  1. That is the biggest problem with TDD config 2. Sacrificing upload speed for more download speed may be fine for the average user somewhere else but there are large events and special locations where lots of people take lots of pictures or videos and upload them. In those cases, the normal TDD config 2 (12 to 1 download to upload ratio on a single carrier) of band 41 does not work well and gets much worse with 2 or 3 carrier download CA with no upload CA. Since we do not yet have FDD + TDD CA or TDD upload CA on most devices, I would like to see Sprint develop better band steering algorithms that temporarily move heavy uploaders off band 41 to the available band and carrier with the most upload capacity while they are uploading.
  2. How long do people keep their phone before upgrading? The chart in that article indicates that as of end of 2016 in the US, half of the population upgraded their phone before they were 22.7 months old and half after that. I do not have the statistics but I would guess that somewhere around 10% still have their phones 36 months (3 years) after they purchased them since 30 month financing is now common. These numbers are likely higher for tablets, IOT devices, and other non-phone mobile devices as those devices are typically upgraded less frequently. What this means is that 1900mhz CDMA voice channels likely cannot be fully removed until Sprint has not sold or allowed to be activated 1900mhz only CDMA devices for 3 more more years to avoid impacting a lot of users.

  4. On most sites that you have to log into for every page you navigate to in a browser, the server double checks that you are still logged in before sending the information back to you. This is done by sending in-memory or on-disk cookie information back to the server you are requesting the page from on every page request. This information is normally encrypted for banks and other sensitive sites but a bad WiFi hotspot can quietly switch you to pages that are not encrypted while sending and receiving pages that are encrypted from the site you are using. The bad WiFi can then capture that cookie information. This is far less useful than capturing your account and password but if you do not log off, that cookie information will be good for a short period of time before the server considers it timed out. The best ways of dealing with this problem are to not use open WiFi connections, to use a VPN connection to ensure your communications are always end to end encrypted, or to always verify that the padlock is in place on every sensitive page you go to. You should always enable 2-factor authentication to any sensitive site that offers it as well. This will stop people from getting into your email and then using that to get into your bank or other sites by clicking the I forgot my password link and getting the reset your password email that it sends.
  5. The following scenario does not happen often but it does happen. Any open WiFi hotspot can be easily spoofed by a bad person. The bad person runs their own WiFi hotspot with the same name as the one you are trying to connect to but with a stronger signal and you cannot see any difference between the good WiFi and the bad WiFi. If you connect to the bad WiFi rather than the good WiFi, all your traffic will be routed through the bad person's device and then to the good Wifi so it will appear to work normally. The bad WiFi has the ability to modify your internet traffic whenever your device asks for encrypted pages and any page with an account and password to strip the encryption off the pages so that they can capture your accounts and passwords. At some future time, all the gathered pages, accounts, and passwords are sold on the dark web and someone takes over your email, banking and other accounts to send out spam or to take your money.
  6. Verizon built the DAS and Sprint is using it so I assume it is available for all the carriers. In addition to the 800 DAS antennas, there are 1300 WiFi access points in US Bank Stadium in Minneapolis.
  7. 800 DAS antennas for around 72,000 users is 90 users on average per DAS antenna with most of them not Sprint customers. You will probably see an average of less than 20 Sprint users per DAS antenna. 224mbps down and 8.8mbps up (2xCA Band 41) should be perfectly fine for well more than 20 users to share although it could be a little slow uploading pictures and video clips.
  8. The general rule for mobile coverage is that coverage needs to match up to the road network. If you want to know where the population lives and works, More than 95% of the population are always within about 10 miles of anywhere where there are roads with 2 or more lanes in each direction or are driving on those roads with 2 or more lanes in each direction passing through that area. Once you get about 10 miles outside of the multi-lane road area to single lane in each direction roads, you are in rural areas with very few customers. In my opinion, native or native-like roaming coverage covering the multi-lane road areas makes the most financial sense for Sprint with slower limited roaming outside of those areas.

    Official Airave 3 LTE / S1000 NSC Thread

    If it has problems, most routers and cable modems that use NAT tables have the ability to put a device in the DMZ so that they do not go through the NAT layer on that device.
  10. What I mean is that I can get 100Mbps download speed but I am limited to a 1TB cap. That is an unreasonable cap in my opinion for the speed offered. If you actually use the connection speed that you are paying for, you will quickly find yourself at the cap. A 1TB or 1000GB monthly cap equates to around 33GB downloaded or uploaded per day. At 100Mbps, you can reach 33GB of data downloaded in just over 45 minutes or 1/32 of a day. Because of my job I usually go past 33GB uploaded/downloaded every day that I work from home. I normally exceed 1TB of data usage well before the end of the month. If however I was only using content that my wired ISP wants me to use, that data usage would not be subject to the 1TB cap and I would not have to pay extra each month to use it.
  11. Sprint needs to spend 2018 chasing down areas where there is no ability to use data while on a Sprint device. This can be due to no service areas or saturated data connections on Sprint's or their roaming partner's networks. The "can you hear me now" guy should change into the "can you use data everywhere you go" guy. I am not concerned if the coverage is Sprint's or extended LTE roaming as long as it has a reasonable speed to use VoLTE and use the apps that I use on my phone. I believe Verizon's focus for years with improving their network was first targeting voice coverage and after that targeting any area of the country where their customers were getting less than 1mbps download speed. They may have since increased that 1mbps threshold to something higher and are now focused on small cells to fix coverage issues deep within buildings and between their macro sites.
  12. Where did you get that 63% number from? I have rarely seen any home with more than 3 wires attached to it. Those wires are electric, telephone and cable. There is no effective internet over electric lines so that leaves 2 wired internet providers at most for homes that are wired for both telephone and cable. I live in a suburb of Chicago which is a heavily populated area and there are only 2 wired internet providers both of which have messed with internet traffic in the past. Both of which have low caps for the speed of the connections they offer and where they promote their own content by making it exempt from caps while doing everything they can to limit access to their competitor's content. Are you just arguing for the sake of arguing or do you not believe the evidence that ISPs effectively have monopolies and have a desire to increase their revenue while disadvantaging their competitors? This fundamental business desire is in conflict with the open internet that has existed for the past 20 years. As they started to put those business desires into practice, Net Neutrality was proposed to make them common carriers. This is not about regulating the internet, it is about keeping it open.

    Sprint 2017 handset SRLTE mode survey/discussion

    I think all Apple CDMA enabled iPhones sold in the past few years use SRLTE by default. Apple patented their implementation of SRLTE a few years ago which may be a little different than the way other phones use SRLTE.
  14. I care that I can send and receive whatever traffic I want on my connection without my ISP deciding what I should be able to use. I use my wired connection for work and for entertainment. I transfer a lot of data and I do not want anyone messing with my traffic in any way. The FCC has decided that with 3 nationwide wireless providers there would not be enough competition but with most areas having 2 wired ISPs or less, that the monopoly practices of the wired ISPs are just fine with them.
  15. Yes, they were starting to mess with traffic and that is why Net Neutrality was put into effect. It started with a demand that Netflix pay your ISP to carry high speed traffic to you over the ISP interconnections without being throttled. They also started messing with torrent traffic to keep people from using torrenting programs. Now they have low caps on high speed connections while exempting their own content from their caps or forcing their competitors streaming products to lower bandwidth so they have an inferior product. I have to pay $30 extra each month to so that I can go over 1TB of data download in a household were I often work from home and all our entertainment is streaming. Net Neutrality was supposed to be about forcing ISPs to be dumb carriers and not allowing them to mess with any traffic that they carry. Without it we will continue down the path of monopoly ISPs deciding what internet traffic to pass to and from their customers and at what speed.
