Network Vision/LTE - Chicago Market

Recommended Posts

You probably share this same sentiment, but why would Sprint put any sort of additional or immediate efforts into an area such as dekalb with such a smaller population than the other areas undergoing NV upgrades around Chicago. We have to be honest, most companies and governments just go where the money is, in this case Sprint Subscribers, if there are 5K sprint subscribers in Dekalb and 25K in Schaumburg then of course they are going to pay more attention to Schaumburg and getting those customers the upgrades first. Plus, it might also be easier b/c in a denser environment they can make a few upgrades and reach more people, in Dekalb its so rural they have to make upgrades across dozens of miles to cover the 5K people with proper service. It sounds like a bad experience, but its not a surprise to me to hear that a rural area with fewer customers and demands is last on the list.

Places like Harvard and Woodstock now have LTE. Parts of Chicago don't. One of the common themes of this whole forum has been, "it ain't where there are the most people, it's where the infrastructure and permits are ready." Dekalb, because of NIU, has a very dense population. If you look at the sites completed map, the random distribution of red "3G only" pins doesn't seem to follow population density.

You apparently underestimate the size and data-hunger in the DeKalb\Sycamore area. Hah, people in the suburbs always make me laugh. Think they're the center of the earth when in reality, they haven't got a clue about anything outside of their pompous bubble.

 

I'd venture to say that there are 75k people in the area serviced by the DeKalb\Sycamore towers. There are 25k college kids here, so young data-hungry people where everyone has a cell phone. Given the univeristy, I'd venture to say that we are *MORE* dense than anywhere in Schaumburg, given larger lot sizes and no student dorms and large off-campus apartment buildings.

 

Given the likely higher density in DeKalb and definitely a larger percentage of data-hungry customers along with my travels throughout the suburbs, I can assure you that the data network in DeKalb was in need of an upgrade far more than most places in Chicagoland. Of course I am excepting the loop and anywhere there is a large event such as a Cubs game. It was just as bad as DeKalb.

 

When I have more time later, I'll see if I can calculate some density information for you, both people and towers.

 

 

Oh, and also...  the equipment has been in place for several months, some perhaps even a year. It just isn't turned on yet.

I only through Schaumburg out there arbitrarily as a common and well known suburb.  I dont live or work in the burbs, I live and work in the city and loop.  The Loop network is awful too, before some of the 4G hit, it was timeout after timeout and 3G only.  But again, if you know this about the Dekalb/Sycamore area, then I can't imagine Sprint doesn't know its own load factors.  How could they have not made something so dense, data hungry, and in need (being that its in disarray as u describe) not a priority then?

I don't know, nor does S4GRU (forgot his name). The gear has been in place, so permitting wouldn't be an issue. The network often times out or is otherwise terrible (I've had speed tests under 7 kilobits and over 3,900 ms) within 1.5 miles of the tower. Where they've turned up the backhaul, it's better, where they've turned on LTE, it's great.

 

There's no shortage of backhaul providers in DeKalb\Sycamore. Windstream is all over as is DFO (actually, Windstream rides DFO in a lot of areas around here). Comcast and Frontier have fiber all over. Frontier got AT&T's fiber turned up fairly quickly from when permit applications were submitted. CenturyLink has some fiber as well. If it was that bad with a backhaul vendor, they could have switched to another one. I'd have been more than glad to supply the backhaul in this area as well (and have the technical ability to). They have made extensive use of microwave around here, so they could have built their own microwave to an area where they weren't having whatever issues they have been having.

Hey I have some questions and trying to find some word on things but 117 page threads like this are exactly "user-friendly" and make it really hard to find the info i'm looking for so I apologize if this is addressed elsewhere.

 

I have a Sprint iPhone 5 and I live in the Lakeview / Wrigleyville  / Southport area and I find my LTE coverage to be a joke. It will be blazing fast one block and then awful the next, full bars LTE in one area but nothing actually loads, switch to Airplane mode, switch back and it will show 3G instead of LTE and suddenly things work again. You get the picture.  Things were actually better / faster in December and January as the Network Vision stuff I read about on here were starting to roll out, but since then it seems to have gotten worse. I get dropped calls and missed calls in my own apartment which was previously fine. 

 

I know it's not the specific device because I've had it replaced for other reasons and my other Sprint friends are experiencing the same in my area, I find the same through much of the city as well (especially commuting home on the Brown line).

 

Long story short... I'm wondering if this has to do with this 800 / 1900 thing you guys talk about, can I expect this Nextel shutdown or US Cellular thing to make a difference at anytime soon? Is Network Vision done being rolled out in my area?

 

Basically... your entire thread is TLDR, please assume I'm a moron (but please don't treat me like one) and can someone please inform me what I can expect in the near term, long term, or point me to an easy resource to find out? I'm considering leaving Sprint when the next iPhone comes out if I don't see some signs of hope and I really don't want to.

 

Also, with all due respect. Please don't tell me to switch to Android. I'm a former Apple employee of 6+ years and I'm not interested, I'd sooner leave my carrier than leave iOS. 

 

Thanks and I'm sorry if this isn't the right place to post this!

 

Cheers.

Honestly I have good LTE around Lakeview and Jefferson park area. Maybe the towers was getting worked on like around the Austin area recently.

I don't know.  I can only repeat the sentiment I have taken away from being on this board since it started.  That is forget whatever time frames Sprint or the Mods throw out there.  There are always hiccups, always slow downs, always new pieces of the NV process just around the corner that will make things better.  Its going to take time, time that I would say will last well into 2014.  True most of the tower upgrades came through the region within the last 12 months, though if you have read this forum you will see the Loop is just now getting their tower upgrades.  But given all the gripe about backhaul delays in NW Indiana, Dekalb, Lake County......all the gripe about Sprint coming back to actually tweek the tilt on the 4G panels at "a later date".........all the gripe about the slow progression of NV in the loop given assumed permitting issues.........all the gripe about now having to wait even longer to get the 800 Mhz spectrum usable by devices.........all the gripe about when will we actually see additional capacity from the US Cellular acquisition, etc etc.  Its rather obvious isn't it, Sprint's network is in massive flux and its going to take years still before its matured to the level of consistent and widespread high performance, both locally and across the nation.

This is in general how I'm feeling and it seems to me that by the time this is all settled down whatever the new hotness in data speeds/connection next will be on the way / rolled out by AT&T and Verizon before Sprint gets it's stuff together on last year's tech.

 

Specifically right now, is there a good place I could learn about this 800 / 1900 thing and estimated road maps? Because it sounds like this is the issue in my area with an iPhone. Is there a thread I'm missing or do I just need to kinda hang out on these forums all the time to find anything out?

 

Thanks for the replies.

The only reason I am with Sprint is b/c its cheaper and the data is unlimited.  The last thing I want to do is fretting about overages and data limits and thresholds and such.  So its not b/c I feel the network is more robust or advanced, even though most say Chicago has the most built out NV, as far as I can tell ATT and Verizon still have more LTE in more places.  Sprint's is also 10x as sensitive to signal strength and being indoors/outdoors.  I can't tell you time and time again how I can put my phone with full LTE right next to a verizon phone with full LTE, walk inside Target, Grocery Store, United Center, a Bar, the Subway, etc.....and Sprint is by far the quickest to drop out of LTE and go right back to low bar 3G.  The Verizon and ATT's always hold their LTE signal much longer indoors in my experiences.

That's only because of the frequency sprint uses. Att and vzw operate in the lower 700. Which doesn't cover as much but penertrates buildings excellently. Sprint uses 1900 which covers more areas but doesn't penertrate as well as vzw or att

Yeah I know this, I'm just saying we should all have the correct expectations.  Until well after Sprint has a working 800 Mhz LTE where we all have phones that support this as well, the LTE we have from Sprint now is much weaker (signal hold wise) than ATT and Verizon.  Just know what you are getting is my point.

800 MHz voice is already rolling out to NV areas.

 

I'm not sure who will be deploying LTE-TDD or LTE-Advanced first.

AT&T has about as much coverage as Sprint, but they started much earlier. I wouldn't be surprised if Sprint passed them.

We would all hope they do the smart thing and go for the money, honestly 75-90% of Sprint subscribers could care less about whether there is any reception in rural areas (roaming phone calls only would make it a non-issue even on an advertising map) and if the interstates were covered (which is really what many/most customers who go rural on rare occasions are worried about) its easily 90%+. My brother is in Hoffman Estates toward ex-urb Elgin so I can understand why Sprints capital investment is better spent closer in than out there.

 

Now if Sprint do something about all the dropped calls with NV nearing completion in the mid burbs into the city (Darien/Elmhurst/city of chicago, all even on the interstates) lots of customers would appreciate that..

The tower at Sheridan and Lake Shore must have gone 800, because my phone won't connect to my airave anymore :-(...got a letter in the mail saying that the support for airave 1.0 was ending Aug 1, so I called and apparently they'll send me a current generation airave so not all bad.

Sprint is likely to get TDD-LTE first but I am not sure about LTE Advanced. AT&T is playing with numbers to make their network seem large when in truth, Sprint's coverage is roughly the same in terms of pure square mileage, but the density is not as great yet.

You're most likely connected to the tower by the Hospital and Hyvee. That tower has been active for about a week.

Now that markets like Chicago are nearing ubiquitous coverage the transition into Lte advanced with 800SMR will give Sprint equal playing fields with the duopoly for indoor network coverage. Obviously 5x5 speeds are not as "fast" but this is just as large a decision based on capacity needs; of which Sprint's effective network load is under 1/2 of either AT&T or Verizon.  Literally this is right around the corner for you guys Chicago is one of the first areas to see an 800 MHZ signal from Sprint and come this fall when SMR capable smartphones roll out you will be among the first to experience it first hand.

I work next door to you.  I have Galaxy S3 and my LTE has been blazing since the tower on Congress and Financial Place got LTE a couple weeks ago (finally).  I haven't noticed a 3G absence.  Do a PRL update.  If it doesn't work, Sprint Tech support is where you need to go.

Thanks I've done a prl update about six times today with no difference. But as soon as I go outside I get data again, Was never like that before, wondering if the upgrades make 3G not be able to penetrate the building as well. Hopefully only temporary

I work at the Sears Tower and often find that I'll have a great LTE signal (sub 90 RSRP) while outside, especially near the Quincy El stop but my internet won't work at all or will be painfully slow (sub 100kbps).  When I'm out much later at night though I'll get much better speeds and very usable internet (5-10mbps).  Is this a sign of the network already being saturated?  If I have that strong of an LTE signal confirmed in the engineering screen but still getting such poor speeds could it be anything other than network saturation?

There are several sites around the loop that seem to have incredibly slow or completely unusable speeds even with a very strong LTE signal. Once I move around enough to connect to a different tower, the problem disappears. This has gone on for weeks with whatever tower covers State and Jackson for example...you'd think they'd be aware of the problem by now...

      I recently went on an 8 day cruise from NYC to the Caribbean that stopped in Turks and Caicos, Puerto Rico, and the Dominican Republic. My first stop was Grand Turk and there I opted for the free roaming. My S9+ automatically connected to Flow's (Cable & Wireless) LTE network where I received speeds of around 120kbps on average with boosts of up to 150kbps. Something worth noting is that on speed tests, the server prefers to default to Sprint's Miami server as opposed to local servers. Speeds were more than adequate for any amount of web browsing and honestly felt much faster than in reality. It helps that using Chrome will save you data by not loading pictures on certain sites unless you click them.
      In Puerto Rico, I connected to Band 13 on the way into the port in San Juan but once I was in the city, my phone never left Band 41. While the phone was usable, speeds remained significantly lower than what I've come to expect from 3xCA in the mainland U.S. Data speeds peaked at around 25-30Mbos but on average were in the 5-10 Mbps range even on LTE+. Signal remained strong everywhere though. 
      Finally in the Dominican Republic, I entered in Amber Cover which is in Puerto Plata. My phone latched onto a weak Band 2 LTE signal in the port from Altice (called Orange Dominicana in SignalCheck). I had trouble loading pages though. Once off of the ship and out in the open, I had a much stronger signal which allowed me to browse the internet without a hitch. Because it was the last day of my trip, while at the beach I decided to purchase the 24 hour high speed pass for $5. My speeds went from 120kbps to 65Mbps in less than 5 seconds. In some areas speeds were slower, particularly at the port where it struggled to break 2Mbps. Now, back on the boat my phone is flipping between weak Band 4 LTE and overloaded Band 5 HSPA+ from Claro (called Verizon Dominicana in SignalCheck Pro). Here is the difference in speed from before and after purchasing the high speed pass.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      Sprint 4G Rollout Updates
      Monday, June 25, 2012 - 4:27 PM MDT
       
      As technologies advance, the equipment to use the technology must advance as well. With the upcoming release of 4G LTE in our area (Houston), new equipment will be required to be able to use it. Although Sprint will have numerous data devices to handle the usage by the end of the year, only the Sprint Tri-Band Modem will be available at the rollout of the 4G LTE service.
      Due to the enormous dependence my business has on accessing data in a mobile environment, plus the great increases in data speed available with 4G LTE, this makes getting access to 4G LTE imperative to me. I depended heavily on the Sierra Wireless data devices when I started this business 7 years ago for my source of a reliable method of mobile data transmission. This relationship continued on until the release of the original Hotspot with the 4G service in my area.
      At one point, I was so displeased with past models, that I had sworn I would never buy another Sierra Wireless device as long as I live. This conclusion was reached after having numerous issues with previous hotspot models. There were so many problems that it seemed as if the device was never even tested on the networks it was to be used on. Also Sprint actively blocked reviews of the device, likely to not hinder sales in spite of the problems.
      My need for a new device with both WiMax and LTE capability outweighed my outright dislike of Sierra Wireless products. I proceeded against better judgment, and the Tri-Band modem was ordered even though the possibility of getting a substandard unit once again was always at the forefront of my mind.
       
      On with the show
       

      The official part number of the Tri-Band Modem is 803S. Along with the modem, I also ordered the SSX7077-V desktop cradle. I had to dig through a lot sites to find the information necessary to make this decision for my business. Much to my surprise, even though I was told the cradle was not available yet, I got a Sprint telesales person who was able to use the part number and find they had it in stock.
      Upon arrival I unpacked the unit and cradle...while holding my breath. The device that came out of the box was a pleasant departure from the previous Hotspots I had owned. Above is a picture of the device as it was shipped with all components. There was a small user guide as well but to get the real instructions the user guide must be downloaded from Sprint.
       
      Gone was the one piece blow molded plastic case which allowed no air circulation and caused the prior Hotspots to overheat quickly. Although the display is still too small for my aging eyes (it is actually the same display size as prior units) the change to the case makes it much easier to see in the interior of my van where the device will mostly be used.
      In this picture of the front you can see that there is a new button arrangement as compared to the older Hotspots. Also in the picture is the USB cable for use with the charger or to connect a computer, the AC to USB adapter, the battery and the battery cover. I opened the cradle, which was surprisingly inexpensive, and was delighted to find an additional AC to USB adapter which meant the cradle could be left in place without having to move the adapter around.
      As you look at the modem from the side you can see the antenna ports (the covers are open), the USB connector in the middle and the slot for the memory card. The round hole just right of the left antenna port is the reset button for the unit.

      Here is the same view with the battery and cover installed. Notice that the SD card slot is covered by the
      battery cover.
       

      The opposite side has two switches. The one on the left is a WPS setup button while the one on the right is a slider to mute the unit.
       

       
      The unit sits nicely in the cradle and looks to me to be a solution to help keep the USB port for the charger/interface cable from failing. This has been a major issue with the prior Hotspots. The case of the unit also helps support the USB port to take some of the load off of the circuit board.
      It took quite a bit of digging on the Sierra Wireless site to find out that the antenna ports are for the 4G WiMax band only. The cradle contains 2 5dbi omnidirectional antennas to allow full use of the WiMax network architecture.
       
      Initial testing

      The initial testing of the unit looks promising. The antennas in the cradle for 4G WiMax actually seem to get 3 – 5dBm gain in all conditions tested. The new unit has the ability to search the other bands for signals while staying connected. This allows less downtime between band changes. I notice a lot less disruption when switching bands.
      This unit has better reception on 3G and 4G WiMax than the previous hotspots and even the U600 USB modem I use as well. 4G WiMax is able to connect quickly even at 10% and the cradle has improved stability of WiMax and decreased ping times. For a short time I had access to Sprint 4G LTE as they were testing the towers in my area. The speeds were incredilbly faster. A 10% 4G LTE signal averaged 8.12Mbps download and 1.85Mbps upload. An 80% signal was able to get 35.8Mbps down on my best test and 22.1Mbps up.
      The upload speeds was very unexpected, and much higher than Sprint LTE smartphone devices have reported. This is likely due to much stronger transmit capabilities of the hotspot. I also discovered that when the modem is tethered the cable limits the bandwidth to approximately 20Mbps total speed. It will be interesting to see how it works in the 12 to 14 hour days of hot Houston Weather.
       
      First week in the field
      The Tri Band Modem got pressed into service a little quicker than planned, as my main unit went down with a bad transmission and the U600 USB modem with a Cradlepoint that was in this unit appears to have been damaged by the wrecker’s radio which runs on the edge of the WiMax frequency at 5 watts. The units have been sent in to determine cause of failure and for repairs but I think next time I will make sure all electronics are powered off before getting that close to a transmitter (OUCH!!).
      I am running the same routes in a rental van with the Tri-Band Modem that I normally use the other units on. There is less downtime in the signal gaps I am familiar with and areas where I have had signal problems in both 3G and 4G WiMax are much improved. I have yet to encounter any more 4G LTE signals but am looking forward to the service coming online soon. The unit seems to be running hotter than I would like with a fully charged battery but is actually cooler that the previous Hotspots. The temperature is supposed to soar over the next few days without the cloudiness we have had this past week. So it will be interesting to see if the overheating problems of previous models still occur.
       
      Week 2 – The True test
      The unit is getting worked really hard this week with temperatures outside up near 100 degrees. The GPS is useless with this kind of sun load as the unit will overheat if left in direct sunlight (as the instructions state) in about 20 minutes. The good news is that this is about twice as long as my original Hotspot will last. How anyone can make a unit that requires a clear view of the sky for GPS but can’t handle sunlight is beyond comprehension. A quick check of the Tri-Band’s temperature specs shows that the unit is only rated for 95 degrees. The prior Hotspot was rated well above the century mark but couldn’t even handle 90 degrees for any length of time. The crappiest laptop on the market will handle 105 degrees plus all day long. The true test will be my afternoon calls when the temperatures are high. Battery life has been about 8 to 9 hours which is far better than the prior Hotspots.
      The unit started overheating one afternoon. I can’t say I’m a bit surprised at that, but what is surprising is that it will run steadily as long as the air temp is below 98 degrees. This is a first for Hotspots as they always overheated well before the rated temperature spec. The bad news is the crappy overheat shutdown doesn’t turn off the unit before damage starts to occur, nor does it turn the unit off completely.
      Removing the battery cover seems to help air circulation and overheating some. The button lights are flickering after one overheating but the unit seems to be working fine other than this. It will be interesting to see what happens when it really gets hot here.
      According to the specs 4G LTE takes the least amount of wattage to run so it may not overheat as fast when using 4G LTE. I had the chance to try the modem in the old school 3G EVDO mode as one of my locations is 40 feet underground and that is all that is available at this location. I shut the unit down after 30 minutes as the unit was so hot you could barely handle it even though the temperature underground is around 70 degrees. I would not recommend trying to use this for any length of time if you want the Tri-Band to not overheat!!
       
      My Opinion
      Although Sierra Wireless has made some major improvement in the 3rd generation Hotspot, this is still a unit for the casual user. It is not designed to handle heavy use or outdoor summer temperatures for any length of time. It will be going in my climate controlled cabinet to protect it from the heat next week. I will let you know how it works when the temperature stays below 85 degrees. The improvements in connectivity, reception and stability are worth the investment. As long as you know and adjust your usage for the limitations of the unit.

      Sprint Nextel revealed their second quarter 2012 corporate earnings in a conference call to their investors today and S4GRU was covering for news on Network Vision.
      Network thinning of the iDEN network is complete, taking 1/3 of Nextel towers off air. The Nextel network was built to support 20 million subscribers, but was only supporting 4.4 million subscribers, so it could easily be thinned without [much] noticeable change in street coverage. Sprint also converted 60% of the Nextel subscriber loss into their Sprint subscriber base. Interestingly, they stated that Verizon has been the biggest poacher of subscribers leaving Nextel, grabbing 50% of former subscribers in the last 4 1/2 years. In that same timeframe, Sprint has grabbed 25%, AT&T 20% and T-Mobile 5%.
       
       
      On the Network Vision topic:
      4 additional cities will launch, including Baltimore, by the end of August.*Edit* Cities were disclosed VIA press release following the conference call. They are:
      Baltimore, MD Gainesville, GA Manhattan/Junction City, KS Sherman-Denison, TX  
      Over 2,000 sites are currently online with 12,000 sites to be online by the end of the year
      Network Vision towers are seeing 10-20% additional voice minutes usage per tower, overnight after activating Network Vision. This will equal roaming savings for Sprint, and ESMR will only increase that savings.
      CEO Dan Hesse confirmed that Sprint will be releasing the Motorola Photon Q "in the very near future." It will be a QWERTY slider "with robust business and consumer features." It will also be sporting world phone capability.
      Several hundred Network Vision sites are waiting for backhaul, and will turn on when the backhaul is installed, several hundred more sites have birds nesting on them and Sprint won't be able to turn them on until the birds leave, according to the conference call.
      Sprint sold 1.5 million iPhones during the quarter, even though other carriers saw slowing of sales with rumors ramping up that the new iPhone would support LTE. 40% of the iPhone sales were to new customers. They also stated that iPhone customers require less customer support and are expected to churn less than customers on other phones.
      Mr. Hesse confirmed that Sprint is not looking to change plans in the near future.
      Things are looking up for Sprint. This quarter saw their highest ARPU and their lowest churn rate to date. They posted a larger loss than Q1, but beat their revenue goals for Q2. For more detailed financial information, check the source link below.

      Ericsson RRUS31 B25 + RRUS11 B26
      These are the newest and greatest remote radio units to come from Ericsson. 

      The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rather than two from each RRUS11 that Ericsson originally deployed. 

      All future deployments will be utilizing the new Ericsson RRUS31s. In addition Ericsson are sending crews to their original deployments and swapping out older RRUS11s for these new RRUS31s due to the aforementioned fact that one RRUS31 can do the job of 2 RRUS11s. Weight savings will be significant at sites where there are 4 or 5 RRUS11 B25s that can be replaced by one or 2 RRUS31s. The Ericsson RRUS31 deployment project is known as the 65 Mhz Project.

      Ericsson High Capacity / 4x4/2 MIMO Deployment
      Note the additional antenna + PCS radio.
      Previously Ericsson utilized additional PCS radios and used RF combiners for high capacity setups where they utilized three or more PCS radios. This new setup will utilize a completey new antenna + radio set just like Samsung and run 4x2 MIMO on the LTE antenna / radio set.

      This type of setup is no longer deployed or utilized in new sites. Existing sites will be slowly converted to newer RRUS31 B25 via the Sprint 65 mhz project.
