Network Vision/LTE - Chicago Market

Recommended Posts

I'm reporting it here because I'm sure it will get more attention than contacting Sprint directly. For more than 2 months I have noticed a problematic tower in the Chicago Loop area. It is a Band 41 tower  and its Physical Cell ID is 259. Sometimes I get a string signal from this tower but the internet connection is dead. Any way to report this to the real experts?

 

Thank you,

 

Spam the living hell out of Sprint zone. 

 

They do read the reports from it and plan accordingly. 

 

Another thing you can do is trying contacting @Marci  who can direct you to the pertinent personnel.

Spam the living hell will simply take too long.  Contacting @Marci will get it resolved quickly.  If not, send me a PM, I can reach out to my contact.

I finally got a chance to do some drive testing with Sprint the other day, put an inactive sim in the new Moto G5 Plus and gotta say that thing has some very good RF capabilities because nothing has changed with their network optimization wise in my area but the device was really clinging tight to B41, hanging on well into places I used to drop straight to 3G. It did end up dropping to B26 and then to 3G after about 5 minutes though, only about 1.5 miles from the nearest site. B26 was about -118 dbm, while B13 on my iPhone was -108 dbm, both serving cells in the same place. 

I noticed that the device was on B26 ALOT of the time, with B41 a close second to that, and I hardly saw B25. Other than that nothings changed in 2 years with Sprint's network here (other than a few USCC/Nextel conversions).

Impressed with B41 range but B25 and 26 are the same garbage range/signal I left two years ago. 

 

 

P.S. My suburban home serving site has 3xB41 which I was pleasantly surprised to see.

Thanks for the update regarding the state of the Sprint network here, gusherb.

 

I suppose its a good thing I haven't retried Sprint again, sine the issues I had with them here a few years ago. While I loved the network experience while connected on band 41, it wasn't using that spectrum often enough. It mostly lingered on the awful 5x5 PCS, which usually was under 3mbps. Now that Sprint has 10x10 PCS, I expected it would be better by now, but apparently not. The problem obviously is that Sprint hasn't deployed/densified band 41 enough, so it results in too many of its users connected onto PCS.

 

Now, those who think I'm being negative and trolling on Sprint by saying that, hear me. How is it "negative", when I've given so much praise to Sprint for its band 41 spectrum being great as it is? I've written here dozens of times about how great the band 41 network experience is in the town of Schaumburg, where Sprint actually does have quite a good network setup of there, which if Sprint matched that in their other markets, Sprint would be an amazing wireless carrier. Nothing negative nor trollish of me saying that.

 

The thing that bothers some, I think, is when they confuse my words with "bashing" Sprint, when it is Softbank I'm being critical of. It isn't a secret that I resent what Softbank has done with Sprint, as I believe that Sprint would be in a much better condition now if Dan Hesse was still in charge, with his focus on getting deployment and densification of the network, ahead of the financials. For instance, the Chicago area PCS issues wouldn't exist with Dan Hesse's plans in place. Two years later and the same network issues here is not good at all.

Everyone is entitled to opinions, and you have to expect push back from someone who does not agree. It is highly unlikely that things would have gone as nicely as you think under Hesse. He did well when he came in, but that plan that was initialized right before he left likely would have resulted in Sprint not existing any longer.

I agree with you here about this regarding others.

 

I know there are a few differing viewpoints regarding the Dan Hesse situation, some of which resemble the political issues of spending vs austerity. The current Sprint, under Softbank, with all of its financial restructuring and cautious spending, in contrast to Dan Hesse's focus on spending big. Some think one way is better, and those that think the other is. All a matter of perspective. The important thing is that everyone realizes that, and respects each others perspectives, without labeling the person as something bad for discussing those perspectives, so long as they aren't insultive, harassing, threatening, and the like.

 

Of course, I view the situation with Sprint as such where I think it is important to spend on the network, then get people over once they see how Sprint's network is superior, which I believe it can be with deployment and densification. Still, this doesn't mean that I can't understand in some ways why this isn't happening. Softbank probably is hoping for a merger with T-Mobile, which if successful, gives them the added network Sprint needs, without having to go through the hassles of building anew. Plus, it gives them instant customer additions, without having to "win" them over. In a sense, it is a better use of their money spending it for a merger.

 

I think there is a compromise here though, which is why I think Sprint ought to deploy their spectrum on all the sites they have of which they can deploy onto, giving the network a much needed improvement, while delaying the densification projects until there is some definitive direction on their future prospects.

Unless sprint is using different panels now, then this is not Sprint. They are very large mainly in height. I was thrown off because the base station is in a metal cabinet on a raised platform instead of a hut.

Got my dad on the free sprint promo with his Moto G5 Plus. Not sure what the deal is but the network seems a lot slower than it was 2 years ago. I realize the G5 Plus doesn't do CA (last I heard anyway), but we have 3xB41 and I've sat in the same spot testing as the phone jumps across each of the 3 channels and they're all equally slow. I mean like 1-6 Mbps slow, so even with CA working it wouldn't amount to anything impressive. At home on my unloaded tower I can only get up to about 28 Mbps which is exactly what I got 2 years ago when only 1 B41 carrier existed. I even tested back in April on an iP7 that had CA and could only do about 45 Mbps, though it did spike up to 80 very briefly.

 

So that leads to my question, is there really that many sprint subs around? (I doubt it), have they let backhaul go, or are they just doing a really poor job at optimization? Cuz it makes no sense to me how they could be so slow with 100 MHz of deployed spectrum on LTE.

Combination of way more Sprint subs in major markets and user usage patterns. As more users use their phones to do more, puts more strain on the network. Also gotta have a CA device or bust.

 

The funny thing is I've been noticing better optimization between bands as densification ramps, but that isn't enough for an older device to keep up, (MASSIVE MIMO will definitely help for older devices)

Chicago is one of sprints top markets that they've always used every single ounce of spectrum. So yes, contrary to your belief, there is a huge amount of sprint users which with the ever increasing data usage means more congestion even if there was 0 subscriber adds especially since the 4th 5th 6th B41 carriers are not in operation.

I just have a hard time believing they're so congested with 100 MHz of deployed spectrum while in my county specifically, Verizon does fine at 60, AT&T runs anywhere from 50-80, and T-Mobile running 40-70 MHz.

Again sprint has the the highest if not one of the highest subscriber counts in the market.

 

Add high subscriber counts, ultd data, increased high data usage apps and streaming, lack of network investment in terms of additional site density unlike the others means all else equal the network will be less speedy compared to less loaded and high density networks.

 

It's not an apples to apples comparison especially when you get into 4x4 and 256QAM, that is live on ATT AND tmobile and the innumerable small cells Verizon have deployed.

 

Tldr: standing still for a year means others catch up.

Do you know for a fact the subscriber counts are very high or are you basing that statement off the person who revealed that info for several markets some years ago? Cuz if I had to guess, I'd still say AT&T was number 1 here followed by T-Mobile and sprint and then VZ fourth.

To bad Sprint can't do wideband LTE there. If they have 2carriers I'm sure B25 CA is there or on the way.

They can and still have 5x5 worth of CDMA. They hold 50 MHz of PCS here and 30 of it is contiguous.

 

As it stands now they have a 10 MHz channel and a 5 MHz channel. If they enabled intra band that could be 15 MHz DL today.

This beyond frustrating! For the last couple of months LTE service drops for a few minutes at random time in the Chicago Loop area (right by the Willis Tower). When I check in the iphone engineering screen, the phone is latched to band 41 and antenna id 83. Any recent issues in the area? Thank you.

Just had a similar experience in Wheaton/Naperville for the first time yesterday. I noticed my phone was showing no service while at work, which normally has good coverage. It lasted about 30 seconds before going back to normal. No airplane mode toggling helped during the 30 second window. At dinner my dad and I left our scp up to see if it was just me or not. sure enough, every 10 minutes or so both our phones would totally drop all connections simultaneously.

 

Don't know what's up, I've never seen this particular behavior before.

      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.

      A standard Ericsson Network Vision 1.0 site with 3 RRUS11s where two are dedicated to PCS and one to SMR.  

      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.

      3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.
