  3. Dave YeagerSprint 4G Rollout UpdatesTuesday, April 3, 2018 - 6:20 PM PDT Exciting times for those of us who track Sprint Macro sites and signals. Sprint has accomplished a lot during the last few years in many places. Even during a period of reduced capital expenditures. Progress has been made by increasing bandwidth and adding carriers to LTE 1900 MHz, adding LTE 2.5 GHz macro and small cell sites, adding 3x3 LTE 800 MHz to many existing sites near the border, and working to eliminate 3G Only Ground Mounted Radio sites by adding LTE in many places*. Some of these improvements have been offset by ever increasing data demands that have doubled every 18 months. For maximum gain, a new plan was needed...Next-Gen. Since late Fall 2017 Columbus S4GRU members have been tracking new permits in Ohio trying to figure out Sprint’s Next-Gen plans in detail. These permits soon made it obvious that multiple site configurations are involved. In late February / early March three Next-Gen sites were found in the Columbus Market. To ensure that these were not just isolated test sites, two identical Next-Gen sites were confirmed in the Cincinnati Market about a week ago. These are new antennas and are a different scenario than described in the prior S4GRU Wall Article on 16 port Triband Antennas. Note that these new antennas (center) are about the same size as the 1900/800 MHz dual band antennas, except thicker and cover 2.5 GHz / 800 MHz. There are 10 ports on the bottom, excluding the 4 AISG ports, for 8T8R 2.5 GHz and 2T2R 800 MHz (plus 2T2R 800 MHz from Network Vision antenna/RRH). The site diagrams from Connecticut list them as Commscope DT465B-2XR-V2, which matches our photos. These new antennas are combined with a 2.5 GHz 8T8R RRH and another 800MHz RRH (a few permits list just one 4 port 800 MHz RRH) and always been found with existing hexport dual band 800/1900 MHz equipment. ** Sprint’s desire to add 2.5 GHz to all sites is well publicized. But why two 800 MHz RRHs? To allow 4x4 MIMO for 800 MHz LTE. While only some tablets will fully benefit from 4x4 MIMO given the antenna size requirements, all devices will benefit from the significant signal propagation and stability improvements over 2xT/R diversity. At the cell edge this is especially true. This will be a major improvement for technologies such as VoLTE where weak signals can wreak havoc on voice quality and even usability. Four Sprint scenarios were noted in some of the Connecticut information. Besides the two scenarios covered in this and the prior wall article, there is a ground mounted radio scenario, which is dated February 28, 2018 -- well past the changeover to Next-Gen antennas seen in the late Fall 2017 permits. Only the Triband decaport (10 port Antenna) is visible in the tower with diplexers and RRHs near the ground providing only 2T2R for 800MHz, 2T4R for the 1900MHz and 4T4R for the 2.5GHz, as shown below: *** *** Below is the current status of our 2017+ permits for the Columbus market to give you an idea of where these antenna scenarios will be used more often. Note that while there is extensive permit information for the Columbus market, not all jurisdictions put permit information online plus accuracy and detail varies. There is at least one Sprint Next-Gen Scenario remaining. Keep watching your local sites, especially if you see improved Band 26 LTE 800 or new Band 41 LTE 2500 signal or GCIs. Report anything new to a S4GRU forum. Include pictures and screen shots. Others will guide you to help figure out what you have found. *For details for my market for 2017: http://s4gru.com/forums/topic/1904-network-visionlte-columbus-market/?page=219&tab=comments#comment-526696 Other spreadsheet markets in this region have similar stories to tell. ** Wiring Diagram source: http://www.ct.gov/csc/lib/csc/ems/east_windsor/southmainst/sprint/em-sprint-047-180126_filing_southmainst_eastwindsor.pdf page 61 of 66 *** Ground mounted Radio Scenario: http://www.ct.gov/csc/lib/csc/ems/stratford/hawleylane/sprint/em-sprint-138-180302_filing_hawleylane.pdf page 7 of 107 Many thanks to lilotimz and kineticman for their assistance with this article.

Record speeds for my older LG V20, a S9/S9+ user should check it out.
  6. Was this the result of trying to obtain information for S4Gru?
  7. The left antenna facing towards you has the band 25 LTE with two 10x10 carriers, likely with Band 25 Carrier Aggregation (I did not test for that). The smaller antenna facing towards you on the right with the single RRH and more wires has the Band 41 with 5 carriers for a total of 100Mhz of spectrum. It needs a Samsung Galaxy S9/S9+ to tell its maximum level of Band 41 Carrier Aggregation.
  8. Correct. I meant to specify that. Edited. Thanks.

    Sprint Tmobile merger Disc.

    The big difference in T-Mobiles LTE approach was doing urban areas first, then working outward. Sprint started with rural areas then worked inwards. T-Mobile benefited more customers sooner, thus attracting more customers (assisted by better marketing) and thereby reaped the rewards of better cash flow.

    Sprint Tmobile merger Disc.

    iirc RRHs add about 20% to the performance of a site, which was a primary reason for Network Vision. Don't forget the 3G reaches further than LTE. I often see sites in rural areas from other carriers that have no RRHs in the countryside. Sprint would have needed more sites in many places without Network Vision due to the limits of Ground Mounted Radio LTE.

    Sprint Tmobile merger Disc.

    Softbank is a conglomerate. Sprint is not their most important investment overall. They can still complete their strategy by owning a smaller slice of a bigger wireless company, especially one that generates its own cash flow. The money Softbank initially planned on putting into Sprint was consumed by a bidding war with Dish over Clearwire. It is hard to raise dedicated money post buyout. Sprint going alone has a lot higher risks than a merger (both are significant risks), especially when increasing cost of capital in markets is likely. Besides the technical aspects, Sprint needs far better marketing and T-Mobile can likely deliver in that area. As a customer, everything will depend whether I get quality service where I need it post merger + a year or two. Otherwise I will go with the carrier that serves me best. Eliminate my favorite towers or redirect them would accelerate this. If they get updated to Next-Gen before the merger, the odds will increase that I will stay and buy new phones.

    [PSA] Sprint begins Band 13 deployment in Puerto Rico

    Which is why it is good that Sprint reached this deal on Band 13 (700Mhz). The timing of the hurricanes occurred before Sprint decided to put band 41 on every tower. Being now run by the joint venture, the Sprint sites in Puerto Rico may no longer fall under this edict and instead operate more like Shentel. A quick search of ED and BR licenses indicates that Sprint has enough for 20+20+15 over the entire island and then some. Virgin Islands appears to be not so lucky.

    Network Vision/LTE - Cleveland/NE Ohio Market

    We need more help to get a better picture of improvements. From what we can tell there are lots and lots of improvements occurring in the Cleveland market. Various contractor contacts indicate it may be a site every other day. Help can be a simple as installing Signalcheck Pro (about $3) and sending in the logs which records the best signal location per site sector per band carrier. Other markets get half their site information this way just by people sharing their logs as they go about their normal routine. Taking pictures of sites that are new or changes at existing sites helps even more. Take pictures of the site and a couple of pictures around it so we can best locate it. Street information is essential, but a screenshot of Signalcheck Pro showing the latitude longitude for the site or close to it is even better combine with those pictures. Of course the Cleveland Sponsor has more site info (same donation required - same as a cost of your typical lunch is recommended) and the Cleveland Premier covers band 41 LTE 2500/2600 and band 26 LTE 800 in detail for another donation. Donations are used to keep this site running (volunteer staff help also essential). Sent from my LG-LS997 using Tapatalk
  14. The real issue that remains for Sprint network improvements is cash flow. The reality is Sprint is really just part of a conglomerate, rather than being integrated into Softbank. Thus Softbank will help them on the edges, but it is really up to Sprint to improve themselves. Masa likely told Marcelo to reduce the B41 rollout, after all he admitted he lost heart in Sprint. The current round of upgrades was approved by Masa, but the money was raised by Sprint. Unless this money is in the debt covenants, Softbank could decide to use it elsewhere once again. With data usage doubling every 18 months, refarming could only go so far, thus B41 expansion was the only real choice at this time. It helps when one of your competitors recommends that strategy for Sprint. 5 years ago they did not have the cash.
  15. I would assume so for Dallas. Chicago is Samsung and Los Angeles is Nokia, both of which are likely going through the same approval process at this time.
  16. From Ericsson: "This radio (AIR 6468 B41) is designed for use in LTE mobile telephone system. This radio operates in Band 41, the transmitter and the receiver from 2496 MHz to 2690 MHz. It supports channel bandwidths of 15MHz and 20 MHz. The radio supports modulation types of QPSK, 16QAM, 64QAM and 256 QAM. The radio unit supports carrier aggregation. The radio has the ability to be used in a RBS system configured for 3GPP FD-MIMO and beamforming technologies as an Advanced Antenna System. This radio will in normal mode operates at a maximum power of 1.875W per port at the transceiver array boundary (TAB) connector. The radio has 64 TX/RX ports."
  17. From earlier today, another Sprint Next-Gen 10 port 800/2.5 upgrade in progress at a Crown Castle site near Mansfield, Ohio: Several more of these sites were confirmed, along with a 16 port Triband site, making Cleveland the first market in our region with two confirmed Next-Gen scenarios. The contractors said they have done 10 sites like these. This does not include the other tower companies possible work.
  18. In the first article, from RCRwireless, it only mentions that the first Massive MIMO deployments will begin in April. Sprint has 26 days left. One site in each of the first three cities would meet their criteria. Assuming FCC approval, which typically means going through a private testing lab to meet established criteria, they should be able to make this target. To meet our expectations is a totally different matter. 5G can not come soon enough. In reality it will occur one step at a time. At least we know Sprint has raised the money for these projects and Next-Gen work has begun in many places.
  19. Yes. There are many Next-Gen Permits making their way through the Connecticut Siting Council or approved. Besides those mentioned in the footnotes, here are others that I found: 10 port 800/2.5 Antenna: http://www.ct.gov/csc/lib/csc/ems/montville/cookrd/sprint/em-sprint-086-180124_filing_cookst.pdf http://www.ct.gov/csc/lib/csc/ems/newmilford/boardmanrd/sprint/em-sprint-096-180305_filing_boardmanrd.pdf http://www.ct.gov/csc/lib/csc/ems/westhaven/derbyave/sprint/em-sprint-156-180226_filing_derbyave.pdf 16 port Triband Antenna: http://www.ct.gov/csc/lib/csc/ems/manchester/hilliardst/sprint/em-sprint-077-171204_filing_hilliardst.pdf http://www.ct.gov/csc/lib/csc/ems/manchester/lakest/sprint/em-sprint-077-171214_filing_lakest.pdf This in not an exhaustive list.
  20. Almost 20% of the dual band 2.5/800 permitted sites in the above table are locations that already have 2.5. I would assume the dual band 2.5/800 scenario will be targeted to sites that need more 800MHz capacity whether or not they already have 2.5. The 16 port Triband scenario is strongest with band 41 only sites. This may vary by market. Sprint also has one or more Next-Gen Massive MIMO configurations, but we have not seen the details other than Sprint will have 64T64R*, there was discussion of horizontal and vertical oriented units, and Sprint will deploy thousands of Massive MIMO radios. Once they become certified by the FCC, we will know more about the Massive MIMO units. Given that Sprint has not publicized the 800 MHz enhancements that frequently occur with the known Next-Gen configurations, I feel they will likely include such improvements with the Massive MIMO scenarios. Outside of band 41 only sites getting the 16 port Triband Antennas, Columbus has no Next-Gen permits for its densest areas or its many high capacity sites. Being America's 14th largest city**, and access to virtually all band 41 spectrum to make a transition to 5G quite easy, we are hopeful that we will see Massive MIMO configurations soon. With its far greater density and vertical challenges, New York City likely ranks higher on Sprint's list for Massive MIMO. * https://www.rcrwireless.com/20180305/carriers/sprint-cto-massive-mimo-secret-weapon-tag17 https://www.fiercewireless.com/tech/sprint-to-turn-massive-mimo-6-cities-april https://www.theverge.com/2018/2/27/17057502/sprint-5g-lte-antenna-rollout-gigabit-atlanta-chicago-dallas-houston-la-washington-dc https://www.ericsson.com/en/news/2018/2/ericsson-a-key-partner-in-sprints-5g-ready-massive-mimo-deployments http://newsroom.sprint.com/sprint-unveils-5g-ready-massive-mimo-markets.htm https://www.wirelessweek.com/news/2018/02/sprint-readies-5g-plans-massive-mimo-deployments-6-cities https://www.allaboutcircuits.com/news/sprints-bid-to-have-5g-in-2019-using-massive-mimo/ https://www.rcrwireless.com/20170620/news/sprint-and-samsung-set-to-roll-out-massive-mimo-tag4 https://www.nokia.com/en_int/blog/nokia-sprint-trail-blaze-5g-massive-capacity-blistering-speeds https://www.fiercewireless.com/wireless/sprint-cfo-5g-will-allow-sprint-to-finally-change-perceptions-about-its-network ** https://en.wikipedia.org/wiki/List_of_United_States_cities_by_population
  21. You have the same RRH configuration with two 800 RRHs, a 1900 RRH and a 8T8R. The antenna housing is slightly different. Likely a Commscope variant, but if you wanted to be 100% certain, we need photos of the bottom ports or a part number. I understand that in some cases, your sites have two 1900 RRHs so five RRHs total per sector would then also be acceptable.
  22. Mike, I sent in diagnostics last evening for the last GCI showing an AT&T LTE site via Sprint Roaming from an hour before despite having passed many Sprint LTE sites which had been see by SCP.

    Network Vision/LTE - Columbus Market

    2017 S4GRU Confirmation Report for Columbus 6 Ground Mounted Radio sites with Remote Radio Heads added 7 sites confirmed with 1x800 CDMA 119 sites upgraded to Band 25 LTE 1900 5x5 plus 2nd Carrier 10x10 38 sites upgraded to Band 25 LTE 1900 10x10 44 sites with new Band 41 LTE 2500/2600 81 Band 26 LTE 800 confirms (mostly 3x3) 2017 Band 41 Totals by Type: Macro Sites 209 8T8R 121 Mini Macros 3 Tri Sector Split 8T8R Small cells 6 Air Harmony 1000 (5 with directional antennas) 17 Air Harmony 4000 (2 at Sprint Stores) 4 Alpha Wireless Concealed Access Nodes (3 variants) Looking Ahead to 2018 Shentel At the start of 2017, it looked like Sprint might inherit the nTelos Sites outside of the nTelos Market near Portsmouth (Columbus Market) plus Gallipolis, Marietta and Parkersburg (West Virginia Market). In April 2017 an Expansion deal was signed by Shentel with Sprint for at least the nTelos sites in these areas. We have since learned it will include the Sprint sites in these counties as well. The Shentel sites added around Portsmouth have been removed from our sheets and maps. The 086 sites (Samsung) will be removed as they are replaced with ALU sites around Portsmouth. Columbus could inherit West Virginia Market remnant sites in Noble and Jackson counties. Changing them to 086 could be low priority. New Permits Near the end of year we noticed a dramatic increase in permit activity. The summaries released to the public are often scanty in details and often only represent a fraction of permit activity. Here is what we have recorded since the start of the year that are open: 24 Network Vision sites to get Band 41 LTE 2600 6 Outstanding Small Cell permits (Band 41 LTE 2500, includes 2 billboard sites) 3 Network Vision Ground Mounted Radio sites to get Band 26 LTE 800 11 former Clear sites to get Band 25 LTE 1900 and Band 26 LTE 800 9 other sites are to have other work performed (uncertain) Of course these permits may also not be completed. All of us will just need to be observant for new construction. New permits were being issued up to the last business day of 2017 and thus are expected to continue. Forth Carrier Band 41 LTE 2500/2600 forth carrier has also been promised for sometime in 2018. It will generally just affect the large metropolitan areas. Third carrier is a prerequisite. Note: I typically provide this information earlier in the year, sorry for the delay. This was posted in Premier on January 2 and should have been posted here two weeks later. If you become a Sponsor member by making a donation (cost of your typical lunch is recommended) you will know where the Network Vision sites are located and whether they have LTE or 1x800 and other important features. Premier membership adds band 26 and band 41 information. This level is the most active. There is also honorary membership level.
  24. Great to see confirmation that the isolated WV market Logan WV 3G site is going to Shentel and will be upgraded. I would love to see and similar maps for Shentel's April 2017 expansion areas in Ohio and Maryland. Thanks again. Sent from my LG-LS997 using Tapatalk
