  1. 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.

    Sprint 10x10 B25 can easily get 10-20 mbps and a few regions where 15x15 B25 exist can do even higher. Even 5x5 can do 10-15 up depending on congestion. Sent from my Pixel using Tapatalk
  3. Or they're doing it how they initially brought up B26 in most markets where it wouldn't really be better in coverage than B25 and then later on optimized it.

    Huawei RAN is 100% decommissioned and no those equipment weren't. Their capability (2007-2010) was extremely lacking compared to the 2011-2012 era Samsung equipment Clear was deploying and the new RRU32xx series they planned to deploy but which got nixed by the Softbank - Clear - Sprint buyout. Those antennas are also passive so it'll just broadcast whatever radio is wired into it and doesn't really have a big impact on radio virtual sector splitting.

    It is very much so. The Samsung clear dual mode equipment are capable of up to 80 MHz of spectrum if the high capacity split transmit path configuration is done just like how Sprints 8T8R 2.5 is capable of 120 MHz. They basically did a software update to enable this capability and added a 3rd contiguous carrier via software en masse to add capacity to existing equipment. They'll be replaced eventually as the permits show but until then the additional capacity is well appreciated.

    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..
  8. 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.

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

    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.

    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.

    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.

  22. For clarification it's 4x4 MIMO eNB. UE is 2x2. Sent from my Pixel using Tapatalk
  23. 4x4 + 2x2 + 2x2 + 2x2 + 2x2 w/ 256 qam on 20 mhz carriers rounds out to little over 1 gb.
