Qualcomm's Fast X12 LTE Modem is Appropriate Candidate for iPhone 7

Actually that's the exact opposite of what would happen.

The technologies in the Snapdragon X12 modem are designed to increase network capacity. The faster speeds that users experience is actually a by-product of that.

As a matter of fact, the more the mix of users in the cell that shift to higher capability modems, the better the user experience becomes for all users in the cell. That's because people with the faster modems occupy the air for less time to get their downloads and uploads done, so they free up the network for other users faster. So even if you have a phone with an older, less capable modem, your actual speeds go up.

This is the root cause for the pursuit of these ever more capable modems and network features.

That is a very good point actually. Good job, sir.

Throttled time! whoo hoo!

we have 3 grandfathered unlimited data plans on Verizon and we all go over 40gb a month on each line and don't get throttled

I use everything online and have a YouTube red account and stream all my playlists as YouTube videos in my car and at gym everyday with out any issues.im at 35gb now with 10 days left on my cycle and just hit 35 down and 5 up on speed test net

Is it att? Surprised that you didn't get throttled.

we are on Verizon

oh okay. well...that's great then.

I think the big issue here for the mobile networks is streaming which would be a continual pull of data from the tower until either the stream is over or until the end user stops it. A lot of streaming apps will not buffer the whole video and instead continually buffer it throughout the whole playback process.

I think the big issue here for the mobile networks is streaming which would be a continual pull of data from the tower until either the stream is over or until the end user stops it. A lot of streaming apps will not buffer the whole video and instead continually buffer it throughout the whole playback process.

Actually, these capacity-enhancing technologies help with the streaming scenario as well. Here's why.

On each LTE connection, the tower has a fixed number of "resource blocks" to assign to all the users connected to it. There are 100 resource blocks. You can think of it as a 100 lane highway. Depending on how much traffic you're consuming, the tower will assign you a certain number of lanes to get your data down to you from the Internet. Then when you're done, it'll re-assign those lanes to somebody else's traffic.

The more lanes you get, the faster your download speeds would be. But that's not the only thing that determines speed. For example, if we're still using the highway analogy, let's say that on each one of the lanes you're assigned, the tower is sending trucks carrying packages, and those packages represent the bits that make up the movie you're streaming. The number of trucks the tower sends is a factor in determining how quickly the the packages will be delivered to you...but also, the number of packages each truck is carrying will play a factor is well. If, for example, I can cram more packages into a truck, then I need to send fewer trucks, and thus occupy fewer lanes, to get you the exact same amount of data. That would free up some lanes for me as the tower to send data to another user. That analogy for example illustrates the E benefit of something like 256-QAM, which allows the tower to pack 33% more bits into each LTE transmission. If you have a phone with the X12 LTE modem, then you will use fewer resource blocks from the network to stream the exact same movie at the exact same bitrate. That frees up resources from the tower that it can then assign to a different phone to finish downloading a file faster. Or, it creates more room for other people to also stream videos at the same time.

Hope this helps.

Interesting. Thank you very much for that. Also, welcome to MacRumors.
