  1. Tim YuSprint 4G Rollout UpdatesJanuary 12, 2018 - 5:30 PM PST "New year, new me. Am I right?" ~ signed Samsung Samsung has decided that the beginning of the new year is a great time to change. Samsung has decided its newest flagship Galaxy S9 and S9 Plus devices must meet with the FCC OET for certification far earlier than usual. With ever watchful and prying eyes, S4GRU staff discovered the twin filings for two devices with FCC IDs of A3LSMG960U and A3LSMG965U which follows the previous Samsung numeration of the Galaxy S8 / 8+ (950u/955u) and Galaxy S7 (930u/935u) respectively. In addition, previous leaks for purported international Galaxy S9 variant have captured the ID of 960F and 965F respectively. To keep this short and simple, the Galaxy S9, to date, is the most technologically powerful device we've seen at least for Sprint and possibly other entities and the following technical specifications should demonstrate why. CDMA BC: 0 / 1 / 10 GSM: 850 / 1900 WCDMA Bands: 2, 4 , 5 LTE Band: 2, 4, 5, 7, 12, 13, 14, 17, 25 , 26 , 29, 30, 38, 41, 66, 71 Downlink Carrier Aggregation (DL CA) 5xB41 (up to 5 B41 carriers aggregated) B25+41CA (up to 2 B41 carriers - 3 total carriers aggregated ) B26+41CA (up to 2 B41 carriers - 3 total carriers aggregated ) B25+26CA (up to 2 B25 carriers - 3 total carriers aggregated ) Uplink Carrier Aggregation (UL CA) 2xB41 256 / 64 QAM Downlink/ Uplink HPUE CAT 18 Modem 4x4 MIMO B2, 4, 25, 30 , 41, 66 12 spatial streams Holy bonanza! This phone supports up to 100 MHz of LTE spectrum being aggregated together from 5 individual Band 41 carriers! To add to that, it also supports FDD and TDD LTE carrier aggregation by utilizing Band 25 1900 MHz or Band 26 800 MHz as the primary component carrier which would contribute to downlink and uplink while Band 41 is aggregated to it would be downlink only secondary component carriers. Remember the saying of having B25 or B26 uplink with Band 41 downlink, anybody? Plus there is expansion of FDD carrier aggregation to that of between Band 25 and Band 26. This will help a ton in areas where Band 41 and its oodles of capacity does not reach. As the recent CDMA refarming nationwide on PCS spectrum has allowed Sprint to fire up an additional Band 25 carrier, this means in many Sprint markets there currently exists two Band 25 carriers in addition to a Band 26 carrier. This additional carrier is not forgotten and can now be used alongside the other Band 25 and Band 26 carrier for carrier aggregation. Last but not least, this phone is "Gigabit Class" by having up to 12 spacial streams means that 4x4 MIMO can be used for 3 separate B41 carriers when aggregated together instead of 2 in the previous generation which supports only 10 spacial streams. Though it was a moot point as the entire generation of Samsung flagships from this past year did not support 4x4 MIMO on Band 41, until now! A phone this size should not be able to pack so many technologies...but yet it does! A splendid phone and surely a must have for the S4GRU and other tech adept users!

    What's in the Box? Oh, oh, oh, it's Magic.

    Tim Yu Sprint 4G Rollout Updates May 19, 2017 - 8:30 AM PDT The Sprint Magic Box was announced on Sprint's quarterly earning call earlier this month, and was heralded as the first truly all wireless small cell in the industry. So what is this mystical beast that is purported to increase coverage by up to 30,000 square feet, amplifies data speeds, and "boosts" your data signal? This is the 1st Generation Sprint Magic Box In more technical terms, the Magic Box is an Airspan product under their Airunity line. The black colored model that exists in the wild, and which I procured contains the Airspan Airunity 540 small cell eNB. Whereas the white colored Magic Box advertised by Sprint is a newer model that contains the Airspan Airunity 545 small cell eNB. The primarily difference is that the unreleased white Magic Box is able to broadcast at twice the transmit power compared to the black model which results in substantially increased coverage area in addition to the LTE UE Relay Module having HPUE capability. These are all wireless small cells as there is no requirement of a wired backhaul solution like traditional Femto cells like the pending Sprint Airave 3 LTE, Commscope S1000, or the T-mobile LTE Cellspot. Instead, the Magic Box (MB) utilizes a technology called LTE UE Relay that is integrated into the overall package. The Magic Box contains an Airunity LTE B41 2500 MHz small cell and a LTE UE Relay device called the ninja module whose only job is to establish a data link to a macro eNB LTE 1900 or 2500 MHz signal and then feed a data connection to the Airunity small cell. For more on LTE UE Relay: see here Once the Relay link is connected and data flows to the Airunity eNB, a new LTE 2500 MHz signal is then created and broadcasted from the unit. This signal is unique to the Magic Box and is available to use by any compatible Sprint device that can access the LTE Plus (2500 MHz LTE B41) network. Unlike a repeater setup, the Magic Box does not simply take an existing signal and amplify it and all the accompanying noise and interference. This is a brand new and very clean LTE signal being broadcasted. The following screenshot from Network Signal Guru app displays this clearly. The Magic Box in my location broadcasts a brand new LTE carrier with frequency located on EARFCN 40270 (2558 MHz) while the macro donor eNB signal of 40978 (2628 MHz) is used as backhaul (LTE Band 25 1900 MHz can also be used). [As of July 2017, the Magic Box had its LTE carrier center frequency switched to 2518.4 MHz or EARFCN 39874. Signal Check Pro screenshot] This means, instead of a weak edge of cell LTE signal with the accompanying band switching that substantially impact device stand by times and I may lose deep inside the building, a Magic Box allows a Sprint device to connect to a strong and clean LTE 2500 MHz signal which blankets the formerly weak LTE coverage area. As a side effect, LTE speeds may also be dramatically increased due to the better signal level and quality being broadcasted by the MB whose LTE Relay Module can connect to what may have been previously an unusable 2500 MHz network. Especially when placed by a window as recommended. Album of Screenshots Personal Experience In my more than one month of observations using the Magic Box, I was able to connect to a LTE 2500 MHz signal from inside a suburban family residential building where such a signal was previously unusable. Furthermore, not only did the Magic Box boost the data signal from weak edge of cell service with consistent frequency swapping that had previously killed our devices battery life, but it also increased the LTE data speeds substantially to the tune of 200-300% over what we were previously getting over LTE 800 and 1900 MHz. Whereas previously the house was a weak coverage area where LTE 800 MHz was predominant with even parts dropping to EVDO 3G, the new LTE signal broadcasted by the MB covers the entire house and then some through multiple interior walls and even an exterior brick wall before handing over back to the macro network. So what's my view on the Magic Box? It can't come soon™ enough for more people to use and enjoy.
  5. Tim YuSprint 4G Rollout UpdatesDecember 11, 2017 - 9:30 PM PST Recently, individuals who ordered Magic Boxes noticed a change in the product code of the unit to AU544 from AU545. It is now confirmed that the product code change is due to the release of the 3rd generation Magic Box. They are now being shipped! The new revision is in essence a GEN2 optimized with a high quality LCD touchscreen display like that of the 1st Generation AU540. In addition, an external battery pack with an adapter to hook onto the Magic Box is now provided. It can be lugged around for testing purposes instead of internal batteries. In addition, the touch power on button of the GEN2 has been removed with power on sequence done by plugging in power to the unit via a battery pack with an adapter or via the AC power brick. Performance wise, the GEN 3 is identical to the GEN 2 in that they still utilize the Airspan Airunity 545 small cell eNB and a Ninja LTE Relay module. The product designation change from 545 to 544 is primarily due to a change in the WiFi module to a different Qualcomm WiFi module. But for what matters to Sprint users, the LTE B41 performance impact as noted from GEN 1 and subsequently the GEN 2 are identical. GEN 2 users will not be left behind in performance wise. Previous generation device owners will not be missing out on much! For those that are getting the Magic Box for the first time, welcome to the party!

    The Magic Box 6 months later

    Tim Yu Sprint 4G Rollout Updates September 28, 2017 - 2:30 PM PDT [Edit: 4/6/18: Reflects Airave 3 discontinuation] It has been 6 months since I first learned of and received access to what is now called the GEN1 Magic Box. I wrote up my thoughts about it a few months back. Sprint has now evolved to a GEN 2 Magic Box model. These units are being distributed to customers who preordered after Sprint's announcements. I've now acquired a GEN2 Magic Box myself. Upon opening the package, the most immediate and noticeable difference between the Gen 1 and Gen 2 Magic Box is the absence of an external portable battery. This was useful to lug the Magic Box around and test different locations in order to select the best spot for unit placement. On the surface this may appear to be a way to decrease unit costs. This may be true, but the Gen 2 model contains two CR18650 rechargeable lithium batteries integrated inside of the package for the same purpose. No more using a dongle and a hefty battery pack that could be easily lost! [2nd Generation Magic Box white colored on left, 1st Generation Magic Box black colored on right[ Along with the new internal guts, the external aesthetics and materials were also modified. The Gen 1 model had a super bright LCD display with a black front surrounding by white plastic. The new Gen 2 model has an eInk display with a touch power button below it on the front with the entire exterior being a reflective polished hard plastic. What didn't change is the GEN2 is still an all wireless small cell with no requirement of hard wired backhaul supplied by the user. It still uses LTE UE Relay to acquire an existing Band 25 1900 MHz or Band 41 2500 MHz connection from an existing donor site, which is then fed to the small cell unit and broadcasted as a new LTE Band 41 2500 MHz carrier. The LTE Relay unit supports up to 2 carrier aggregation on Band 41 to the macro donor site. Now to the meaty parts. The performance. Let these screenshots tell the story. Before After [Apps used: Network Signal Guru, Signalcheck Pro, Ookla Speedtest] The extremely significant data speed and signal improvements that were experienced by the original Magic Box still exist with the 2nd generation unit. The GEN2 matches and exceeds the performance of my original Magic Box, especially in the upload category. This is due to the newer LTE Relay module design which utilizes a higher gain antenna. A very satisfactory model upgrade. It upholds the positive impressions I outlined in my original article. These units just can't come out fast enough so that more people can enjoy it! The Magic Box is not a panacea, but is a very good solution in many locations. Now that thousands of these preordered boxes are hitting the streets in countless different deployment scenarios, lots of limitations and bugs are being discovered. With varying impacts. The Magic Box doesn't work for everyone everywhere due to the very nature of its all wireless design. In most places, it works as advertised. Just power up and let it rip. In a few locations there is something lacking which causes units to not fully configure. This results in errors such as the infamous "20% initialization" or "cannot connect to mobile network" screens that pop up. We researched, asked questions and were informed that Sprint's LTE Relay configuration is of the out of band variety. This means that the LTE UE Relay operation and the small cell eNB signal has to operate on different frequencies. So in Sprint's case, a market must have Band 41 High and Low separation in order for a LTE Relay to work. Thus, Sprint must have spectrum in the Band 41 low range (2500-2570 MHz) and the Band 41 high range (2620-2690). If a Sprint market does not have said spectrum with such a separation, the relay link cannot be established and the Magic Box will not work. In markets where such spectrum peculiarities exist and areas where the macro 1.9 GHz and 2.5 GHz RF signal is not strong enough to establish a LTE Relay backhaul connection for the Magic Box, there exists other alternatives available from Sprint. These alternatives are the Airave 3 LTE and Commscope S1000 NSC which will be offered to subscribers who do not qualify for a Magic Box or in a location where the Magic Box does not work. The subscriber will require a home broadband connection in those instances. (Left: Airave 3 LTE, Right: S1000 NSC; credit: ingenium & pwnedkiller) The Airave 3 LTE is the traditional CDMA + LTE Band 41 + WiFi femto cell. It is the successor the Airaves of old. The Commscope S1000 NSC is a LTE Band 41 + WiFi only femto cell which is in essence the Airave 3 minus the CDMA capabilities. If a subscriber desires voice and data enhancement then the Airave 3 should be what the subscriber seeks. If the subscriber does not need voice enhancement due to sufficient macro voice coverage but need 4G LTE data enhancement, then the S1000 NSC would be a better fit. There is a solution for just about everyone now. There now exists an all wireless self configuring LTE small cell, a state of the art and award winning LTE small cell, and which when paired with a CDMA module produces the newest successor in the Airave family. All of which will bring extreme improvements that Sprint subscribers can realize instantly. The densification of Sprint's network is now beginning and it all begins with one quite magic(al) box.

  7. 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.***
  8. 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!

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.
  13. 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.
  14. 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....

    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.
  18. lilotimz


    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...
  19. I mean end of year 2018 is getting awfully close...
  20. Zis -->> http://s4gru.com/entry/428-discovery-time-next-gen-dual-band-10-port-800-25-configurations/
  21. 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....
  22. 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.
  23. 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?
