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.
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 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.

Try to make this as short and simple as possible. I have three devices; 2 of which are on the same plan and the third on a separate plan.
The third device is my tab 4 which is picking up SprintB41 site 310120 just great. I get 3 bars downstairs.
My other two devices; Galaxy Note 4 & Galaxy Note Edge for some reason will not pick up this tower. I have tried PRL updates, Profile updates, restarted the phones and all I can get them to connect to is a ClearwireB41 site.
More background info...all devices have same Sim card as when purchased, tablet stays off 3/4 of the day and my phones are on when I wake up and turn them off at night. No matter where I go inside or out my phones won't connect to the Sprint site.
Anybody have any ideas before I call Sprint trying to figure something out? I'm not sure how long the tablet has been able to connect to this site so I'm not sure what to think of it besides agitated that the tablet of all things is connecting. I posted two photos; one of the tablet connected to the Sprint site; second of the Clear wire site my phones connect to.
Sprint appears to be redoing the B41 Coverage map on a city by city basis. Much more realistic than prior version. Slight exaggeration remains in a few local spots, but this is far far outweighed by B41 that is not shown. http://coverage.sprint.com/IMPACT.jsp?INTNAV=SJS:HE:Cov
So in my discoveries of latching onto B41 I have noticed several oddities.
Mainly speed; and those horrible pings!: image
Is this tower somehow still connected to old WiMax backhaul? (regardless of which tower I am connected to speeds are in the pits like shown above). image
I am supposed to be in a Sprint Spark Turbo market and the speeds are considerably worse than B25, B26 seems to be in testing I don't stay connected long enough to do any tests. But regardless of signal strength the speeds are generally the same on B41. Don't know if this is in the right place but I figured I would take a shot.
Anyone have info on the tower at 60 Hanover St. in Meriden? Can’t find any permit info but it after service outages yesterday afternoon, I briefly saw 5 bars of 10x10 b25 (8290)
this was an old clear only tower.
Its decent but definitely not better than 1x800. You start hearing that robotic sound and then it goes to shit from there if your around 115 b26. I have even seen it happen with 105dbm of b25.
I'm on b25 most of the time and once 10mhz showed up on most towers converge of b25 vastly improved but lately b41 has been expanding quick. We now have ten b41 towers online. Seven from just the last 90 days and one of them came online today.
