  1. My guess, damaged sectors antennas and sites that ran out of backup power. Most sites don't have more than say X hours of backup power. Probably most carries are having similar problems.
  2. Being on eHRDP could affect speeds though if traffic is going to a different packet core no? As long as all the phones are tested over eHRDP it should still enable an apples to apples comparison to be made.
  3. You sure about that, it looks like they are saying it includes the stock JB kernel and gapps. But I'll defer to you since it looks like you're already up and running. Got a rooted kernel you recommend?
  4. Looks like its finally time to unlock my GNEX.
  5. Sounds great. Recording average RSSI, Ec/Io reported on each handset at the each location would be nice also.
  6. CDMA2000 1900/800 and LTE 800. Playing around with a SDR and want to take a look at the signal.
  7. Anyone know how to map the channel numbers to actual frequencies?
  8. Does this menu exsist on the galaxy nexus?
  9. The Cienna kit takes connections from one or many routers and puts them on one fiber using DWDM which is a type of optical multiplexing so that you can have 40 - 10Gb, 4 - 100Gb, or 1 - 400Gb links share one fiber pair between two points up to 9,000KM apart(at lower speeds). It also allows traditional voice circuits(TDM) to share the same fiber as ethernet traffic without the need for using VOIP. This allows Sprint to upgrade capacity without running more fiber or having to replace every component, they simply replace cards on the Cisco routers and Ciena optical shelf on a link by link basis. I am not an optical networking expert so please forgive any errors. http://en.wikipedia.org/wiki/Wavelength-division_multiplexing http://media.ciena.com/documents/ActivFlex_6500_Packet_Optical_Platform_DS.pdf
  10. Ah, Sprint is using the Cisco CRS as their backbone router so no 40Gb ethernet. Looks like 10Gb and 100Gb only for them for now.
  11. Sprints IP backbone currently leverages 40Gb and 10Gb links IIRC, hard to find info. Note that the PR mentioned this Ciena kit being used for wireless and wireline. I don't think sprint is maintaining two IP backbones one each for their transport business and wireless business but it is possible.
  12. Hopefully sprint will have a lot of peering capacity to back this up. Luckily adding peering is the relatively easy part.
  13. Notice I said backbone not backhaul. We are talking about Sprints connections from city to city and to the internet not from tower to tower.
  14. Saw this article this morning. Should give Sprint plenty of headroom for future traffic increases. http://www.lightread...?doc_id=221923 Edit: Full Press release http://www.ciena.com/corporate/news-events/press-releases/Sprint-Upgrades-Network-with-Ciena-Coherent-Optical-Technology.html
  15. Yes, I read the document, they are planning on overcoming the technical issues by routing all of your traffic through a box/boxes owned by the wireless carrier that would act as a proxy for your device. This makes me nervous. I'm not sure anyone will implement this due to cost, not to mention how upset would you be if that box stopped working and you could no longer use wifi or 3G/4G to connect. Its a lot of overhead for a very small benefit. IPv6 already has mechanisms for this type of hand-off built in and I see that getting implemented before this.
  16. Let's just say there's going to be technical issues getting an IP stream to hand-off between a wifi network and a wireless carrier. The best solution would be for the application to prebuffer the stream and reconnect before the buffer is empty.. Or just turn off your wifi before you start the stream.
  17. Good, if technical explanation of why Ec/Io determines which tower you use. http://www.telecomha...o-and-ebno.aspx
  18. I am afraid the Austin part of the Austin market may not go live until July or August. I'll be happy if they just turn on EVDO on the NV equipment so we can see consistent speeds close to 1Mb.
  19. Closest towers to me scheduled for upgrade this month. I'll get after photos after they are marked as finished. AU13XC058 AU13XC057 AU13XC063 Album: http://imgur.com/a/ei7bK#8
  20. I wonder if a custom rom running on a VZW phone would show lat lon? I think when I had my VZW GNEX running a rooted rom it showed lat and lon in netmonitor and cdma field test but i have horrible memory.
  21. I use cellmapper to find locations of towers not broadcasting correct lat and lon. You can set the app to upload your signal data and the site uses this crowd sourced data to compute tower locations and map out the sectors. It takes a bit of driving around but the more data you upload the better the maps get. You can look at the maps of Austin I've been updating as an example. Set Country to 310 and provider to 120. http://www.cellmapper.net/map.php
  22. And that's 5hp per sticker!
