    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.

    Interesting note in here: https://ecfsapi.fcc.gov/file/10326217025032/March 26 Sprint Ex Parte.pdf Sounds like they're trying to get the EBS licensing changed to better utilize the 2.5 GHz band. - Trip

    Tim YuSprint 4G Rollout UpdatesSaturday, April 7, 2018 - 6:54 PM PDT A year ago Sprint and Open Mobile announced the beginnings of a joint venture whereby they would combine their network assets and operations together to create a better more competitive alternative on the island. In late 2017, the deal was consummated which gave Sprint access to Open Mobile's spectrum holdings in the PCS 1900 range and, more importantly, the 750 MHz Band 13 block. This LTE Band 13 is almost exclusively used by Verizon Wireless as the basis for their LTE network. In comparison to Sprints SMR 800 MHz holdings it is 20 MHz in width meaning that Sprint is able to utilize a 10x10 MHz lowband LTE carrier whereas Sprints Band 26 800 MHz is limited to 5x5, 3x3, or even non existence as in Puerto Rico due to spectrum hoarders and other issues pertaining to the IBEZ. With this spectrum, Sprint is now able and has begun the deployment of a triband 750 / 1900 / 2500 network in Puerto Rico! See the following screenshots from S4GRU PR / VI market thread users! Note: UARFCN 5230 is 751 / 782 MHz center frequency. LTE Band 13 runs 777 - 787 / 746 - 756 which means it's smack dab in the center perfect for a 10x10 MHz FDD LTE carrier. Thanks to imatute and smooth25 for the finds!

    Just returned to Seattle to a pleasant surprise — full LTE throughout SeaTac airport! Never thought this day would come. Service was -102 or worse on L1900 or L2500 before. Now signal on L1900 doesn’t drop below -90.

    Ericsson AIR6488 B41 Massive MIMO Antenna Radio Unit This 64T64R Massive MIMO units will be likely found in Ericsson vendor territory from network vision days. It will be easily identified by it's lack of an external remote radio like Sprints typical LTE equipment and its size being significantly smaller than Sprints existing 800,1.9, and 2.5 equipment.

    Oh, no no no. Unfortunately, you're giving humans far too much credit. Sadly, you're wrong; people are that stupid and even orders of magnitude more so. I'm astounded everyday at the stupidity that abounds all around me.

    It would be amazing if Sprint was able to finally fire up 256QAM+4x4MIMO on most Sprint B41 equipment and also some basic level of Massive MIMO in April.

    Got a chance to compare the GS9 against the V20's radio. Holy Jesus! The GS9+'s radio performance is in another stratosphere! 30-60% better speeds on average. Also holds onto B41 quite a bit more. Bravo Samsung bravo!

    It seems I’ve come home to another pleasant surprise — a new site with hexadecaport antennas located on Microsoft building 43. I can’t connect to it yet, but it’ll definitely improve coverage and capacity in the surrounding areas when it comes online.

    No, people are incredibly stupid, I assure you. It's not even debatable, unfortunately.

    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.

    This will not be an all Sprint complaint thread. Comments about the admin fee only. Stay on topic to avoid moderation. Thanks. Robert

    Highly likely that it's Sprint. John specifically mentioned zayo in his 5G chat with fiercewireless. https://www.fiercewireless.com/5g/sprint-promises-to-launch-nationwide-mobile-5g-network-first-half-2019-and-to-raise-unlimited

    4 Rx diversity at eNBs yields moderate to substantial site coverage improvements. Likewise 4x2 at UE yields improvements for all devices regardless of 4x4 MIMO compatibility. This is the same type of configuration tmobile, Verizon, and att uses for ever increasing amounts of their low band setups. I view the documents as equipment capability considerations. Hardly any sprint market is going to use 5 or 6 or more cdma carriers in the coming months and years and they list those capabilities in those documents.

    These fees really should just be baked into the mrc for whatever plans they sell. I get having sales/local/911 fees separate but little administrative charges like this always irritate me no matter who the service provider is (phone, cable, gas/electric etc).

    A ground mount B25-only site near Endicott is spitting out 10x10 now as well. Sweet! Looks like it’s everywhere.

    noticed 10x10 2nd carrier in multiple subway stations. Also noticed it a few times around manhattan. One thing i noticed is that my phone will not do CA with the 10x10 and 5x5 carrier. But on site that haven't been updated to 10x10 the phone still does CA
