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.

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.

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):
So many groups have made up their minds first, find facts to back them later. In a more straightforward article would want to see the models assumptions in detail. The article quotes Dish, whose role is typically to drive up the costs of mergers. Without Dish doing that for the purchase of Clearwire, there possibly could have been billions more for Sprint network expansion or lower prices.
I still think that the prices will be more in mind for Verizon and AT&t. Honestly to build out a maintain and expand the network of that caliber and size you need obviously more money from your revenue source which is consumers. So in these higher prices to build out the network and to maintain it it cost lots and lots and lots of money I do not see prices going lower. They would not be turning a profit they kept prices where they are.
