      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.

      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.

      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.

      3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.

      hello everyone i m starting a thread for sprint network predictions for 2018. i am wishing sprint and s4gru a happy holidays and new years.

    • M2M build time; new Raspberry Pi3b+ came in today! AC wifi, Bluetooth 4.2 and low power. Ethernet still runs over the USB interface so tops at 330 but better than the 100 fast on previous builds. I have to plug it in to my M.2 LTE radio to see if I can get top speeds. We have one Triband antenna site (total D: ) in our CMA that has progressively improved from just a few days ago to my first 100+ test evAr! on the n6P, and in our market.

      What are other users machine to machine or um, IoT projects and what are your results on the Sprint network? I have a few locations running these for connectivity, security and A/V operations over cellular and/or load balanced DOCSIS 2.0 with some edge routers, one location has fiber as main, a couple are all LTE/WIFI. Band 41 is new and brave here market wide, but great where it is so we use a mix of carriers.

      What are your experiences with plans? I simply purchase as many lines as I need and do the work to make them work with whatever network works best where I have to setup and do my work. I have seen some low power/low data plans for battery devices and such, seems like a way to prime subscribers, but they can just keep selling me UDP's and we are all happy.

      Any one use the Magic Box to help power projects? I have seen Boxes relay to hotspots, we made one directional beam from yagis, ductwork and punished a 2.5 wave through a forest for LTE push to talk between 4 users. Super users could attach apps to an LTE radio or use a phone to open doors or kick on a camera! Imagine if Gramma rolls in and Her Chair meets her at the door when her mac id hits your load balancing with the magic box? You just won the family picnic son. I tore mine down (like a dick, don't do this) put it in the car, in our attic, on a pole, and next week in the air. 

      What do your projects work towards? Long time listeners will note LTE connectivity is our main bag here in the not so sticks, we like some netsec, and putting in the time will yield a device that is convenient yet doesn't serve you ads based on surrounding conversation, search content and >9000 metadata fed into some Dale Gribble based conglomonstrosity. 



      Bonus:  Your previous content has been restored. I love this feature when I x when I should have not. 2012 Belusnecropolis appreciates this and donates 2018 accordingly.
    • All of those configurations in my Market seem to be Verizon
    • If sprint is planning to cover most of the other 50% of sites with tri band this year. Starting in April sprint will have a lot of work to do for the remainder of the year .. haven't seen to many reporting new coverage/ upgrades early on. Was sprint really waiting for the new capex to kick in ?   Sent from my SM-G965U using Tapatalk        
    • I have, S9+ is superior in every way.
