  1. Yes, I found the Android Signal Info app and RootzWiki thread about six months ago -- back when the app still had to be side loaded. I have mixed feelings about it. I am not a programmer, so I respect the effort "yarly" put in to create an app himself. However, the app has some shortcomings. Its RSRP and RSRQ figures are already available via the internal debug screens on various handsets. And its RSSI calculation, which uses a questionable (RSRP − RSRQ + 17) formula, is predicated entirely on one particular LTE carrier bandwidth: 10 MHz FDD (e.g. VZW in all markets, AT&T in some markets), but not 5 MHz FDD (e.g. Sprint in all markets, AT&T in some markets). So, the app purports to be carrier agnostic, but it really is not. For LTE, it is geared toward VZW, as "yarly" is a VZW user. Additionally, "yarly" seems to misunderstand the SNR (signal to noise ratio) metric, as he quotes in the RootzWiki thread SNRs on the order of 300 dB. For a radio link, a 300 dB SNR is basically impossible -- that is a 10^30:1 ratio. "yarly" does not seem to get that the SNR reported is multiplied by 10. So, that "300 dB" SNR is actually a 30 dB SNR, which is extremely good. AJ
  2. Whether Sprint installed it or the hospital did, I would bet on a bidirectional amp and leaky coax. If so, unless the amp bandwidth includes the PCS G block (unlikely), LTE will not benefit. AJ
  3. Meh, I was hoping for the "Walk of LTE." AJ
  4. The EVO LTE is not a great LTE performer -- at least, not in a fractionally deployed market. Start reading, as we have discussed this issue ad nauseum. AJ
  5. Sprint is waiting for Michigan to take off the child's mitten and put on an adult's glove. AJ
  6. You had a "strong 4G signal"? How do you know? And you may have inverted your downlink/uplink data rates. AJ
  7. DDoS'd is the new "rained blows upon him." AJ
  8. Yep, I asked Brian Klug at AnandTech last week. No dice. I was disappointed. AJ
  9. Are all the new members USCC users in Chicago, St. Louis, Ft. Wayne, South Bend, Springfield, and Champaign who want to know more about their soon to be new overlords? AJ
  10. Wait, we gained 800 member in less than a week!? How??? AJ
  11. I kid, I kid. I have had the same thoughts about the Nexus 4. I am currently down to just my longterm Sprint line, but I would like to add another carrier for diversity. I refuse to do business with anti competitive asshats VZW and AT&T, so that leaves me with T-Mobile or various MVNO/prepaid carriers. The price is right, and the Nexus 4 could be a nice fit for a 3GPP based MVNO/prepaid. However, it reportedly lacks access to any RF engineering screens. That rules it out for me. AJ
  12. I guess Google and all the other interested buyers happened to "pull the plug" on your plans. AJ
  13. We need to be careful. Little good can come from the direction this discussion is going. AJ
  14. ...only people who have crimson skin below the head but above the shoulders. AJ
  15. Oh, I know. I am just riffing on your use of "pull the plug," which has become associated with dying. I think the idiom you intended more was "pull the trigger." AJ
  16. I do not know how this post escaped my watch. No, Robert, do not pull the plug. We would miss you too much! AJ
  17. Yeah, "buffet bloat," that is the feeling you get after eating at Sizzler. Oh, wait, you said "buffer bloat." AJ
  18. ¿Dónde está la playa? ...o... ¿Quién es la playa? AJ
  19. You have stated your opinion plain as day more times than necessary. You have had your voice on the matter. Now, stop the rants, and tone it down. Or face the consequences. Is that clear? AJ
  20. It uses VoIP with EV-DO as the Internet connection. Any Internet connection with high enough throughput and low enough latency can be used for VoIP. AJ
  21. Yes, that is basically the only way to get Sprint sites to handoff to USCC sites (and vice versa). And it would be highly impractical, as Sprint and USCC would have to harmonize their two networks (MSCs, PN offsets, neighbor lists), only to tear down the USCC network in two years. So, probably not gonna happen... AJ
  22. I probably should have included this in my article on The Wall. Instead, I added it as a comment to my article: In short, Sprint and USCC can refarm the guard band between their adjacent licenses into a CDMA2000 carrier in the PCS 0400 carrier channel assignment. http://s4gru.com/ind...road-shoulders/ AJ
  23. The 949 GB per month figure is an ideal statistic never even approached in the real world. A more meaningful real world estimate would be something on the order of 300 GB per month for a single sector⋅carrier. And as Sprint has 56 million subs, each sector⋅carrier has to support on the average about 250 subs. So, a few users sucking up even 10 GB per month each could put a big dent in the remaining capacity of that sector⋅carrier. AJ
  24. This may sound silly, but I am completely serious. You probably ought to move. If your local wired ISP provider(s) cannot meet the needs of your business, then you may need to relocate. This should be no different from any other job or business. People move for better jobs and businesses relocate for better opportunities all the time. This will be a growing trend. People who rely on the Internet for work will need to choose places to live that have strong broadband infrastructure. AJ
