I think it would be great if Sprint could pick some spectrum in the CBRS band—I could definitely see their NR network being primarily 2.5/3.5 GHz. Additionally, if CBRS spectrum were used for NR with massive MIMO, it would be a good overlay for the L1900 grid as it would have comparable coverage/range. 

Your point about roaming is definitely true too. It would be nice for us to roam in other countries on the same band as back home; additionally, with spectrum that lines up with international providers, Sprint may be able to break into the US international roaming market (which AT&T and T-Mobile primarily dominate today).

As it is, it’s time for Sprint to be active in spectrum auctions again. mmWave and CBRS are all needed.

In the interview that Sprint's new CFO did today, he said that Sprint is content with what it has right now and doesn't see itself buying mmWave but if spectrum comes up for auction (non mmWave), Sprint will consider it. I think that's good news!

Hmm...spectrum that could come up for auction that isn’t mmWave...wonder what that could be ?…

According to FierceWireless Ajit Pai mentioned earlier this year that he is trying to auction off 28Ghz spectrum this November and that in the coming months he "intends to propose the next steps needed to make the 3.7 to 4.2 GHz band available for commercial terrestrial use"

Isn’t Sprint faster in Chicago? I have friends up there and they seem to be saying Sprint has been faster there for a while.

Sorry about my late reply. My online reading S4GRU has been very limited the past few months.

Sprint has been advertising using Schaumburg in their Chicago speed test examples. While I'm sure Sprint service in Schaumburg has improved throughout the past few years since I had Sprint, I was very impressed by it in Schaumburg back then, just not so much in some other areas. By now it looks like Sprint is doing really well around here, which is good.

All of these speedtests by all of these carriers are great. What I am looking for is consistent coverage and consistent speeds. It does not help me if in one spot it's 150Mbits and then in another 3G. I would be perfectly happy if it was consistently between 10-20Mbits throughout the coverage area.

T-Mobile just upgraded the only stealth site in town and gave it tri band lte...4X4 MIMO and 256 QAM...the signal at the coverage edge is a bit dirty but it works none the less.

What's the problem?

Those speeds are making me envious lol. We are still waiting on a site they've been meaning to build for quite sometime, till then we can't expect those nice speeds.

Well the speeds aren't like that all over town and it's really only at night when the network is unloaded

Well at times we can reach 20 between midnight and 6am. Other areas do pretty good despite the spectrum constraints in the Cincinnati market.

Yes I understand where you're coming from is only 55 mega Hertz total over here

Once they flip the switch on our 5mhz of B66 here in the area(which I hope it's soon) it should help.

TMobile has come a very long way here but they still have a long way to go and terms of coverage and actual overall signal strength.

https://www.pcmag.com/news/360673/t-mobile-5g-wont-start-out-much-faster-than-4g

This sums up T-Mobile’s 5G Deployment Issue:

According to Karri Kuoppamaki, T-Mobile's VP of radio network technology development and strategy, higher-frequency millimeter wave spectrum only has cells about 900 feet wide, though Verizon's chief network officer Nicola Palmer said last year that they can get gigabit speeds at 2,000 feet from a cell.

_______

So that’s a 900 foot cell radius which comes out to 0.1 square miles. The continental US is over 3 million square miles. T-Mobile’s 600MHz network doesn’t have the carrying capacity for true 5G speeds so it will need to supplement with millimeter wave in high-speed hotspots.... and the economics for a wide deployment of that are hard to justify.

VS.

Dr. Saw previously said this about Millimeter Wave:

https://www.lightreading.com/mobile/5g/sprint-says-no-to-mmwave-yes-to-mobile-5g/d/d-id/739592

Sprint's CTO said Wednesday that he is not sure that using millimeter waves to deliver 5G services is a practical economic use of the high-band spectrum and that Sprint will be focusing on using its existing bandwidth to deploy 5G, at least initially.

_________

Dr. Saw’s specific quotes:

"What is the cost to deliver a bit over millimeter waves? Where is the business case on that?" John Saw asked at the Citi conference in Las Vegas.

and

"We need to solve the cost challenges before you can scale millimeter wave," Saw said.

He did say that mmWave could be useful as a hotspot "overlay" to a lower band 5G network, but he added that "the laws of physics say it won't propagate very far."

Another interesting bit from that PCMag article is this;

Quote

But the value in low-band 5G isn't its initial state; it's the ramp-up. 5G technology has a lot more room to grow than 4G, even if it's starting out just a bit ahead of current speeds.

"Initially, we didn't see gigabit speeds on LTE; we saw very low speeds. But today we see much higher than that. It's kind of irrelevant what [the speed] number is going to be on day one, as it will improve over time," Kuoppamaki said.

T-Mobile can't provide gigabit speeds on 600MHz alone whereas they can on LTE through CA and numerous technologies. Sprint can achieve gigabit speeds on both 5G-NR and LTE at the same time using Band 41. That's a huge advantage and Sprint should focus on playing up that advantage and increasing density quickly so that most cities, suburbs, and even some exurbs are blanketed in Band 41.

Sprint’s PR/Comms shop needs to be on the ball here.

T-Mobile has become better around here since the initial introduction of BingeOn and the all-unlimited plans. However still not excellent quite yet. I've had some issues at an outdoor mall I've gone to a few times recently, but I'm not sure its necessarily the network. I definitely need a new phone - waiting for the Sony XZ2 Premium, so it may be the limitations of the Microsoft Lumia 950xl I'm still using, grudgingly.

      Fierce has a poll posted... and is utilizing a bracket style contest to find out who their readers think is the most powerful person in the telecom industry. Between Marcelo and the pink clad Chihuahua of a man... I give it to Marcelo. I think the final winner should be Masa, it's is a name people know and will get to know more in the coming years worldwide. But for the current poll, it's an easy decision for me!

      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.
       
      Basic Ericsson AIR21 setup
      (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.

      With the introduction of the new plans Sprint has announced. I told one of my friends about the $60 unlimited plan and she was shocked yet happy about it. She currently has T-Mobile and there has been times where my Sprint service has out performed her service even in the city with puling up information and out of town...well... you already know how that went. She was talking about switching and stuff but then she sent me a typical article bashing Sprint and I got irritated by it and I had to explain to her that Sprint is not bad at all. These articles are based on past experiences from 3+ years ago. I told her I'm pulling 60+ mbps on LTE but she's worried about Sprint being slow ( because of what she read). Guys give me some advice on persuading her to give Sprint a chance. 
       
      I feel like articles that are being posted is what keeps away customers.  It makes no sense that T-Mobiles 2g network is not spoken about when they are in the news for changes to plans and such. But good ol Sprint makes changes and articles that get posted rips Sprint apart for filth.

      Roger Cheng @cnet appears to have had the most fun out of this, it kind of wrote the story for him I guess, so there is that. Also, just noticed the extra title Q, that is gonna drive some people nuts today. Top lel.

    • I chatted with a foreman the other day (figured out what tmo panels look like lol) but he was also "on lend" from a verizon contractor. So he didn't know a ton.. but enough. It's going on, it seems like its a little bit of slow process. And things screw up there to (he had an install were the panels S/N didn't match that which was on the paper work back in the office)   AND TMO does more over the phone vs having a eng. on hand like verizon does, so it slows it down a bit if they have a hiccup... Like wrong S/N lol
    • The direct number to Account Services/Retentions is  844-382-3317 . I think they might be able to help.
    • I went to three stores that had Sprint SIMs in stock, none of which could activate one for my iPhone. I also tried calling in twice as well as speaking with someone on online chat. In every instance, I was told they couldn’t move me back or that the system wasn’t letting them activate my device. While it may be possible to go back, they are definitely not making it easy. And customers like me (who depend on their phones for work) cannot deal with dropped calls and EDGE in the time it takes to figure it out. 
    • Unless something has changed, you can still go back. There are still immediate needs to do so- activating a phone not eligible for TNX yet like a pixel 5 for instance. You just have to do it through chat/customer support as the online portal doesn't support going back to a Sprint sim.
    • Just a heads up for anyone else thinking about making the switch to TNX - I tried for about two weeks and it does not appear you can go back if you don’t like your service with TNX.  I would strongly recommend staying on TNA for anyone who is hesitant/unsure.
