The speed you get is far more dependent on the signal strength, not the speed of the modem. That only comes into play when you have a perfect signal, so realist

The speed you get is far more dependent on the signal strength, not the speed of the modem. That only comes into play when you have a perfect signal, so realistically (as a perfect signal is rare), modem speed plays almost no part in speed limitations.
- joecool1029 8y agoIt does come into play in weak signal situations. Consider support for more spatial streams (4x4 mimo) helps with reception in cell edge areas and when noise levels are high or multipath interference is a factor. Also every modem/antenna pairing has limits programmed in where they'll drop a cell or switch to a different layer (band) with less bandwidth. No iphone uses 4x4 mimo. Maybe for battery, or maybe Jony couldn't make it pleasing looking enough in the X, but its lack is very much is a factor affecting quality of service including speed in non-ideal environments.
- innagadadavida 8y agoAre there any reliable objective numbers and comparisons for this? While mimo is a great technology, it is trivial to “hold your iPhone right way” and get the same benefits, I feel mimo has become a marketing ploy for companies to push their latest without any perceptible impact to users.
- joecool1029 8y agoHere’s some testing on the S7 with T-Mobile using 4x4: http://cellularinsights.com/samsung-galaxy-s7-the-first-4x4-mimo-smartphone/ http://cellularinsights.com/samsung-galaxy-s7-the-first-4x4-... There’s a perceptable impact to users with mimi and it specifically takes advantage of multipath. This is not a case of marketing fluff. However, 256QAM is something you’ll probably only see in ideal situations as it requires very good signal, that’s the one that edged out gigabit speeds in the lab.
