  3. I definitely saw Chicago being one of the first TD-LTE markets. It's a spectrum constrained market for Sprint. I bet Sprint made it clear it wanted Chicago first. Chicago is forecasted to be one of the first markets maxing out its new 5x5 LTE 1900 carriers. And it doesnt have much for options for additional LTE carriers in 1900. Sprint is counting on Clearwire in Chicago for the long term. Robert via NOVO7PALADIN Tablet using Forum Runner
  4. S4GRU is an unregistered not for profit site. It would be easier for us to become a commercial site than to register as a non-profit organization. It's not worth the bureaucratic red tape. Also, as a non-profit, some of our required filings would show source names. And I could never do that. Since S4GRU is not a business with a profit incentive, and I'm just a guy, we will not be making this thing much more elaborate than it is now. I just don't have the resources. But I thank you all who have contributed and would like to contribute. PayPal donations are what pays our costs and keeps the site live. Robert via NOVO7PALADIN Tablet using Forum Runner
  5. You would think a city wide WiFi system like this would cause a lot of interference issues for other WiFi systems and would render the channels being broadcast virtually useless to any other WiFi router in the city. That would probably be fine, if it was limited to only one company in one market in one 20MHz channel. However, if more than one were to ever set up, or go with a 40MHz WiFi setup, it could be complete chaos. Cable cos better be respectful of this unlicensed spectrum, or it may cause the FCC to crack down on 2.4GHz spectrum usage. Just thinking out loud. I do really like the idea. Just hope it's really thought through to be a good neighbor. Robert via NOVO7PALADIN Tablet using Forum Runner

  8. The Ericsson contract wouldn't give them the ability to upgrade T1 service to AAV for Sprint on their own, just based on performance. Ericsson can make the recommendation to Sprint and prepare a change order request to do the work. But most likely Sprint would reject that since Network Vision work is forthcoming. Robert
  9. You know...the one area where I saw the one year lead time was CenturyLink in the Central Illinois market!!! Robert
  10. Only Premier Sponsors, S4GRU Writers, Moderators and Administrators can save files/pics to our servers. We are limited in the amount of server space we have, so we are chintzy in who gets to save files. You can use third party places to save attachments. Even Tapatalk and Forum Runner will allow you to save files to their servers to feature on S4GRU. Heck, I even sometimes will use Facebook and Google+ to host them, harvest the URL, and post here.

  11. It is going to be an issue for early LTE device adopters in many WiMax markets. Someone in a WiMax market who uses it regularly, should probably wait to upgrade until NV is well under way in their area. Robert

  13. Welcome to S4GRU! LA Metro market is already under way. You can see a screen shot below of the map showing the sites that are already live. S4GRU Sponsors have access to this map and many others. Sponsors can click on the map, zoom in and pan around, all over the country. There are currently already 500 Network Vision sites live around the country on these maps. More added every few days. Thank you for the compliments. I hope to see you around some more in the future.

  14. I have asked all my sources this question, and most glaze over. However, I did have one Samsung RF Engineer tell me that they are configuring all 1xA carriers differently based on location. Urban sites will be deployed for capacity gains. Rural sites will be deployed for coverage gain. So there will be a lot of variability. We have detailed information about the deployment of every single Sprint site in the country. I wish it also contained 1xA configuration info. Robert
  15. Thank you for agreeing with me. This is what I said right above your comment. However, my chief point stands that the comment made will mislead many into believing that double the coverage gain comes from 1900 CDMA alone, when in reality that coverage gain stated is the difference between legacy 1900 and NV 800. That's what we do here at S4GRU, clarify and inform. Much better than Sprint does, I might add. Robert
  16. The problem with the temporary T1 fixes, from what I have seen, is this: Site has insufficient backhaul for data demands in the cell and throughput speeds start dropping. As speeds start dropping, usage also starts to go down. As speeds start to drop below 100kbps, all streaming activity stops. Users actually modify their behavior and stop using data so much because the experience is so poor. However, they keep using it enough that the experience remains poor and does not improve. When this occurs, Sprint's network manager (Ericsson) orders additional T1 lines for the site. Usually one or two more. It takes between 3 months and one year for them to get set at the site and punched down for use. Yes, that's right. Sometimes it takes a full year! Once the T1's are punched down, Ericsson comes back out and connects the new T1 lines (and sometimes adds carriers too). Once the additional T1 backhaul is live, speeds shoot right up. 0.9Mbps to 1.4Mbps, on average. Sprint customers start to notice something is different within a few days. People start running speed tests. People start opening their minds to the possibilities of using their 3G data again at the site. People start using their Pandora again. People start streaming Netflix again. And within a few weeks, or a few months, the site is back down in the dumps again. I have seen this pattern happen over and over again. Better performance = more usage, in an unlimited usage network. However, not all of these speed upgrades being implemented are T1. Some are AAV. On those sites that are getting 2Mbps+ EVDO speeds, the backhaul in those places is AAV and not T1. These sites seem to be much less affected a few weeks and months down the road. Even though T1's are 'right-sized' for EVDO carrier backhaul, modern usage at dense cells just don't provide the performance needed. For Sprint to add more than one or two additional T1's is cost prohibitive. T1's are expensive creatures. The answer, of course, is enhanced backhaul. Like what's being offered in Network Vision. Almost all sites will be going to Microwave or AAV backhaul. Much more scalable ethernet based backhaul solutions. Sprint is getting closer and closer every day to abandoning their old archaic (and expensive) T1 backed backhaul. And I say good riddance! Robert
  17. My comments are not based on guesses. They are based on reports from Sprint's FIT's. The gains are approximately 20% in field testing from legacy to NV on 1900 CDMA. And from our members who have used NV sites, this seems to be substantiated. There are no wonderful sudden gains in coverage occurring. Due to downtilt at most sites, the gains will not be in coverage area, but in stronger signal. Only at sites at the periphery of existing coverages (rural areas) can you adjust the downtilit up to try to capture the 20% coverage gain. Robert - Posted from my E4GT with ICS using Forum Runner
  18. This is slightly misleading. They may be seeing a coverage doubling on NV 800 CDMA compared to legacy 1900 CDMA. Since they are not deploying EVDO on 800, this is 1x only. However, they are not seeing those kinds of gains between NV 1900 CDMA and legacy 1900 CDMA. That gain is not 100%, it is approximately 20% gain between the two.
