      Got to explore the Alessandro Volta Temple in Como, Italy. Pretty impressive physicist. Invented the first battery back in the 1800.

      Volta's work on the Law of capacitance is the reason the unit of electrical potential has been named the volt.

      Supporting article: http://www.kansascity.com/2013/09/06/4461371/international-expansion-for-sprint.html
       
      If SoftBank/Sprint were to expand into Canada and Mexico, and offer Unlimited Roaming Data, with a an industry first Transnational voice+text+data Plan, wouldn't that be the most amazing thing ever?
       
      What would those specifics be? Isn't there still a CDMA1x network still in operation in Canada? Couldn't Sprint buy out that network?
       
      Rundown of Canadian Wireless Industry = Not Good - http://www.michaelgeist.ca/content/view/6803/125/
       
      And in Mexico, a CDMA1x/EV-DO carrier is still active, with an iDEN network as well...
       
      The 2.5Ghz frequency is has been open for business in Mexico for quite some time... Will Sprint buy that too? It it available for telecom use in Canada?
       
      My post is not well thought out. I don't want to take the time to research compatible frequencies.
       
      So help me out. I have the idea, now as a community, help build out this transnational vision!

      Hey all cant find anything searching the Forums. So I am wondering if someone can help me out here.
       
      I currently have a Belkin N750 DB Wifi Dual Band N+ Gigabit Router and an Airave unit. Both units are right next to each other.
       
      My home is about 1500sf ft.
       
      Using both bands on the router; 2.5ghz and 5ghz.
       
      Since PCS is at 1900 I am correct to assume this is close to 2.5gbs aka 2500?
       
      During they day my wireless signal drops to just about nothing that is usable by my TIVO, Note2, Sony 3100 BluRay Player or Wii etc etc etc.
       
      How likelly is it that the 2 units are severely interfering with each other?
       
      What distance should I place one from the other?
       
      Thanks for the feedback.

      Welcome to the Way Back Machine.  Came across an old AMPS Promotional Video.  Pretty entertaining.

      Some cute holiday videos from the android team.
       
      Notice the Nexus 10 docking station!!!! in the 2nd video about the 1:14 mark.

    • At least a few sites in STL are now at 100 MHz.
    • 100 MHz n41 is live in Austin and...Bentonville, Arkansas. Guessing this went live on Tuesday or Wednesday in Austin; network was acting a bit wonky on Tuesday. Noticed it yesterday, as I'm still a little too far away at home to catch n41. Peak speed in Bentonville 1/3 mi from the site was 675-700 Mbps down, 80-90 Mbps up, with the upload speed only possible with a 20 MHz B66 anchor...which seems congested at times. They also have 5 MHz B2 here as an anchor, which predictably leads to slow uploads. n71 is 15x15 here. Sprint B25 is two 5x5 channels. Weirdly, seems like I'm being routed through Nashville, so latency is rather high, and tethering performance is somehow quite poor...maybe it's due to congestion on the PCC meaning that the difference between on-phone and tethered priority is the difference between a usable connection and...not. Also, VZW (with the old Alltel SID for CDMA) is what you end up using inside the Crystal Bridges museum, though the area has WiFi so not the end of the world.
    • The Sprint site at 520/202 was decommissioned a few weeks ago. Everything was pulled off the pole. 
    • It looks like N5 supports 5, 10, 15, and 20 MHz channel widths. I wonder how long they'll wait before they make a change to be able to use more of that spectrum for N5. Possible options I see: Use 15x15 as B26/N5 using DSS (If thats an option, or would it have to match and be N26?) 5x5 as B5 LTE for older phones and that still leaves 5x5 for HSPA.  A more aggressive option would be to use 20x20 for N5 exclusively and 5x5 for HSPA. This still leaves 10x10 B12 and 10x10 B14 for older phones for low band. Hopefully they enable SA if they go this route. Since I believe you can't aggregate low band LTE with low band NR in most cases, phones using the N5 carrier would not be touching the B12 and B14 carriers. If they enable SA on the 20x20 N5 carrier it would also help free up their limited midband spectrum for older non-NR phones. That would also prevent falling back to LTE only inside a building just because the mid-band anchor band was too weak. In Daytona AT&T was broadcasting 5x5 B2, 10x10 B66, and 10x10 B30 and that was it for midband. 
    • I've found 2 decommissioned Sprint sites in Louisville, both were sites with both T-Mobile and Sprint. In both cases all Sprint tower equipment including the rack were removed. I haven't had time to dig through our permit site to see if I can find anything, but I'll be surprised if I do.
