  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. I switched to DirecTV Now streaming a year ago along with Netflix and Hulu. DirecTV Now was unreliable for the first 6 months but it has been quite good since then. It has a very good channel selection and I get a discount with my wife's AT&T mobile unlimited plan. At the moment it is still limited to two streams at a time but early next year they are planning to offer DVR functionality and additional streams that may be premium add-ons for additional money each month. Two streams at a time is not really a problem for my family because many of the network apps work with it such as HBO Go. The streams on the network apps do not count as one of your active streams. The picture quality is excellent but it eats a lot of data to get high picture quality on a television. They recommend a minimum 12 mbps download speed to watch the highest quality as the app streams the video in bursts greater than 6 mbps. If you have a slower connection and you are using your connection for anything else at the same time, the picture can buffer and switch you to a lower quality.
  13. VOIP uses 8kbps to 90kbps up while you are talking and that same speed down while the other person is talking. The actual bandwidth is based on the algorithm used with higher numbers of bits required for HD voice and lower for regular voice and more bits are used for a larger range of sounds. The algorithms for streaming audio which VOIP uses automatically adjust the amount of data used based on the range of sounds they are trying to send at that time. VoLTE is normally in the 16kbps to 32kbps range. 0.5mbps is the same as 500kb/s just to give you some idea of how much bandwidth you really have available. At the highest possible quality and bit rate of 64kbps to 90kbps (which are almost never used on VoLTE connections) , near CD quality music could be broadcast over your VOIP call. Those speeds are still less than 20% of your 0.5mbps speed or less than 5% if you are using closer to the minimum amount of standard voice bandwidth.
  14. It is interesting that they will ramp up spending about the projected time they can start adding 800mhz in the Mexico border exclusion area. If I was Sprint, I would pour money into Southern California to get 800mhz going asap. That is a massive population area that is currently suffering without a low band.
  15. I always wonder what people are doing on their mobile connection that say that an upload over 5mb/s is not fast enough. The pictured upload is faster than my real world speed tests on my home internet connection rated at 75mb/s down and 8mb/s up. Any time my mobile connection is faster than my home internet, it is perfectly fine with me. Extremely fast upload is for hosting servers or uploading very large files. Neither of those are what mobile connections are designed for. That upload speed should do everything you want to do on a mobile connection quite quickly.

  17. I would think that tethering it would significantly limit where it could fly. No one is going to allow a tethered vehicle to fly above a stadium as an example.
  18. I assume the plan is that a new flying micro cell would be launched into the air before the old flying micro cell depleted its batteries. Then the old flying micro cell one would be flown down to a manned charging station, where its batteries would be exchanged with fully charged ones. The manned charging station could be located at a COW (Cell on Wheels) site that was providing coverage from one side of the event and providing the bandwidth for the flying micro cell. Think of how nice the coverage would be with COWs surrounding a large event with flying micro cells providing coverage in the middle from above.
  19. The total percent of subscribers graph shows everything you need to know about the current US wireless industry. Verizon has ~35%, AT&T has ~35%, and all the other competitors are competing for the final 25% to 30%. This also means that 70% to 75% of all the profits are split between AT&T and Verizon which gives them the money to keep deploying and keeps them with much larger, stronger networks. If AT&T and Verizon can each afford to spend $10 billion+ on their networks each year, no smaller competitor can hope to keep up.
  20. Sprint has some of the best spectrum for dense areas with their huge amount of Sprint2500/2600mhz. T-Mobile has some of the best wide area rural coverage and in building spectrum with the combination of Tmobile600/Tmobile700/Sprint800mhz. The combination of the two companies plus some mid-band coverage should allow them to provide great coverage. Keep 1 CDMA voice carrier and 1 GSM voice carrier and re-farm everything else to voLTE. The network should be able to perform well for years.
  21. I wonder if in a future software update will they allow Magic Boxes to daisy chain off each other in certain conditions to extend coverage out? I believe the hardware has the capability of doing this. One of the conditions I am thinking of is when a Magic Box can see no macro band 41 and no macro band 25 but can see a signal from a functioning integrated into the network Magic Box. Another is when two or more magic boxes are located at the same address such as a large building and one gets a b41 signal but another can only get a b25 signal. Another daisy chain possibility is when a LTE femtocell is present.
  22. If a merger is approved, the first thing that will likely happen is native roaming on each other's network. For T-Mobile users it is as simple as enabling VoLTE and connecting on any Sprint LTE Bands that their device is able to use when T-Mobile LTE is not available. At the start, IP addresses are not portable between the two carriers so they would likely use T-Mobile LTE first and only use Sprint LTE if no T-Mobile LTE was available. For Sprint users, it is a little more complicated but would likely involve connecting to T-Mobile LTE for data when Sprint LTE is not available and enabling T-Mobile GSM calling whenever CDMA voice calling is not available. This would have to stay in place for a while since VoLTE (Calling Plus) is not available on most devices and is not yet ready for mass roll-out. At the start, IP addresses are not portable between the two carriers so they would likely use Sprint LTE first and only use T-Mobile LTE if no Sprint LTE was available. Over time, Sprint phones would get T-Mobile VoLTE. The Sprint voice core centers would be switched over to handle T-Mobile calling technologies. The data core centers would be configured for common portable IP addresses so that movement between the two LTE networks would be seamless.
  23. I got that email today as well. They must have mass mailed everyone who ordered one who has not yet been contacted.
