here that you can have. It has been kept warm for you. AJ

Oh, you are absolutely right. Omaha has been an interesting case study for me for over a decade. About 10 years ago, of any city in the world, Omaha may have had the greatest number of CDMA2000/cdmaOne networks: Alltel (Aliant), VZW (US West/AirTouch), Sprint, Qwest, and Cricket. Then, USCC acquired some PCS spectrum and even entered the fray. But I am unsure whether USCC's entrance and Qwest's departure overlapped. I think they did, in which case, Omaha had fully six CDMA2000/cdmaOne networks at one point. Moreover, GSM did not enter the Omaha market until very late, circa 2002, with the original AT&TWS' GSM overlay, followed by T-Mobile's license protection network, circa 2003. So, for a number of years, Omaha was a GSM black hole. Even today, the best thing that GSM has going for it in Nebraska is only Viaero. AJ

And AT&T has a relatively puny PCS 1900 MHz based footprint in Nebraska. Unfortunately, Omaha is outside the top 50 markets, so we have not seen any market share data. But I would be willing to wager an educated guess that VZW is way out in front, Sprint is second, and AT&T is a distant third. Cricket, USCC, and T-Mobile would make up the remaining market share, but T-Mobile operates only a license protection network and does not actually sell service in Nebraska. Long story short, AT&T is operating a 10 MHz FDD LTE network in Omaha with likely fewer subs than Sprint. So, with twice the carrier bandwidth and less loading, higher speeds on AT&T are likely. AJ

That is right. I am going to keep hammering away at you non proofreaders until you learn your lesson. AJ

Those signal bars are indicating your son's CDMA1X signal strength, not his LTE signal strength. With rare exception, signal bars are not to be relied upon for LTE signal strength, nor are they a good metric overall. They are there just to placate the masses. AJ

Dish Trialing Mobile TV service on 700MHz Block E
WiWavelength replied to bigsnake49's topic in General Topics
3GPP likely started the standardization process before AT&T had to dispose of much of its AWS. Additionally, Canadian operators will likely aggregate band 29 with band 4. The difference between an 1800 MHz uplink and a 1700 MHz uplink is negligible. The same holds true for a 1900 MHz downlink and a 2100 MHz downlink. Furthermore, PCS and AWS service rules are practically the same. AJ -
Dish Trialing Mobile TV service on 700MHz Block E
WiWavelength replied to bigsnake49's topic in General Topics
First, "they" would be 3GPP, not AT&T. Second, band 4 and band 2 are very similar, so they tend to go hand in hand. AJ -
Dish Trialing Mobile TV service on 700MHz Block E
WiWavelength replied to bigsnake49's topic in General Topics
I still do not follow the "all this work" question. AT&T will downlink carrier aggregate band 29 with band 2. AJ -
Dish Trialing Mobile TV service on 700MHz Block E
WiWavelength replied to bigsnake49's topic in General Topics
What work? AJ -
Not everyone does. And those that do have made a poor choice now. My system is more logical. Anyone should be able to see that. Well, it matters to me because the aggregated spectrum may not be contiguous or even in the same band. I care about noting those details. AJ
-
No way. I strongly disagree. I have had many years to think this through and come up with logical, systematic designations. There is no standardization, but my methodology is among the best that I have encountered. As for the + operator, it needs to be reserved for carrier aggregation. AJ

Dish Trialing Mobile TV service on 700MHz Block E
WiWavelength replied to bigsnake49's topic in General Topics
Yes, WCS is much closer to commercial realization than is 600 MHz. WCS could start showing up as early as next year, while 600 MHz is at least three years distant -- if ever. AJ -
COUNTDOWN!!! Nextel iDEN Shutdown
WiWavelength replied to S4GRU's topic in Network, Network Vision/LTE Deployment
The entries were relatively few, so I decided to wait through Sunday as the actual shutdown date for any additional entries. But, then, I forgot. I will go back through the thread and select the winner tomorrow. AJ -
My first clearwire tower i've seen in overland park, ks

You do realize that, with the juxtaposition of "rim" and "job," you are just setting yourself up for more bawdy banter. AJ -
AT&T LTE Site Spacing Question
WiWavelength replied to shawn_aten's topic in Network, Network Vision/LTE Deployment
Even with Upper 700 MHz propagation and wide open spaces, we are starting to see more clearly the relative fragility of the LTE airlink. Or maybe this "Verzion 4G LTE" is just a knockoff, and the real thing is better. AJ -

Those last two LTE engineering screenshots should be disregarded. The data appears offset by one line, and even then, some of it is not valid. It could be yet another problem for the poorly performing Galaxy Nexus. AJ

Upon site shutdown, the entire S4GRU archive will be available as a brain implant chip, but only for Über Mega Premier Sponsors. AJ

Paynefanbro, I was teasing you a little bit with those previous posts, but I am trying to make a serious point. We need to be consistent with, for example, 20 MHz x 20 MHz or 20 MHz FDD terminology. Those two are acceptable. But "2x20" just leads to potential ambiguity and confusion. So, I am going to edit the title accordingly, also spelling out that "EE" refers to the Everything Everywhere partnership in the UK, as not everyone here is familiar with it. AJ
