  1. Tim YuSprint 4G Rollout UpdatesJanuary 26, 2018 - 5:30 AM PST [Edited: 1/28/18 to include additional information on Samsung 4 port 800 MHz radio] [Edited: 2/2/18 for photograph addition of an Ericsson setup] The Triband Hexadecaport. The newest development of Sprint's recent network expenditures. This is a new triband antenna configuration now being deployed by Sprint that is able to do 4T4R MIMO on both 800 MHz and 1900 MHz in addition to 8T8R MIMO over 2.5 GHz. All in one single antenna. Previously, Sprint typically utilized two different antennas with one from Network Vision days being a hexport dual band unit that supports 800 MHz and 1900 MHz. While 2.5 GHz was an additional antenna and radio unit added on later. Some sites utilized (and may continue to utilize) another triband antenna model. This older generation triband antenna is a decaport (10 port) triband unit that support 4T4R on both 1900 MHz and 2.5 GHz with 2T2R on 800 MHz. This meant that an 8T8R radio would have its capabilities decreased as a result of going from 8T8R to 4T4R. With the development and deployment of this new 16 port triband antenna, Sprint is now poised to offer 800 MHz 4 antenna transmit and receive diversity alongside 1900 MHz, while 2.5 GHz is able to fully utilize the capability of an 8T8R radio. This means that the full capability of Sprint's 800 MHz, 1900 MHz, and LTE Plus (2.5 GHz) network can be utilized from a single triband antenna panel. Removing the limitations of the previous go-to triband antenna model. Because of these limitations, Sprint did not deploy the previous triband antenna panel in a wide scale. Now they are likely to deploy these more commonly. In fact, we are already seeing this occur in Washington State, Pittsburgh, and other places en masse.

Samsung and Sprint has a new 4 port 4T4R 800 MHz RRU that will be able to do the job of two existing 2T2R 800 MHz RRUs that will be deployed alongside this new type of antenna. This new Samsung 4 port low frequency radio is also available in Band 13 750 MHz for deployment in the Puerto Rico market due to the Sprint Open Mobile deal. Photograph Source: Chris92 Ericsson Setup Source: mdob07 This type of setup is yet to be seen in Ericsson or Nokia - Alcatel-Lucent territory. If you discover these in other vendor regions, be sure to post about it! ****If you're in Ericsson or Nokia / former Alcatel-lucent territory then replace the Samsung radios with the relevant Nokia, Alcatel-Lucent CDMA / LTE and Ericsson radios depending on region.***
  2. 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!

Nokia Networks (formerly Nokia Solutions & Network [NSN]) FZHJ Flexi Multiradio 10 BTS RF module 2.6ghz Model: VBNFZHJ-01 / FZHN Assigned Vendor Region Full Build Ericsson upgraded Network Vision + Nokia 8T8R setup Special Case "Tri-Band Antenna" Setup Deployed for engineering reasons these sites do not deploy a dedicated 8T8R antenna for 2.5 but instead opts for a three frequency antenna that supports 800 MHz + 1900 MHz and 2500 MHz. Due to size constraints for the antennas they limit the 8T8R RRUs to 4T4R mode (4 Jumpers from radios to antennas).

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.

    Sprint Tmobile merger Disc.

    Continuing on that chain... When Tmobile and ATT first began HSPA deployments in late 2000s, most of the was radios inside cabinets but as it got to the turn of the decade they began using remote radio units. Some of these early generation remote radio units were capable of supporting LTE (Ericsson RRUS01/02s) with base station modifications!!! A few of these setups still remain in place too though augmented with newer equipment.

    Sprint Tmobile merger Disc.

    That's Incorrect. T-mobile did a full rip and replace when they added Nokia to more than half of their regions to replace a hodgepodge of legacy nortel, lucent, and eventually Huawei (through MetroPCS) equipment. Though they had newer equipment in most places capable of supporting HSPA and DC-HSPA, significant ground and radome level modifications were done to bring it up to speed to support LTE service. In many cases it means ripping out the entirety of whats already in the existing base stations. The nature of them also having more recent equipment capable of HSPA means that the move from that to LTE went fairly smoothly as backward compatibility was easy to handle. Legacy Sprint and new modern eNB? Well.... ask those that lived in Motorola regions or those that were in Samsung regions where modern eNBs could not communicate over CSFB to legacy nortel and lucent equipment... Edit: addedum. Sprint was also deploying CDMA 1x800. Legacy equipment cannot be sourced for that as Lucent, Nortel, and Motorola no longer existed and those equipment were long depreciated / EOL'd.
  7. As of last check the free year service promo was about 1% of adds. They do 0 advertising, 0 promotion, and 0 in store work on it so it's primarily limited to the techy folks with the know how.
  8. There's multiple VZW 5G CPEs and 1024T1024R 29 / 39 GHz Massive Mimo Radios that have gone through the FCC. Neat stuff. I'm expecting to see it in my area in the coming months and maybe even at my parents residence....

    dual band / multi band radios will take care of that issue. Lots of these new types coming through. ie B13+B5, B2+4/66, B5+14, etc etc.

    It began sometime last week or the week before. Robert updated the forums to the new IPboard security update but I think we had some reports of it happening even before it. We've reinstalled the tapatalk plugin several times to try and fix the issue but nothing. What's weird is that you can sign up an account to the forum on taptalk but can't login with it. So tapatalk can communicate with the forum at least for that but fails for logging in. I actually would recommend people contact tapatalk support and see their thoughts as Robert has done everything we can on our end AFAIK.

    Known problem affecting a number of users. Robert and myself attempted to diagnose / fix it from the our end to no avail. We're not sure what's the issue at this point as well...
  13. I mean end of year 2018 is getting awfully close...
  14. Zis -->> http://s4gru.com/entry/428-discovery-time-next-gen-dual-band-10-port-800-25-configurations/
  15. Give an exact location and we might be able to figure it out. It was either they stick with 3G / 1x or they get B25 via a new LTE carrier card and backhaul. B25 may not be great but it's still something vs non existence. Money is the reason why many sites are GMOs. If they had the money to convert them, they would've but since they don't they have to make due....
  16. It's called triband antennas. Many older installations, such as your region, utilized 10 port models which support 800/1.9/2.5 to replace older NV dual band hex ports. Newer deployments typically utilize the 16 port triband antennas or an addition of a dual band 800/2.5 10 port antenna. The new poles they're adding indicate they're site prepping for likely a new antenna add of some sort.
  17. There are no clear photographs of these equipment next to existing gear... unfortunately. Could not find dimensions but if we look at the publicly available photos we can get a good estimate since they're all about the same size. In comparison, standard 8T8R is ~5' tall and standard 10 port / triband / deca hex etc are around 6-7' tall while MMRs are significantly smaller compared to adult males. so I take it 3' or so?

    [PSA] Sprint begins Band 13 deployment in Puerto Rico

    A spectrum squatter owns the 800 MHz spectrum in PR / VI.
  19. by Tim Yu Sprint 4G Rollout Updates Monday, August 18, 2014 - 8:14 AM MDT [update] Sprint has announced the Sharp Aquos Crystal which confirms our findings and theories this certified device is indeed the Sharp Aquos Crystal. While rummaging through recent FCC OET (Office of Engineering and Technology) authorizations on a hot evening in late July, S4GRU staff noticed a curious new entry. It was a smartphone that supports the full spectrum of tri band LTE for Sprint Spark and, of course, CDMA2000 capabilities for native and roaming CDMA1X/EV-DO networks. However, tri band LTE has become commonplace among Sprint handsets over the past year. That was not the interesting part. Rather, what was most intriguing about this entry was the manufacturer: SHARP CORPORATION. Sharp, as a cell phone maker, is almost non existent in the North American market. Sharp doesn't even come across the public's mind when people think of an Android smartphone, but here it was -- confusing and exciting at the same time. S4GRU staff raised numerous questions and theories on what exact device it was until just a few hours ago when Sharp, along with SoftBank JPN, announced the Aquos Crystal smartphone in Japan. Additionally, tomorrow August 19th in New York, Sprint is holding a "Take the Edge Off" event, which S4GRU has been covering in The Forums since around the time of the FCC OET filing discovery late last month. How could both developments not be connected? The FCC authorization documents for this Sharp smartphone show a cross section diagram and diagonal of 14.5 cm that measure extremely close to that of the 5.0" display model, making it highly likely that this mystery Sharp smartphone is indeed the recently announced Aquos Crystal smartphone. The Japanese version is being released on August 29th. Below are its specs: Dimensions: 67 mm x 131 mm x 10 mm Weight: 140 g OS: Android 4.4.2 SoC: MSM8926 1.2 GHz (Qualcomm Snapdragon 400 quad core) Display: 1280 x 720 (LCD) ROM: 8 GB, expandable to 128 GB (mSDXC) RAM: 1.5 GB NFC compatible SoftBank LTE FDD * AXGP (i.e. LTE TDD band 41) For the Sprint variant, the FCC OET docs make no mention of hardware (e.g. processor, display, memory), as that is not the RF purview of the FCC. But the hardware specs are likely to be the same as those of Japanese version, the primary differences being the band/band class support for Sprint. And below is a cursory look at the Sprint variant maximum ERP/EIRP figures: LTE FDD band 25 (LTE 1900): 25.82 dBm LTE FDD band 26 (LTE 800): 19.72 dBm LTE TDD band 41 (TD-LTE 2600): 25.43 dBm CDMA2000 band class 0 (CDMA1X/EV-DO 850): 18.62 dBm CDMA2000 band class 1 (CDMA1X/EV-DO 1900): 23.28 dBm CDMA2000 band class 10 (CDMA1X/EV-DO 800): 18.98 dBm It's nice to see Sharp coming back into the game in the North American market, and what better way to do so then by taking the edge off and using it to cut into the competition.

    Teaser: Hello Moto (X)?

    by Tim Yu Sprint 4G Rollout Updates Wednesday, July 8, 2015 - 08:51 AM MDT Mid summer has arrived in the northern hemisphere, and that means the harvest of fall flagship handsets is just getting underway. (The exception are Apples, which are planted and picked all in one afternoon in September.) The past two weeks brought our first crop. A new authorization for a Motorola device in the FCC OET (Office of Engineering and Technology) database arrived yesterday. Just about in time for Motorola's expected August/September launch of its flagship (read: Moto X) devices. Prior to that, S4GRU staff discovered a Motorola device filing last week with FCC ID IHDT56UC2, approved for LTE bands 2/4/5/7/12/17/25/29/41 in addition to the standard W-CDMA and GSM bands. Quick staff analysis of the filing lead to the conclusion that it was a either a fully unlocked version or a T-Mobile variant -- due to onboard VoWi-Fi and intra band band 4 carrier aggregation, both of which T-Mobile is pushing hard. But other tech media discovered and wrote articles on the handset filing -- with some speculating that it was for Sprint as well, due to the inclusion of LTE bands 25/41. Did they overlook that band 26 and any CDMA2000 capability were absent? We know very well that Sprint devices must have LTE bands 25/26/41 and CDMA2000 band classes 0/1/10 at the minimum. So, we waited with watchful eye for any new authorizations from Motorola, expecting a Sprint variant soon. Indeed, Motorola delivered FCC ID IHDT56UC1. Fully Sprint CCA/RRPP and VZW/AT&T/T-Mobile compatible This handset is fully certified for the Sprint network and those of its CCA/RRPP partners. It also completely covers VZW and T-Mobile network capabilities, mostly for AT&T, too, though lacking Ma Bell's emerging LTE bands 29/30. For a full rundown, it supports: LTE bands: 2 / 4 / 5 / 7 / 12 / 13 / 17 / 25 / 26 / 41 CDMA Band Class: 0 / 1 / 10 W-CDMA Band: 2 / 4 / 5 GSM: 850 / 1900 So, Sprint Spark? Got it. VZW XLTE? Got it. T-Mobile band 12? Got it. This handset does almost everything -- including carrier aggregation. Sprint Band 41 Carrier Aggregation Capable The device is a category 6 UE and supports all of the myriad FDD carrier aggregation combos present in the unlocked or T-Mobile variant detailed earlier. But this variant also includes Sprint's LTE Advanced implementation of TDD carrier aggregation on band 41 -- aka 2x CA band 41 or B41+B41. For reference, S4GRU confirmed activation of carrier aggregation and wrote about it a few weeks ago. Now, this is the seventh announced device to support Sprint's band 41 carrier aggregation, joining the ranks of the Samsung Galaxy S6, Samsung Galaxy S6 Edge, Samsung Galaxy Note Edge, HTC One M9, LG G Flex 2, and LG G4. Edit: There may be issues with MXPE's B41 carrier aggregation compatibility with the Sprint Network. To wrap things up, I am not conclusively declaring that this is the 2015 Moto X nor that it is definitively headed to Sprint postpaid -- we all know what happened with the Sprint variant 2014 Moto X. But the band 41 carrier aggregation support screams Sprint and the FCC authorization timing comes spot on for an August/September device launch, as historically has been the time when Motorola has launched its flagship devices. So, you be the judge... Source: FCC
  21. by Tim Yu Sprint 4G Rollout Updates Wednesday, July 15, 2015 - 3:17 PM MDT Consider this just a public service announcement. Sprint Spark Band 41 Carrier Aggregation (2x CA) now is officially live according to a Sprint internal announcement leaked on Reddit today by a verified Sprint employee in the Sprint subreddit. Late last month, S4GRU found evidence of 2x CA being live in Atlanta, but this now is a formal notice that Sprint has sent to its employees. This is the present lineup of 2x CA capable devices: Samsung Galaxy S6 Samsung Galaxy S6 Edge Samsung Galaxy Note Edge LG G Flex 2 LG G4 HTC One M9 ZTE Hot Spot Edit: S4GRU has been fielding numerous questions on other devices. To make this very clear, the above are the only devices right now capable of 2xB41 Carrier Aggregation because they have the hardware (category 6 modem) that is required. Any other phones that were released previously are not compatible because their modems are not category 6 (or higher). As detailed in the internal document (posted below), the seven devices may receive automatic profile updates this week to enable 2x CA. Alternatively, as some S4GRU users have discovered, 2x CA may already be enabled or can be enabled manually via the hidden Data programming screen. Next, these are the initial markets in which Sprint is rolling out 2x CA: Boston New Jersey Long Island Philadelphia Metro Providence Southern Connecticut Baltimore Cincinnati Columbus East Michigan West Michigan Indianapolis Washington DC Austin Dallas Fort Worth Houston Kansas Missouri San Antonia Atlanta / Athens Miami / West Palm Orlando South West Florida Tampa Chicago Colorado Milwaukee Minnesota Oregon / SW Washington West Washington Utah LA Metro Las Vegas North LA Orange County Riverside / San Bernardino San Diego SF Bay South Bay For reference, here is a S4GRU map of all Sprint markets: Finally, this is the internal document posted on Reddit: Source(s): Reddit

    Even More Guardians of the Samsung Galaxy

    by Tim Yu and Andrew J. Shepherd Sprint 4G Rollout Updates Wednesday, July 22, 2015 - 1:20 PM MDT On the heels of the first of the late summer/early fall flagship handsets that S4GRU reported on two weeks ago, a second group of superheroes has appeared. And both of these new handsets are destined to be the size of a galaxy. So, take note, and stay on the edge of your seats. Last week, Samsung started certifying what is presumably its next go round of devices for US wireless operators -- the Galaxy Note 5 and the Galaxy S6 Edge+ -- with variants pointed toward T-Mobile, AT&T, Verizon, and USCC popping up in the FCC OET (Office of Engineering and Technology) database. Yesterday, Sprint's models joined the FCC authorizations of the rest under the FCC IDs A3LSMN920P, which expectedly is the Galaxy Note 5, and A3LSMG928P, which presumably is the Galaxy S6 Edge+. A quick glance at the RF Exposure reports identifies the supported LTE bands: Band 2 (PCS A-F) Band 4 (AWS) Band 5 (CLR 850) Band 12 (Lower 700 A-C) Band 25 (PCS A-G) Band 26 (ESMR 800 + CLR 850) Band 41 (BRS/EBS 2600) ...along with the standard CDMA band classes: Band Class 0 Band Class 1 Band Class 10 ...and GSM/W-CDMA bands: GSM 850/1900 W-CDMA Bands 2/5 World roaming capability -- including GSM 900/1800 and W-CDMA band 1, possibly other W-CDMA and/or LTE bands, too -- is likely on board. But FCC OET authorizations are not required to document non US bands. Carrier Aggregation Is A Go Following the the presumed 2015 Motorola X flagship authorization a few weeks back -- and that was the the 7th Sprint device to be officially certified for B41 2x Carrier Aggregation (2x CA) -- these two Samsung Galaxy handsets will be the 8th and 9th devices to be officially certified for 2x CA. All join the ranks of the Samsung Galaxy Note Edge, Samsung Galaxy S6, Samsung Galaxy S6 Edge, LG G Flex 2, LG G4, and HTC One M9. Some, though, may be disappointed that the two Samsung devices were not certified for 3x CA like the GSM/W-CDMA/LTE model for T-Mobile and AT&T, while the other CDMA carrier variants for Verizon and USCC are only certified for 2x CA as well. So, it is likely Samsung had to switch out the baseband modem for a Qualcomm category 6 one for CDMA compatibility -- whereas Samsung may have opted for its own category 9 modem in the GSM/W-CDMA/LTE models. Now, to add some RF ERP/EIRP analysis from S4GRU's technical editor... We will dive straight in to the numbers. Of course, all of the usual disclaimers about lab testing versus real world performance and uplink versus downlink apply. The figures represent our best averaged and rounded estimates of maximum uplink ERP/EIRP -- with band class 10, band 25, band 26, and band 41 receiving heavier weighting toward uniquely Sprint frequencies or configurations. Samsung Galaxy Note 5: Band class 0/10: 21 dBm Band class 1: 19-20 dBm Band 2/25: 18-21 dBm Band 4: 21 dBm Band 5/26: 17-20 dBm Band 12: 16 dBm Band 41: 17-18 dBm Samsung Galaxy S6 Edge+: Band class 0/10: 22 dBm Band class 1: 22-24 dBm Band 2/25: 19-22 dBm Band 4: 20-22 dBm Band 5/26: 21-22 dBm Band 12: 21 dBm Band 41: 18 dBm For comparison, here are the ERP/EIRP figures from S4GRU's FCC OET Galaxy S6 article a few months ago... Frankly, Samsung used to be a leader in RF performance but is showing some continued regression. The Galaxy S6 and Galaxy S6 Edge in their Sprint variants brought roughly average to below average RF. In particular, band 41 EIRP was weak. That has not changed with these two new Galaxy handsets -- band 41 is still well below the at least 23 dBm that we would like to see. Between the two handsets, the Galaxy Note 5 is the RF chump. Sorry, Galaxy Note fans, the Galaxy S6 Edge+ is notably superior in that regard. The Galaxy Note 5 ERP/EIRP is average to below average across the board. Meanwhile, the Galaxy S6 Edge+ is generally a few dB better and actually brings some good low band performance to the table. To reiterate, though, both lack band 41 oomph, and that is a disappointment for Sprint. Next, to echo Tim's sentiments above, the Galaxy Note 5 will not be the first Sprint handset to offer 3x CA capability, though many had predicted that. Both it and the Galaxy S6 Edge+ are using not a category 9 or 10 baseband but a category 6 baseband, most likely the Snapdragon X7 LTE (MDM9635) -- the same as in the Sprint variant Galaxy S6 and Galaxy S6 Edge. This is because Samsung has at least temporarily, probably permanently shifted away from Qualcomm chipsets in favor of in house chipsets. That means Exynos processors and modems. The Exynos processor is airlink technology agnostic, but the modem certainly is not. And Samsung does not have a 3GPP2 (i.e. CDMA2000) baseband, so it still sources that separate chipset from Qualcomm. For further reading on the processor, baseband, RF transceiver, and carrier aggregation issues, see S4GRU's previous FCC OET articles on the Galaxy S6, Galaxy S6 Edge, and One M9 as well as the G4. Well, that is a wrap. So, are these new Samsung Galaxy handsets Groot or not? Discuss. Source: FCC
