  1. What LUCK! I've been following this site to keep up w/ the LTE rollout. I got my first taste several months ago (quite literally, just enough to run a few tests to convince myself it was real!) in Baltimore on my way back from Philly. I ventured out when Alexandria started showing up on Sensorly and I mapped a few points off Eisenhower Ave. I've also done my best to add some extra points out in Front Royal on the Shentel side of things when I go to Shenandoah NP. However this weekend's newest LTE blossom in the I66/US50/123 area of Fairfax is almost to good to be true. 1st... I live along side I66 and in a sort of "bowled out" area of land so I never got WiMAX at my house (yard, indoors, upstairs, anywhere). The signal would literally drop the second I went up my drive. Likewise, my EvDO service was marginal (1-2 GNex "bars") but generally provided adequate voice coverage and data when I ventured out of WiFi range.

     

    FAST FORWARD to last night

     

    I get home, I was having software-related connectivity issues w/ eHRPD (could "see" CDMA and/or 4G but wouldn;t handoff), only forcing EvDO sans-eHRPD/LTE would enable me to aquire data connectivity. After a reflash of my rom I was able to aquire an LTE signal in my yard... and most surprisingly in my house as well!!! I do seem to notice a very modest increase in my CDMA signal strength too but that could just be placebo. Anyways... I went from marginal 3G and no LTE or WiMAX to useable LTE even indoors and that's with just one nearby site complete and LTE-enabled... Network Vision is going to be awesome!!!!!

     

    That's awesome! I have an almost okay signal at my house, and I'm hoping for an upgrade to LTE any day now, seeing as I can get it a couple hundred feet away. Stick, NV has been great to me, I can actually stream things now if I'm connected to the right tower.

  2. I'll try as best I can, but I am definitely one of the less knowledgable people here. Here goes nothing.

    3G and 4G are overarching terms for third generation (3G) and fourth generation (4G) wireless data transmission technologies. There are certain speed and latency standards that must be met for something to qualify as "4G." CDMA (Code Division Multiple Access) and GSM (Global System for Mobile communications) are two different branches of cellular access. I don't know how they actually work and differ, sorry, but Sprint and Verizon use CDMA and AT&T and T-Mobile use GSM.

    LTE (Long Term Evolution) is the real 4G, and is the only 4G technology truly certified as such. However....

    WiMax came along and it was so much faster than regular old CDMA that Sprint decided to call it "4G." However, this sort of ruined everything in terms of naming schemes. WiMax was technically not 4G, but Sprint called it that, so whatever.

    HSPA and HSPA+ (Evolved High Speed Packet Access) are 3G technologies citation needed, however they are significantly faster than regular old 3G, so AT&T decided to call it 4G just as Sprint had with WiMax.

    When LTE came along with Verizon, there was a conflict between Faux-G (Punny, eh?) and real 4G, LTE. So now we have 4G LTE, 4G, and 3G. It's not pretty.

    eHRPD (enhanced High Rate Packet Data) is just a handoff between 3G and LTE.

    The speeds go from LTE>>>HSPA+>>CDMA/GSM

    All of this information is in the FAQ: http://s4gru.com/index.php?/topic/1704-frequently-asked-questions/

    Hopefully my explanation of these things makes some sort of sense, and the FAQ is almost definitely more helpful and knowledgeable.

  3. Got a hit in Takoma Park, right next to New Hampshire avenue! I couldn't really figure out which tower was broadcasting it, as the best signal I got was about -105 dbm. Best speeds were close to 10 down and 6 up, although most were about 4-5/2-3. Still awesome though.

    I also mapped it on Sensorly, but it doesn't seem to be showing up. I'll try again tomorrow.

  4. I was in DC yesterday and noticed 4g becoming more alive on the edges of the city (Was going to see a friend in Silver Spring) but that darned METRO Shuttle Bus put a crimp in those plans wasn't worth it. I Megabused it back to Philadelphia, got a good portion of coverage on MD-295 not sure where it cut in but almost all the way to the Harbor Tunnel

    Yeah, I'm constantly hoping for that little 4G to pop up. Good to know that it's expanding in this manner. This weekend, I should be around DC again so hopefully I can check how far the 4G extends. Where in SS were you going?

  5. They will add more CDMA 800 soon. They expedited the iDEN channel clearing in some places because of FIT's and call drop problems (ala Chicago). DC and Baltimore have CDMA 800 being deployed now in many places. And this is probably because iDEN is already cleared off Channel 476 in that area. Sprint may have more areas add CDMA 800 now if they get into a pinch. Otherwise, they will probably just wait until July 1st to start turning them on a larger scale.

    That's good to hear. Does it specify in sponsor maps whether a site is broadcasting 800?

  6. Well, I was at the REI in college park for the attic sale today and I didn't see any 4G pop up. I forgot to map with sensorly, but I doubt I would've seen anything. I'm going into DC later, so I'll map and speedtest that trip. Although my phone is still reading the 3G upload speeds wrong.

     

    Sorry guys, there might be LTE there, my phone was in CDMA only mode. Found this out when I wasn't picking up even eHRPD in DC or on my home tower.

  7. Well, I was at the REI in college park for the attic sale today and I didn't see any 4G pop up. I forgot to map with sensorly, but I doubt I would've seen anything. I'm going into DC later, so I'll map and speedtest that trip. Although my phone is still reading the 3G upload speeds wrong.

  8. Looks like you hooked into The Prez's direct line to the Kremlin, or you are in 2030 and warped back to S4gru

    The weird thing is that it has continued, with varying speeds. So I'm hoping that speedtest is bugged out because of upgrades....wishful thinking :) Down at the bottom you could see more normal tests.

  9. I will try to check that tower in Langley Park, if someone could go give me the coordinates, I might be able to go check it out tomorrow (hopefully). Also, I'll be around downtown Silver Spring and Rockville tomorrow, and DC the next day, so I'll map Sensorly on those trips and hopefully pick up something! Glad to see this thread is off to a good start too!

  10.  

    Yeah, I believe I saw the same speed test. And that led me to conjecture that the Nexus 4 could be gimped by no MIMO, as that would limit it to roughly 18 Mbps downlink throughput on a 5 MHz FDD carrier.

     

    But none other than Howard Chui himself, of HowardForums fame, has demonstrated undeniably MIMO enhanced Nexus 4 LTE throughput:

    Wow. That's all I can say to those speeds, especially on an "unsupported" device

  11. Well, I'm definitely feeling the NV upgrades, as I was able to stream Netflix on my phone while in the car, and I've been getting extremely consistent 1.5/1.0 speed tests. I'll be in the heart of DC on thanksgiving, so I might just have to talk a little sensorly walkabout hunting for LTE.

  12. S3, if u can find one for a decent price off eBay/Craigslist... It's 3G and LTE radios work just fine for me and I'm not in the best 3G area at times but speeds still seem fine. I feel like I'm on a whole new network using the S3, but this is only my experience with it s far.

     

    This is actually exactly how I feel about the S3. It was testing the same, but felt so much better.
