  1. Tim YuSprint 4G Rollout UpdatesThursday, August 2, 2018 - 12:01 PM PDT It's been a long time coming for Sprint through many trials and tribulations. Now it's finally here! S4GRU was able to obtain confirmations that Sprint is finally ready and prepared to enable Voice over LTE (VoLTE) for subscribers to manually opt into in select markets across the country this coming September. See list at the bottom. As a refresher here are some of the essential points about VoLTE applicable to Sprint: Calls placed over VoLTE will have the QOS tag unlike the current Calling Plus configuration on numerous Sprint devices Like Calling Plus, VoLTE will have no fallback to the legacy 1x voice network. Calls will drop if the LTE signal drops. The voice codec is AMR-WB which one can experience with Calling Plus calls and matches the other carriers VoLTE setups. At this point and time S4GRU does not have a list of compatible VoLTE devices though we do speculate that any device currently running Calling Plus should be able to tap into that very same IMS core Calling Plus utilizes via true VoLTE. In addition, recent Apple iPhone's seems like a sure bet as some users have already experienced VoLTE in live field tests conducted by Sprint. For the non Sprint branded BYOD devices like Google Pixels or unlocked Moto devices the future is quite murky indeed.

  2. 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.

  3. 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. Original story: http://mobile.reuters.com/article/idUSBRE8B20XC20121203?irpc=932 My opinion: Samsung is bidding lower than Ericsson on some projects and winning those bids...and deploying faster than Ericsson in some cases (e.g. NV). So Ericsson wants to stop looking slow and expensive...by slowing Samsung down and making them more expensive. I really hope that they can come to a reasonable resolution on this issue, since otherwise both Ericsson and Samsung NV builds could be slowed. And Ericsson in particular shouldn't get any slower than it already is.
  6. I know Sprint is the only carrier where we have (to my knowledge) information about which vendor is handling what part of their network, but I'm curious as to whether Verizon, AT&T and T-Mobile have similarly regionalized their next-gen network deployments. For reference, here's who's building out networks for the Big Four, plus C-Spire and MetroPCS (since we now who they're using to roll out LTE): Verizon - Ericsson, AlcaLu, NSN AT&T - Ericsson, AlcaLu Sprint - Ericsson, AlcaLu, Samsung T-Mobile - Ericsson, NSN MetroPCS - Ericsson, Samsung C-Spire - AlcaLu AlcaLu = Alcatel-Lucent NSN = Nokia Siemens Networks ...and yes, Ericsson is really busy rolling out LTE, it seems.
