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.

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.

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.

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.
Thanks in advance.
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
You don't define cheap, but the LG v30 and v40 work well, can be rooted, and can be found for pretty cheap(<$100-150). As expected, the v30 is cheaper than the v40 and I can attest the v30 works very well. That being said, it lacks bands 28, 40, and 71 and has the drawback that Sprint never released Pie for it (the only vendor who didn't). This means some of the 9.0 bandwidth features are not available for SCP, that being said NSG is able to provide this data on 8.0. Sprint LG V30+ (LS998) LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 41 Sprint Lg V40 (LM-V405UA) LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 28, 40, 41, 71
1. Wifi calling directly uses your home's wifi to place the call while the Pebble uses your internet connection to broadcast an LTE signal which your phone uses to place the call (once VoLTE is enabled). Before VoLTE is enabled, you don't place calls through the Pebble, it only boosts data. After 2-3 weeks, VoLTE should be enabled on the Pebble allowing simultaneous voice and MMS which wifi calling doesn't allow mms (but if you have a decent signal you can receive MMS without issue while on a wifi call). 2. Yes, any user can piggyback off the signal but I noticed the footprint isn't that large and didn't extend outside my home. I wouldn't be too concerned with that. 3. If you disconnect the device they will send you warnings that they will charge you if you don't reconnect it or send it back.
You can move them in the app as by long pressing on the tower and dragging it to it's new location. Sent from my LG-LS998 using Tapatalk
