    Josh HillSprint 4G Rollout UpdatesFriday, April 5, 2019 - 3:06 AM PDT Now that VoLTE is actually rolling out on Sprint, it's a good time to dive into what exactly is VoLTE, and how is it different from Calling+ and VoWiFi (Wifi Calling). Background Terms E-UTRA or EUTRA: Stands for Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access. This is the technical name for the actual LTE airlink. QoS: Quality of Service. This is a way of tagging / flagging certain types of traffic to have priority above or below other traffic. When traffic has a QoS tag higher than other traffic, network equipment (the tower, routers, etc) will drop or ignore lower priority traffic to ensure that this traffic goes through instead. The equipment can also be configured to reserve a certain amount of bandwidth to only be used by traffic with a particular QoS tag. For example, if a router has 10 Mbps available, it can allocate 1 Mbps for a certain QoS tag. Normal traffic will only be able to use 9 Mbps, with 1 Mbps reserved for that QoS tag. The number of QoS priorities / tags varies between equipment vendors, but can be in excess of 256 priority levels. QCI: QoS Class Identifier. This is a value that an LTE / E-UTRA session can be assigned that corresponds to a particular QoS tag and specific attributes of that particular QoS queue. For example, it may or may not specify a guaranteed/dedicated bandwidth allocation (GBR). APN: The APN is the name of the gateway on a mobile network. It identifies the packet data network that should be used for that E-UTRA session. IMS: IP Multimedia Subsystem. It is a method for sending SMS over LTE, along with setting up VoLTE calls and other signaling. eCSFB: Circuit Switched Fall Back. For phones / UEs that can only listen on either LTE or CDMA rather than both simultaneously, it is a method for the LTE network to tell the device that a call is coming in, and to switch over to CDMA to process it. SRLTE: Single Radio LTE. This is a capability of newer devices that allows them to listen on both CDMA and LTE at the same time, but only transmit on one at a time. This replaces the need for eCSFB, allowing the device to see a call coming in over CDMA while it’s using LTE. It is also more reliable and reduces the number of missed calls due to failed fallback. When a call is active, the LTE session is stopped / paused. SIP: Session Initialization Protocol. This is the standard protocol for VoIP in telecom networks. How VoLTE Works While we typically think of LTE as a single connection, multiple E-UTRA “sessions” can actually be established, creating what are essentially virtual/multiple LTE interfaces, each with their own IP address, QoS level, APN, etc. Each session has a numerical QCI assigned that dictates the actual QoS priority and whether or not it has a GBR (Guaranteed Bitrate). QCI Resource Type QoS Priority Packet Delay Budget Packet Error Loss Rate Example Services 1 GBR 2 100ms 10−2 Conversational Voice 2 GBR 4 150ms 10−3 Conversational Video (Live Streaming) 3 GBR 3 50ms 10−3 Real Time Gaming, V2X messages 4 GBR 5 300ms 10−6 Non-Conversational Video (Buffered Streaming) 65 GBR 0.7 75ms 10−2 Mission Critical user plane Push To Talk voice (e.g., MCPTT) 66 GBR 2 100ms 10−2 Non-Mission-Critical user plane Push To Talk voice 75 GBR 2.5 50ms 10−2 V2X messages 5 non-GBR 1 100ms 10−6 IMS Signalling 6 non-GBR 6 300ms 10−6 Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like) 7 non-GBR 7 100ms 10−3 Voice, Video (Live Streaming), Interactive Gaming 8 non-GBR 8 300ms 10−6 Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like) 9 non-GBR 9 300ms 10−6 Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like). Typically used as default bearer 69 non-GBR 0.5 60ms 10−6 Mission Critical delay sensitive signalling (e.g., MC-PTT signalling) 70 non-GBR 5.5 200ms 10−6 Mission Critical Data (e.g. example services are the same as QCI 6/8/9) 79 non-GBR 6.5 50ms 10−2 V2X messages (source: https://en.wikipedia.org/wiki/QoS_Class_Identifier) As you can see in the above table, the QCI does not necessarily correspond to the QoS level. For example, QCI 1 has a QoS priority of 2, but QCI 5 has a QoS priority of 1, making it actually higher priority traffic. On Sprint, traditionally one E-UTRA session was used, with a QCI of 9 and QoS priority of 9. This is the lowest QoS priority, and does not have a guaranteed bitrate. On devices which use eCSFB or VoLTE, another E-UTRA session is established for the IMS APN using a QCI of 5 and QoS priority of 1, and is used for IMS. This session also does not have a guaranteed bitrate, but it has the highest QoS priority. IMS is used for SMS over LTE, along with setting up VoLTE calls. eCSFB devices use it for SMS, and likely also for triggering eCSFB. On newer device which instead use SRLTE, IMS is not used unless VoLTE is enabled, and they instead use CDMA 1x for SMS, so an IMS E-UTRA session is often not setup. When a VoLTE call is initiated, a third E-UTRA session is established, also using the IMS APN. This session has a QCI of 1 and QoS priority of 2. Unlike the other two sessions, this one does have a guaranteed bitrate. For Sprint, this bitrate is 39 Kbps. The screenshot below shows all 3 sessions: VoLTE E-UTRA sessions This is how VoLTE calls are prioritized over regular data. Normal data usage, such as loading a web page or watching a video, will still use the lower, default QoS (QCI of 9), while the data for the VoLTE call will be at the second highest priority (QCI 1), just after IMS signaling (QCI 5). The tower / eNB will ensure that the VoIP session always is able to use up to 39 Kbps by reserving that bandwidth and dedicating it to the call. This is in contrast to “Calling+”, which does not establish a separate E-UTRA session, and instead uses the normal QCI 9 session. The below screenshot shows an active Calling+ call. Note the presence of only a single E-UTRA session. Calling+ E-UTRA sessions So now that we have the airlink for VoLTE, what happens? VoLTE, Calling+, and VoWiFi are essentially standard SIP VoIP calls. The below screenshots show the SIP details for an active call, and the LTE Signaling messages that setup and then end the SIP call. VoLTE SIP details VoLTE Signaling For VoLTE, the traffic for the SIP call goes over the QCI 1 E-UTRA session instead of the normal QCI 9 session. This means that the eNB (tower) will reserve and guarantee 39 kbps for the call, but other traffic from the same device will not be prioritized and will use the normal session. So starting a VoLTE call will not make the rest of your traffic prioritized, it will apply only to the VoLTE call. So as a recap, when VoLTE is enabled, the UE / phone establishes multiple E-UTRA sessions. One is used for normal usage, one is used for texting and signaling, and one is used for the VoLTE call. Think of these like separate virtual ethernet cables. On the QoS prioritized and guaranteed bitrate VoLTE session, the UE establishes a SIP VoIP connection for a call. On Calling+ devices, the same SIP connection is used, however it runs over the default QCI 9 session instead, and therefore isn’t prioritized and doesn't have a guaranteed bandwidth. This is why Calling+ calls are more likely to cut out or not sound as good. VoLTE call Calling+ call VoWiFi (Wifi calling) operates almost the same way. Like VoLTE and Calling+, it also uses the same SIP connection for calls and presumably IMS for signaling, but instead of using an LTE E-UTRA session, the phone establishes an IKEv2 IPsec VPN connection to Sprint. This is an encrypted connection that allows data to be tunneled directly into Sprint’s network. The SIP and IMS traffic are then routed over this VPN to Sprint, but not other, normal traffic. From a QoS perspective, VoWiFi is identical to Calling+, in that neither are prioritized above other traffic. VoWiFi call Because VoLTE, Calling+, and VoWiFi all use the same SIP servers and connections, under normal conditions they sound the same and can technically hand off to one another. They can all take advantage of HD Voice codecs and should sound the same, since the call itself is identical across all three. The difference is how the data for that call makes it to Sprint. VoLTE is able to use a dedicated, guaranteed airlink to ensure that congestion on the network (LTE or WiFi) won’t adversely affect the call. One final performance benefit is that VoLTE is able to take advantage of something called RoHC (Robust Header Compression), seen in the above 3 screenshots. This compresses the IP, TCP, UDP, and RTP headers from 60 bytes to 1-3 bytes, resulting in up to 60% bandwidth savings. It’s only possible on a dedicated link, which is why VoLTE has it but Calling+ and VoWiFi do not. So not only does VoLTE have guaranteed, dedicated bandwidth, it will use potentially half as much, which matters a lot for maintaining the call in edge of cell scenarios.

    You guys are just falling for the propaganda. They all want us to think the Sprint's failure is imminent, if not even immediate, if the merger is not approved. You guys all mocked Sprint when they first were using hyperbole about their network and prospects when they played that card initially. And now going all ga-ga over the data again as if it was new info and now means even something more or different. This is all OLD NEWS. They want it rehashed and all of you to freak out and over talk about it, so general opinion is that Sprint is going to no longer exist with or without Tmo. But the reality is, as Brad mentioned above, Sprint is in better shape than it was last year, two years ago and five years ago. And also, I don't get the comment that "Softbank is looking for a bailout by any means necessary." Softbank is not looking for a bailout. No request of government giving money to save Sprint financially. That's a bailout. Softbank is looking for a BUYER. It's totally legit to look to sell the company. Why would this be surprising? Masa was discussing selling Sprint within weeks of buying it. That's always been on the table. And frankly, I wouldn't mind for someone to take over than Masa. A tie up with a cable company may be a very good thing for Sprint if the Tmo deal doesn't happen. But I fully expect a legal challenge if not approved. Robert

    Sprint has over 56 million customers, do we need to really go down this rabbit hole?! Is Sprint perfect? Nope, is any carrier perfect!? Nope. You should go with what works for you, if Sprint was somehow not meeting my needs, I would have moved on a long time ago. I'm not with them to save a buck, I'm still with them because the network meets my needs (and I consider myself a pretty heavy data user) and customer support has always taken care of any/all my issues. As a plus, I personally enjoy the community Robert and gang have created here, which has been extremely educational and enjoyable.

    SignalCheck 4.52 is rolling out to the masses! It should be available on Google Play within the hour. Here are the highlights: New options added: Added option to control display of horizontal signal meters on main screen. Added option to control logging of LTE sites if the TAC is missing/invalid. Added option to display LTE bandwidth on Android 9.0+ devices. This is nice, but not 100% reliable on most devices yet. Hopefully this improves over time. Added options to trigger Alerts based on specific LTE bands or plain-text strings. This is pretty cool.. you can choose LTE bands, and/or have the app alert on any text you want (or don't want, by using the "!" character). Set multiple alerts by separating strings with commas. Notable bug fixes: Resolved issue with app failing to exit immediately in certain scenarios. Resolved issue with missing data on Android Q Beta devices. Resolved issue with missing PLMN ID in certain scenarios. Resolved issue with missing provider database on Android 9.0 devices. Resolved issue with Alerts preferences not working properly on Android 8.0+ devices. Most of the Alert preferences are now handled directly by the system. Resolved issue with missing WCDMA data on newer devices. Some of these items were a lot more work than a brief sentence might hint.. many were significant bugs, some users will see great improvements! Other changes: Adjusted animated action bar tower icon colors when idle. Changed device location settings warning to reappear on every app update. Changed primary signal data source on Android 7.0+ devices. Disabled battery-related options for Location Service and Site Logger on Android 8.0+ devices; intend add back in a future update. Android no longer permits third-party apps to monitor power status changes; I am looking for an alternative method. Improved deployment process; releases will now be smaller, more optimized downloads. This is not a large app, but now it's approximately 30% smaller anyway. Thanks for all of your support! Feel free to shout if you have any questions.. -Mike

    Dave YeagerSprint 4G Rollout UpdatesFriday, February 8, 2019 - 8:00 AM PST Sprint’s tribanding project has reached a new phase -- former Clear LTE 2500 only sites are getting new equipment as reported by nowerlater in Cincinnati, Joski1624 in Cleveland, and here in Columbus. Converting sites from LTE 2500 only to triband LTE 800 MHz, LTE 1900 MHz, and LTE 2500 will significantly improve network performance in the traditional metropolitan areas of markets where Clear sites reside. Adding LTE 1900, LTE 800, CDMA 1x1900, and 1x800 will mean stronger signal with improved building penetration that will allow surrounding sites to better serve their more immediate coverage areas. This added site density will be a key factor in performance improvements needed for high quality VoLTE (Voice over LTE) service. Upon completion, site density for the non-LTE 2500 bands will increase an astonishing 57% in Franklin County (Columbus) Ohio. There are currently 162 macro sites not counting factory and private office building sites. There are 93 stand-alone Clear sites. Hamilton County (Cincinnati) will show a 61% increase in site density for the non-LTE 2500 bands. Additional Clear sites lie outside these counties in both markets. The level of increase will vary from market to market. Market wide LTE 1900 performance will improve if this increased site density allows for fewer 1x1900 CDMA carriers per site. This would allow refarming of spectrum to increase the bandwidth for LTE 1900. Minimum LTE bandwidth allowed by many of Sprint’s Remote Radio Units has been increased in recent months according to the FCC. This will be market dependent. There will be a 50% or more LTE 2500 capacity improvement at most Clear sites. Mini Macro Clear sites broadcast only one or two carriers, while most metropolitan areas triband sites broadcast three carriers with up to five carriers at some sites. The tribanded Clear sites go from having Mini Macros to 8T8R remote radio units at most sites, but some sites may retain existing Mini Macros in some markets. With 8T8R, these tribanded Clear sites will also get improved performance and coverage. Samsung Clear equipment used in portions of the south and east often have three carriers thus will primarily gain benefits from the improved coverage of the 8T8Rs. Tribanding the Clear Mini Macro sites will also improve the LTE 2500 performance of surrounding triband sites. If your phone is on the third carrier and you currently drive into an area primarily served by a Clear site your triband site signal will get weaker and weaker until it drops. The LTE 2500 at these existing Triband sites currently carries an extra burden. Permit Foreshadowing Let’s dive further into the details. We have been watching for these site builds for many months. Permits were first seen in the early fall in Columbus, for example: ALTC1800834: ANTENNA UPGRADE TO AN EXISTING CELL SITE OF SPRINT. REMOVE (3) ANTENNAS, (3) MM RRUS, AND (3) 15/64" COAX. INSTALL (3) ANTENNAS, (9) RRHS, (3) 1-1/16" HYBRID CABLES, GC SUPPLIED RET CABLES, (3) OPTIC FIBER JUNCTION CYLINDERS, (3) POWER JUNCTION CYLINDERS, (1) SITEPRO SNP-12NP SECTOR MOUNT AND HANDRAIL KIT. REMOVE EXISTING CLEARWIRE GROUND CABINETS AND INSTALL ALL NEW SPRINT ECAB & ICAB COMBINATION CABINET AND PPC ON NEW CONCRETE PAD. REMOVE ALL POWER AND FIBER CABLING TO RRHS. Permits and drawings were also found in Sacramento by our resident staff Tim (lilotimz), with one site even going from CA to Massive MIMO: The Network Vision plus LTE 2500 using 8T8R LTE 2500, LTE 1900, and Four Port LTE 800,and the much rarer Massive MIMO LTE 2500/5G future, LTE 1900 and Four PORT LTE 800. A big question was whether the sites would have CDMA or just be VoLTE. Most Sprint phones in use today can only use CDMA. OceanDave picked up the first Clear Triband Conversion signal in his logs recorded on 11/30/2018. Joski1624 found and confirmed CDMA 1x1900 and 8T8R LTE 2500 at the site once the logs were analyzed in early January. Here is a screenshot from Joski1624 showing LTE 800 and 1x800 from the same Clear conversion site: Cleveland has confirmed other sites. Nowerlater has reported similar results covering bands 25 and 26 from other Clear sites converted to Triband in the Cincinnati Market Here is a photo of a Columbus Clear site being converted to Triband. You can see that the Clear Band 41(inside red outline) is still wired and was quite functional at the time of the photo. 1) Clear antenna (remove), 2) Mini Macro (remove for most sites), 3) Microwave antenna for redundant backhaul (will likely remain if present). This is becoming a Triband Hexadeacport 16 port Antenna Setup outlined in yellow with 1) 8T8R LTE 2500 Remote Radio Unit, 2) LTE 1900 Remote Radio Unit, 3) LTE 800 four port Remote Radio Unit, 4) 16-Port Triband Antenna. In this next photo you can see the old cabinet on its metal grate and the new cabinet on new concrete. The underground conduit needs to be placed then the concrete poured before you will see cabinets. Some of the sites will have double cabinets (permits say Eltek, but observed cabinets do not match catalog). Note that they are pre-assembled, in this case by Stonecrop Technologies. These sites are also getting new Purcell cable boxes. In Columbus, 86% of the Clear sites have permits. New permits are still being filed. We began finding permits for Clear conversions last October. Permits are active for one year. They can be extended, but typically the work will be done in that time period. It is quite possible the FCC will not approve the merger into T-Mobile until December or later based on the Shentel – nTelos merger. This merger could finish sooner or not at all. If the merger is approved this work would likely stop, but any completed site work would benefit existing Sprint customers during the estimated two to three year transition period (market dependent). If all Clear sites were converted to triband, here is an image of roughly where the sites would strongly benefit in the traditional Columbus metro area: Please note that actual site coverage areas are not circular but are shaped between a three bladed airplane propeller and a three leaf clover. There would be significant variations from the heat map above. Of course Columbus overall has Network Vision and other Next Generation triband sites. These Ohio markets mentioned have active S4GRU signal hunters, thus are likely a proxy for what is happening or will happen in other markets with active former Clear LTE 2500 only sites (for clarity we will now refer to them as Clear sites). Indeed lilotimz has found permits and drawing in Sacramento. Reddit user Marley3456 has confirmed triband Clear sites in Salt Lake City Utah, thus they very likely exist in other parts of the country. The following cities in state order all had more than 10 Clear sites with LTE in 2014 thus are likely prospects for this type of change: If your city is listed above, how will you know if you will benefit? Start looking looking at the Clear sites in your city today and be observant of any changes. Help is available here at S4GRU.com if needed. Online guides can help: Nokia Mini Macros on Macro Sites, Samsung LTE 2500 Remote Radio Units and Antennas. It will be worth knowing if your market will benefit from the significant capacity improvements of the Clear site Triband conversions! Edited 2/8/19 to better cover Samsung Clear Sites.

    Yes, hindsight is always 20/20. None of these were completely bad moves in the time they were made, but just ended up in the wrong side of history in retrospect. If Sprint's decisions throughout time have always been wrong, then why are you even here in 2019? Get constructive or get going. Thanks. Robert

    No. A cable company buying out Sprint or T-mobile would be very likely better for the consumer as they'd have an incentive to compete and gain subscribers. It's only the natural path forward if one looks at how Comcast and TWC (Spectrum) is setting up things. They've already began building the infrastructure of supporting wireless users and triple play integration based on their MVNO setup. The next step would fully integrate those wireless users into their entire network top down instead of piggybacking off say Verizon. They can leverage their long haul fiber and last mile hybrid fiber coaxial networks to provide dedicated full speed backhaul to their own cell sites and new ones they can leverage using their own telephone poles and right of ways. It's one of the reasons why Shentel land is so amazing. Full vertical integration.

    Just a quick update for the Beta Crew, yes I am still hacking away at the new Alerts.. it is a lot of work trying to get everything working well on Oreo+ devices while not breaking pre-Oreo devices. I forgot how many ugly workarounds I needed to implement to keep everything working before. The new Android notification settings don't mesh well with my needs either, but it will get done. Just a tedious struggle. Side note, I accidentally stumbled across something I either didn't know or forgot about.. Pie introduced a new method to get the channel bandwidth, so hopefully that will be an easy and very cool addition making this wait worth it.. stay tuned.. -Mike

    I'm no moderator here officially, but I've served as one on many other sites, both private and commercial/for profit, and just want to underscore for you guys continuing this: both Robert and other mods have warned you, and yet you're continuing the political-based discussion. Just to interject a friendly alternative suggestion before one of them comes in here and acts on that timeout threat - you could just as easily continue these back-and-forth arguments directly via private messaging, which the site supports. It's your choice whether or not to do that, but you can continue as you are, or have that choice forced on you the hard way.

    This is a non-sequitur. My whole point was that they have the service on paper, but not in reality. If they put 5G-NR on 600 MHz on those same towers that currently have 700 MHz, they can fill a map full of rural areas running "5G" with the actual service being as poor as it is today. (And, if 5G-NR is a more fragile airlink than LTE, then it will be poorer.) Spectrum is not the issue, deployment is. Lose how? Once they've merged, what is the remedy if they decide to give the FCC, DOJ, and the American people the middle finger? I remind you to check out all the remedies that have been used on AT&T so far, such as... ... huh, I can't think of any. - Trip

    Look like another M-MIMO antenna added at East 14th Street and 2nd Avenue, above the IHOP Restaurant building. The mini macro is still there and it is live pulling 167 down and 14 up at 12:30 PM. Sprint replacing 8T8R and mini mac for M-MIMO build so fast in Manhattan, some of them leave 8T8R and mini macro antenna up there.

    They really need to get this guy out front more. He is obviously knowledgeable then proceeds to explain this upgrade to a group in such a concise manner, even journalists can understand it well. John is funny and charismatic with the crowd, he has been with Sprint for so long. Marcelo went from surprise new CEO, awkward Wall Street talking head appearances, to selling a merger. No one is really sure what his customer facing role is outside of rich people poasting on Twitter. Another great presser from Dr. John. Thanks for finding this NextgenCPU!

    Going off topic a bit, the merger that I wished would've happened a long time ago is MetroPCS and U.S. Cellular. Their networks would've complimented each other so well and they would've been a decent 5th nationwide carrier with a combined 14 Million customers.

    Screen protector is great, well done Samsung. I do have to say, this phone is a beast for rf performance, I'm at work in the basement and I haven't dropped to 3G yet, still holding onto 2-3 bars of LTE. VoLTE worked fantastic just a few minutes ago very clear.

    First, I want to state on the front end that if you read this and feel uncomfortable by it, I understand - I've been on the other side of these things myself when I've seen them posted say on Facebook particularly, though I've tended to be more willing to help out here when I've seen them. I even feel uncomfortable posting it to some extent, but I'm just simply trying to help out family in any way I'm able. I also want to state that I requested and received Robert's ok to post before just doing this arbitrarily. Let it be understood that even that being the case, S4GRU is not in any way directly tied to this. This is just a fellow member asking for help from anyone willing on behalf of family, and again, I just want to stress that if you feel uncomfortable with helping out here, no worries - I totally understand that perspective will exist and apologize up front, because no offense is intended, and none taken by me for anyone that feels this way and moves on to the next post. With that out of the way: My wife's niece and her parents are in a real bind right now, and had to resort to the GoFundMe route to try and cover necessary medical expenses for past treatment attempts as well as the last resort treatment for her finally landed on diagnosis of Autoimmune Encephalitis/PANDAS. For the 'last resort' angle, basically there's a drug treatment that was primarily developed for cancer patients but has around an 80% success rate treating this particular disease. The initial blood work for her, from what they were told, looks positive in her case that this should be treatable with this method. The only problem is, the treatments cost $16k a pop, they require the money upfront before they'll administer the treatments, and insurance won't cover a penny of it, at least for someone based in Pennsylvania. Right now they've raised enough for one treatment, and gotten past it, but they're not where they need to be yet past that for the 2nd one last I've heard. I think is technically supposed to happen 2 weeks after the first timing-wise The link to their GoFundMe follows: https://www.gofundme.com/morghan039s-medical-mission First and foremost and above any financial assistance, for anyone of faith and willing to be receptive to that angle (and I understand going in, not everyone will be), and her parents would tell anyone this to their face - they ask for prayer. True, genuine, heartfelt prayer, because they need a great deal of it - that not only can they finish out this path, but that it actually works, because so far as they're aware, this is their final shot for a resolution. Past that, if you're willing to donate, that would be greatly appreciated. If this is something you're sympathetic and you're also not uncomfortable sharing on Facebook with others you know, that would be appreciated as well (there is a button link on the page to do this). Particularly on the latter however I especially understand if that's beyond the personal comfort level. And my humble and sincere thanks in advance for anyone just simply taking the time to read. No responses in the thread are really necessary for my part - again, just trying to help beyond how we already have otherwise by trying to spread to word to anyone willing to help. Tim

    Promise in one hand and do something else in the other... Fact of the matter is that right now, while T-Mobile has made the map look good, the actual service in rural areas is not good--at least in my experience--and that's with LTE. I'm not confident that the merger will improve this. I'm not sure why you expect it to. Are they going to put many billions of dollars into an escrow account that will be used only to fund rural deployment within a certain time frame and be forfeited to the government if not used? If not, then what is their promise other than words that could easily be ignored the moment after the merger is approved? Remember the time AT&T promised they wouldn't increase prices after merging with Time Warner and did so twice within a year? What was their promise worth? What makes T-Mobile's different? - Trip

    I believe it. They can certainly operate 5G-NR on 600 MHz, which I assume is what they plan to do. If, as some articles have suggested, failure to operate 5G-NR in mmWave spectrum makes it not "real 5G", however... - Trip

    Want to correct some inaccuracies in this discussion: 1. Nextel did not have a lot of 2.5 GHz spectrum. Just 30MHz of BRS. Sprint through their failed Wireless TV venture that later became their failed fixed wireless venture owned the other 30MHz. But that BRS they got from Nextel came with a deployment mandate and that what brought forth Wimax. They could have chosen to implement UMTS on it but they did not. Clearwire leased the vast trove of EBS from educational institutions and the Catholic Church. 2. Sprint was a partner along with Cable companies in the first AWS auction. But they did not have money to deploy it and the cable cos sold it to Verizon for $4.4 B and the promise for cheap MVNO rates. Xfinity Mobile and Spectrum Mobile are their children of that sale.

    5G can be a real differentiator for Sprint. Hopefully it’s a rapid and wide deployment.

    Ookla found that T-Mobile's network was the fastest, followed by Sprint, then Verizon, and finally AT&T. https://www.speedtest.net/insights/blog/football-stadium-speeds-big-game-2019/
