  2. Anatomy of a Sprint Triband Hexadecaport (16 port) Antenna Setup

    It's a 10 port 8T8R 2.5 + 2T2R 800 setup. I'm writing something on that soon as well. Probably posted sometime next week..
  3. 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.***
  4. 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 RRUS11 B26 top and RRUS31 B25 bottom 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. Ericsson RRUS11 B25 [EOL'd] and B26 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. Ericsson NV high capacity site [EOL'd] 3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.

  5. I'll try and keep this as updated as possible as information becomes available. Maybe i'll find one time to do one for all of Sprints devices eventually...

    Yep that's the right one! The third BYOD Sim type (CSIM, ISIM v1, ISIM v2). Sent from my Pixel using Tapatalk
  7. The S4GRU BYOD Sim Compatibility Chart

    I'll make a spreadsheet for non BYOD devices in time. Sims are sorta "universal" if you take into considering the BYOD ones. The great reason why Sprint has so many sim variants is they're developing the sim card module as they update their network and devices. They have little experience in that category so must constantly iterate in order to take advantage of new technological developments on the handset and on the network side. We can see this move from USIMs to CSIMs and now ISIMs. S8 Active is.. CZ4114LWQ SIMOLW416Q 854798005125

    You'll need to ask for the BYOD card probably. Only like 2 popular mid range devices uses it so it's a pretty rare card to have around. Just make sure they get the card with such specified info.

  11. Example: 30-50 T-mobile employees do (better) work compared to up to 200 Sprint employees on similar projects.
  12. Hello everyone! It is the belief of myself and of the staff that it is time to reopen a new T-mobile LTE and Network discussion thread due to the implementation of "network prioritization" that tmobile is doing to its subscribers. As Sprint has similar language in its TOS, we believe that it is worthy of being discussed here as Sprint may do something similar on a site by site basis. This thread will be strictly for discussing T-mobiles LTE network and technologies and not about personalities, their followers, and etc etc which may be better suited for S4GRUs sister site for T-mobile T4GRU. As a result this thread will be heavily moderated to stay on topic but I view the S4GRU member base very favorably and trust that we won't have much problems here.

  14. Official Magic Box discussion thread

    Sprint in internal communications directly instructs their stores to not accept Magic Box returns on location and directs them to contact sprint customer support to obtain Rma kits. Sprint store employees are definitively not trained nor equipped to handle anything related to magic boxes and to recommend it as a fact will lead to headaches beyond comprehension.

    No. DO NOT DO THIS. Sprint stores cannot return or take in Magic boxes. One must request an RMA kit from Sprint tech / magic box support and ship it back to Sprint.
  16. 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 relay antennas are able to pick up much better than whatever puny thing is on mobile devices. Each antenna element is about the size of a phone. Also no modifications allowed on it as it's an certified transmitter on licensed frequencies.
  19. The Magic Box 6 months later

    Tim Yu Sprint 4G Rollout Updates September 28, 2017 - 2:30 PM PDT 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 new LTE Relay unit supports up to 3 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.
