Seems LTE is generating all the Network vision excitement, but what I am curious about is 800mhz CDMA.... At what point in the Network Vision upgrade process does 800mhz CDMA become live? Also.... From my experience 3.5 miles is about the max for a usable 1900 mhz CDMA signal. What is the average real world usable distance for 800 mhz CDMA?

IBEZ will be solved SOONER, rather than later. Which is a good thing. I would have liked for SoftBank to join the fight, because EVERYONE knows that their roaming rates are going to be abysmal with Sprint customers traveling to Mexico. Is this a raw deal?

With the extremely fast ramp-up of band 26 deployment in the recent months, a lot of the US is now covered by it. Some markets have been optimized, some haven't. For those markets that have seen band 26 optimization, what's your story? Did you used to get a weak 3G connection indoors, and now enjoy a usable 1-2 bar LTE connection? Is your 800Mhz LTE connection stronger, the same, or slightly weaker than 3G now? Let's try to keep this focused only on stories about areas that have seen a definite coverage improvement as a result of a fully optimized band 26 LTE deployment, not a thread that focuses on where optimization hasn't taken place yet. Perhaps we can boost morale and give us non-optimized folks something to look forward to. :-)

I'm James from OpenSignal. We're trying to map international rollout of LTE, but very few phones can report the band and bandwidth used, so we're hoping people can help us by firing up field test mode and submitting the data to our map - all the data can be downloaded. We've already got a great map of South Korea and China, there's a lot of 10 MHz and 20 MHz bands there, which explains why they're clocking some of the fastest LTE speeds on the planet. You actually need to use "service mode" on Android to do this: Type *#0011# Into a dialer. You should see Here you can read the LTE stats easily. The Band is 7 (around 2600 MHz), and the LTE Bandwidth for download (LTE DL BW) is 15 MHz. Actually the Earfcn_dl gives a more precise reading of the band, 2825, so if this available use this. You can fill in the form here: Google docs form Your data will appear on a map here: LTE bandwidth map. This won't work for all Android phones, I'm yet to find any other codes that can bring up this info (field test modes & service modes are implemented differently on different devices. On iOS try: *3001#12345#*[/size] Btw if any admin has the permissions, you can embed the form and map right here: Form: If that works fill out this form and your information will be automatically mapped: Loading… All the information is public, and responses are mapped immediately below – you will probably need to refresh this page before your data becomes visible. If it doesn’t appear after that there may be a problem geocoding please email me James (@ opensignal.com) with your observation and we’ll get it up. Map of LTE bandwidth.

So, I am posting a suggestion as to maybe scheduling some times to get together in, "The Lounge" to discuss certain topics. I'm an amateur radio operator and we call these over the radio "Nets" You have one person as the control operator for the discussion, and each person takes their turn to discuss. (It doesn't have to be this controlled). But throw out a topic (Related to Topics within S4GRU) And we all get together at that time and discuss. We can have several topics to discuss through out the week. I know alot of us are on daily. Think It would be a cool idea. If anyone is interested, I can throw something together and present it to the admin/staff. Thoughts? Kris

OK, so I was bored on a Sunday afternoon and started lookin around the various places I visit when I have vacation time. One of these places is my home town in South East Texas. I remember way back when, circa 1997, Sprint came to town via UsUnwired. It was great if you were in Beaumont but anytime you went north to the lakes after Silsbee you were roaming. My uncle had a Nextel phone from about 1999-2007 and I remember he never would lose that coverage until Jasper. Today, I found that the highway north outta Beaumont had iDEN towers, while Sprint never built any antenna/towers/cells along that same route; even after the Merger in 2005, this area since then has remained as it was. So, fast forward to today. I've lurked and read, thought it through, and concluded the following. The iDEN towers in this area are not being "pruned" at this time do to no overlapping coverage. These iDEN towers will be decommissioned sometime between now and 2013 Since these towers do not co-locate any former UsUnwired or Sprint CDMA equipment, upon such decommissioning, there well be a resounding null of native Sprint coverage in this area. For the few area's where there are some overlaps, such as Silsbee and Lumberton, where iDEN equipment is on one tower and seperated by anywhere from 0.25 - 1.5 miles, Network Vision will only be implemented on the Sprint CDMA towers. For the areas that had Nextel iDEN service, they will not be receiving new CDMA Sprint service, even when 1xAdvanced is deployed in the EMSR band vacated by Nextel iDEN Would these conclusions be valid? Is there any hope for those areas where there is Nextel/iDEN but no Sprint/CDMA that they will not be left behind. I know this area I am referencing may be small, but what of the iDEN customers when decommission happens; as there would be no CDMA coverage, they would not be able to get Sprint DC, so does Sprint just say: "Sorry, you're SOL?" Here is a little map i spent 20-30min putting together from Sprint's website; I know its a little "cut-and-paste" like, but the information necessary is available to see.

So now that iDen is shutdown, when can we expect a 800mhz rollout? From my understanding, the equipment is capable and it is as simple as a software upgrade. Is this something that involves a technician visiting the site? Thanks in advance.
