    And what will this all mean for S4GRU? We are in a wait and see mode before we decide how to adapt. Until then, we will be here every day with you all, plotting our wireless destiny. Robert

    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.

    Alright. There may not be a Sprint anymore, but the same rules apply. Just incessant complaining about the old Sprint is getting old. People will start checking out because it just will become a complaint board. Constructive criticism only, please. Robert

    And this is the truth that many of us are going to learn. T-Mobile is not perfect everywhere. They have some markets where they have some real bad towers here and there. And there are some entire markets that aren't that good. But if the New T-Mobile fully leverages Sprint spectrum and add every Sprint site that expands coverage or provides additional capacity, it will get really good. Probably the best. Sprint failed to leverage Nextel sites to expand coverage and capacity to its full extent. Not even half its extent. Hopefully NTmo will take it to the maximum. But their comments about existing Sprint sites sound kinda lukewarm. No I won't hold my breath. If Tmo really wants to take it to the Duopoly, they need to keep every Sprint site that adds any coverage (and upgrade it, of course). They should also try to add Nextel locations that expand coverage too. And then any Sprint in-footprint sites that are not co-located With Tmo where density improvement or capacity would be helpful.

    I knew this day was coming, and yet it's still a bit heartbreaking now that it's finally here. Sprint had some ups and downs. The most positive thing I can remember against the other three was the old Google voice integration. Largest negative would be the VoLTE rollout. It was a blast going through Wimax, the LTE launch, triband LTE, and then finally 5G NR. Getting to have tower maps through S4GRU was a huge part of the experience. It definitely wouldn't have been the same without this place. A big thanks to everyone at S4GRU over the years, and I hope the transition goes as well as it can for all the current Sprint employees.

    I'm definitely going to miss Sprint. It's like a homely introverted ex-girlfriend. She's a cheap date and just likes to stay home (on WiFi). You know there was so much potential, if she could just be what you wanted her to be. Get moving, get out of the house, get a makeover. You weren't in love with her, and made so many excuses for her to all your friends. You've been meaning to break up with her, but you didn't want to end up with one of those 3 other narcissistic chicks out there, who really didn't look much better with their makeup off. Eventually she just finds someone else (T-Mobile). Robert

    It's also interesting to see through the lens of history that Dan Hesse is seen as a great CEO at Sprint. Dan was the right guy for the right season. It's the Masa season that will likely be judged harshly. And now we are in a new season. All hail the new supreme leader, Mike Sievert. Robert

    Sprint's situation is not dire. They still have over 50 million postpaid customers. There is a relatively high churn rate, but people are not fleeing for the exits. Most of that were temporary customers they tried to entice away with promos. In virtually every metric, Sprint is in better shape now. Financially and network performance. And frankly, their current and future capex plans are more realistic and better serving. They are much more in line with what Tmo did to get itself out of its rut back in 2012-2014. Focus on urban markets first, then suburban and secondary markets. And if you play your cards right and growth starts to occur after a few years of doing that, then they can make an exurban/rural move with major highway expansions. But Sprint cannot put the cart before the horse again this time. This is a much smarter plan. We all want Sprint to be the hard charging Number Four carrier that quickly surpasses the others to become #1 or #2. But also, there are ways to be a successful company and stay #4 forever. If Sprint cannot merge, it is still completely viable to run on its own. But it will be a long process to gain more customers or move up the rung. And I think most of us believe the network experience will be the best way to do that. And Sprint needs to start with the highest concentrations of customers first, to get the most bang for its buck. But Sprint is highlighting the darkness in their current status, because it is trying to get a merger approved. And that's going to give a lot of fodder to the unbelievers. Shun the unbelievers!

    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

    Agreed. Verizon is over rated and doesn't serve the hype. Sprint is under rated and doesn't deserve all the trash talk. People pick winners and losers and over claim the positives and negatives of each. They have to have someone to cheer and someone to jeer. If you aren't first, you're nobody. I have a Verizon work phone. It rarely wins in total speed throughput compared to my Sprint and T-Mobile phones (and USCC on Google Fi). Verizon doesn't win in coverage in my area. But it's a pretty consistent experience. And that's good for a lot of people. Let them have Verizon. But Sprint has pulled off nearly a miracle the past few years with little capital infusion, in a highly competitive environment and spending billions still in capex. They just have had to be very deliberate and measured where and how they spent it. Every year since 2011 Sprint was nearly going bankrupt in the eyes of the naysayers. Every year, they would claim this was the year they were going to lose it all. Yet they still have over 54 million customers. They are nowhere near bankrupt, and doing better by most measures. And soon it won't even matter. Because Mr. Legere will be in charge of it all. And Sprint will be a forgotten name. But they were not bought out of bankruptcy sale and were not even close to bankruptcy. Robert

    All it took was money. Network Vision was planned properly initially, but not properly implemented due to finances. I remember hearing early into the Network Vision deployment the CFO says publicly something to the effect of, 'The beauty of the Network Vision deployment plan is that we can ramp up or slow down as necessary depending on finances or need.' It was scary to hear then, and even scarier to think of in retrospect. They were confessing that they were always concerned about how to financially pull it off that the had contingency plans of how to "half-ass" it if necessary. And they did half-ass it, and it likely was necessary. But they did. And then once you get used to losing, you forget how to win. We finally got to the point that no amount of money would fix the problem anyway. Network wise, Tmo merging with Sprint will likely be a very superior position than both going alone. The big tell in time, is what it will do to competition and pricing for the long term. That's the part we don't know. Will it be worth it 5 years from now? Who knows? But at least we will enjoy the network improvements in the interim. But even that is not totally all everyone dreamed it would be in the short term. I guess nothing is perfect, but we always imagine it will be. Robert

    Holy crap, go Nokia: Nokia touted a new lab achievement over Sprint’s 2.5 GHz spectrum that boosted 5G capacity by up to four times through a software upgrade. The test included a software upgrade of E-UTRAN New Radio – Dual Connectivity (EN-DC) and Multi-User-MIMO (MU-MIMO) using Sprint’s mid-band 5G spectrum and Nokia’s AirScale solution to deliver 3 Gbps total downlink cell throughput, in what Nokia called a first. It showcased Nokia’s AirScale Dual Mode Massive MIMO for 5G and LTE, using a single radio unit for both LTE and 5G. The test also tapped commercial hotspot devices. Nokia said once its service is commercially available operators will be able to “vastly increase” network capacity through software updates to the base station, without the need to invest in more spectrum or require site visits to swap out hardware or transport. https://www.fiercewireless.com/5g/nokia-notches-5g-capacity-boost-via-software-upgrade

    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.

    The New Tmo has lots of BRS in rural areas. Tons. Just not nationwide. And they have EBS licenses in most of those rural communities if they have a university or other educational system where they have a lease. Think Rapid City and Pierre, South Dakota as examples. As well as Albuquerque and Las Cruces, NM. Although there may be more rural areas they would like to pursue more B41/n41 spectrum through leases or acquisitions, they are still in a very good position. Frankly, if a lowly rural interstate towers only has BRS and no EBS, it's going to be way more than it needs to serve the customers that drive by it. And expect Tmo to add B41/n41 to these areas last anyway. Robert This is a Spectrum Omega map edited to show BRS T-Mobile holdings. It includes every BTA that T-Mobile has any BRS spectrum. The ones in gray show BTA's where someone else owns the BRS license. And no color means no one is shown as a licensed BRS holder for that BTA.

    I became a Sprint customer on June 4, 2010 with the launch of the HTC EVO 4G. I came over from AT&T. I had just moved to New Mexico earlier that year and had virtually no AT&T Service in my area. Sprint had decent coverage, and I thought I better move to a "4G" device if I was changing providers and getting all new equipment. The rest was history. You know, we are coming up on the 10 Year Anniversary of the HTC EVO 4G launch. 10 YEARS!!! It really is what was the catalyst that caused S4GRU to come about. If I had gone to Verizon, this site and all the past 10 years of 4G hunting never would have happened. It was really a close decision. I think the cost of adding a line for my then 13 year old son is what probably pushed me over the edge. What's funny is I pay about the same now for 5 lines on T-Mobile what I paid for 3 lines on Sprint back in 2010. Robert

    I'm not convinced much has actually changed yet. It seems to me like they've opened up roaming a touch more, but otherwise Sprint customers are still on the Sprint network as much as possible. I have yet to connect to T-Mobile anything since the day of the merger. - Trip

    It’s crazy because years ago when Sprint had all this 2.5 spectrum. All the other carriers talk so bad about it and how it can’t penetrate a paper bag. Now it’s considered the spectrum of the future and now it’s Mid band and not high band.

    Was on one of the tech channels on YouTube... A Sprint tower tech was saying speaking in anonymity that on closing (April 1) they are setting up to open the networks. Meaning, via software update, Sprint will have access to T-Mobile and vis-a-versa... on April 1st. Hoping this is true! On Tower Integration... They are setting up Integration do begin nearly immediately as they are set to do market by market tower integrations (combining towers/ moving equipment to best site). They will be doing massive mimo upgrades as much as possible at the same-time on 2.5, band 41, Band 25 (1900 sprint) band 2 (1900 T-Mo.) and Band 4 (TMO 1700/2100) According to him, they have the maps ready and will only be combing towers that are very nearby each other to avoid interference. The network integration will take approx 2 years, but realistically less. Again, this is market by market... (Metro area- by Metro area). Thoughts? ...

    All: I've been busy the past two days converting maps to BatchGeo. Which will we use to host our maps temporarily for a month or two while we work out a better long term solution. If you want me to recreate a map in one of your threads, send me the CSV file of the data and the the thread URL and I will create it in BatchGeo. I'd like to try to keep the site not looking like we were napalmed and burned up all the maps. I'm happy to create the maps for you. No matter how old the data. I like having historical data from years past, especially instead of broken links and missing maps. BatchGeo is limited to just 25,000 markers. So maps with more than than will need to be broken down into multiple maps. There is no extra charge for additional maps. We just pay a flat $99 per month fee. THANK YOU EVERYONE who have been helping with the maps. It is greatly appreciated. Robert

    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.

    I wish I had the screenshot, but it's sitting on my US Cellular phone at home. I forgot to post that on Friday, my wife and I went out shopping and I noticed my US Cellular phone was roaming on T-Mobile LTE instead of Sprint. I was trying to get it to look at Sprint B25, so I locked it to Band 25 to try to force it onto Sprint. I then found myself connected to T-Mobile B25, which was on the T-Mobile PCS carrier. They must be running MFBI on it now. I'll post my screenshot of it in SCP after work. - Trip

    Yes. But we didn't live in a bubble. There were two other vendors. Ericsson was clearly the worst of the three in Network Vision deployment (in some ways they had to do it twice). Also, when it comes to network management, a third party will almost NEVER do as good of a job yourself, because they don't take ownership of the issues the way you would yourself. And so there is not the sense of urgency when an issue or roadblock comes up. And you're much more likely to accept no as an answer. I see it all day long in my line of work. Robert

    Sorry for being late to this and some of this is repeating New York. They have $7 billion in cash and just under $10 billion in liquid assets. I guess I read that differently than you do. From the investor update presentation they've basically got enough liquidity to pay off their debt for the next two years if they do nothing at all. What will happen is what has happened for years. You'll likely see Sprint offer new notes at some point this year that will replace the debt or expand it further. He isn't talking about a "massive restructuring of their debt" at all. He is talking about what Sprint has done in the past and will continue to do going forward. Sprint has roughly $4.3 billion in debt due this fiscal year. If they issue $4.3 billion in new debt ceteris paribus their debt and liquidity positions haven't changed. They aren't refinancing $40 billion in debt. As maturing debt is retired they are issuing new debt. The next 3 years that is $4 to $5 billion a year at a time. Presumably indefinitely as long as someone is willing to lend to them (which there is a finite point somewhere there), but especially in the current economic conditions Sprint didn't have any trouble getting money last year and actually up-sized an offering due to favorable interest. The Free Cash Flow thing is a little weird. As a customer, I'd prefer Sprint invests in their network, something they did up about 50% year-over-year. That spending is going to drive Free Cash Flow down. If they had spent about $1 billion less in Capex they would've been free cash flow positive, which again is meaningless to me as a customer. It also isn't a really compelling failing firm argument, which is part of the reason they're having trouble convincing the DOJ of their arguement here. T-Mobile hasn't been FCF positive* since 2015. *using Cash from operations less capital expenditures

    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

    You both need to stop it and stop it now. Any further arguments between the both of you will result in a time off on the forum. TS out

    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

    It's been many years... but we're going to finally see the true power of 2.5GHz. Proper backhaul does wonders.

    It's not as if Sprint engineers themselves didn't want to get things done. Top down decisions were made which basically precluded sprint employees from doing anything useful to improve the situation of the network. It was a multi year process but Son got what he wanted in the end after the "merger" was rejected the first time around. Not that it matters anymore. It's one for the history books. We'll just have to wait and see what New TM does with all the former Sprint assets they acquired. Sent from my Pixel 3 using Tapatalk

    Why did that last part actually make me a bit sad? Like saying goodbye to an old friend who was always there but maybe you'd simply outgrown. Lol

    We know that T-mobile does have more sites than Sprint, but this quote just implies it has at least an equal amount of sites as Sprint +1.

    Tonight I received several text messages while in the basement at my work (Boston suburbs), somewhere I have never even gotten a glimpse of Sprint service, or roaming, or anything.. checked SCP, it was moderately strong T-Mobile B66. Something definitely changed, because I've never caught that before. Sent from my Pixel 4 using Tapatalk

    Can't say who said, but looks like some of the network hiccups on the T-Mobile side are due to software and migration going on. Also found out T-Mobile is sticking to the original plan (2 years ago plan when merger was announce) to use the T-Mobile network as the "Host" network, move the sprint customer base over to it quickly as possible and then use the Sprint equipment from the old Sprint network to add on and enable additional load (Market-by-Market) until complete. Currently T-Mo is increasing use of it's AWS spectrum and Dish's to be able to handle the addition of Sprint person's on to it's original network. It's going on now. Philly is first. Don't know details as to who-else is being upgraded at this time. Anybody else having odd network things going on? Might be an indicator your market is undergoing transistion.

    Here we go!!! T-Mobile and Sprint are finally merging: What you need to know about the $26.5 billion deal

    Yes, some of you disagree with me. That's to be expected. Sprint sucks in some places. But Sprint is not only great in my area, but they're actually the best. And in most metro areas, they are perfectly usable. But guess what? T-mobile sucks in many places. And I can tell you here in their home market, they're the worst carrier. Verizon also stinks in places too. I suppose if I lived in a crappy Sprint market, I'd go. But I can tell you I see more and more people who leave Sprint and either come back or even if they don't, admit that the network wasn't as bad as they thought and there was a complete over dramatization in the disparity in networks. Everybody's gotta do what's best for themselves. And if leaving Sprint is best for you, I certainly wouldn't hold it against anyone. I've seen many go over the years. And I still sit here plugging away behind the keyboard. But the one thing that won't continue is the overly negative drumbeat that's happening in this thread. You all are starting to build off each other's negativity, causing the conversation to become one sided and pointless. Don't want to hear ad infinitum the same droll negative grumblings. Especially the same 'ol criticisms and Sprint can't be trusted. Frankly, the drama is not true. Sprint took longer, yes, but it did upgrade its network, and the performance is better. And on the whole, it's better than its ever been. So it cannot be said Sprint didn't do it. They did. So let's stick to the thread discussion, which is the merger. Not on the network performance on Lower Botswana Avenue and your thoughts on changing networks because of your block. Robert

    Posted an update to the Top Donors list. Justen moves way up the list to #4. Brockeb1 has made it on to the list and jumps all the way in to #28! jlbattagli, Trip, and runagun also moved up quite a few spaces. Rawvega made it back on the list. And thank you for all your time on the list, but, lrosete777 and leerage were bumped off the bottom. THANK YOU ALL FOR YOUR SUPPORT!!! Robert

    Please demonstrate what consequences AT&T is facing for raising prices twice in the year after their merger, despite representing to regulators that permitting the merger with Time Warner would permit them to lower prices. - Trip
