[SOLVED] Intel 3x3 wireless

[wm3797]

Do 3x3 MIMO intel wifi wireless cards exist? I can't seem to find any

Intel Puma Peak cards are 3 by 3 but they are not AC. I had one. Search for Intel Centrino Ultimate-N 6300.

It's a shame they don't exist. I think there are lots of people that want that extra speed.

To make use of MIMO 3x3 you need a whole empty spectrum for yourself. That is not very common unless your nearest neighbor is 1/2 a mile away... Broadcom BCM4378 is the latest and greatest you can find IMO.

Oh I see. I want to ask if I have TWO laptops that each have a 2x2 MIMO, and the router is a 3x3, how will the data flow

They should talk to each other directly (unless isolated by the AP) if that is the question.
The data rates are dependent on several aspects and are far beyond a simple question.
Think of WiFi as a corridor with an endless amount of doors where people talk to each other. Only one can talk at any given moment.

If you are looking for 3x3 laptop cards the much larger problem is your laptop likely only has 2 antenna and adding a antenna is many times not possible. In addition to work well the placement and spacing of the 3 antenna is important. This is likely why you see almost all laptops with only 2 antenna.

They are cheap actually. Not a big deal. Just no use for it. Most applications need line stability more than bandwidth. 3x3 requires 3 channels to work as one aggregated wide channel which is wideband. If one of the channels gets interference the coding scheme changes (to get over the noise) and reduces throughput. You also face things such as packet loss and jitter. Anything over stable 100 Mbit when it is stable is already good enough for most users and is better than 1Gbit with packet loss and jitter.

I did not mean you could not get antenna it is finding a way to get it installed. There is almost no room to add one. Even replacing them is hard you have to get one the same physical dimensions. And this is after you find a way to dissemble the screen, they are starting to glue them like cell phones and you need to use a heat gun to take them apart.

Did not take one apart in a while. The antennas are usually on the top corners of the screen, I did once glue one of those in the middle behind the LCD to have 3. Again, there is no point of having 3 now as the radio is so saturated.
