    About a decade ago, Sprint was the cat's meow with the most technologically advanced network and the coolest handsets in the US. Then, VZW started pulling together the disparate pieces from its formative merger and flexing its economy of scale. And Cingular did likewise by slurping up AT&TWS. That was the beginning of the current epoch in the domestic wireless industry. Now, Sprint carries the stench of years of struggles following those mergers and its unsuccessful Nextel merger in an attempt to keep pace. That is what people with no frame of reference or short attention span know about Sprint. AJ

    I have no problem with CDMA1X and EV-DO using different signal indicators. In fact, even though I can easily tell them apart via engineering screens, I would prefer different indicators. But those do not make CDMA1X "2G" and EV-DO "3G." AJ
  3. WiWavelength
    ...because both CDMA1X and EV-DO are "3G." You need to read more posts. AJ

    For some reason, I am imagining Gov. George Wallace...er, I mean...Nextel CEO Tim Donahue standing in the doorway of a Nextel MSC somewhere in the South on June 30, trying to block the shutdown. AJ

    As I have expressed many times, I do not get the fascination with the PCS/AWS-2 H block. If Sprint can get the spectrum for cheap, fine. However, it seems like a lot of trouble for only 10 MHz of spectrum. Current dual band panels may not support it, and current RRUs definitely do not. So, is it worth supplementing or replacing panels and/or RRUs so soon after Network Vision deployment just for one 5 MHz FDD carrier? And not only infrastructure would have to be upgraded but also devices would have to be, too, as the H block would require yet another band revision. All in all, if Sprint were to win a large collection -- or even the entire set of H block licenses -- by next year sometime, I would not expect any usage until the 2016 timeframe. In the meantime, band 41 TD-LTE in BRS/EBS is primed and ready to go. AJ

    Yes, but Sprint is still licensed that spectrum on the US side of the border. Sprint just may not be able to use much of it. AJ

    There is basically no way that happens. Even if the PCS/AWS-2 H block were to be auctioned alone, an auction taking place by the end of this year would have been announced already. Look to 2014 -- at the earliest. AJ

    And, following SMR 800 MHz rebanding, the US primary (i.e. US exclusive) spectrum will shift down to the lowest 6.25 MHz FDD (806-812.25 MHz x 851-857.25 MHz). That is obviously designed to protect Public Safety, which is moving to that low end of the band. But it does nothing to help Sprint, which is moving to the high end of the band (817-824 MHz x 862-869 MHz). AJ

    Yeah, either current or repurposed AWS-4 would not make long term sense for fixed wireless. Not enough bandwidth. But, for mobile use, if it were repurposed along with the LightSquared uplink, I think Ergen would have to give up the existing AWS-4 downlink (2180-2200 MHz). And maybe that could be rolled into the proposed AWS-3 downlink (2155-2180 MHz) as supplemental downlink. AJ

    No, the above idea gets bandied about a lot, but I highly doubt its veracity. Yes, DBS may be the only option for many rural customers. However, that does not mean DirecTV and Dish have the majority of their customers in rural areas. I do not have numbers at my disposal, so I would love to see someone prove me right or wrong. My educated conjecture, though, is that most DBS subs still live in urban areas, and they simply choose DBS as an alternative to cable. Thus, on a fixed wireless basis, a great many Dish subs could also be served by the existing or slightly expanded Clearwire network. As for comparisons to existing or previous fixed wireless services, those are largely irrelevant. They represent the past, not the future. Take 100 MHz of BRS/EBS spectrum, deploy LTE Advanced with 4x4 or even 8x8 MIMO, and fixed wireless could give cable broadband a run for its speed and money. Unless I am sorely lacking in my understanding of cable propagation, MIMO is not an option for cable. Now, I will not speak to the chances of success for such an endeavor, but it certainly would be doable. And that seems to be what Ergen has been thinking, too. AJ

    No, not "useless." First, LightSquared's spectrum consists of multiple satellite spectrum allocations in between 1500 MHz and 1700 MHz. It is perfectly useful for continued satellite use. Second, for terrestrial use, LightSquared configured its spectrum with an inverted duplex: the downlink is lower in frequency than the uplink. Additionally, for carrier aggregation, the downlink features two 10 MHz FDD carriers, while the uplink is limited to one 10 MHz FDD carrier. For an illustration, see the Javad graph below: As configured, the downlink is what swamps GPS; the uplink does not. So, the uplink potentially could be repurposed with other spectrum, such as AWS-4. For example, take the AWS-4 uplink (2000-2020 MHz), which is adjacent to and problematic with the PCS/AWS-2 H block downlink, then convert the AWS-4 uplink to downlink. The H block problem goes away, and the AWS-4 uplink converted to downlink could be paired with the LightSquared uplink in a traditional duplex. Moreover, the downlink carrier aggregation configuration would remain with two 10 MHz FDD downlink carriers and one 10 MHz FDD uplink carrier. AJ

    Maybe that is why digiblur has such capacity issues. It could be the constant stream of accidentally flushed phones that end up floating down the Mississippi past Baton Rouge. AJ

    Oh, not many. Geography and Film. Not as many as I probably should have, nor as many as some might assume I have. But, without revealing too much, I have some psychological characteristics that do not play well with the bureaucratic nature of higher ed. Thus, I do not throw around credentials. Instead, I hope that my demonstrated knowledge and intelligence speak for themselves, as I am probably best described as a polymath and autodidact. AJ

    Considering that the South has been an iDEN stronghold, roadblocks and mobs against the SMR Rights Movement would not surprise me at all. AJ

    I still say the iDENites reported the auction to eBay in an attempt to sabotage it. AJ

    I know. I have a degree in geography and was just making a geography joke. Compare most any dot map -- cellphone usage, tweet location, Chinese restaurants, or even crimes committed -- to an actual image of the US at night from space, and you will see strongly positive correlation. It is all related to population density. But, yes, you are right that the different OS layers of the map do present some interesting differences. In my local market, Kansas City, for example, iOS predominance positively correlates with wealthier residential areas and business districts within the metro, while Android predominance positively correlates with po' parts of town. And I could readily point that out in other markets, too. AJ

    If I eat something that disagrees with me, I sometimes experience a Cornhole Mass Ejection. And those do travel surprisingly fast. AJ

    Keep it up guys, and this thread is soon getting retitled "Box talk." In the meantime, what if you never got to see her "box"? AJ

    Indeed. I guess HTC just could not get Anthony Michael Hall, Judd Nelson, or Ally Sheedy. AJ

    I will let Robert make the more definitive statement if he chooses to join this discussion. But 100 Mbps symmetrical fiber is low from what I recall hearing and reading here at S4GRU. My recollection is that roughly 200 Mbps is the baseline for backhaul capacity. Now, that said, you are correct that 100 Mbps should be sufficient in actual practice for three sectors deployed with one 5 MHz FDD LTE carrier along with at least one CDMA1X carrier and at least one EV-DO carrier. The three LTE sectors, for example, are never going to run full tilt simultaneously, since unity frequency reuse causes them to interfere with one another to some degree. But that would be just scraping by with the bare minimum. We have to take into account the 5 MHz FDD LTE 800 carrier, maybe even a second 5 MHz FDD LTE 1900 carrier, and the CDMA1X 800 carrier. While it does not make sense to overpay to over provision backhaul, if Sprint is once again under provisioning backhaul, then we are in for more of the same old trouble. AJ

    Uh, have we not all seen this map many times before? It is just the US at night from space. AJ
