  1. The 5x5 will be more than enough for text messaging and hundreds or thousands of simultaneous phone calls per satellite cell. As long as they prioritize phone calls with text messaging without media including data apps such as iMessage, RCS, WhatApp, etc. second, they can put all the other types of media including MMS and app-based photo attachments, etc. and all other data types in lowest priority. People will get terrible data performance but general data might work or might not. That is more than enough for many people in an emergency.
  2. It appears that T-Mobile is quickly enabling the new cellular bandwidth but for some sites they may have to wait an unknown amount of time for the backhaul to be increased so that users actually see the faster speeds.
  3. I wish they could get the FCC to agree to allow them to keep it if they run old technologies such as analog, GSM, 2G, and 3G with open access for a small fee from all providers on it for compatibility with old IOT devices. Although if those old devices are not configured to use 800mhz, it won't help.
  4. In a venue such as that, a huge number of people will be taking pictures and videos and uploading them. Upload speed becomes very important and 200mbps may struggle when a large number of customers are uploading at the same time.
  5. A bucket list item for me would be to watch the "big game" inside the Sphere. That thing looks amazing.
  6. https://9to5mac.com/2023/11/16/apple-rcs-coming-to-iphone/ - RCS support coming in IOS 18. This will be in addition to iMessage and SMS.
  7. I would think tower leases that they are still paying for but no longer using. As those useless leases expire they get to realize additional savings from the merger.
  8. I would like to see a technical explanation as to how 5G network slicing is supposed to work with Net Neutrality. My read on this which may be incorrect is that network slicing would only be allowed under net neutrality so long as the slice of the network is a private network but that seems to contradict the ability for the general public to use a public facing app from the app store that will run over the network slice.
  9. We do not care if they were hacked or just incompetent which they claim they were in this case. Either way they are very careless and have no comprehension of basic data security with our personal information and are putting us as risk.
  10. https://www.crowncastle.com/communities/small-cell-information has a good write up on small cells, how they work and what they look like. They will not show up on apps like cellmapper until they are turned on so that users can connect to them. After that it requires someone running the app to connect to them before they get mapped. That can be from a few days to months after they are installed.
  11. From what I have seen on this subject, it involves both tower and data center server shutdowns during times of low usage. The data center work is common by many companies where they find areas that have multiple servers providing capacity and have some of them go to sleep when they are not needed and wake up when they are needed. The sleep and wake cycles can be time based or based on actual usage or some combination of the two. Tower coverage is not supposed to be impacted by these shutdowns but capacity definitely is. This means that a computer program running in their data center will be analyzing each tower's usage and will attempt to detect the speed that all the users are getting from that tower and will track if some part of the higher frequency bandwidth is not being used. If those frequencies have not been used for some period of time it will be shutdown and if the lower bandwidths get to some level of higher usage, they will started back up. The sleep and wake cycles can be time based or based on actual usage or some combination of the two.
  12. I would expect Dish to purchase the 800mhz and use that spectrum as the collateral for much of the purchase. It may be that T-Mobile would even hold the loan on this deal with the requirement that if Dish defaults on the loan, T-Mobile would get the spectrum back.
