More updates.  The tower on the Mag Mile at Walton and Michigan Ave finally turned 4G.  Hooray there is LTE on North Michigan ave.

 

Sprint Care on Twitter told me that the two towers in the West Loop that are still stuck on 3G only are slated to be LTE active within the next 90 days.  Looks like they are some of the if not the last towers scheduled to be turned LTE downtown.

I live on the West Loop!!!! Yes, just in time for me to get the iPhone 5S!!! With the conversion to 4G that means that those towers are LTE at 800 and 1900?

I can't say for certain if they will have 800Mhz LTE but 1900Mhz LTE for sure yes.  They are located at Washington/Loomis and Kinzie/Sangamon.

Nice! Both towers are less than a mile away from me. What is the range of a 1900 signal? 800? 2600? Just curious.

I don't know, good question for one of the more technically minded posters on the board or one of the admins.

Typically in dense city like chicago a 1900 site is about 1 or 2 miles in radius. Downtown has more cell sites(a few blocks), because more people. If your getting the iphone 5s or 5c, u wont be able to get 2600. So I wouldnt worry about it, 1900 and 800 lte(which iphone 5s/5c supports) should start being turned on the end of this month, then give them some time to get to all sites. Also all sites need to have 4g on 1900 before 800 of course(need fiber backhaul). I have 800 voice on my phone right now and it keeps a site a lot long then 1900. So with the new iphone, u will have 4g in a lot of bulidings that u didnt before.

Went to Joliet for the NASCAR race on Sunday. Last year there was only a sniff of LTE in one corner of the track. This year, I had a very strong signal everywhere, but as soon as the place got busy, it became *completely* unusable. It took a solid 10 minutes to load a weather map. I gave up trying to check Facebook, Twitter, etc and didn't even bother with a speedtest. It was painful...and very disappointing.

Same thing that happens to me at every event at Soldier Field, Wrigley Field, United Center, and other concert venues.  Sprint seems to have more capacity issues than spectrum issues.  Quite strange.  To me this implies they have made little to no progress with backhaul in the market.  If true, that would put them extremely behind schedule if we are to believe what some of the mods and people in the know have said about the original schedule.

Meh, thats like the dumb people's theory that if you build more highways or expand current ones its just going to mean more traffic.  Thats not true.  That's now how demand forecasting and thus transportation planning works.  Im sure the same is true here.  If backhaul is gained it doesn't automatically induce enough new traffic (or subscriber gain) to negate it's installation.  There is a build up of value to current and new subscribers before the recently deployed back-haul reaches its capacity or bod down point, could take months should take years.  Same with highway expansion, which is why the residents of Lake County are retarded in their resistance to expanding Route 53.

Oh, they should certainly expand 53 and the backhauls. My intent was that neither are upgraded fast enough to keep ahead.

Oh yeah that is 100% true.  Telecom providers, IDOT, Tollway Authority, etc, all move too slow to actually produce the impact required by the motivation for the infrastructure expansion in the first place to make a difference.

I'll be visiting Chicago soon, so I'm curious, being a launched LTE market with 98% of NV sites accepted, and  78% of LTE sites accepted how is life on Sprint's network now? Should I expect to pick up 4G in most places in the city?  I'm on a S3 so it's 1900mhz only.  How are the speeds?

It depends on how each site is set up. In rural areas, you can get 10-15 miles out of a 1900 site, 20-30 miles out of an 800 site, and 3-4 miles out of a 25/2600 site. In urban areas, each can be configured down to a couple of blocks to fit in more sites for capacity.

All the backhaul in the world won't help if the airlink is saturated. Each site can only handle so many simultaneous connections before things bog down. There is simply no way the Macro network can handle that many people. There is no Macro network that can. The only way to deal with these types of events is either with a DAS system, or small cells, or public WiFi.

Ok so here is the real reason Sprint's service, even though its all active LTE, sucks so bad in and around Solider Field and Museum Campus.  Not that they would ever say this, but long story short, their infrastructure is lesser (less towers in the area) and farther away, at least compared to Verizon. Period.

 

See the map below I found from opensignal.com for the South Loop area.  Verizon has an entire series of towers within hundreds of feet of one another right at Solider Field and within the Museum Campus area.  The have systemically identified and planned to cluster towers in this area to provide coverage and service to one of the most highly trafficked areas of Chicago.

 

Sprint has a cluster of towers over by State and 14th, a little over half a mile away from Soldier Field.  Also a couple towers at McCormick Place, about 3/4 miles away.

 

Verizon has a tower within the Solider Field grounds, another about 1000 feet away at the Field Museum, and another one at the Roosevelt Metra Electric station about 1500 feet from the Field Museum, as well as a tower at McCormick Place as too (3/4 mile).  VZW is saturating the Museum Campus area with capacity and coverage, Sprint is not. 

 

So no wonder none of my friends on Verizon have the same no calls, no texts, no data, all timeouts problems on gameday's (or concerts) at Soldier Field that I and my other Sprint friends do.  If Sprint doesn't put up a micro site or DAS they either don't know (in which case I don't want to be with a provider that doesn't know their own network) or don't care.

That map doesn't seem very accurate. I have a whole cluster of towers near my house, not a single mark on the map.

A sprint person responded to a similar post I made on their community forums.  His response was, "Sprint would love to have a tower at Solder Field, but who is the official sponsor of the NFL"?  I find that a total BS answer.

 

A.  Verizon wasn't always an official sponsor, Sprint was for most of the 2000s

B.  Sprint just received $5B in capital from Softbank, if they wanted to invest in mobile microsites or DAS they could

C.  If Sprint really identified this area of Chicago as under capacity and under performing as we have they could do something if they wanted.  A tower on the Field Museum, a tower across Lake Share on the Museum Park Towers, etc etc.

D.  To do nothing in such a heavily trafficked and impacted area to tens of thousands of subscribers implies they either don't know (in which case they are a bad company) or don't care.

Are those typical or optimistic? For my plots, I was using using seven miles for PCS. I got that by measuring from quiet spots to area towers.

Anyone have any numbers as far as how much real world traffic saturates the airlinks? I'm not talking the 37.5 meg best case.

 

They should have had all of that in 3G years ago.

15 is best case scenario, but 10-12 is pretty regular for those rural highway sites. Pretty common along my drive from Springfield to KC, and on the drive from KC to Denver.

I don't know that info off the top of my head. You'd probably have to drag AJ into this to get a good answer.

Ah, yeah, but that's up to the venues. Sprint can approach them about installing something, but it's up to the venue to actually get it installed.

      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.

      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.
