  2. I went to the Sprint Call Center today in the Albuquerque suburb of Rio Rancho. I thought I may be able to sniff out some LTE there like the one near Denver. Sadly, I did not encounter any LTE. I even went inside. But I did discover eHRPD. At first, I thought the eHRPD was just at the Call Center. But it appears to be throughout the ABQ metro area. I drove all over Rio Rancho and the ABQ west side changing sites more than 10 times, and I'm still on eHRPD. Looks like we are eHRPD live now. I took several screen shots. Performance is identical to EVDO-A when connected to the same sites. As expected, the site where I get 2Mbps+ site speeds (at Unser and Paradise on the west side) is still just as fast on eHRPD. But I always get those speeds there. Robert on Samsung Galaxy S-III via Tapatalk

  4. We have started a new thread for KAW-DAW. The previous thread is over 7,000 entries and has been closed. It ran for three years! If you've never played Keep a Word, Drop a Word before, it is really simple. See below... Example Post 1: customer satisfaction Example Post 2: tough customer Example Post 3: tough break Example Post 4: break wind Comprendo? See, it is really simple. For each new post just keep a word from the previous post and drop the other and replace with a new one. Please KEEP your posts to JUST 2 WORDS, but if you are stuck and must to, you can include a "helper" word, like: a, the, an, etc. BUT the next post CANNOT use that "helper" word as the one they keep for the next post. You can however use the same "keep" word as the previous poster if you want to. Otherwise just have fun with it and let's see where it goes? If things get stalled out just start a new line of thought by making a new 2 word saying. I will kick off the game below...
  5. Activity is well under way in the VT/NH/ME market from vendor Alcatel/Lucent. GMO sites are nearly 100% complete, and full build sites recently began. I am creating this thread as a placeholder for our members to discuss Sprint Network Vision deployment in the VT/NH/ME market.
  6. by Robert Herron Sprint 4G Rollout Updates Wednesday, July 16, 2014 - 5:30 PM MDT Hold the phones! One day, you won’t have to worry about holding the phones as Sprint moves to VoLTE for its voice telephone services. That is because VoLTE (Voice over LTE) will allow customers to do a voice call and LTE data simultaneously. S4GRU is now able to confirm that Sprint is proceeding with Voice over LTE based on detailed information from an anonymous Sprint executive. He was able to confirm some of their plans for the transition to VoLTE for voice. In recent months, Sprint has been quite mum about moving to voice over its LTE network. Maybe even a bit misleading about it. Causing some to believe they may not even move to VoLTE at all. Public quotes from Sprint have reiterated that CDMA will carry its voice needs for the foreseeable future and not being in any rush about going to VoLTE like all their competitors have proclaimed. And based on this new information S4GRU recently obtained, it will certainly not be rushed. But Sprint is moving forward with a solid VoLTE plan that will see the lion share of its voice usage move to LTE. This is a relief to some S4GRU members, as they have been getting anxious as they hear other providers publicly extol their upcoming VoLTE networks. We will discuss some details of the plan as they were shared with us. The Sprint VoLTE plan Currently, Sprint is in the programming phase of VoLTE. This includes all the design criteria and functionality that can and should be included in their VoLTE system. This includes discussion and feedback from device and network OEM’s about feasibility and hardware support. When this programming phase completes this summer, it will then proceed with an FIT (Field Implementation Testing) phase. During the FIT, they will be able to discover any issues and bugs that need to be worked out before OEM’s start mass producing equipment and VoLTE is instituted nationwide on the Sprint LTE network. Sprint VoLTE FIT’s are planned to be in Kansas, Greater Chicago (Illinois) and Virginia. Key roaming partners will participate to ensure interoperability. An opening up of the VoLTE network to customers will be in a future implementation phase that is yet to be scheduled. The schematic schedule would have that be in Mid 2015, but it could be sooner if everything goes well in the wrap up of Phase 1, the FIT and the availability in the device ecosystem is realized. Key Points Sprint is proceeding with incorporating VoLTE into its network to capitalize on the following advantages: To support both domestic and global roaming for its customers and customers of other VoLTE providers Reducing the CDMA network (capacity, not coverage) by removing most of the voice burden to allow for spectrum refarming for additional LTE carriers (capacity) VoLTE will allow HD Voice to be interoperable with several other providers by using the 3GPP EVS (Enhanced Voice Service) codec and integrating other networks together Additionally, here are some details about how Sprint will implement VoLTE: The Sprint VoLTE network will be designed to hand off calls to the existing Sprint CDMA network, including HD Voice calls, via the EVRC-NW codec EVS codec standardization may not be achieved by the time Sprint starts deploying a VoLTE network. They will use AMR-WB and EVRC-NW for testing initially. This may limit initial interoperability of HD Voice in the beginning. Sprint to SoftBank Mobile VoLTE calls should be able to use HD Voice from the beginning, and vice versa. Sprint will leave some CDMA voice capacity indefinitely. However, ultimately the goal is to remove CDMA 1X Voice when coverage and quality is equal or better than customers experience today. Additional low frequency spectrum may be required, depending on future voice demand which is steadily declining. VoLTE calls will not be given QoS Priority on LTE initially. Should LTE capacity constraints be experienced during a VoLTE call, the call will be handed over to the 1x network. As the LTE network matures and loads are better balanced, voice on LTE will be given priority over other LTE traffic similar to WCDMA networks. FDD LTE networks will be preferred for VoLTE traffic over TDD LTE. TDD already has the uplink slotted for maximum data download efficiency. Adding additional uplink data demand for voice (which is synchronous in nature) on TDD (which is not synchronous) may cause a noticeable data upload degradation in voice demand scenarios. Due to FDD being synchronous in nature like voice calls operate, Sprint VoLTE will prefer FDD LTE over TDD LTE when possible to provide for the best network operation. Interoperability over getting it installed now One of the key reasons why Sprint is going to be last to the VoLTE race is because of interoperability. The most important attribute to Sprint for VoLTE is roaming with other providers. Early VoLTE networks will either not support interoperability, or will require significant upgrades or network changes to allow it. VoLTE is only now maturing to a state of interoperability where there are enough standards to ensure a system that can work with other providers. Unlike the Duopoly and some other early VoLTE adopters who may not care for an open voice network, and may even be against it, Sprint is making sure that its network is designed with interoperability in mind. So it works with other providers from the beginning. Sprint is likely working with CCA and RRPP members. And this makes sense in context with remarks recently from RRPP partner VTel in Vermont. The Sprint network is being designed from the get go to make sure it can host roaming for other LTE providers around the country and around the world, and also that Sprint VoLTE devices are capable of roaming on partner LTE networks as well. LTE can finally be that bridge to a cohesive global voice and data network among different providers. Since the world is embracing LTE as the de facto standard, it would be a shame to miss out on that level of interoperability. Granted, there will be some band support issues, but OEM’s have made great strides in providing devices to handle a great many bands these days. The current Nexus 5 model supports many LTE bands already. Sprint is banking on the slower and well planned route to VoLTE is going to provide a better network to seamless global interoperability for Sprint customers. Now if the FCC and DOJ will take notice and stop the Duopoly from buying out CCA members. This is the largest threat to competition in the wireless market currently, in my opinion. CCA Member Coverage Map. This is an illustration of what LTE and VoLTE could look like upon all existing CCA members upgrading to fully interoperable LTE/VoLTE networks.

  12. Exciting update! Thanks for the info. Keep us posted. If Sprint doesn't work out, you can get a Google Fi account, and then force it on to Sprint network with a dialer code. Robert

    Good question. I don't know. But I believe Sprint has a PCS spectrum agreement with one of the Alaska carriers. Robert

    The Sprint sites coming online around Anchorage, Alaska are going live 3G and B41 only. But these are former Clearwire Expedience sites. I haven't seen any so far that are not former Clearwire sites. Robert

  17. Yes, you're correct. However, the Erie to Rochester swath only has 3MHz available for deployment. Only 3 MHz. So it can only be CDMA or LTE. As the total width available is 3x3. Not enough for LTE and CDMA together. And there is still an outstanding exception for the Buffalo/Niagara region. That still requires further coordination with ISED Canada. Robert

  19. Calling Plus and WiFi calling solutions are a type of VoIP. VoLTE is also a type of VoIP, specifically designed for LTE networks. Calling Plus is not VoLTE. But both are VoIP's. Your analogy is like saying an Audi and a Cadillac are the same because they use the same highway. Just because both can run voice across an LTE network does not make them both VoLTE. But there are many similarities. Just like to a caveman, the Audi and Cadillac would be nearly identical. Robert

    True. And the opposite is also amazing. People who say, "I have a problem, therefore it is ubiquitous." Robert

  23. It's supposed to. If B25 and B26 are both available to the handset, it should be using B25. It should only be running on B26 for a voice call when B25 is unavailable or cannot handle the throughput/latency for call quality. Expect the same for VoLTE. Robert
