  1. The Moto X does not support 800 or 2500 LTE The iPhone 5s supports 800mhz LTE Verizon will not be shutting down its CDMA network for at least 7 years (2021 I believe) however Sprints new plans only allow 100mb of data roaming where it used to be 300mb. Sprint will add Volte to its network in the next few years but that doesnt mean it will roam with VZW's network although it may roam on some regional carriers networks like US Cellular in the future.
  2. Im hopeful SMR will change things. Because the SMR lte network wont play with cdma it doesnt have to be turned on in clusters ericcson will upgrade the existing g-block lte sites without as much hesitation.
  3. My sister hates sprint because of these sites remaining 3G only (with legacy backhaul). Their service has become unusable in the area. I hope things improve.
  4. The Glenpool site has legacy equipment removed and has for a while. Its still 3G only though.
  5. If macpcs doesnt get it before me I'll get it in a few days.
  6. Perhaps they're gearing up for VoLTE and skipping cdma hd voice much like they skipped dual band handsets for triband (except the new iPhones of course).
  7. I would love to tell you that it absolutely will make an impact in Tulsa but Ericcson's reluctance to touch the SMR 800mhz band even for cdma voice and the fact that tulsa never was an official wimax market. I couldnt tell you. I would think that a year from now they will at least start adding 2500 to our Sprint only sites but I could be wrong.
  8. I for one would like to see an engineering screen from the area you were in. It looks like your phone/ROM would support it.
  9. That Signalcheck app screenshot looks interesting. Do you have a shot of what it looks like normally (native Sprint LTE)?
  10. Sometimes the frequency doesnt matter if the sites are closer. In my area AT&T has 850mhz spectrum as does US Cellular. Verizon only has 1900 for voice. I have a US Cellular device but many times I roam onto Verizon when I go into a metal building at work. This is because there is a verizon site less than half a mile from my workplace where others are much further away. With the right site density a 1900mhz network can have better coverage than a more spaced out 850mhz network.
  11. You could take over an old verizon unlimited plan. They have unlimited tethering available with it.
  12. I know this is a Sprint site but I figured you all would appreciate this, I was playing with my USCC Galaxy S4 and found a menu to manually select LTE band classes. I toggled Band 5. Lo and behold! LTE Band 5 (Cellular 850) is live in Tulsa for US Cellular! This band class is compatible with band 26 which new triband devices and the iPhone 5s/5c support.
  13. I think any LTE roaming agreements will be shown and billed as native. It is far more in the interest of smaller carriers to use Sprints network for nationwide coverage than for Sprint users to get better coverage. If anyone could gouge on pricing it would be Sprint but based on Hesse's comments about reducing roaming fees I suspect the goal is fair reciprocity. Sent from my Galaxy using Tapatalk 2
  14. For all the Apple folks, I would just be happy you got band 26. Coverage issues are the biggest problem with Sprint's LTE network for now and band 26 solves that problem. Capacity will only become an issue after you've upgraded to your next iPhone which will (probably) support band 41 with a built out network at that time.
  15. TlDR Sprint is TDD and that carrier is FDD. Even though they sound similar (20mHz FDD and 20mHz TDD), the reality is that the FDD carrier actually is using twice the spectrum but TDD makes up for it partially by being able to allocate more of its spectrum to uploading. 20mHz FDD 20mHz Downlink spectrum 20mHz Uplink Spectrum 20mHz TDD 20mhz Downlink/Uplink For Sprint's 3:2 DL to UL ratio 12mHz Downlink 8mHz Uplink
  16. For a 2x2 MIMO LTE airlink Downlink Peak speed = 7.5 Mbps/Hz * Downlink bandwidth So for a 20mhz FDD link you have 20mhz downlink spectrum and 20mHz uplink or 20+20 MHz = 40mHz of total spectrum For download speeds we only care about the downlink bandwidth (20mHz in this case) So peak download speed = 20mHz * 7.5mbps/MHz = 150mbps For TDD air links a single chunk of spectrum is used for upload and download. The connection is separated by time division. There is a time allocated to upload and a time to download. This doesn't have to be symmetric either. In Sprint's case they have a 3:2 download to upload ratio which means that 3/5 = 60% of the time the airlink is in a downlink state for your device. To calculate the peak downlink speed of a TDD air link take the ratio (3 downlink to 2 uplink) add the two factors together to get 5. Next divide the downlink by the total time ( 3 / 5 = 0.60 = 60%). This is your downlink percentage that I described earlier. Now take your TDD bandwidth (for Sprint 20mHZ) multiply it by your percentage and you get you downlink bandwidth (0.6 * 20mHz = 12 MHz). Finally multiply your downlink bandwidth by the standard LTE peak spectral efficiency of 7.5mbps/MHz So.. Max DL Speed = 20mHz TDD bandwidth * (0.60 DL percentage) * 7.5 Mbps/MHz = 90mbps For carrier aggregation multiply your airlink speeds by the number of channels. So for 2 aggregated 20mHz TDD channels the max speed is 2 channels * 90mbps/channel = 180mbps Or for 20mHz FDD 2 channels * 150mbps/channel = 300mbps

    I really like the new Sony phones and the direction they've gone with making their high-end devices water resistant. Its a damn shame Sprint doesn't carry sony products. I think its at least partly (more likely mostly) because Sony won't make a CDMA handset though.
  18. The former clearwire contractors are converting WiMax sites at a reasonable pace in WiMax markets. New TDD coverage on NV sites won't happen for a while. Remember all the planning and permitting that it took to start Network Vision? That has to happen again for TDD on non-wimax sites.
