  1. And it looks like T-Mobile data speeds were 14 Mbps downlink, 17 Mbps uplink. That network is becoming imbalanced. AJ
  2. If the new band gets standardized, yes, it appears that the PCS/AWS-2 H block uplink will be left fallow. And the PCS A block licensees may prefer it that way. The PCS duplex gap started as only 20 MHz: 1910-1930 MHz. With the addition of the PCS G block, that cut the duplex gap down to 15 MHz. The PCS/AWS-2 H block would cut the duplex gap down to only 10 MHz. In other words, the PCS/AWS-2 H block uplink would be only 10 MHz removed from the PCS A block downlink, and that could cause some interference. AJ
  3. As I like to say to myself, "Oy vey. Canta y no llores. Porque le falta." But that mish mash is just me. AJ
  4. Warning: you just got suckered into buying Bose. No, mere consumer, Bose is not the "best." It has not been the best forever, even ever. And Amar now has been dead for two years. http://www.nytimes.com/2013/07/13/business/amar-g-bose-acoustic-engineer-and-inventor-dies-at-83.html?_r=0 Bose is like Monster Cable. AJ
  5. Too bad. We all are looking forward to hearing your high pitched Dan voice in full fidelity. AJ
  6. CellularInfo is almost enough to make me want to get an iPhone. When it comes to wireless info, I'm just weak. I'm weak! Happy Festivus… AJ
  7. Downtown would be a good idea. The current macro site location at the southern edge of downtown is not ideal in this high speed data day and age. It shoots longitudinally down Massachusetts St through a lot of 100-150 year old masonry/brick buildings. In building coverage on the north side of downtown relies a lot on band 26. But as for a downtown DAS, we have no evidence of it. So, it could be Memorial Stadium. AT&T has a temporary or even permanent COW there. It could be the KU campus. KU Information Technology has an extensive outdoor Wi-Fi antenna network -- that probably is broadband enough to host band 41, too. But I think I would have noticed that. Plus, Sprint already is the only operator with an on campus macro site. Maybe it is Rock Chalk Park -- the relatively new KU athletics development on the far west side of town. It is about halfway between the urban macro site at Free State HS and the rural macro site south of Lecompton. A DAS there could make sense. AJ
  8. I am not surprised that T-Mobile lags well behind in Milwaukee. It has been a spectrum constrained market. I am a bit surprised that Sprint beats AT&T, as AT&T has had the benefit of both a Cellular 850 MHz network (Cingular) and a PCS 1900 MHz network (AT&TWS) since the Cingular-AT&TWS merger a decade ago. AT&T may be struggling under the weight of its own market share. And I must admit I am surprised that VZW wins the market. For "3G," Milwaukee is one of VZW's few PCS 1900 MHz only markets. It was PrimeCo before the merger 15 years ago. No AirTouch, no Bell Atlantic Mobile, no GTE. So, band 13 is paramount -- no other low band spectrum. Everything else is mid band. Lastly, while RootMetrics is the best objective testing available, another shortcoming is the failure to test USCC in Milwaukee, Omaha, Tulsa, and Knoxville. Where USCC is a major market operator -- especially where it is a Cellular 850 MHz licensee, such as in Milwaukee -- it should be included in the testing regimen. With the demise of Nextel, Alltel, MetroPCS, Cricket, Cincinnati Bell, et al., most major markets now are down to the big four. But not all markets. And RootMetrics should test the remaining alternative operators in those markets. AJ
  9. Somehow, I missed this in the Sprint press release: http://newsroom.sprint.com/blogs/sprint-perspectives/sprint-improves-its-network-as-competition-heats-up-in-kansas-city.htm I know basically everything about the macro network in Lawrence. But an outdoor DAS? I am at a loss. I do not know where that is, and S4GRU has no record of it. AJ
  10. Appropriate downlink:uplink weighting should be approximately 3:1. That would be 75 percent downlink, 25 percent uplink. Absent mass gatherings, the uplink rarely gets congested. Instead, the downlink gets swamped, while the uplink exceeds it. AJ
  11. I believe I set my Dropbox camera uploads on all of my handsets to go over Wi-Fi only. I do not want those high res images/videos wasting my battery and cellular data. AJ
  12. Sprint recorded the fastest downlink speed, yet it finished fourth in both Network Speed and Data. That almost has to be uplink speed. RootMetrics is unduly weighting the uplink. AJ
  13. People tend to be myopic in their subjective assessments. AT&T works better at my house and my office. Therefore, AT&T overall must be better. It is a composition fallacy -- faulty generalization. AJ
  14. Yeah, well, you can think what you want, but you are not qualified to rank the networks objectively. You are little more than one data point, while RootMetrics is hundreds or thousands of data points. AJ
  15. Unless an enforcement issue, the FCC does not test anything. The OEMs or their authorized RF labs do the testing. The FCC then accepts the results under certification and attestation. Falsifying results could be a federal crime. I do not have time now, but I will address the remainder of your post later. AJ
  16. Guys, you are not being scientists -- you cannot prove a negative. Look, I do not care if 2x CA on band 41 is or is not active on the 2015 Moto X. However, I am a scientist. Citing speed test results and Motorola support tweets does not pass muster. That is my point. The FCC OET authorization filings are the most definitive sources that we have available. Since the LTE engineering screen lacks SCC signal metrics, we cannot determine otherwise. So, just chill out. AJ
  17. And you trust Motorola support to know anything about carrier aggregation? Pardon me while I keel over laughing. That is like asking Sprint customer service about Network Vision site completion. It is naive to think that entry level workers know what you want to know. Maybe the 2015 Moto X truly is broken, does not support 2x CA on band 41, and will not get fixed. But I would not take the word of Motorola support on anything that technical. Instead, I will go with the authorization lab testing that Motorola submitted to the FCC: AJ
  18. Because of its 5 MHz FDD and 20 MHz TDD configurations, Sprint median uplink speeds probably are 10 Mbps or less. Uplink capacity, though, is significantly greater than that of T-Mobile. Sprint has up to five LTE carriers on air. In speed testing, Sprint also has the disadvantage of inherently highest market share in Kansas City. But that did not keep it from winning the downlink speed race. I would think that the Network Reliability metric -- in which Sprint beat T-Mobile -- would factor in those criteria. AJ
  19. For the record, here is the link to the Kansas City 2015 2H report: http://www.rootmetrics.com/us/rsr/kansas-city-mo/2015/2H AJ
  20. And that is a RootMetrics mystery, since Sprint ranked ahead of T-Mobile in most metrics. If this all came down to uplink speeds, that is bullshit. People barely care about uplink speeds. Moreover, T-Mobile median uplink speeds are higher than its median downlink speeds. That network is becoming congested. AJ
  21. Not sure. I think my spectrum analyzer uses a 50 ohm antenna, and it is connected via coax with F connectors. But 50 ohm coax more commonly is terminated with BNC. AJ
  22. Trip, your RG-6 is 75 ohm. Does the booster not recommend a 50 ohm coax? AJ
