Samsung Network Vision equipment are highly distinct and fairly easy to spot compared to the equipment that other vendors are deploying. Sprint is Samsung's first extremely massive American contract (baring Clearwire) so there should be no issues in confusing these equipment for another carrier which happens often with Ericsson NV equipment.
Below are images of Samsung equipment which includes antennas, remote radio units, base stations, and their mounting configurations.

Sprint announced at MWC trade show in Barcelona that 5G will go live with 4 cities starting in May (Chicago, Atlanta, Dallas and Kansas City )
Sprint announced the MVNO Google Fi will use its network for 5G in a press release (that is, once there are actually 5G capable phones compatible with Google Fi someday):
This is the first I've heard about Fi and 5G so far. Google has pretty much kept mum on the topic, so I'm somewhat encouraged.

I'll clean the post up this weekend when I have more time.

When Virgin Mobile introduced their Inner Circle plan they added Extended coverage giving them the same coverage as Sprint Postpaid. And a few months ago when Virgin did away with its Inner Circle plan and its iPhone only to the current plan lineup and devices I figured they'd backtrack on the roaming and go back to Sprint only. While they may not have updated their coverage map it would seem they are not allowing roaming as my LG Tribute Dynasty which is compatible with US Cellular roaming is being restricted and blocked post activation. Before hands free activation began I was able to go into the devices network and roaming settings and switch on voice roaming, which worked, it immediately connected to US Cellular, then the hands free activation started which couldn't complete due to no data until I switched on wifi, but after the device rebooted, the voice roaming was turned off and greyed out so it couldn't be switched back on.
I know this device is capable of roaming, it has band 12 and band 5 for LTE and the CDMA band necessary to roam onto US Cellulars CDMA network, which again it was able to due prior to activation. If Virgin Mobile is going to continue having roaming as an option then it should work otherwise they need to remove it from their coverage map. I've attempted to take the issue up with Virgin but they tell me that they'll help me with any other issue, except roaming. I believe it has something to do with the PRL since it is what determines the devices roaming. I found a old Virgin device from before Inner Circle started, in it was PRL 7080 the same one as it has now, back then Virgin was the home network on Sprint only, no data or voice roaming.
I don't know where the issue is with this and I'm hoping after filing a complaint with the FCC which has been served that it is either corrected and fixed and roaming starts working, or Virgin removes it from their coverage map if they're not going to allow it. I've asked customer service if the coverage map and the roaming on it applies to current customers or if it was just Inner Circle and they say it does apply to the current plans. If so, and if I have a device that is compatible (LG Tribute Dynasty), why is it being restricted.
Yeah we get higher throughput w T-mo as well, on bands 4+2 4x4 = 60Mb p/s vs 4+2+5 2x2 =55Mb p/s. I even found and authenticated band 4/66 on AT&T, MFBI too. I have had so much trouble just connecting to it, let alone getting 15Mb p/s down. rsrp is like -120, but SNR is -14. EARFCN's 66486 @10MHz and 66661 @5MHz checking in with 4x4 MIMO.
This is a dream.
4x4 MIMO is fun! / How we learn to cope w (signal)Loss.
Tl;dr: Physically measuring each connection as you test to confirm is important. Double checking port number values and what command line values represent. This is one of the early things to add to the checkbox for us tinkerers as 4x4 becomes more accessible.
While cleaning up in the lab, I thought of something and naturally stopped to do some more work in the lab. I figured I should clean up the wiring a little more in my test box, and make room for another board, hopefully the rb11g, failover and such. I inventoried a few jumpers and connectors and found I could be a little more efficient in my setup. I added in some sma>3'>N adapters, instead of a couple more adapters I had screwed in already that kept it shorter. I am going to use those any way when I permamount this thing and add better auxiliary antennas for 4x4 MIMO, than what I have attached now.
I decided to double check my understanding of the documentation Telit provides for the LM960. Well after some reading, some at#commands as swapped 2 for 2, deciding what 0 and 1 ports on what side correlate to the first two and the last two of the 4x4 setup it, turned out I had my setup wired exactly backwards. Very inefficient, not good. I no longer have loss on my upload and is now 7x faster. I am surprised at how well my backups pulled down. I understand how useless a couple of commands were in describing what I needed.
It is even more tough when using one band that is always 4x4, but I used that to my advantage as only mains Tx and Rx. I connected and tested each variation of antenna>port. Naturally my 5 footer was best, it just had to be on the mains. Wanted to document my misunderstanding so others didn't have to, especially before it goes on a roof or up a pole. I also am much happier with performance, glad my antenna is not defective and it was fun to figure it out. Gotta sweep up. Have a great night everyone.
I’ll ask the tread. I guess as band 26 is still being optimized could there be issues on the network? My data on the I phone xs max keeps timing out in the middle of loading stuff I’ll pull 80mbps and then next second it won’t work anymore and I have to toggle airplan mode for it to work again. I had this phone replace once already. Sent from my iPhone using Tapatalk
