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.

T-mobile Ericsson Cell Equipment
For Ericsson markets t-mobile uses what is known as AIR antenna units which have the radio unit integrated with the antenna. This type of setup significantly reduces signal loss from the radio to the antenna since they're both practically next to each other and not sepearated by coax jumper cables like that of a remote radio unit.

(Note typically there are 2 Ericsson AIR per sector)
Ericsson AIR21 + Band 12 700 mhz Equipment
Note the addition of a new low band 700 mhz capable antenna + Ericsson RRUS11 B12 (remote radio units) in addition to new TMA (tower mounted amplifiers) connected to the AIR antenna. The new Ericsson RRUS11 B12 + Antenna addition is for tmobiles band 12 700mhz (L700) deployment.

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.
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.
Marcelo Claure, Town Hall Meetings, New Family Share Pack Plan, Unlimited Individual Plan, Discussion ThreadGiven how competent Ericsson seems at developing new network equipment, I still can’t believe how bad they were at managing it as part of the Managed Services Contract it had with Sprint a while back. I guess all is forgiven now?
Marcelo Claure, Town Hall Meetings, New Family Share Pack Plan, Unlimited Individual Plan, Discussion ThreadGoing to the release that's linked in the article, you'll find this quote: "The new standalone 5G NR software can be installed on existing Ericsson Radio System hardware." Clicking the link of "Ericsson Radio System" and going about 3/4 of the way down you'll find mention of some antenna models. Sprint is currently using AIR 6468 antennas with the updated AIR 6488 antennas replacing those. Only using those models will there be a software switched upgrade
Marcelo Claure, Town Hall Meetings, New Family Share Pack Plan, Unlimited Individual Plan, Discussion ThreadVerizon is / was deploying the Ericsson 5GTF backend systems which is their proprietary 5G pre NR standards setup. The M-mimo equipment on cell towers / light poles are dual mode 5GTF and NR capable. So it's fairly simple for them to just "flip the switch" (simple terms). They had built a completely new standalone system for 5GTF that doesn't really interact with their extensive LTE EPC hence why they can go full stack NR rather than mixed which most carriers will be going with.

It implies that massive mimo is not necessary. Sent from my SM-G965U using Tapatalk
No I think 5G requires the Massive Mimo setup. Sent from my SM-G965U1 using Tapatalk
